Abstract

The invention discloses a coating for an external wall of a building. The coating is prepared from the following raw materials in parts by weight: 6-8 parts of nonylphenol polyoxyethylene ether, 4-5 parts of chromium sulfate, 6-8parts of a coating curing agent, 10-12 parts of titanium dioxide, 10-12 parts of gypsum powder, 8-12 parts of epoxy resin, 12-18 parts of acetone, 4-5 parts of sodium hydroxide and 12-18 parts of starch. The coating for the external wall of the building has good adhesiveness, electrical insulating property, heat resistance and corrosion resistance as being prepared from special components.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, in particular to a coating for building exterior walls. 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. The exterior wall paint is also required to have water resistance and self-cleaning properties. The paint film must 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. [0003] The world's coating variety structure is developing in the direction of reducing VOC, and water-based coatings are one of the development directions. The proportion of traditional solvent-based coati...
