Embodiment Construction

[0019] The present invention will be further described below in conjunction with embodiments:

[0020] The present invention takes natural rubber as the main component in the formula of shoulder pad rubber, which has good comprehensiveness and good process viscosity. Natural rubber is 10# and 20# standard rubber produced in Thailand.

[0021] LBR-50 liquid butadiene rubber is a new type of polymer material synthesized by new technology. It has wide molecular weight distribution, low glass transition temperature, high viscosity, good viscosity-temperature performance, high low-temperature viscosity, non-drying and long-lasting, and it is mixed with natural rubber Good performance. As a special softener, it can reduce mixing time and extrusion temperature. The teleclaw structure does not affect its physical properties, can reduce the heat generation of the rubber compound and improve the viscosity of the parts.

[0022] The carbon black used in the reinforcement system of the formula ...

Abstract

The invention relates to the technical field of rubber, in particular relates to a tire tread rubber composition. The tire tread rubber composition is characterized by taking 100 parts of natural rubber as reference, also comprising 5-10 parts of LBR-50 liquid butadiene rubber, 40-55 parts of N234 carbon black, 5-15 parts of white carbon black, 2.5-3.0 parts of zinc oxide, 1-3 parts of stearic acid, 1-3 parts of silane coupling agent mixed by triethoxysili tetrasulfide and inertia dispersing agent with a weight ratio of 1:1, 1-3 parts of N-(1, 3-dimethylbutyl)-N'-phenyl-p-phenylenediamine anti-aging agent, 1-2 parts of 2, 2, 4-trimethyl-1, 2-dihydroquinoline polymer anti-aging agent, 1-2 pats of Rhine wax 111 protective wax, 1-1.5 parts of sulphur, 1.0-1.5 parts of N-tert-butyl-2-benzothiazolylsulfenamide vulcanization accelerator, and 0.1-0.3 parts of cyclohexylthiophthalimide anti-scorching agent in part by weight. In the tire tread rubber composition, the tire wear property can be increased, the tire rolling resistance can be lowered, the tire slippery property is improved, and the comprehensiv use property of the tire can be enhanced.

Description

Technical field [0001] The invention relates to the technical field of rubber, in particular to a tire tread rubber composition and a preparation method. Background technique [0002] As we all know, radial truck tires have the advantages of wear resistance, fuel saving and long service life, and their superior performance is increasingly favored by consumers. The tire crown formula of radial truck tires is not only directly related to the wear resistance of the tire, but also related to the puncture resistance, rolling resistance, dry, wet and snow-slip resistance of the icy and snowy roads. It is related to the safety, environmental protection and energy saving of the tire. Also plays a key role. Reasonable matching of wear, wet skid, and rolling resistance can improve the overall performance of the radial truck tire. Existing tire tread rubber abrasion performance, tire rolling resistance performance and tire wet performance are not very satisfactory. Summary of the inventi...
