Abstract
The invention provides rubber for manufacturing a sealing ring. The rubber is prepared from, by weight, 35%-55% of natural rubber, 20%-25% of chemigum, 5%-8%of mica, 1.5%-2.5% of zinc oxide, 3%-5% of high-wear-resistant carbon black, 2%-5% of kieselguhr, 2%-4% of china clay, 0.8%-1.5% of calcined clay, 1%-2% of chalk, 0.5%-1% of microcrystalline wax, 0.5%-1% of coumarone resin, 0.5%-1% of carnauba wax, 1%-2% of magnesium oxide, 0.5%-1% of stearic acid, 0.5%-1% of cashew nut shell oil, 1%-3% of zinc borate, 2%-5% of oxalic acid, 2%-3% of tributyl citrate, 1%-5% of engine oil, 0.8%-1.2% of accelerant M, 0.5%-1% of accelerant DM, 0.5%-1% of softener TP95, 0.3%-0.5% of accelerant TMTD, 0.5%-1% of antiager RD, 0.1%-0.2% of antiager NBC and 2%-5% of carbon black 550. The rubber for manufacturing the sealing ring is resistant to wear, durable in use, resistant to high temperature and low temperature, excellent in performance, high in tensible strength, simple in preparation method and low in production cost.
