A kind of Artificial stone inorganic adhesive and preparation method thereof
[technical field]
The present invention relates to artificial stone, particularly relate to inorganic adhesive of a kind of artificial stone and preparation method thereof.
[background technology]
In recent years, flourish along with decorations industry, inner-outer wall stone material consumption constantly increases, civilian stone material is divided into lithotome and artificial stone, lithotome is based on granite, marble and jade, artificial stone's aggregate and adhesives are by stirring, vibrations, evacuation, compressing, and after requirement of strength to be achieved, saw blade, polishing, polishing i.e. prepared artificial stone.China more than 90% artificial stone all uses resin as adhesives at present, uses the stone material that resin-made obtains to have the features such as bright-colored, highly polished, uniform color, high intensity, but resin belongs to organic material, and weatherability is poor, it is impossible in outdoor application;And resin has penetrating odor and corrosivity with accelerator, production process does not meet environmental requirement.
In order to solve this problem, Chinese invention patent application " inorganic artificial combining stone and preparation method thereof " (January 10 2010 applying date, number of patent application: in CN201210005418.2) has melted the manufacture method of a kind of inorganic artificial combining stone, wherein, inorganic cementing agent is metakaolin, silicate base solution, adjustable solidification agent, inorganic pigment and fiber.The artificial synthesis stone of this invention not only has a dicoration matched in excellence or beauty with resin type artificial stone, and asepsis environment-protecting, with low cost;Tolerate the corrosion of most of acid-alkali salt, high temperature resistant, excellent durability, it will be apparent that preventing the whiting accumulation of salt in the surface soil phenomenon under life-time service, contamination resistance is also stronger.But this application product early strength is low, curing cycle length, wear no resistance.Due to not cement.Artificial stone pH value is low, and the easy dusting in surface, anti-carbonation properties is bad.
Chinese invention patent application " manufacture method of artificial stone " (April 28 2011 applying date, number of patent application: CN201180021777.0) disclose the production method of a kind of artificial stone, wherein, cementing material is made up of blast-furnace cinder micro-powder end, alkali-activator, Portland cement etc..This application product pluses and minuses are similar with previous patent.
Chinese invention patent application CN200810212034.1(publication date JIUYUE in 2008 12 days,) disclosing formula and the preparation technology of a kind of artificial stone, its formula consists of: according to percentage by weight cement 20-25%, Gypsum Fibrosum 5-10%, silicon ash 10-15%, lithium carbonate 0.1-0.5%, extraordinary water reducer 1-3%, waterproofing agent 1-2%, pigment 5-10%, sand 40-55%.The present invention passes through to prepare product into mould, the demoulding, maintenance, polishing cutting, post-treating and other steps, has tasteless, nontoxic, radiationless, and fire prevention, intensity height, good decorating effect, technique is simple, the features such as cost is low.But the method using a number of silicon ash, color is deeper, it is impossible to produce white and light color artificial stone.
