Abstract
The invention discloses a novel rubber sealing ring for a capacitor. The novel rubber sealing ring is characterized in that the rubber sealing ring is prepared from the following raw materials: by weight, 75-80 parts of chloroprene rubber (CR121), 12-15 parts of chloropropylene oxide rubber, 20-23 parts of mica powder, 8-10 parts of wollastonite powder, 3-4 parts of polydimethylsiloxane, 5-6 parts of mineral oil, 1-2 parts of sulphur, 1-2 parts of a promoter M, 4-6 parts of zinc oxide, 16-22 parts of titanium dioxide, 1-2 parts of oleamide, 1-2 parts of calcium stearate, 0.5-1 part of octyltin mercaptide, 20-25 parts of nano-clay and 10-12 parts of modified attapulgite. With the addition of the modified bentonite, processing property of the rubber material is improved. By the use of an environmental compounding agent, toxic and side effect of the rubber sealing ring and its environmental pollution are reduced. The rubber sealing ring provided by the invention has advantages of reasonable formula, low cost, good oil resistance and ageing resistance and long service life, and is safe and nontoxic.
