Abstract

The invention relates to interior wall putty powder which comprises the following components in parts by weight: 980-1020 parts of heavy calcium carbonate powder, 8-10 parts of pre-gelatinized starch,2-5 parts of polyvinyl alcohol powder and 4.5-5.5 parts of cellulose ether. According to the putty powder, the polyvinyl alcohol powder and the cellulose ether are added into the heavy calcium carbonate powder to prepare the interior wall putty powder, common putty powder with the quality far superior to that of starch and 821 can be obtained, meanwhile, the hardness of the interior wall putty powder is between that of ash calcium-based putty and that of starch putty, and the interior wall putty powder further has excellent batch scraping performance, adhesive force, flexibility, polishing fineness and durability far better than that of the ash calcium-based putty and the starch putty, and simple and feasible formula components.

Description

technical field [0001] The invention belongs to the technical field of building materials, and particularly relates to an interior wall putty powder. Background technique [0002] Putty powder is a decorative material for smoothing the surface of the wall. It is made of inorganic gel materials as aggregates, and is finely processed with bonding materials and other additives. It is an indispensable product before painting. A surface filling material used for pretreatment of the construction surface, the purpose is to fill the pores of the construction surface and correct the curve deviation of the construction surface, so as to lay a good foundation for obtaining a uniform and smooth paint surface. Putty powder is divided into two types: exterior wall and interior wall. The quality of interior wall putty powder directly affects the decorative effect of interior wall painting. The existing interior wall putty powder has complex components. SUMMARY OF THE INVENTION [0003]...
