(2) first material II is joined in high-speed mixer, then add clorafin, bay diacid, xanthan gum and antimonous oxide, add material I again after mixing 5-10min, mixture is warming up to 70-80 DEG C of mixing 10-15min, cooling down subsequently, obtains material II;
(3) be first added in ball mill by organically-modified diatom soil, bamboo fibers powder, light calcium carbonate, hydrogenated castor oil and water, add material II after ball milling 10-15min, continue to be milled to granularity and be less than 10 μm, then filter, filtrate carries out tub packaging.
Described polymer emulsion is selected from the mixture of a kind of in benzene emulsion, ethene-vinyl acetate copolymer emulsion and polyaminoester emulsion or any two kinds.
Described aerosil is white rouge aerogel.
The invention has the beneficial effects as follows:
(1) take water as solvent, nontoxic, free from extraneous odour, free from environmental pollution, construction safety is convenient;
(2) have that cohesiveness is good, the feature of strong adhesion, water-fast, wear-resisting, long service life, there is not shedding phenomenon after coating metope, and can with other coating secure bond;
(3) soundproof effect is good, is applicable to the places such as residential building, hotel, hotel, conference hall;
(4) easy to use, after opening packaging, mixing can use.
