Abstract

The invention relates to a coating, in particular to a heat-insulation energy-saving building coating. The heat-insulation energy-saving building coating is prepared from the following raw materials in parts by weight: 115 to 165 parts of fluorocarbon resin, 35 to 40 parts of polymethyl methyl acrylic ester, 45 to 65 parts of epoxy resin, 65 to 85 parts of ethylene carbonate, 12 to 18 parts of hollow fiber, 45 to 60 parts of titanium dioxide, 20 to 30 parts of silica flour, 10 to 15 parts of a dispersing agent, 5 to 8 parts of a flatting agent, 3 to 5 parts of a defoamer and 8 to 15 parts of an anti-settling agent. According to the heat-insulation energy-saving building coating provided by the invention, the hollow fiber is firstly pretreated, the reflectivity and the heat insulation performance of the hollow fiber are improved, and moreover, modified polymethyl methyl acrylic ester is introduced, so that the heat resistance of the coating is improved, and the adhesive property with a base material is strengthened.

Description

technical field [0001] The invention relates to a paint, in particular to a heat-insulating and energy-saving architectural paint. Background technique [0002] Reflective heat insulation coatings have dual functions of decoration and heat insulation, and belong to functional coatings. Since reflective heat-insulating coatings can significantly reduce the surface temperature of objects exposed to solar heat radiation, such coatings have rapidly expanded from aerospace industry applications to petrochemical industries, grain storage industries, etc. At present, this type of coating has begun to be widely used in construction projects for reflective heat insulation of roofs and walls. Conventional heat-emitting thermal insulation coatings are mixed with fluorocarbon resins, reflective materials, additives, etc. This kind of coating has low high temperature resistance, resulting in a short service life of the coating. In addition, it is easy to peel off when exposed to high te...
