Abstract

The invention provides a heat-reflective antifouling exterior wall coating comprising the following raw materials in parts by weight: 40-80 parts of chlorinated rubber modified alkyd resin, 20-40 parts of nano-modified silicone resin, 15 to 25 parts of borosilicate hollow glass beads, 4 to 15 parts of a powder additive, 2 to 10 parts of titanium dioxide, 0.5 to 3 parts of a dispersant, 1 to 5 parts of a thickener, 0.2 to 0.8 part of a film forming aid, 0.2-0.8 part of a leveling agent, 0.1-0.4 part of an antifreeze, 0.2-0.5 part of an antifoaming agent, and 0.3-0.8 part of a fire retardant. The exterior wall coating has excellent heat insulation performance, and the borosilicate hollow glass microbeads and the powder additives can effectively hinder the propagation of light of different wavelengths, ensure constant indoor temperature, have excellent anti-fouling performance, ensure the cleanliness of the surface, andimprove the appearance beauty, and the coating has good weather resistance and anti-aging performance and improved service life.

Description

technical field [0001] The invention relates to the technical field of exterior wall coatings, in particular to a heat-reflecting antifouling exterior wall coating. Background technique [0002] Exterior wall paint is used to paint the exterior walls of buildings, so the most important indicator is anti-ultraviolet radiation, which requires long-term exposure without discoloration. Exterior wall coatings also require water resistance and self-cleaning properties. The paint film should be hard and smooth, and the dirt will fall off as soon as it is washed. Exterior wall paint can be used for interior wall painting because it also has water resistance; while interior wall paint does not have anti-sun function, so interior wall paint cannot be used as exterior wall paint. Heat insulation coating: refers to a functional coating developed in recent years with heat insulation, sun protection, energy saving, environmental protection, simple construction, short construction period...
