Abstract

The invention discloses an external wall insulation coating. The external wall insulation coating is prepared from the following raw materials in parts by weight: 60 to 70 parts of polyvinyl acetate emulsion, 20 to 30 parts of Portland cement, 10 to 15 parts of acrylate resin, 10 to 15 parts of acrylic acid, 5 to 10 parts of ceramic fiber, 6 to 8 parts of anti-crack fiber, 20 to 30 parts of light calcium carbonate, 5 to 8 parts of sodium carboxymethylcellulose, 3 to 6 parts of sodium dodecyl benzene sulfonate, 1 to 3 parts of lignosulfonic acid, 5 to 8 parts of titanium dioxide, 10 to 15 parts of kieselguhr, 6 to 9 parts of thickener, 1 to 3 parts of flatting agent, 1 to 3 parts of flame retardant and 8 to 15 parts of deionized water. The external wall insulation coating disclosed by the invention is high in adhesiveness property, unlikely to peel off, good in anti-crack performance and weather resistance, free of cracks after the coating is used for a long time, and good in insulation effect and has a waterproof performance.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to an exterior wall thermal insulation coating. Background technique [0002] In addition to the thermal insulation function, the thermal insulation coating can also make the appearance of the building beautiful and tidy. At the same time, it can also protect the wall surface of the building and prolong its service life. Some external wall insulation materials on the market have single functions and poor waterproof performance. After a long time, the insulation coating will crack and fall off easily, and the insulation effect will be significantly reduced. Contents of the invention [0003] The object of the present invention is to provide a thermal insulation coating for exterior walls, which has strong bonding performance, good crack resistance, good weather resistance, good thermal insulation effect and waterproof performance. [0004] The technical solution adopted in the present inve...
