Problems solved by technology

[0003] 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

Abstract

The invention relates to a flame-retardant chloroprene rubber and belongs to the technical field of rubber. The chloroprene rubber disclosed by the invention is prepared from the following raw material constituents in parts by weight: 100 parts of chloroprene rubber, 10-15 parts of natural rubber, 1-5 parts of anti-aging agent RD, 0.2-0.35 parts of thiuram accelerants, 0.4-1 parts of zinc oxide, 5-8 parts of magnesium chloride, 3-6 parts of stearic acid, 45-52 parts of carbon black, 2-4 parts of softening agent, 5-10 parts of antimonous oxide and 3-7 parts of zinc borate. The flame-retardant chloroprene rubber disclosed by the invention has the excellent performances of chloroprene rubber and natural rubber due to a small amount of added natural rubber, thus improving the defects of single rubber; the flame-retardant chloroprene rubber disclosed by the invention is good in comprehensive performances, heat-resistant and flame-retardant due to antimonous oxide and zinc borate which are used as flame retardants.

Description

technical field [0001] The invention belongs to the technical field of rubber, in particular to flame-retardant chloroprene rubber. Background technique [0002] Chloroprene 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, high chemical stability and good water resistance. The disadvantage of chloroprene rubber is that it has poor electrical insulation performance and cold resistance, and the raw rubber is unstable during storage. Neoprene is widely used, such as making conveyor belts and transmission belts, covering materials for wires and cables, making oil-resistant hoses, gaskets, and chemical-res...
