Multifunctional protection paste for outside wall

Abstract

An outside wall multi-functional protective slurry is composed of A and B components, in which A component contains elastical latex, cellulose aether, crack resistance fiber, lignified fiber, dispersant, anti mildew agent; B A component contains cement, perlite, girasol pearl, pulverized fuel ash, water reducer. The inventive outside wall multi-functional protective slurry has a perfect crack resistance and a high cohesive strength. The slurry matches with the outside wall external heat retaining and has a high cost performance. The invention accords to the industry standards of construction industry of JG / T157-2004 <<outside wall architectural used putty>> and outside wall heat retaining plaster standard and it has a certain heat insulation and heat retaining function.

Description

technical field [0001] The invention relates to a slurry, in particular to an exterior wall slurry, in particular to a multifunctional protection slurry for an exterior wall which not only has the function of putty but also has the function of external heat preservation protection mortar. Background technique [0002] Putty is a surface filling material for pretreatment of the construction surface. Its main purpose is to fill the pores of the construction surface and correct the curve deviation of the construction surface, laying a good foundation for obtaining a uniform, smooth or decorative paint surface. In addition, putty also has the functions of making up for cracks in the base layer and enhancing adhesion. [0003] The use of exterior wall putty is something in recent years. Initially, exterior wall finishing materials seldom use putty, and most of them are directly painted on the base material. When there are holes or cracks in the substrate, scrape the putty locall...

AI Technical Summary

Problems solved by technology

As a result, the amount of protective mortar layer is large, increasing its own weight; the thermal conductivity of the inner insulation layer is too different, there is no transition layer, the temperature difference changes are concentrated in the protective layer, and the aging cracks of the protective layer are accelerated; in order to make up for the defects of the mortar protective layer, in Putty is used on the protective layer, which not only increases the cost, but also increases the self-weight. At the same time, if the putty is not selected properly, it will cause more problems.
