Problems solved by technology

[0003] The traditional exterior wall putty powder is often made of inorganic gel material as the base material, combined with bonding materials and other additives, which cannot play the role of auxiliary heat insulation. At the same time, the existing exterior wall putty powder Whiteness and texture, as well as crack resistance, penetration resistance, and waterproof capabilities need to be strengthened

Abstract

The invention relates to the technical field of putty powder and discloses external wall insulation waterproof putty powder and a production process thereof. The external wall insulation waterproof putty powder is mainly prepared from the following raw materials in parts by weight: 300 to 500kg of white cement, 70 to 90kg of quartz sand, 40 to 60kg of talcum powder, 130 to 145kg of heavy calcium powder stone, 200 to 400kg of hollow glass spheres, 3 to 8kg of early strength agent, 3 to 5kg of hydroxypropyl methyl cellulose, 14 to 18kg of latex powder, 3 to 7kg of wood fiber, 3 to 5kg of polypropylene and 6 to 10kg of water repellent. The external wall insulation putty powder has a function of assisting a heat-insulated coating in insulating heat, has higher whiteness, texture and anti-cracking and anti-osmosis capabilities.

Description

technical field [0001] The invention relates to the technical field of putty powder, in particular to a thermal insulation and waterproof putty powder for external walls and a production process thereof. Background technique [0002] Putty powder is a kind of building decoration material, which is used as a base material for wall repair and leveling, and lays a good foundation for the next step of decoration (painting and wallpaper). Putty is divided into two types: exterior wall putty and exterior wall putty. Exterior wall putty can resist wind and sun, so it has good gelation, high strength, and slightly low environmental index. The comprehensive index of exterior wall putty is good, and it is healthy and environmentally friendly. [0003] The traditional exterior wall putty powder is often made of inorganic gel material as the base material, combined with bonding materials and other additives, which cannot play the role of auxiliary heat insulation. At the same time, the ...
