According to a preferred embodiment of the present invention, the above-mentioned earthen materials for eco-friendly architectural finishing materials of the present invention (as of 28 days old) are measured by KS F 4716, the adhesion strength of 0.7 to 1.5 Mpa, The removal rate of volatile organic compounds (VOCs) can be over 80%.

The waxy composition for eco-friendly architectural finishing material of the present invention and the waxy material for eco-friendly architectural finishing material including the waxy composition for eco-friendly architectural finishing agent of the present invention are not only excellent in adhesion strength, but also for environmentally friendly architectural finishing materials which do not cause diseases such as atopy, asthma, And to provide a green building finish material containing the same.

Hereinafter, the present invention will be described in more detail.

As described above, the prior art eco-friendly varnish compositions for indoor finishes are not only low in the removal efficiency of harmful substances emitted from the varnish composition itself for interior finishing materials, but are also superior to conventional varnish compositions for interior finishing materials which do not contain eco-friendly materials There is a problem that adhesion is poor.

Accordingly, the present invention includes a mixture containing gypsum and blast furnace slag, an aggregate, a veneer impregnated aggregate and a powdered acrylic resin, wherein 90 to 110 parts by weight of aggregate, 0.5 to 5 parts by weight of pasty impregnated aggregate, And 0.1 to 1.5 parts by weight of a powdery acrylic resin, to solve the above-mentioned problems.

As a result, it is possible to provide an environmentally friendly building sealant composition that does not cause diseases such as atopy, asthma, and sick house syndrome due to harmful substances as well as excellent adhesion strength, and an environmentally friendly building finish material containing the same .

The green building composition for eco-friendly architectural finishing of the present invention includes a mixture including gypsum and blast furnace slag, aggregate, aggregate impregnated with wood vinegar and powdered acrylic resin.

First, the green building finishing composition of the present invention does not include Portland cement (KS L 5201), which is generally used as a building material composition for building finishing materials.

The Portland cement is obtained by mixing raw materials including silica, aluminum, iron oxide and lime as main components in an appropriate ratio, firing the mixture, and adding the appropriate amount of gypsum to the obtained clinker. The types of portland cement are classified into one kind of ordinary Portland cement, two kinds of thermal Portland cement, three kinds of crude steel Portland cement, four kinds of low heat portland cement and five kinds of sulfate Portland cement.

In this way, many chemicals contained in portland cement release toxic substances such as formaldehyde, volatile organic compounds (VOC), toluene, xylene, carbon dioxide (CO ₂ ), benzene, The inventive eco-friendly architectural finish composition does not include Portland cement, so that the release of such harmful substances can be minimized.

Further, since the present invention includes a mixture that can replace the role of portland cement as described above, the environmentally friendly finishing composition for building finishing material functions as a binder in the interior finishing composition for environmentally friendly finishing materials to improve the bonding strength .

The mixture comprises gypsum and blast furnace slag.

The gypsum is an eco-friendly building material much superior to cement, and can serve as a curing agent for the environmentally friendly building finishing material composition of the present invention.

The gypsum may include at least one selected from semi-gypsum and diatomaceous earth, and may preferably include alpha-hemihydrate gypsum.

The semi-gypsum is made by absorbing moisture in the atmosphere after heating the alumite mined from open-air light or underground light. At this time, the alumite is put into a pressure cooker, and a small amount of organic acid is added in order to promote crystallization, and then water vapor and water are added and heated to produce alpha-hemihydrate gypsum. In addition, it is possible to produce beta-hemihydrate gypsum by crushing the alumite and then putting it in a pot to perform primary dewatering at about 130 ° C and then raising the temperature to 190 ° C for secondary dewatering.

Specifically, alpha type hemihydrate gypsum can be produced by autoclave or hydrothermal synthesis, and beta type hemihydrate gypsum can be synthesized only by drying at a certain temperature range.

Since the alpha type hemihydrate gypsum has superior hardening time, tensile strength and compressive strength than the excretory type hemihydrate gypsum, the greenhouse composition for eco-friendly construction finishing material of the present invention can contain alum-type hemihydrate gypsum in gypsum, Lt; / RTI >

The blast furnace slag is in the form of a fine powder and is included in the green building composition for eco-friendly construction finishing material of the present invention to improve the compressive strength. Since the blast furnace slag is produced by drying and crushing and is vitrified by quenching, high.

The blast furnace slag may be classified into one blast furnace fine powder, two blast furnace fine powders and three blast furnace fine powders according to the quality standard KS F 2563, and the blast furnace slag of the present invention may be divided into the blast furnace fine powder It may contain one kind, two kinds and three kinds, preferably three kinds.

The gypsum and blast furnace slag may be added to the green building finishing composition of the present invention at a weight ratio of 1: 0.08 to 0.28, preferably 0.11 to 0.25. If the blast furnace slag is less than 0.08 weight ratio The problem of dust generation on the surface may occur, and if it exceeds 0.28 weight ratio, the pores may be filled excessively, resulting in a problem of poor adsorption performance.

Next, the aggregate is chemically stable as a construction minerals material that can be formed into a lump by a binder such as concrete, mortar, orbital dough, and bituminous mixture.

Aggregates include crushed rock, sand, gravel and slag, which are present in rivers, forests, shared water surfaces, other ground, underground, etc., and are classified into coarse aggregates with a size of 5 mm or more and fine aggregates with a size of 5 mm or less And the aggregate of the present invention may include sand having an average particle size of 0.12 mm to 0.8 mm, preferably 0.3 mm to 0.6 mm. If the average particle diameter of the aggregate is less than 0.12 mm, the workability may be lowered due to an increase in the amount of the aggregate, and shrinkage cracking may occur. If the aggregate particle diameter exceeds 0.8 mm, A problem of protrusion may occur.

The aggregate may contain 90 to 110 parts by weight, preferably 95 to 105 parts by weight, based on 100 parts by weight of the mixture. If the aggregate is contained in an amount of less than 90 parts by weight based on 100 parts by weight of the mixture, there may be a problem that the strength of the green building finish composition for environmentally friendly finish of the present invention is lowered. If the aggregate exceeds 110 parts by weight, have.

The veneer impregnated aggregate refers to an aggregate prepared by being immersed in a vinegar solution.

Specifically, the pasty impregnated aggregate is immersed in the aggregate at a weight ratio of 1: 0.5 to 1: 1, and if the pasture is immersed in an amount of less than 0.5 wt% based on the weight ratio of the aggregate 1, the air quality control performance by the pastilles is expected And if it is immersed in an amount exceeding 1 part by weight, the cost is increased, the economical efficiency is lowered, and the drying time is required for a long time.

The vinegar liquid is obtained by liquefying the smoke from the process of making charcoal from wood and then removing the toxic and harmful substances by aging for 6 months or longer. It has a pale red color and strong smell. The method of sampling is to burn wood, and when yellowish white smoke comes out, it leaves only small vents, closes the kiln inlet, and the smoke comes into contact with the outside air and naturally cools down and collects the falling liquid. The temperature of the charcoal flue chimney is best when it is 85 ~ 120 ℃, and the collected vinegar is aged and separated for more than 6 months. Thus, the wood vinegar is separated into water-soluble and oil-soluble liquids. The water-soluble liquids can be used as wood vinegar, and the oil-soluble liquids can be used for industrial purposes.

The aggregate of the veneer-impregnated aggregate contains at least one zeolite having an average particle diameter of 15 to 27.5 탆, preferably 18 to 27.5 탆, and an activated carbon having an average particle size of 2.5 to 17 탆, preferably 2.5 to 14 탆 If a common aggregate such as zeolite having an average particle diameter as described above and an aggregate other than the above-mentioned average particle size other than the activated carbon is used as the aggregate of the vinegar-impregnated aggregate, the impregnation of the vinegar The effect due to the wood vinegar can not be expected.

The veneer impregnated aggregate may contain zeolite and activated carbon at a weight ratio of 1: 0.8-1.2, preferably 1: 0.9-1.1, and if the activated carbon is contained at a weight ratio of zeolite of less than 0.8, There is a possibility that the VOC adsorption performance may be deteriorated. If it exceeds 1.2 weight ratio, the workability of the finish material may deteriorate due to the deterioration of the workability.

The veneer impregnated aggregate may be coated with an acrylic resin.

Specifically, the coating liquid containing the solvent and the acrylic resin may be sprayed onto the surface of the wood vinegar-impregnated aggregate to form a coating film composed of the acrylic resin.

The acrylic resin may contain 7 to 10.5% by weight, preferably 8 to 10% by weight of solids. If the content of the solid content in the acrylic resin is less than 7% by weight, the coating composition can not be properly formed on the surface of the veneer impregnated aggregate, and the strength of the green building finish material composition of the present invention can be reduced. If the content of the solid content is more than 10.5% by weight, the aggregation of the wood-based impregnated aggregate may be caused by the bonding between the acrylic resins, resulting in a decrease in strength due to poor filling.

The acrylic resin is a synthetic organic polymer material, which can be referred to as a thermoplastic resin since fluidity is generated by heat. The acrylic resin commonly used in eco-friendly architectural finish compositions may be used without limitation, and preferably the acrylic resin is a hydrophobic acrylic monomer comprising an alkyl acrylate or alkyl methacrylate, an acrylamide compound, A hydrophilic monomer containing at least one monomer selected from the group consisting of a monocarboxylic acid compound and an aminoethyl acrylate compound, an ethylene oxide-added acrylic monomer, an unsaturated carboxylic acid monomer, and an acrylic monomer containing a hydroxyl group or a glycidyl group and a polymerization initiator can do. At this time, the molecular weight may be 100-100.

The solvent may be selected from the group consisting of water, heptane, octane, toluene, hydrocarbon solvents such as xylene and mineral spirits; Ester solvents such as ethyl acetate, n-butyl acetate, isobutyl acetate, methyl cellosolve acetate and butyl carbitol acetate; Ketone solvents such as methyl ethyl ketone, methyl isobutyl ketone and diisobutyl ketone; Alcohol solvents such as methanol, ethanol, isopropanol, n-butanol and sec-butanol; n-butyl ether, dioxane, ether solvents such as ethylene glycol monomethyl ether and ethylene glycol monoethyl ether.

The veneer impregnated aggregate may comprise 0.5 to 5 parts by weight, preferably 1 to 3 parts by weight, based on 100 parts by weight of the mixture. If the veneer impregnated aggregate is contained in an amount of less than 0.5 part by weight based on 100 parts by weight of the mixture, The efficiency of the eco-friendly timber composition according to the present invention is low due to the low content of wood vinegar and the ability to remove toxic substances. When the amount exceeds 5 parts by weight, the strength of the eco-friendly timber composition may deteriorate.

Meanwhile, the aggregate and the veneer impregnated aggregate contained in the viscous material composition for eco-friendly architectural finishing material of the present invention may be contained in a weight ratio of 1: 0.005 to 0.04, preferably 0.01: 0.031. If the veneer impregnated aggregate contains less than 0.005 weight ratio of the aggregate, the effect of improving the air quality by the vinegar may not be expected. If the aggregate exceeds 0.04 weight ratio, The workability is deteriorated and the problem of the soundness of the construction can not be expected.

Next, the green building material composition for eco-friendly architectural finishing according to the present invention may contain 0.1 to 1.5 parts by weight, preferably 0.5 to 1.0 part by weight, of powdered acrylic resin with respect to 100 parts by weight of the mixture.

The powdered acrylic resin serves as a blending polymer for improving various physical properties in the green building finishing composition of the present invention. If the powdered acrylic resin is contained in an amount of less than 0.1 part by weight based on 100 parts by weight of the mixture, There arises a problem of generation of dust on the surface of the ash, and if it is contained in excess of 1.5 parts by weight, voids on the surface of the wax can be filled, which may result in deterioration of the adsorption performance of harmful substances.

The material of the powdered acrylic resin may be the same as or different from the material of the acrylic resin mentioned above.

Next, the green building material composition for eco-friendly architectural finishing according to the present invention may further contain a thickener and water for 100 parts by weight of the mixture.

The thickener can adjust the viscosity of the eco-friendly wax for building finishing according to the construction conditions, and can prevent the sudden evaporation of water and keep it constant.

The thickening agent may include at least one selected from the group consisting of methyl cellulose, ethyl cellulose and polysaccharide thickener, preferably methyl cellulose.

The thickener may be contained in an amount of 0.8 to 1.2 parts by weight, preferably 0.9 to 1.1 parts by weight, based on 100 parts by weight of the mixture. If the thickener is contained in an amount of less than 0.8 part by weight based on 100 parts by weight of the mixture, rapid evaporation of water of the environmentally friendly waxy material of the present invention can not be prevented. If the thickening agent is contained in an amount exceeding 1.2 parts by weight, the viscosity of the environmentally friendly waxy material of the present invention is increased. It causes a lot of difficulties.

Water may be contained in an amount of 48 to 72 parts by weight, preferably 54 to 66 parts by weight, based on 100 parts by weight of the mixture. If water is contained in an amount of less than 48 parts by weight with respect to 100 parts by weight of cement, the workability may be deteriorated. If the water is contained in an amount exceeding 72 parts by weight, a problem of flowing down may occur when the environmentally friendly varnish is applied.

Meanwhile, the eco-friendly architectural finish material of the present invention includes the above-described eco-friendly timber composition.

As a result, it is possible to obtain an adhesion strength of 0.7 ~ 1.5 Mpa when measured according to KS F 4716 standard on the 28th day of age according to the present invention.

In addition, the green building finishing material of the present invention may have a removal rate of volatile organic compounds (VOCs) of 80% or more as measured by KS L 1204 on the 28th of August.

In conclusion, the eco-friendly architectural finish material of the present invention not only has excellent adhesion strength but also is excellent in the removal efficiency of harmful substances such as volatile organic compounds and does not cause diseases such as atopy, asthma and sick house syndrome caused by harmful substances .

In the meantime, the method for manufacturing the green building finishing material of the present invention comprises the steps of: (1) a step of producing a wood vinegar impregnated aggregate; and (2) mixing gypsum, blast furnace slag, aggregate and powdered acrylic resin, Thereby manufacturing an eco-friendly finish material varnish.

First, in step (1), the aggregate is immersed in the wood vinegar to prepare wood vinegar-impregnated aggregate. Specifically, the aggregate is immersed in the wood vinegar for 25 to 35 minutes, the aggregate is taken out from the wood vinegar, and then dried at 90 to 110 ° C, preferably at 100 to 105 ° C to produce wood vinegar-impregnated aggregate.

The wood vinegar-impregnated aggregate may be immersed in the aggregate at a weight ratio of 1: 0.5 to 1, preferably 1: 0.5 to 0.8, of the wood vinegar.

In this case, the immersion may be carried out by immersing the material in various liquids, by attaching the liquid to the surface of the material or by penetrating the liquid into the inside of the pores, or by soaking the material in water or by wetting the stem of the plant fiber with water, I can tell the job.

Further, if the drying temperature is lower than 90 ° C, the drying time may become longer. If the drying temperature exceeds 110 ° C, the wood pulp adsorbed on the aggregate may be volatilized.

Next, the veneer impregnated aggregate is coated with an acrylic resin. Specifically, a coating solution containing a solvent and an acrylic resin may be sprayed onto the surface of the vinegar-impregnated aggregate to form a coating film. At this time, the acrylic resin may contain 7 to 10.5% by weight, preferably 8 to 10% by weight of solids.

Finally, in step (2), gypsum, blast furnace slag, aggregate, and powdered acrylic resin are added to the veneer impregnated aggregate produced in the step (1), followed by mixing to produce an eco-friendly varnish for building finishing materials.

In this case, the compositions to be mixed may include 90 to 110 parts by weight of the aggregate, 0.5 to 5 parts by weight of the vinegar impregnated aggregate, and 0.1 to 1.5 parts by weight of the acrylic resin, based on 100 parts by weight of the mixture including gypsum and blast furnace slag.

In step (2), the mixing may be performed for 30 to 90 seconds, preferably 45 to 75 rpm, at 50 to 70 rpm. If the mixing is performed for less than 30 seconds, the eco- There is a problem that the compositions contained in the resin composition are not mixed uniformly.

On the other hand, the eco-friendly wax material prepared in step (2) may further contain 0.8 to 1.2 parts by weight, preferably 0.9 to 1.1 parts by weight, of a thickening agent based on 100 parts by weight of the mixture.

The eco-friendly wax material prepared in the step (2) may further contain 48 to 72 parts by weight, preferably 54 to 66 parts by weight, of water relative to 100 parts by weight of the mixture.
