Embodiment 1
[0011] During the process trial production in the laboratory, three samples were produced using the modified heat-resistant coating protection process. The pre-treatment is pre-degreasing and degreasing cleaning process, then the surface is cleaned with compressed air, and then the modified epoxy silicone heat-resistant protective coating is sprayed. After 72 hours at room temperature, the thickness of the coating is 15-30 μm according to GB / T 13452.2. between. Carry out heat corrosion resistance test. After keeping the three samples at 300°C for 1 hour, take them out and quench them in pure water for 1 minute. The paint film has no cracking or discoloration. After taking out the samples and adapting to the environment for 30 minutes, conduct a 240-hour salt spray test. The coating has no obvious discoloration and peeling, and the adhesion reaches Grade 1 according to the GB / T 9286-88 test. The impact strength is greater than 392N.cm according to the GB / T 1732 test, and the st...
Embodiment 2
[0013] Apply a heat-resistant protective coating to the off-road vehicle exhaust system with a calibrated load of 6 tons according to the requirements of the patent "A heat-resistant protective coating and coating process applied to off-road vehicle brake discs"; The patented brake disc is painted with general epoxy silicone heat-resistant paint as usual, degreased and cleaned for 3 minutes according to the patent, blown dry with compressed air, sprayed a heat-resistant protective coating after cleaning the surface, and dried the wet paint film for 5 minutes Dry at 60°C for 20 minutes. After 30 minutes of curing, according to GB / T 13452.2, the thickness of the coating is between 18 and 22 μm.
[0014] The above-mentioned brake discs processed with special protective coatings and the exhaust system processed with traditional coatings are installed on two off-road vehicles simultaneously, and road tests are carried out simultaneously. After a mileage of 50,000km, the coating pr...
