Embodiment 1

[0033] Production method of thermal insulation coating:

[0034] Weigh the following components according to weight fraction: 170 parts of organic hollow microspheres, 100 parts of aluminum silicate, 115 parts of silica lime, 3 parts of thickener, 1 part of defoamer, 4 parts of dispersant, 30 parts of ethylene glycol , 4 parts of polyoxypropylene wetting agent, 500 parts of pure acrylic emulsion, 120 parts of water. The paint also contains 5 parts of triethylamine pH regulator and 2 parts of preservative. Add water, thickener, defoamer, dispersant, ethylene glycol, sodium hydroxide pH regulator and preservative to the mixer, and stir until uniform at 1350rpm; add pure acrylic emulsion, and stir at 1850rpm until uniform; Add organic hollow microspheres, aluminum silicate and wollastonite, stir at 780rpm until uniform; sieve through a 165-mesh sieve.

[0035] After testing, its tensile strength is greater than 1MPa, its solar reflectance is greater than 0.8, and its thermal co...

Abstract

The invention relates to a heat insulation coating and a production process thereof. Raw materials for the heat insulation coating comprise, by weight, 80 to 200 parts of organic hollow microspheres, 50 to 125 parts of alumina silicate, 50 to 135 parts of siliceous lime, 2 to 6 parts of a thickening agent, 1 part to 10 parts of an antifoaming agent, 1 part to 10 parts of a dispersant, 8 to 35 parts of glycol, 3 to 10 parts of a wetting agent, 180 to 500 parts of latex paint emulsion and 100 to 350 parts of water. The heat insulation coating provided in the invention is composed of the organic hollow microspheres suspended in inert latex; microstructure of the microspheres is favorable for reflection and scattering of infrared ray, and the microspheres are enclosed hollow balls, having a low coefficient of heat conductivity; the addition of the microspheres into the coating enables considerable microscopic independent heat insulation cavities to be formed, thereby substantially improving heat insulation of a film.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a heat-insulating coating for building surfaces and a production process thereof. Background technique [0002] At present, the existing building wall insulation coatings in my country are usually based on increasing the gas phase void ratio, reducing the thermal conductivity and conducting heat transfer, such as fiber insulation materials and profile insulation materials. Profile-type inorganic thermal insulation materials need to be assembled and constructed, and have disadvantages such as many seams, affecting the appearance, poor waterproof performance, and short service life. Coating, and the heat insulation effect is not good. Contents of the invention [0003] The invention designs a heat-insulating paint and a production process thereof, and aims to provide a paint with high-efficiency heat-insulating function and is environmentally friendly and pollution-free. [0004] In ord...
