Embodiment 1
[0021] Example 1 The high-temperature and wear-resistant coating of the present invention was prepared by using the following mass ratio raw materials: 10% polymethylphenyl silicone resin, 20% polyethyl silicone resin, functional filler (talc powder, the particle size of which is 500 mesh ) 20%, white corundum micropowder 20%, fluorocarbon 10%, film former (propylene glycol methyl ether acetate) 3%, dispersant (organosilicon modified polyether amide polymer) 4%, defoamer (poly Siloxane solution) 3%, thickener (fumed silica) 0.8%, demineralized water balance; prepared by the following steps:
[0022] (1) Measure each raw material according to the above mass ratio, add demineralized water, polymethylphenyl silicone resin, and polyethyl silicone resin into the ball mill, and conduct the first ball mill at a speed of 200r / min to obtain a pulp material;
[0023] (2) Use a sprayer to spray fluorocarbon and dispersant into the slurry after the first ball milling at a speed of 1 L / mi...
