Abstract

The invention discloses an external wall heat-insulating coating, which comprises the components of a silicone resin emulsion, an organosilicon water repellent, a flexible acrylic emulsion, a dispersant, a wetting agent, a preservative, a thickener, a leveling agent, a defoamer, a pH value regulator, rutile titanium pigment, gap glass microballoons, coarse whiting powder, a film-forming auxiliary agent, ethylene glycol, hydroxyethyl cellulose, deionized water and the like, and is prepared by preparation processes of dissolving and dispersing through a high-speed dispersion kettle, mixing and the like. The external wall heat-insulating coating has the characteristics of low moisture pickup, high permeability, excellent dirt resistance and weathering durability, and obvious heat-insulating effect, and has good compatibility and matching property with an external wall heat-insulation system, is convenient for construction, and is widely applied to brushing and decorating the external walls of buildings.

Description

[0001] Field of invention [0002] The invention relates to the technical field of building materials, in particular to a thermal insulation coating for exterior walls. Background technique [0003] In the building construction industry, exterior wall paint is a kind of building material product used for painting and decoration of building exterior walls, and it is an essential material. Today, when the global heat effect is intensified, energy conservation and emission reduction is a common problem faced by the construction industry in the world. Building energy conservation is an important part of energy conservation and emission reduction. my country has included the issue of building energy conservation in building regulations in the form of legislation. " "Technical Regulations for Construction of Exterior Wall External Insulation System" has been enforced in the construction industry across the country. With the widespread application of external thermal insulation syste...
