Attapulgite putty powder for exterior wall

Abstract

The invention discloses lacquer putty powder for the external wall of a concavo-convex rod. The technical proposal thereof comprises the key points that: the lacquer putty powder for the external wall of the concavo-convex rod consists of a purified concavo-convex rod, white bentonite, white Portland cement, high strength gypsum powder, hydroxypropyl methylcellulose and rutile type titanium dioxide. The method for producing the lacquer putty powder for the external wall of the concavo-convex rod is to prepare, crush, grind and pack the raw materials to a finished product of the lacquer putty powder for the external wall of the concavo-convex rod, wherein the lacquer putty powder for the external wall of the concavo-convex rod is placed in a vessel to be immersed by water for 5 to 30 minutes, and the proportion of the lacquer putty powder for the external wall of the concavo-convex rod to the water is 1:0.5-1:4; after being sufficiently and evenly stirred, the powder can be applied for scraping and coating. The lacquer putty powder for the external wall of the concavo-convex rod has the characteristics of good cohesive property, strong adhesive attraction, stable filming performance, high strength, long service life, water resistance, crack resistance, powder falling prevention, firm viscosity with coatings and paint conservation, and is applicable to coating project of construction.

Description

technical field [0001] The invention relates to coatings, in particular to an attapulgite exterior wall putty powder. Background technique [0002] The quality of the putty directly affects the decoration and durability of the paint finish. The use of products with poor performance or external use of interior wall putty often leads to wall shedding, hollowing, cracking, partial or large area shortly after the project is delivered for use. The coating loses its original decoration and protection functions, seriously affecting the normal use of buildings. The quality requirements of putty for external walls of construction projects are mainly reflected in the indicators such as bond strength, initial crack resistance and dynamic crack resistance. Bond strength is one of the important technical indicators. In construction, the poor quality of putty products often causes the putty to fail to adhere to the wall surface normally, causing the surface layer of the putty to pulveriz...

Problems solved by technology

[0004] The disadvantage of the above-mentioned patent is that this technology uses talcum powder as the main raw material to produce "interior and exterior wall putty paste and powder that can purify the air", and talcum powder is only a filler, although carboxymethyl is added to the formula Base cellulose, but its proportion is very small, so it is easy to cause the putty coating to powder, crack, hollow and fall off
