Abstract

The invention discloses waterproof alkali-resistant outer wall putty powder, and relates to the technical field of a putty powder building material. The waterproof alkali-resistant outer wall putty powder is prepared from the following raw materials: asbestos flotation tailings, bauxite, brucite velvet, bismuth vanadate, portland-pozzolana cement 32.5R, HPMC with 100,000 viscosity, a dispersing agent FT-78, composite glue powder, a water reducing agent, a coupling agent, a water repellent and magnetized water. The putty powder disclosed by the invention is comprehensively and remarkably improved in terms of physical property, water resistance, alkali resistance, flexibility, shielding property, mould resistance and the like; compared with the prior art, the putty powder is obviously improved and has good applicability and long service life.

Description

technical field [0001] The invention relates to the technical field of putty powder building materials, in particular to a waterproof and alkali-resistant exterior wall 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). 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. Putties are usually based on gypsum or cement, so rough surfaces are easier to bond firmly. ...
