Owing to compare with natural marble, outward appearance and the workability of excellence and the relative high advantage of light weight intensity of the gracefulness of common artificial marble with the acrylic resin preparation, it has been applied in multiple uses such as comprising tank, sales counter table, dining table, decorative article.Yet, compare with grouan with natural marble, limitation possesses skills during the simple combination performance different pattern of acrylic artificial marble opaque fragment commonly used in using this area.
Usually prepare based on the step of the artificial marble of vinylformic acid and unsaturated ester as follows: for example the hyperbaric inorganic filler that has of aluminium hydroxide, lime carbonate, silicon-dioxide and silicon is starched with the monomer of for example methyl methacrylate (MMA) and polymethylmethacrylate (PMMA) or unsaturated polyester (UPE) polymkeric substance and is mixed as main ingredient; in mixture, add pigment and for example multiple additives of polymerization starter, linking agent, chain-transfer agent and coupling agent; molded mixture on mould or successive steel band, and solidify molded mixture.
Pigment and fragment are mainly used in to artificial marble CF are provided.The polymethylmethacrylate (PMMA) that uses at present in this area can be as the main ingredient of these fragments.If necessary, can use for example thermoplastic resin of polyvinyl chloride (PVC) and polystyrene (PS), or the thermosetting resin of Resins, epoxy and unsaturated polyester for example.Preparation process as the fragment of artificial marble is as follows: add multiple additives in resin, or the mixture of at least a pigment and multiple additives, use the identical or close method of the method commonly used to prepare flat board, and pulverize final artificial marble and make it have different grain size with prepare artificial marble.
In order to give the glitter of artificial marble (for example engineered stone) under illumination, the method for using is that a kind of material (for example pearl) is mixed with matrix resin at present, or uses a kind of metal (for example aluminium)-transfer materials as fragment.Someone advises using mirror to realize the method for depth perception and reflecting effect.Yet this method can not obtain desired result fully.
When the material preparation of using metal for example or minute surface during based on the artificial marble of acrylic resin or unsaturated polyester (UPE) resin, because the high specific gravity of these materials, can not polish them, and since their processibility of difference almost can not use.On the other hand, when using low specific gravity material to prepare fragment,, therefore make transparency variation unfriendly, and can not fully obtain desired result because they comprise inorganic filler.
Use the fragment of for example metal, pearl and the preparation of sheet glass material these materials of surface display, therefore when realizing depth perception, have limitation at final artificial marble.
Publication number be the Korean Patent of 2004-0059913 disclosed a kind of with use in the fragment fragment as feature based on acrylic acid artificial marble.Yet the acrylic synthetic marble of disclosure is owing to comprising the problem that inorganic filler has the transparency variation in its component, and realizing aspect the depth perception limitation being arranged owing to scintillation material is arranged on the surface of final artificial marble.
Number of registration is 400, it is the artificial marble of feature with the fragment in the formation fragment that 814 Korean Utility Model has disclosed a kind of, wherein will form the marble chip of patterning in solidified acrylic syrup matrix, and scintillation material will be adhered on the particle based on unsaturated polyester based on the particle adhesion of unsaturated polyester.Yet owing to comprise inorganic filler in its component, this artificial marble has relatively poor transparency, and has relatively poor depth perception owing to transparent material is exposed to its surface.
Publication number is that the Japanese Patent of 2001-205750 has disclosed a kind of artificial marble that comprises the molded articles in clear gel coating, artificial marble layer and middle layer, and wherein the middle layer comprises and is arranged on two-layer intermediary gloss paint.Just can obtain artificial marble by applying gloss layer and transparent layer in its surface simply, and therefore not be directly related to the low specific gravity material of the use of feature of the present invention based on high specific gravity chips.
The 3rd, 648, No. 592 Japanese Patent has disclosed the artificial marble that a kind of use has the multiple fragment of different specific weight and shape.This artificial marble is not directly related to low specific gravity material and the reflecting effect of the use of feature of the present invention based on high specific gravity chips.
Publication number is that the Japanese Patent of 1999-314942 has disclosed with being selected from the painted glass powder of at least a compound in transition metal and the rare earth metal, makes the plasticity glass powder crystallization of 0.1～20wt% simultaneously.This invention only provides the painted glass powder as the weighting material of artificial marble, is not directly related to the use and the reflecting effect based on the low specific gravity material of high specific gravity chips of feature of the present invention.
Publication number is that the Japanese Patent of 1995-2556 has disclosed the resin combination that is used for artificial marble.By mixed packing with comprise that the unsaturated polyester resin of unsaturated polyester and polymerization single polymerization monomer prepares this resin combination.Weighting material is that the main ingredient by 1～30wt% is that luminous weighting material of the energy of mica powder of coated by titanium dioxide and the inorganic filler of 70～99wt% are formed.This invention only relates to weighting material, is not directly related to low specific gravity material and the reflecting effect of the use of feature of the present invention based on high specific gravity chips.
Summary of the invention
Technical problem
Therefore, one of purpose of the present invention is that low density material is applied in the artificial marble.
Another object of the present invention is the reflecting effect and the flicker effect of giving artificial marble degree of depth transparent feel, therefore demonstrates texture and gloss with the natural marble basically identical.
Another purpose of the present invention provides the preparation method of a kind of artificial marble and this artificial marble, wherein in order to use transparent low specific gravity material as fragment, the high specific gravity material is incorporated in the fragment with integrally-built form, and use this fragment during artificial marble in preparation, therefore by being included in transparent feel and the reflecting effect that fragment in the artificial marble demonstrates the degree of depth.
Technical scheme
According to a scheme of the present invention, the invention provides a kind of by high specific gravity layer, low specific gravity layer and the reflector layer that comprises light reflecting material with this order reflective fragment of high specific gravity of constituting of lamination from top to bottom, low specific gravity layer wherein has the proportion lower than artificial marble proportion, high specific gravity layer has the proportion higher than artificial marble proportion, and reflector layer comprises light reflecting material.
The present invention proposes by transfer printing or metal refining on transparent low specific gravity layer, perhaps apply preparations such as pearl or sheet glass and can show the fragment of flicker effect, and with the whole transparent low specific gravity layer that forms of the proportion regulating course that comprises hyperbaric weighting material, therefore use the proportion regulating course to solve specific gravity difference between fragment and the artificial marble.
According to the present invention, the specific gravity difference between the material compositions of the artificial marble of reflective fragment of high specific gravity and use fragment is no more than 0.5, and preferably is no more than 0.2.
The present invention has the high specific gravity chips of making and uses the minimized feature of specific gravity difference between the material compositions of artificial marble of this fragment.When high specific gravity chips and material compositions do not have specific gravity difference, promptly have equal specific gravity each other, perhaps be no more than 0.2 specific gravity difference, fragment can not separate from material compositions.
