RTV anti-contamination flashover coating material and production process thereof. The present invention relates to an RTV anti-pollution flashover coating and a method of preparing the same. the rtv anti-pollution flashover coating is composed of components of the following parts by weight: 100 parts polydimethylsiloxane, a 4 to 10 parts reinforcing filler, a 0.1 to 1 part catalyst, a 1 to 5 parts crosslinking agent, a hydrophobic 3 to 6 parts, a pigment 1 to 2 parts, decabromodiphenyl ether 1 to 2 parts, and toluene 30 to 40 parts. the hydrophobic agent is a mixture of a substance having a structure represented by formula I and any one or more of a low molecular weight silicone oil, dihydroxydiphenyl silane, fluorine-containing silicone oil and white oil. in formula i, r is any one of acetoxy ch 3 coo-, methoxy ch 3 o-, ketoxime methylene-, an amide group acmen-, c 6 h 11 nh-amino and h 2 c=cmeo acetonyl; r1-si is a polysiloxane group or a fluorine-containing siloxane group, and has a structural formula represented by formula ii. in formula ii, n=1 to 4, and r2 is ch3- or cf3 -. |
