Abstract

The invention relates to the field of thermal insulation and energy saving construction materials, and specifically relates to a thermal insulation finish paint, preparation and applications thereof. The thermal insulation finish paint is composed of the following components in parts by weight: 20 to 40 parts of tert-acetic styrene acrylic emulsion, 40 to 70 parts of finish paint thermal insulation powder, 1 to 10 parts of auxiliary agent, and 10 to 30 parts of water. The thermal insulation finish paint has the advantages of good waterproofness and weatherability. The finish paint can meet the conventional property standards on decoration, weatherability, and the like, and also has a thermal insulation performance, while at the same time the paint coating technology is basically not increased.

Description

technical field [0001] The invention relates to the field of thermal insulation and energy-saving building materials, in particular to a thermal insulation topcoat and its preparation and application. Background technique [0002] In recent years, there have been many varieties of thermal insulation coatings on the market, among which reflective thermal insulation coatings are the main ones. Reflective heat-insulating coatings are composed of base materials, heat-reflecting pigments, fillers and additives. Thermal insulation is achieved by efficiently reflecting sunlight. Thin-layer heat-insulating reflective coatings are representative of this type of coatings. The national reflective heat insulation coating standard (JC / T1040-2007) requires: the solar reflectance is not less than 85%, and the hemispherical emissivity is not less than 83%. [0003] Due to the working principle of reflective paint, in urban construction, the light and energy reflected by reflective paint ...
