Study on scrubbing resistance and viscosity stability of inorganic silicate coatings
LIU Mulin
Abstract：In view of the unstable problems of scrubbing resistance and viscosity of inorganic silicate coatings,the curing mechanism of potassium silicate and the effects of different types of potassium silicate,polymer emulsion,additives and pigments on the scrubbing resistance and viscosity stability of inorganic silicate coating were discussed.The results show that the inorganic sili-cate coating is prepared with inorganic modified potassium silicate K39 as inorganic base material,styrene acrylic emulsion TL615D as auxiliary base material,comb hydrophobic acrylate 1990 as dispersant,anionic cellulose S30000 as thicker,calcium carbonate A and titanium dioxide R2195 as pigments and fillers,the data of scrubbing resistance before and after heat storage are 9000 and 7000 times respectively,and the viscosity data are 80 KU and 88 KU respectively,which has the best stability and could adapt to the performance requirements of coatings used in current architectural building.
