Abstract

The invention provides a thermal insulation coating applied to a building wall. The thermal insulation coating is prepared from the following raw materials in parts by weight: 40-45 parts of acrylic base polymer, 20-25 parts of cross-linked polymer microspheres, 30-40 parts of filler and 2-4 parts of an auxiliary agent. The particle size D of the cross-linked polymer microspheres is more than or equal to 200nm and less than or equal to 20[mu]m. The functional filler is a barrier type filler. The auxiliary agent comprises one or more of a surfactant, a biocide, a dispersing agent, a defoaming agent and a coalescing agent. The coating has the decoration and protection functions of a traditional exterior wall coating, meanwhile, heat dissipation in a building is blocked through the coating, the heat dissipation speed is reduced, a relative heat preservation effect is achieved, the construction method is simple and convenient, and the heat insulation effect is reliable.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a thermal insulation coating applied to building walls. Background technique [0002] At present, the external wall insulation mainly adopts the methods of pasting insulation boards on the external wall and painting paint. The coating of building exterior decoration materials is the first choice. The external wall thermal insulation coating can not only solve the problem of thermal insulation, but also relatively reduce the thickness of the wall. Therefore, the thermal insulation coating for exterior walls has a broad market prospect, but the existing thermal insulation coating generally has the problem that the thermal insulation effect is not obvious. Contents of the invention [0003] The invention provides a thermal insulation coating applied to building walls to at least solve the problem that the thermal insulation effect of the thermal insulation coating in the prior art is not o...
