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 a preparation method and a using method of anti-stripping exterior wall putty powder. The preparation method comprises the following steps of: step one, adding 6-8 parts of talcum powder, 2-4 parts of white bentonite and 12-14 parts of white portland cement to a pulverizer so as to be pulverized to obtain powder less than 150 meshes; step two, mixing the obtained powder, 40-44 parts of diatomite, 7-9 parts of high-strength gypsum powder and 6-8 parts of titanium dioxide, placing the mixture in a pulverizer so as to be pulverized for 10-15 minutes, then adding 2-3 parts of hydroxypropyl methyl cellulose, and pulverizing for 5-10 minutes again; step three, sieving the powder obtained in the step two by using a screen mesh with 320 meshes, wherein sieve residue is the anti-stripping exterior wall putty powder. The using method comprises the following steps of: placing the anti-stripping exterior wall putty powder in a container, adding water to the putty powder in the proportion of the exterior wall putty powder to the water being 10: (2-3), adding a right amount of pigment according to the color of an exterior wall, soaking for 40-60 minutes, and then stirring the mixture for 5-10 minutes by adopting a stirrer for blade coating.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a method for preparing and using 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 wal...
