Abstract

The invention provides putty powder as well as a preparation method and application thereof. The putty powder comprises the following components in parts by weight: 15-35 parts of Portland cement, 10-30 parts of ground calcium carbonate, 3-10 parts of talcum powder, 3-8 parts of fluorgypsum, 4.5-9 parts of a composite moisture-proof agent, 0.5-1.5 parts of a redispersible polymerizing agent and 0.2-0.5 part of a wood fiber starch compound. According to the putty powder disclosed by the invention, the composite moisture-proof agent is added, so the putty powder has excellent moisture-proof performance and anti-cracking performance, and the service life of the putty powder after the putty powder coats the surface of a wall body is prolonged.

Description

technical field [0001] The invention relates to the technical field of filling slurry, in particular to a putty powder, and at the same time, the invention also relates to a preparation method and application of the putty powder. Background technique [0002] Putty powder is a building decoration material, the main components are talcum powder and glue. Putty powder is a kind of base material used for wall repair and leveling, which lays the foundation for the next step of decoration. According to different use environments, putty powder is divided into two types: interior wall and exterior wall. The exterior wall putty powder should resist wind and sun. , so the glue is strong, the strength is high, and the environmental index is slightly lower, while the comprehensive index of the putty powder for the inner wall is better, and it is healthy and environmentally friendly, so the inner wall is not for external use, and the outer wall is not for internal use. [0003] The wat...
