Flame retardant rubber

Abstract

The invention relates to a flame retardant rubber. The flame retardant rubber comprises the following raw materials in parts by weight: 50 to 80 parts of chlorosulfonated polyethylene, 30 to 50 parts of polyacrylate rubber, 40 to 70 parts of butyl rubber, 5 to 15 parts of ethylene-vinyl acetate, 1 to 5 parts of age resister, 15 to 30 parts of aluminum hydroxide, 1 to 10 parts of plasticizer, 10 to 20 parts of calcium carbonate, 10 to 15 parts of dibutyl phthalate, and 1 to 5 parts of 2-mercaptan imidazoline. The flame retardant rubber has a good flame retardant effect, and can lower down the concentration of smoke and absorb hydrogen chloride produced during combustion, in order to avoid damage to a human body.

Description

technical field [0001] The invention relates to a flame-retardant rubber. Background technique [0002] Since the main chain of most high polymers such as rubber and plastic contains a large amount of carbon, hydrogen, oxygen and other elements, it is easy to generate combustible gas when heated and melted, and it is easy to burn with oxygen at high temperature. In order to achieve the purpose of flame retardancy, the traditional method is to use halogen-containing polymers and add a large amount of halogen-containing flame retardants. However, once a fire breaks out, a large amount of smoke and toxic corrosive hydrogen halide gas will be produced, causing secondary disasters. The damage is often more serious than the direct consequences of burning, and the secondary damage and aftereffects are more lasting. , and the steel bars in the machine switchgear and reinforced concrete will also be corroded and damaged; secondly, the dense smoke will seriously prevent people from e...
