Description

technical field [0001] The invention relates to the technical field of thermal insulation coatings, in particular to a high-adhesion impact-resistant thermal insulation coating. Background technique [0002] Insulation coating is a kind of coating that realizes heat insulation and heat preservation through low thermal conductivity and high thermal resistance. It integrates microporous structure and reticular fiber structure, and has good tolerance, heat insulation performance and cold insulation performance, and is widely used In metallurgy, chemical industry, transportation and other fields, however, the adhesion of thermal insulation coatings gradually decreases with the increase of use time, which is prone to peeling off, resulting in local temperature differences in products using this coating, which poses a serious threat to safe production. At the same time, Products coated with thermal insulation coatings are also vulnerable to external forces during use, which also r...

[0002] Insulation coating is a kind of coating that realizes heat insulation and heat preservation through low thermal conductivity and high thermal resistance. It integrates microporous structure and reticular fiber structure, and has good tolerance, heat insulation performance and cold insulation performance, and is widely used In metallurgy, chemical industry, transportation and other fields, however, the adhesion of thermal insulation coatings gradually decreases with the increase of use time, which is prone to peeling off, resulting in local temperature differences in products using this coating, which poses a serious threat to safe production. At the same time, Products coated with thermal insulation coatings are also vulnerable to external forces during use, which also requires thermal insulation coatings to have good impact resistance. The existing thermal insulation coatings cannot meet this demand
