Problems solved by technology

[0002] In the past, this type of paste paint, expanded perlite as a heat-insulating paint, can only slow down and cannot block the transfer of heat energy. During the day, the sun passes through the roof and walls coated with heat-insulating paint into the indoor space and structure. After the outside air temperature drops, the heat transfers back to the outside through the roof and walls coated with thermal insulation paint, and the speed of heat transfer is also very slow.

Abstract

The invention discloses a sunlight-heat-reflecting flexible thermal insulation paint which is prepared from 80-100 parts of deionized water, 0.4-0.6 part of ammonia water, 1.3-1.7 parts of mold preventive, 180-220 parts of hollow glass microsphere, 8-12 parts of ethylene glycol, 18-22 parts of titanium white, 1.8-2.2 parts of defoaming agent, 140-180 parts of functional filler, 4-6 parts of alcohol ester-12, 400-600 parts of special-type acrylic flexible emulsion, 4-6 parts of anionic dispersant, 4-6 parts of alkali-activated thickening agent and 0.8-1.2 parts of humectant. The paint disclosed by the invention effectively prevents the temperature rise of the building due to the absorption of solar radiation, and solves the problems of cracking water seepage and quick coating aging caused by the external wall thermal insulation system.

Description

technical field [0001] The invention relates to a paint, in particular to a solar heat reflection type flexible heat insulating paint and a preparation method thereof. Background technique [0002] In the past, this type of paste paint, expanded perlite as a heat-insulating paint, can only slow down and cannot block the transfer of heat energy. During the day, the sun passes through the roof and walls coated with heat-insulating paint into the indoor space and structure. After the outside air temperature drops, the heat transfers back to the outside through the roof and walls coated with thermal insulation paint, and the speed of heat transfer is also very slow. [0003] Solar heat reflective flexible thermal insulation coatings can reduce the absorption of solar radiation by buildings and reduce the introduction of heat into the room. In recent years, the emergence of new high-efficiency reflective glass hollow microspheres has promoted this type of coating. In addition to...
