Embodiment 1
[0021] Example 1 The wear-resistant and high-temperature-resistant coating of the present invention was prepared by using the following mass ratio raw materials: silicone resin base material (polymethyl silicone resin and polyaryl silicone resin, the weight ratio is 3:1) 30%, functional Filler (talcum powder, the particle size is 500 mesh) 20%, white corundum micropowder 20%, fluorinated carbon 10%, film forming agent (propylene glycol methyl ether acetate) 3%, dispersant (organic silicon modified polyether amide polymerization substance) 4%, defoamer (polysiloxane 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 and silicone resin base material into the ball mill, and conduct the first ball mill at a speed of 200r / min to obtain a slurry;
[0023] (2) Use a sprayer to spray fluorocarbon and dispersant into the slurry after ...
