Embodiment 1
[0015] The proportioning by weight of each component raw material of the high temperature resistant paint film of the present invention can be: 12 parts of aluminum oxide micropowder, 5 parts of dititanium nitride micropowder, 8 parts of calcium hexaboride micropowder, 10 parts of chromium trioxide micropowder, 2 parts of graphite, 15 parts of asphalt, 30 parts of gasoline.
[0016] The preparation method of the high-temperature-resistant paint film for diamond vacuum reduction sintering baskets is as follows: first place large pieces of asphalt in a pulverizer, and grind it into small granular asphalt for later use; , in a stainless steel container with h=200, and put the container into a water bath with a water temperature of 80°C for indirect heating to ensure uniform heating. Stir in one direction until the small granular asphalt is completely dissolved, then add graphite according to the stated ratio, stir for 2 minutes, and finally take Al2O3 micropowder, dititanium nitr...
