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. Therefore, 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 and poor ability to fill holes.

Abstract

The strong permeability elastic waterproof mastic for new and old cement and concrete wall is compounded with No.8 cement base high adhesive glug polymer latex of 50% concentration and water in certain weight proportion. It can permeate into cement base layer and well combine with paint layer to resist cracking of the cement base layer. It has the advantages of both organic and inorganic paint.

Description

Technical field: [0001] The invention relates to a base material putty for plastering exterior walls, in particular to a highly permeable elastic waterproof putty 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. Currently known putty is composed of talcum powder, carboxymethyl cellulose, 107 glue and white latex, etc. 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 has high requirements for the flatness of the base surface and poor ability to fill voids. Invention content: [0003] The object of the present invention is to provide a highly permeable elastic waterproof putty with high permeabili...
