Sandy paint
Technical field
The present invention relates to a kind of material of construction, relate in particular to a kind of sandy paint.
Background technology
At present mainly contain two kinds of making methods in building and the very universal sandy paint of decoration occasions, a kind of to be the stone sand that forms with light calcium carbonate and marble, granite, rhombspar, quartzite pulverizing mix as the aggregate of coating and light calcium carbonate and binding agent; Another kind method is that the binding agent with the natural sand of 40-90% and 10-60% mixes.That the coating that these two kinds of methods are made has is fire-retardant preferably, waterproof and decoration function, and texture, hardness are all close with lithotome, have very strong decorative effect.But first method is to adopt the light calcium carbonate of some amount to use as filler, there are three big shortcomings in well-known light calcium carbonate: the one, and oil number is big, exceed more than 50% than general stone flour, when being used in coating, will consume a lot of binding agents and could satisfy corresponding strength, cost is increased as filler; The 2nd, acid resistance is poor, meets acid and decomposes, and is unfavorable for using under area that acid rain occurs or sour environment; The 3rd, lime carbonate is the high energy consumption product, to use high-temperature firing from Wingdale to making lime, need a large amount of energy, and make light calcium carbonate again through operations such as washing, drying, pulverizing from lime, need a large amount of energy equally, do not resemble the natural stone-powder and just can be made into as long as once pulverize, through measuring and calculating, make one ton of energy that light calcium carbonate consumed and to make powder more than 10 tons, therefore with the filler of light calcium carbonate, be rational inadequately from the angle of Financial cost and environmental protection as sandy paint.And press the sandy paint that second method is made, owing to be to adopt granulate material double as aggregate and filler, after the film forming, owing to there is bigger space between sand grains and the sand grains, the easy permeation coating of moisture, wetting metope damage the body of wall of building, and also are further improved.
Summary of the invention
Deficiency at prior art exists the object of the present invention is to provide a kind of sandy paint that meets environmental protection and energy-conservation requirement and improve impervious water function.
The objective of the invention is to be achieved through the following technical solutions:
A kind of sandy paint, form by granular aggregates, opaque filler, binding agent and auxiliary agent, the mixture of one or more in the fine powder that wherein said opaque filler is ground into by natural stone-powder, chemical breeze, rubber powder, fine coal ashes and by waste is formed, and its fineness is 130 orders-1000 orders.The opaque filler is the 1-45% of coating weight, and the fineness of described granulated aggregate is 10 orders-130 orders, and consumption is the 40-85% of coating weight, and binding agent is the 8-40% of coating weight, and auxiliary agent is the 1-20% of coating weight.
Described binding agent is one or more the mixture in petroleum derivative synthetic resins, natural oil ester derivative, natural resin derivative and the mineral binder bond.
The mixture of one or more in particle, rubber grain or the fly ash grain that described granular aggregates is 10 orders-130 purpose stone sand, natural sand, sand burning, perlite, brickbat, glass cullet, broken ceramics, be ground into by waste.
Described auxiliary agent is made up of in coating toughener, linking agent, thickening material, film coalescence aid, fungusproof anti-corrosion agent, defoamer, promotor, wetting agent, thinner and the deionized water one or more.
Adopted one or more the opaque fillers formed in the fine powder that is ground into by natural stone-powder, chemical breeze, rubber powder, fine coal ashes and waste in the sandy paint of the present invention, made product sandy paint of the present invention not only save the energy but also improved the impervious water function of coating.
