Problems solved by technology

Patent CN101205435A discloses a solar heat reflective heat-insulating coating, which is formed by blending two parts of the surface layer and the bottom layer. The coating contains organic solvents and a small amount of plasticizer, which is not conducive to environmental protection when used on a large scale
The professional application of heat-insulating coatings is still immature, and active-cooling professional heat-insulating coatings with excellent heat-insulating performance, such as heat-insulating coatings specially used on metal surfaces such as open-air chemical equipment and oil pipelines, urgently need to be developed and popularized.

Description

technical field [0001] The invention relates to the technical field of heat-insulating coatings, and more specifically relates to a water-based phase-change temperature-regulating heat-insulating coating that is professionally used on various metal surfaces such as oil pipelines, oil storage tanks, and outdoor industrial cooling equipment and other surfaces. its preparation method. Background technique [0002] The sun radiates huge energy to the earth's surface all the time. Objects exposed to the sun's direct rays often cause the surface temperature to rise excessively due to the gradual accumulation of heat, which brings hidden dangers to safe production. In order to reduce the temperature of these objects The surface temperature wastes a lot of energy. Especially for some petrochemical containers, open-air reactors and oil pipelines, high temperature will bring them potential accident hazards and excessive energy waste. In summer (especially in southern China), due to ...
