[0004] At present, the coating used as the finishing layer in the thermal insulation system for building exterior walls is a coating with ordinary emulsion as the film-forming substance. When the temperature difference between the external environment becomes large, the coating film of the finishing layer will crack, which will cause the thermal insulation layer to be damaged. cracking, which affects the service life of the entire insulation system of the building's outer wall; in addition, these coating films have poor stain resistance, which affects the appearance of the building

Abstract
The invention discloses thermal-insulation and heat-preservation paint and belongs to the technical field of paint. The thermal-insulation and heat-preservation paint includes following components, by weight, 100-150 parts of a nano organic siliconemulsion, 30-50 parts of a styrene-acrylic emulsion, 15-20 parts of a water-soluble saturate polyester resin, 10-15 parts of expanded perlite, 30-45 parts of hollow microspheres, 10-20 parts of a dispersing agent, 4-6 parts of a toughening agent, 4-6 parts of a thickening agent, 1-5 parts of a film forming additive, 30-50 parts of a pigment and 80-100 parts of water. Compared with thermal-insulation and heat-preservation paint in the prior art, the thermal-insulation and heat-preservation paint not only has a good heat-preservation performance after construction, but also is not liable to crack under a work condition of large temperature difference and is strong in an anti-pollution property.
Description
technical field [0001] The invention belongs to the technical field of coatings, in particular to a thermal insulationcoating. Background technique [0002] The thermal insulationcoating combines the dual characteristics of coatings and thermal insulation materials. After drying, it forms a thermal insulation layer with certain strength and elasticity, thus playing the role of thermal insulation. [0003] Building heat insulation materials can achieve the purpose of heat preservation and heat insulation after being compounded with the building envelope. It is a commonly used material in the implementation of building energy conservation. Building thermal insulation coatings are more and more welcomed and favored by users because of their advantages such as economy, ease of use and good thermal insulation effect. [0004] At present, the coating used as the finishing layer in the thermal insulation system for building exterior walls is a coating with ordinary emulsion as t...
