Outer wall elastic emulsion with lotus effect and preparing method of outer wall elastic emulsion

Abstract

The invention aims at overcoming the defects in the prior art, and provides outer wall elastic emulsion with a lotus effect and a preparing method of the outer wall elastic emulsion. The outer wall elastic emulsion has excellent normal-temperature and low-temperature elasticity and also has good stain resistance. The outer wall elastic emulsion with the lotus effect comprises raw materials including, by weight, 90-110 parts of deionized water, 41-56 parts of 2-ethylhexyl acrylate, 32-45 parts of butyl acrylate, 9.4-12.6 parts of styrene, 8.6-12.4 parts of methyl methacrylate, 0.3-1.6 parts of crylic acid, 0.6-1.9 parts of methacrylic acid, 0.3-0.6 part of acrylamide, 0-0.65 part of methacrylamide, 0.6-1.3 parts of hydroxyethyl acrylate, 0-1.5 parts of hydroxyethyl methylacrylate, 0.5-5 parts of wax emulsion, 2-6 parts of compound emulsifier and 0.2-4 parts of initiator.

Description

technical field

[0001] The invention relates to an acrylate emulsion and a preparation method thereof, in particular to an exterior wall elastic emulsion with a lotus leaf effect and a preparation method thereof. Background technique

[0002] As the ambient temperature alternates, the concrete exterior walls of buildings expand and contract, creating damaging cracks. Elastic coatings for exterior walls are popular in the market due to their good thermal expansion and contraction properties, which can effectively solve the problem of destructive cracks on the surface of building bases. The main component of the elastic coating for external walls is elastic emulsion, whose glass transition temperature is lower than the ambient temperature, and it is an elastomer at the ambient temperature used. Elastic coatings for exterior walls have good tensile properties due to their good elasticity and soft coating film. However, while the elastic coating for external walls effectively ...
