Problems solved by technology

[0004] However, this patent application has the following deficiencies: first, formaldehyde is added in its raw materials, but it is mentioned in its effect that it can remove formaldehyde; secondly, it uses talcum powder as the main raw material, and talcum powder is only a filler, although Carboxymethyl cellulose is added to the formula, but its proportion is very small, so it is easy to cause the putty coating to powder, crack, hollow and fall off

Abstract

The invention discloses anti-stripping exterior wall putty powder. The anti-stripping exterior wall putty powder is prepared from the following raw materials in parts by weight: 40-44 parts of diatomite, 6-8 parts of talcum powder, 2-4 parts of white bentonite, 12-14 parts of white portland cement, 7-9 parts of high-strength gypsum powder, 2-3 parts of hydroxypropyl methyl cellulose and 6-8 parts of titanium dioxide. The anti-stripping exterior wall putty powder disclosed by the invention does not contain harmful substances. As the components of the anti-stripping exterior wall putty powder are adjusted, the bonding strength of the putty is enhanced, and the anti-stripping property of the putty is improved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an anti-flaking exterior wall putty powder. Background technique [0002] The quality of exterior wall putty directly affects the decoration and durability of the paint finish. The use of exterior wall putty or interior wall putty with poor performance will eventually lead to wall peeling, hollowing, and cracking soon after the project is delivered. Partial or large-area coatings lose their 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 s...
