Problems solved by technology

[0002] Heat-resistant coatings play an irreplaceable role in many fields such as industrial production and daily life. It cannot be ignored that many links in the preparation, coating and curing of traditional heat-resistant coatings cannot meet the requirements of environmental friendliness, high efficiency, Requirements for low energy consumption, such as the toxicity and high emissions of volatile organic compounds in some solvent-based coatings
[0003] At present, the main direction of heat-resistant coating research is green environmental protection and reduction. Chinese patent CN 101024739A discloses a water-based inorganic heat-resistant coating. Its composition (weight percentage) is: kaolin 35-46%, quartz powder 30-35% , ceramic short fiber 4-10%, titanium dioxide 4-8%, iron red 10-15%, the liquid phase is sodium water glass and additives, the additives are 3.5-6.5% of the liquid phase mass, the cured coating is attached Strong force, high hardness and impact strength; the patent CN1751106A applied by DuPont Company of the United States in China relates to a heat-resistant powder coating, the main components of which are polysiloxane resin and low-melting glass particles. The coating can withstand 550 The high temperature above ℃ does not fall off from the substrate. For the above-mentioned environmentally friendly heat-resistant coatings, although the volatile organic compounds in the preparation and coating process of water-based coatings and powder coatings are relatively low, the curing methods of the coatings are both Thermal curing, the coating is cured at a higher temperature in the baking equipment to form a film. This method consumes a lot of energy, and the curing speed of the coating is slow and the production efficiency is low.
[0004] In addition, existing heat-resistant coatings are still prone to problems such as fading, loss of gloss, and increased coefficient of friction at high temperatures
