Problems solved by technology

The currently known putty is composed of talcum powder, carboxymethyl cellulose, 107 glue and white latex. This kind of putty has low bonding strength, poor water resistance and large shrinkage, so it is easy to hollow, fall off and crack; Or it is made of resin emulsion with fillers, which greatly improves the adhesion, but due to the thin coating, it requires high flatness of the base surface, poor ability to fill holes, and cannot withstand various climate changes.

Abstract

The strong mastic for new and old cement and concrete wall has high weather resistance, and is compounded with weather resistant polymer resin A, stuffing, assistant, diluent and weather resistant polymer resin B in certain weight proportion. It has high waterproof performance, high adhesion force, stable chemical property, high mildew resistance and some self-cleaning function and can adapt weather change. It has the advantages of both organic and inorganic paint.

Description

Technical field: [0001] The invention relates to a paint putty for plastering interior and exterior walls, in particular to a strong putty with high weather resistance for new and old cement walls and concrete walls. Background technique: [0002] Usually there are various defects in the plastering base surface of the inner and outer walls, and the putty must be scraped before the paint is applied. The currently known putty is composed of talcum powder, carboxymethyl cellulose, 107 glue and white latex. This kind of putty has low bonding strength, poor water resistance and large shrinkage, so it is easy to hollow, fall off and crack; Or it is made of resin emulsion with fillers, which greatly improves the adhesion, but due to the thin coating, it requires high flatness of the base surface, poor ability to fill holes, and cannot withstand various climate changes. Invention content: [0003] The purpose of the present invention is to provide a strong putty for old and new c...
