Abstract
The invention discloses a plant fiber cement composite ribbon board with an excellent sound absorption and insulation effect and a manufacturing method thereof. The manufacturing method comprises the following steps: firstly, performing pretreatment on the surfaces of plant fibers by adopting a river character fluorine carbon emulsion resin impregnation treatment process, so as to enable the inner and outer surfaces of the plant fibers to be coated with a layer of thin polymer film, then spraying linseed oil mist to enable each of the whole fibers to be compact, improved in the water resisting property and have a certain rigidity; secondly, adding coal ash, modifying coal ash to replace part of cement, therefore the production of calcium hydroxide after hydration is reduced, and the corrosion resistance of plant fibers is improved. According to the plant fiber cement composite ribbon board with the excellent sound absorption and insulation effect, provided by the invention, the prepared plant fiber cement composite ribbon board has the advantages of being sound-absorbing, sound-proof, strong in compactness, good in permeability, excellent in durability and low in cost, improves the comprehensive utilization level of plant fibers and reduces serious damage caused by improper treatment to waste resources.
Description
Technical field
The present invention relates to material of construction material technical field, be specifically related to good plant fiber-cement composite strip plate of a kind of soundproof effect that absorbs sound and preparation method thereof.
Background technology
Since entering the nineties, in the selection of living environment, people have been not content with general has it to occupy, but is pursuing material of construction and the new building materials of environmental harmony type with natural characteristic.Environmental harmony type building materials must meet heat preservation energy-saving, sound absorption sound insulation, water-proof fire-retardant, nonpoisonous and tasteless, lightweight, the characteristic such as high-strength, safe, plant fiber-cement composite strip plate is exactly a kind of novel environmental harmony type material of construction, selected vegetable fibre refers to annual fiber, mainly refers to that agricultural crop straw is as cornstalk, straw, Cotton Stalk, hemp stalk etc.
At China's yearly plant abundance, be inexhaustible, nexhaustible raw material, their lifetime is shorter, does not have too large purposes after withered.These agricultural crop straws through cut off hammer broken after obtained vegetable fibre feature be that length-to-diameter ratio is large, specific tenacity is high, specific surface area is large, density is low and biodegradable, have that cost is low, tensile strength advantages of higher in addition, replace timber to make cementitious composite batten strongthener, in use unharmful substance and obnoxious flavour generate.
But the alkaline attack effect of vegetable fibre extract to the anticoagulation of cement and cement-hydrate all limits the application of plant fiber-cement composite strip plate, show: the high alkalinity liquid phase in cement matrix hole has erosion action to vegetable fibre, thus affects the weather resistance of composite strip plate; Vegetable fibre has very high water-intake rate, the declining to a great extent of flexural tensile strength and Young's modulus after volume change can be caused to cause plant fiber-cement composite strip plate to make moist, and composite strip plate is distorted distortion, even ftractures; Vegetable fibre because there is depolymerization, making its polymerization degree decline and causing the corresponding reduction of its tensile strength under microbial process.For solving the problems of the prior art, need to carry out modification to existing plant fibre surface and reduce the alkalescence of gelling material.
Summary of the invention
Object of the present invention is just to provide good plant fiber-cement composite strip plate of a kind of soundproof effect that absorbs sound and preparation method thereof, to overcome the deficiencies in the prior art.
The object of the present invention is achieved like this:
The plant fiber-cement composite strip plate that a kind of soundproof effect that absorbs sound is good, it is characterized in that, be made up of the raw material of following weight part: vegetable fibre 20-25, bamboo fibers 7-11, silicate cement 25-35, flyash 36-46, vermiculite 14-20, Vltra tears 0.1-0.3, silicon carbide 0.5-0.8, Tai-Ace S 150 0.4-0.7, linseed oil 4-6, water-base fluorocarbon emulsion resin 13-16, triethylene glycol two 2-ethylhexoate 8-12, Zinc Pyrithione 0.03-0.06, water are appropriate.
The preparation method of the plant fiber-cement composite strip plate that described a kind of soundproof effect that absorbs sound is good, is characterized in that comprising the following steps:
(1) vegetable fibre, bamboo fibers are put into 105 DEG C drying for baking oven about 3-4 hour, room temperature is dried, rap that to remove to pectin and be crushed to diameter be 3-6mm again with skin hammer, being placed on mass concentration is soak 24 hours in the water-base fluorocarbon emulsion resin of 10%, press dry post-drying, air blast to the state of seething sprays into vaporific linseed oil, dries;
(2) vermiculite is calcined 1-2 hour at 610-720 DEG C, cooling adds flyash agitation grinding 30-40 minute, adds silicon carbide and is warming up to 220-270 DEG C of stirring 5-10 minute, be cooled to 50-80 DEG C, add triethylene glycol two 2-ethylhexoate to continue to stir 3-5 minute, be cooled to room temperature, dry porphyrize;
(3) Tai-Ace S 150 be dissolved in water and stir 10-15 minute, add step (1), (2) reaction mass stirring and evenly mixing, add silicate cement and other remaining components again and stir 20-30 minute, it is shaping to add forming machine, obtains finished product successively after 20-30h through cutting, the demoulding, natural curing.
The present invention has following beneficial effect: it is easy that the present invention prepares simple operations, first water-base fluorocarbon emulsion resin impregnation treatment process is taked to make the surfaces externally and internally of vegetable fibre be enclosed with one layer of polymeric film to plant fibre surface pre-treatment, spray vaporific linseed oil again, make whole fibre dense and obtain certain rigidity, and water tolerance improves; Secondly flyash is added and in addition modification replaces part of cement, the growing amount of calcium hydroxide after minimizing aquation, improve the corrosion resistance of vegetable fibre, choose the water cement ratio of 0.42 simultaneously, obtained plant fiber-cement composite strip plate has sound absorption sound insulation, density is strong, good penetrability, weather resistance are good, low cost and other advantages, improve the level of comprehensive utilization of vegetable fibre, reduce because waste resource deals with the grievous injury caused improperly.
