A kind of environment-friendly high-elastic pure acrylic exterior wall paint and preparation method thereof

Abstract

The invention discloses an environment-friendly high-elasticity pure acrylic outer wall paint and a preparation method thereof. The paint comprises the following components in percentage by mass:: 8-12% of water, 40-49% of KT-02 pure acrylic elastic emulsion, 3-8% of ZT-6500 high-grade silicone-acrylic emulsion, 10-16% of rutile titanium white, 5-12% of calcined kaolin, 4-10% of calcite powder, 4-10% of mica powder, 1-5% of high-efficiency film forming assistant JS-PPH (302), 1-3% of 3% hydroxypropyl methylcellulose solution, 0.1-1% of high-power bactericidal preservative 981, 0.1-1% of wetting agent 405, 0.1-0.5% of high-power dispersing agent, 0.1-0.5% of thickener AR-2 and 0.1-0.5% of defoamer OS-5201. The paint has the advantages of durable flexibility, excellent extensibility, excellent resilience, excellent high temperature resistance, excellent weather resistance, high water resistance, high alkali resistance, high acid resistance, high artificial aging resistance, high ultraviolet resistance, high chemical resistance, high hydrophobicity, high pollution resistance and excellent adhesive force.

Description

technical field [0001] The invention belongs to the technical field of coatings, and relates to an architectural coating, more specifically to an environment-friendly high-elastic pure acrylic exterior wall coating and a preparation method thereof, which are mainly used in the field of architectural exterior wall coatings. Background technique [0002] At present, more than 80% of the expansion cracks in the external wall of the building occur in the cold winter. As time goes on, the cracks will gradually increase, which will adversely affect or even harm the building. It may cause corrosion of the steel bars inside the concrete and affect the building. function and service life. In order to prevent the occurrence of expansion cracks on the exterior walls of buildings and solve the problem of expansion cracks on the exterior walls of buildings as soon as possible, the inventors of the present application have found and fully confirmed that KT-02 pure acrylic elastic is used ...
