A kind of preparation method of aqueous granite-simulating paint
Technical field
The present invention relates to technical field of coatings, more particularly relate to a kind of preparation method of aqueous granite-simulating paint.
Background technology
At present, water-borne coatings uses quite extensive in the wall ground of buildings is decorated, it is low that it has a cost, easy construction, good decorating effect, be convenient to safeguard advantages such as cleaning, and granite-simulating paint has the granitic decorative effect of substituting, being subjected to market welcomes, just like application number is 200410040715.6, the applying date is on 09 17th, 2004, denomination of invention is artificial grantie inner, external wall coating and preparation method's patent application, and its moiety comprises cement, 500 order marble flours and polyvinyl alcohol building glue, and the pigment of corresponding color.Its preparation method comprises and mixes stirring preparation slurry, spraying slurry, coating is dry and spraying transparent resin operation.This method is prepared into has the polyester artificial marble effect after coating uses, and the preparation method is fairly simple, and is applied widely, but cost is higher relatively, and hardness is not enough, though cement can play the effect that reduces cost, but corrosion resistance is relatively poor, and luminosity is inconsistent, and decorative effect has much room for improvement.
Summary of the invention
Purpose of the present invention is exactly in order to solve the deficiency of prior art, and a kind of preparation method who exactly likes granite, appearance is hard, cost is low aqueous granite-simulating paint who provides.
The present invention adopts following technical solution to realize above-mentioned purpose:
A kind of preparation method of aqueous granite-simulating paint is characterized in that, its preparation method's step is; At first, prepare colored slurry, select the mastic coatings of high-quality pure third or organosilicon crylic acid latex allotment for use, the color that furnishing needs, use special-purpose coating machine, by required 0.5~0.8mm thickness blade coating in last on the colour bar cloth of stripping machine, after drying or drying, take paint film off, be broken into the color sheet that requires size with crusher; Auxiliary agents such as water, dispersion agent, PH conditioning agent, antimildew disinfectant under high-speed stirring, are scattered in color sheet in the water, form colour slurry that do not advise, that vary in size;
Then, ratio mixes above-mentioned colored slurry 15~40%, pure-acrylic emulsion 20~60%, quartz sand 0~60% and the auxiliary agent 0.5~2% of different colours by weight, promptly gets the water-based granite coatings.
The beneficial effect that the present invention adopts above-mentioned technical solution to reach is:
One, this coatings decoration is effective, has adopted colored slurry, and color change according to actual needs is abundant, uses the back moulding true to nature, as bright as a sixpence, and the texture texture-rich can substitute granite fully.
Two, easy construction is applicable to any building surface, safely and fast.
Three, safe in utilization, radiationless, environmental protection, weather resisteant can be good.
Four, production technique of the present invention is fairly simple, low cost, and the coating of moulding is obviously compared from heavy and light with granite slab.
Embodiment
Aqueous granite-simulating paint of the present invention, its preparation method's step is; At first, colored slurry in the preparation coating raw material, select the mastic coatings of high-quality pure third or organosilicon crylic acid latex allotment for use, the needed color of furnishing, adopt special-purpose coating machine again, slurry is pressed 0.8mm thickness blade coating on the colour bar cloth of stripping machine, through after drying or drying, take paint film off, be broken into the color sheet that requires size with crusher; Auxiliary agents such as standby water, dispersion agent, PH conditioning agent, antimildew disinfectant under high-speed stirring, are scattered in color sheet in the water, mix to form colour slurry erratic, that vary in size; Then, ratio mixes the above-mentioned colored slurry 30% of different colours, pure-acrylic emulsion 40%, quartz sand 28% and various auxiliary agent 2% by weight, promptly gets this water-based granite coatings.
In the use, its construction method step is:
(1) surface of wall is handled well on request, pulled on anti-crack mastic;
(2) alkali resistant waterproof priming paint of brushing;
(3) one anti-skidding aggregate of spraying;
(4) spray two road water-based granite coatings with special-purpose spray gun, adopt not sticking grey cutter to criticize and flatten;
(5) treat that spraying layer of transparent varnish after coating is done gets final product.
The present invention is not limited to the foregoing description, more than shown only be preferred embodiment of the present invention, can not limit the present invention's interest field with this, therefore the equivalent variations of being done according to the present patent application claim still belongs to the scope that the present invention is contained.
