[0035] In addition, the present invention also discloses a preparation method of an improved antifouling flashover coating, comprising the following steps:
[0036] 1) According to the formulation requirements of the above-mentioned improved anti-pollution flashover coating, configure the mixed solvent;
[0037] 2) Add the formula amount of hydroxyl-terminated polydimethylsiloxane into the kneader, stir evenly at a speed of 40-60rpm, then add white carbon black, aluminum hydroxide, alumina microspheres, decabromodiphenyl For ether and pigments, adjust the rotation speed to 80-120rpm; after heating to 80-120°C, turn on the vacuum to remove air bubbles and small molecular substances, and maintain the rotation speed at 80-120rpm for 1.5-2h to make the materials in the kneader evenly mixed;
[0038] 3) After the material obtained in step 2) is cooled to room temperature, it is transferred to a three-roll machine for grinding until the grinding fineness of the material is below 20 ...
