Problems solved by technology

[0002] In many fields such as buildings, roads and mechanical equipment, in order to effectively prevent the impact of heat radiation on buildings and mechanical equipment, it is currently mainly used to cover the surface of buildings or mechanical equipment such as asbestos, ceramic fiber wool, glass fiber wool, etc. And aluminum foil and other structures for heat insulation protection, when such structures often have defects such as complex structure, difficult construction, and insufficient ability to resist external damage to varying degrees, which seriously affects the heat insulation protection ability of buildings and equipment. In addition, the current Such heat insulation protection structures cannot effectively meet the requirements of precision equipment and occasions and equipment such as roads with large usage and wear. In response to this problem, although a variety of resin-based high-molecular polymers have also been developed. Thermal insulation coating materials, such as application number: 201580052163.7 and application number: 201810778056.8, both record this type of coating with heat energy reflection and its production or use technology, but it is found in actual use that the currently used On the one hand, all kinds of coatings with heat insulation ability have relatively poor heat insulation ability to varying degrees. At the same time, they are also prone to damage and cracking due to external force impact, chemical corrosion, high temperature ablation and low temperature freezing during use. And peeling off, etc., resulting in the decline of thermal insulation protection, but also lead to the coating environment is greatly restricted and the coating use and maintenance costs are relatively high defects, on the other hand, currently used with The heat reflective coating also has the disadvantages of relatively large density and self-weight, high transportation, construction cost and labor intensity.
