Abstract

The invention discloses putty powder for exterior walls, and relates to the field of coatings. The putty powder for the exterior walls comprises the following raw materials: white portland cement, light calcium carbonate powder, talcum powder, ash-calcium-powder, quartz powder, GN-1008 glue powder, an efficient general dispersant P-30A, polyacrylamide, organosilicone solid defoamer, a mould inhibitor BJ-75, easily dispersed fibers and nanometer zinc oxide. According to the invention, the light calcium carbonate powder, ash-calcium-powder and an anionic surfactant are added in the putty powder for the exterior walls, and can be mutually infiltrated and react to improve the stability and hardness of a putty powder layer; in addition, the quartz powder is added to enhance the hardness of the putty powder more effectively.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an exterior wall putty powder. Background technique [0002] Putty is a kind of decorative coagulation material for leveling the surface of the wall. It is a thick paste paint and an indispensable product before the paint is painted. The main purpose of applying putty is to fill the pores of the construction surface and correct the defects of the construction surface. Curve deviation, laying the foundation for obtaining a uniform and smooth paint surface. However, the traditional exterior wall putty powder often has peeling, cracking, and falling off due to the outdoor environment. Contents of the invention [0003] The problem to be solved by the present invention is to provide a waterproof, high hardness and anti-crack exterior wall putty powder. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: a...
