Problems solved by technology

[0005] In building construction, the quality of putty products is often poor, and in a long-term humid environment, the wall will cause the base concrete layer to return to alkali due to moisture, making the putty unable to attach to the wall surface normally, and even pulverize and fall off

Abstract

The invention provides putty powder as well as a preparation method and application thereof. The putty powder is prepared from the following components in parts by weight: 15 to 35 parts of Portland cement, 10 to 30 parts of ground calcium carbonate, 3 to 10 parts of talcum powder, 1 to 3 parts of composite nano ferrotitanium powder, 3 to 8 parts of corrosion-resistant agent, 1 to 3 parts of feldspar powder, 1.5 to 3 parts of alkali-proof agent, 0.5 to 1.5 parts of vinyl acetate-ethylene copolymer emulsion, 0.3 to 0.5 part of glass fiber, 0.2 to 0.5 part of wood fiber and 0.2 to 0.5 part of amylase. According to the putty powder disclosed by the invention, the alkali-proof agent can prevent a cement base layer on the surface of a wall body to which putty is attached from separating out an alkaline material, and the adhesive force between a putty wall surface and the cement base layer is strengthened. The corrosion-resistant agent can form an ion mixed film and prevent invasion of alkaline materials, and the alkali-resistant agent and the corrosion-resistant agent act together, so that the alkali resistance of the putty powder painted on the surface of a wall body can be effectively improved, and powdering and falling of the putty caused by alkali efflorescence of the wall body due to the humid environment are prevented.

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 one of the most commonly used building decoration materials, and its main components are talcum powder and glue. Putty, to take a step further, is a kind of base material for leveling the wall, which lays a good foundation for future decoration (painting and wallpaper). [0003] Putty is divided into two kinds: putty inside wall and putty on exterior wall. External wall putty can resist wind and sun, so it has good gelation, high strength and low environmental index. The comprehensive index of putty in the inner wall is good, and it is hygienic and environmentally friendly. Therefore, the inner wall is not for external use and the outer wall is not for internal use. [0004] Putties are usually based o...
