Abstract

The invention discloses a fire-resistant rubber, which comprises the following components in parts by weight: 50-60 parts of styrene-butadiene rubber, 35-40 parts of fluororubber, 5-8 parts of zinc oxide, 1-2 parts of hydrogen silicone oil, stearin 2‑5 parts of acid, 8‑15 parts of magnesium hydroxide, 4‑5 parts of expanded vermiculite, 2‑3 parts of vulcanizing agent, 3‑10 parts of aluminum phosphate, 3‑10 parts of sodium silicate, 3‑10 parts of silicon carbide , 1-2 parts of bentonite. The refractory rubber provided by the invention has good fire resistance and excellent fluidity, can effectively improve the aging and pressure resistance of rubber materials, has good stability, can play a certain protective role in a large fire, and can reduce the The loss of people caused by the fire.

Description

technical field [0001] The invention belongs to the field of rubber, and in particular relates to a fire-resistant rubber. Background technique [0002] Usually silicone rubber itself is not fire resistant. However, in the current fire accidents, wires and cables are not fire-resistant and easy to burn in case of fire. This field lacks a kind of fire-resistant silicone rubber, which is required to play a certain protective role in the fire, and can reduce the electricity brought to people in the fire. Loss, reduce the harm of electricity. Refractory rubber is made of chloroprene as the main raw material through homopolymerization or copolymerization of a small amount of other monomers. Such as rubber products with high tensile strength, excellent heat resistance, light resistance, aging resistance, and oil resistance are better than natural rubber, styrene-butadiene rubber, and butadiene rubber. It has strong flame resistance and excellent flame retardancy resistance, hig...
