Problems solved by technology

At present, most of the flame retardant formulations of chloroprene rubber in China usually use halogen-containing flame retardants such as chlorine-containing flame retardants. Although the use of such flame retardants can satisfy a good flame-retardant effect, once a fire occurs, a large amount of toxic Corrosive hydrogen halide gas, causing secondary hazards, the hazards are usually more serious than those caused by combustion, seriously endangering people's lives

Abstract

The invention relates to butadiene styrene rubber. The butadiene styrene rubber comprises the following raw materials in parts by weight: 70 to 80 parts of butadiene styrene rubber, 10 to 20 parts of natural rubber, 3 to 6 parts of polyoxypropylene glycerol ether, 25 to 30 parts of chlorinated paraffin, 10 to 15 parts of white carbon black, 3 to 5 parts of a promoting agent, 5 to 15 parts of an ethylene-propylene polymer, 3 to 5 parts of a vulcanizing agent, 15 to 18 parts of calcium carbonate, 5 to 8 parts of an anti-aging agent and 3 to 5 parts of a plasticizer. The butadiene styrene rubber is good in flame-retardant effect, no toxic gas is produced when in fire, the secondary harm is avoided, and the life security of people is not influenced.

Description

technical field [0001] The invention relates to a styrene-butadiene rubber. Background technique [0002] The elastic force of rubber is entirely produced by the conformational change of coiled molecules. Because the interaction between rubber molecules will hinder the movement of molecular chains, which is manifested as viscosity or viscosity, so that stress and strain are often in an unbalanced state. Part of the force acting on the rubber molecules is used to overcome the viscous resistance between the molecules and absorb part of the energy during the process of viscous friction; the other part deforms the molecular chains, which constitute the viscoelastic properties of rubber. When the rubber is dynamically deformed, due to the viscoelastic viscous resistance, the strain lags behind the stress. This rubber damping property produced by the hysteresis characteristic of rubber and internal friction during deformation is an excellent characteristic of rubber shock absorpt...
