Fire-resistant rubber

The invention belongs to the field of rubber, and particularly relates to a fire-resistant rubber. The fire-resistant rubber comprises the following components in parts by weight: 50-160 parts of neoprene, 60-150 parts of ethylene-propylene-diene rubber, 4-12 parts of nano zinc oxide, 1-5 parts of stearic acid, 10-25 parts of magnesium hydroxide, 2-6 parts of aluminium phosphate, 2-12 parts of magnesium silicate, 2-10 parts of sodium silicate, 4-18 parts of mica powder, 2-12 parts of silicon carbide, 1-5 parts of an antiager, 1-10 parts of calcium carbonate, 1-7 parts of hydroxyl silicone oil, 1-6 parts of hydrosilicone oil, 1-5 parts of white carbon black, 1-5 parts of simethicone, 1-5 parts of dibutlyl phthalate, 1-5 parts of N-tert-butylbenzothiazole-2-sulphenamide and 1-5 parts of 2-imidazolidinethione. The invention has the benefits that the fire-resistant rubber prepared by the formula has good refractability and can play a certain protective role in a big fire to reduce loss caused to people by the big fire.
