Abstract

The invention relates to a textile heat-insulating coating, and a preparation method and a using method thereof. The textile heat-insulating coating mainly comprises, by weight percent, 20-35% of film-forming base material, namely polydimethylsiloxane, 10-25% of heat-insulating functional filling, namely rutile titanium oxide, 60-80% of N, N-dimethylformamide, and 1-2% of sodium hexametaphosphate. Compared with the prior art, the textile heat-insulating coating has the advantages that the raw materials are environment-friendly, easy to obtain and low in cost, processing technology is simple, and the heat-insulating coating is high in adhesion, high in weatherability and excellent in heat insulation.

Description

technical field [0001] The invention relates to the technical field of thermal insulation materials, in particular to a textile thermal insulation coating and a preparation method and application method thereof. Background technique [0002] Objects irradiated by the sun, due to the continuous accumulation of heat, the surface temperature and internal temperature of the object will continue to rise, which not only brings great inconvenience and harm to people's production and daily life, but also shortens the industrial process. The service life of instruments and equipment, automobiles, etc. The increase in the surface temperature of building roofs and exterior walls will cause the surrounding environment and indoor temperature to be too high, which will easily form the heat island effect. In many cities in the world, the summer heat island phenomenon is becoming more and more serious, people's living environment is deteriorating, the comfort of the living environment is g...
