Abstract

The present invention discloses a high performance modified styrene butadiene rubber composition. The high performance modified styrene butadiene rubber composition is prepared from the following raw materials: styrene butadiene rubber, epoxidized natural rubber, a carbon nano-tube, modified montmorillonite, nano aluminium nitride, precipitation-method white carbon black, modified boehmite, nano aluminium hydroxide, nano magnesium hydroxide, stearic acid, sulfur, zinc oxide, organic silicon peroxide, polyvinyl alcohol, diphenyl phosphate, lanthanum stearate, an anti-aging agent RD, an anti-aging agent NBC, an anti-aging agent 4010NA, diethyl dithiocarbamate zinc, dithiocarbamate cerium formate glutamate, an accelerant DM and triethyl citrate. wherein a modifier of the modified boehmite is a mixture comprising one or more of methacrylic acid, itaconic acid, sorbic acid, maleic acid, arachidonic acid and linoleic acid. The high-performance modified styrene butadiene rubber composition provided by the present invention has high strength, good abrasion resistance, and excellent heat resistance and weather resistance.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a high-performance modified styrene-butadiene rubber composition. Background technique [0002] Styrene-butadiene rubber, also known as polystyrene butadiene copolymer, has better wear resistance, heat resistance, aging resistance and vulcanization speed than natural rubber. It has been widely used in tires, tapes, hoses, wires and cables, and medical appliances. It is the largest general-purpose synthetic rubber variety and one of the earliest rubber varieties to realize industrial production. With the development of society, people put forward higher requirements for the quantity and quality of rubber products, and because the use environment of rubber products is relatively changeable, the strength, wear resistance and aging resistance of existing rubber products cannot meet the requirements of rapid The demands of the developing society require improvements.
