Coating formula: a new type of silicon soluble adhesive architectural coating formula

Core tip: silica sol, also known as silicate water glass, is an inorganic polymer polymetasilicic acid colloid solution with water as the dispersion phase, odorless and tasteless, with a considerable specific surface area, the particle itself is colorless and transparent, and does not affect the color of the coating The application of silica sol in water-based coating can improve the performance of coating, cover up the defects of coating itself, have certain permeability to substrate, enhance adhesion, the smaller the particle size of film-forming material, the smaller the viscosity, and the better the permeability; at the same time, organic coating forms a complete waterproof coating on the surface of substrate, the larger the particle size of film-forming material, which is not easy to penetrate, and has good waterproof performance after film-forming Adding silica sol to prepare organic-no Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Coating home news: silica sol, also known as silicate water glass, is an inorganic polymer polymetasilicic acid colloid solution with water as the dispersion phase, odorless and tasteless, with a considerable specific surface area, and the particles themselves are colorless and transparent, which does not affect the nature of the coating The application of silica sol in water-based coating can improve the performance of coating, cover up the defects of coating itself, have certain permeability to the substrate, enhance the adhesion, the smaller the film-forming particle size, the smaller the viscosity, the better the permeability; at the same time, organic coating forms a complete waterproof on the surface of substrate Coating, film-forming material particle size is large, not easy to penetrate, waterproof after film-forming, adding silica sol, preparation of organic-inorganic composite coating can meet such requirements 1 The formulation of silica soluble building coating: raw material weight / g raw material weight / g water 20 dispersant 5040 0.3 n-octanol 0.2 wollastonite 10 talcum powder 10 titanium dioxide 3 heavy calcium 15 kaolin 11 modified silica sol (20% - 40%) 30 hydroxymethylcellulose 0.2 antiseptic JMP 0.32 Preparation process: (1) mix deionized water, dispersant and defoamer evenly; (2) Take the metered pigment and filler, pass the water vapor to make it fully wetted: (3) slowly add the substances in (2) into (1) in the mixing state, and the mixture obtained is dispersed, sanded and filtered at high speed, and then add the metered modified silica sol and thickener under the mixing, and finally add the appropriate amount of preservative under the mixing, so as to obtain the finished product (the paint formula in this paper is for reference only) paint home is focused on the news and information of coating, diatom mud, paint coating, coating process, fire retardant coating, and coating, diatom mud, paint coating, coating process, decoration knowledge and decoration effect map of fire retardant coating,
