Abstract

The invention discloses a fireproof rubber. The fireproof rubber comprises the following components in parts by weight: 50-60 parts of styrene butadiene rubber, 35-40 parts of fluorubber, 5-8 parts ofzinc oxide, 1-2 parts of hydrogen silicone oil, 1-5 parts of graphite powder, 8-15 parts of magnesium hydroxide, 4-5 parts of expanded vermiculite, 2-3 parts of a vulcanizing agent, 3-10 parts of aluminium phosphate, 3-10 parts of sodium silicate, and 10-11 parts of silicon carbide. The fireproof rubber has good fireproof performance and excellent fluidity, can effectively increase the aging andpressure-resistant property of rubber materials, has good stability, has certain protection effect in fire disaster, and can reduce loss due to fire disaster for people.

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 they are easy to burn in case of fire. This field lacks a 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, h...
