Substrate conditioning material composition and substrate conditioning material

摘要

We found a new material that can be used as a substitute for the vinegar-based bibeova-based resin, which was considered to be suitable as a component of the base preparation for gypsum board, and obtained the same effect with less use than the system using vinegar-based biveova-based resin. In addition, the problem of smoothness of the base preparation material due to shrinkage after curing is also improved, which is suitable when making a wall surface with gypsum board, used as a base preparation material by mixing with water, At least one selected from the group consisting of water gypsum, calcium carbonate and dihydrate gypsum is used as a main material, and 0.3 to 10 parts by mass of a vinyl acetate-acrylic resin with respect to 100 parts by mass of the main material, cellulosic Providing a base preparation composition comprising 0.05 to 1 part by weight of a thickener.
