Description

technical field [0001] The invention relates to the technical field of aviation coatings, in particular to a high-temperature-resistant aviation coating and a preparation method thereof. Background technique [0002] High-temperature thermal insulation coating is finished with a special solution. The temperature resistance range is -80°C-1800°C. It can directly face the flame for thermal insulation. The thermal conductivity is only 0.03W / m.K, which can effectively suppress and shield infrared radiation and heat. Heat conduction, heat insulation inhibition efficiency can reach about 90%, can inhibit heat radiation and heat loss of high-temperature objects, insulation, pressure resistance, and reprocessing after curing, just paint directly on the object for a few millimeters. . [0003] Aerospace coatings are coatings used on aircraft. According to the parts used, it can be divided into: aircraft skin coatings, aircraft cabin coatings, aircraft engine coatings, aircraft part...
