Abstract

The invention discloses a modified polyacrylonitrile which comprises polyacrylonitrile, a filling agent, a curing agent, an accelerant, a coupling agent, a flexibilizer and a vulcanizing agent, wherein the filling agent is glass fiber, the curing agent is N-aminoethylpiperazine, the accelerant is zinc dimethyldithiocarbamate, the coupling agent is methacryloxy propyl trimethoxyl silane, the flexibilizer is an acrylonitrile-butadiene-styrene copolymer, and the vulcanizing agent is benzoyl peroxide. According to the modified polyacrylonitrile, the filling agent, the curing agent, the accelerant, the coupling agent, the flexibilizer and the vulcanizing agent are added into the polyacrylonitrile, so that the modified polyacrylonitrile has the characteristics of being high in strength, high in abrasion resistance, excellent in tear resistance, and good in fatigue resistance.

Description

technical field [0001] The invention relates to the field of plastic products, in particular to a modified polyacrylonitrile. Background technique [0002] Polyacrylonitrile is obtained by free radical polymerization of monomer acrylonitrile. The appearance of polyacrylonitrile is white or slightly yellow opaque powder; the relative density is 1.12, and the glass transition temperature is about 90°C. It is soluble in polar organic solvents such as dimethylformamide, dimethyl sulfoxide, sulfolane, and ethylene nitrate, and also soluble in inorganic salts such as thiocyanate, perchlorate, zinc chloride, and lithium bromide. Concentrated aqueous solution, and special solvents such as concentrated nitric acid. The acrylonitrile units in the macromolecular chain are linked by linker-tail. It is mainly used to make polyacrylonitrile fiber. The resulting polyacrylonitrile fiber (commonly known as acrylic fiber) is not high in strength, and has poor wear resistance and fatigue r...
