Abstract

The invention discloses antirust high-temperature-resistant paint for aeronautical materials and a preparation method of the antirust high-temperature-resistant paint. The antirust high-temperature-resistant paint is prepared from coal tar pitch, zinc yellow, silver paste powder, paratoluensulfonyl chloride, zinc carbonate, titanium dioxide, polystyrene resin, zinc phosphate, glass powder, melamine, diphenyl ether resin, cyclohexanone, potassium dichromate and a drier. A product is in level 1 of adhesion, free of cracking and shedding at a high temperature, quick in drying and 30-70d in salt fog resistance and can be dried only by drying for 80-120min at 200 DEG C; pendulum hardness is 8-10, coating brightness, smoothness and great thermal strength and dielectric properties are realized, and fineness is 20-40micron; shedding is avoided at a high temperature of 1000-1400 DEG C, metal corrosion is avoided, and flexibility is 0.5-2.5mm; coating film firmness is achieved, steel materials are protected from oxidization and decarbonization, and the paint is resistant to water, acids, alkalis and low temperature and unchanged after being soaked in hydrochloric acid, sodium hydroxide and sodium chloride for 4-8 months.

Description

technical field [0001] The invention relates to the technical field of aviation coatings, in particular to an antirust and high temperature resistant coating for aviation materials and a preparation method thereof. Background technique [0002] In the process of aviation manufacturing development, the replacement of materials presents a high-speed change, and materials and aircraft have been constantly developing under the mutual promotion. "One generation of materials, one generation of aircraft" is a true portrayal of the history of world aviation development. [0003] From 1965 to 1975, at this stage, synthetic resins were mainly used, and the representative paint was acrylic resin paint. This type of coating is characterized by one-component, fast drying, convenient construction, good photothermal stability of the coating, and relatively stable performance, but poor resistance to oil and chemical media; in the early 1980s, research on curing type paint. Because this t...
