Embodiment Construction

[0020] Below in conjunction with embodiment the present invention will be further described:

[0021] In the invention, natural rubber is the main ingredient in the tire shoulder pad rubber formula, and the natural rubber has better comprehensiveness and better process viscosity. The natural rubber is 10# and 20# standard rubber produced in Thailand.

[0022] 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 viscosity at low temperature, non-drying and long-lasting, and can be mixed with natural rubber. Good performance. As a special softener, it can reduce the mixing time and extrusion temperature. The teleclaw structure does not affect its physical properties, which can reduce the heat generation of the rubber compound and improve the viscosity of the parts.

[0023] The carbon black used in t...

Abstract

The invention relates to the technical field of rubber, in particular relates to a tire tread rubber composition and a preparation method. The tire tread rubber composition is characterized by taking 100 parts of natural rubber as reference, also comprising 5-10 parts of liquid butadiene rubber, 40-55 parts of 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, 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 protective wax, 1-1.5 parts of sulphur, 1.0-1.5 parts of vulcanization accelerator, and 0.1-0.3 parts of 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 comprehensive 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 crown formula of the radial truck tire is not only directly related to the wear resistance of the tire, but also has a relationship with the puncture resistance, rolling resistance, dry, wet and ice-snow road skid resistance, etc. also play a key role. Reasonable matching of wear, wet slip and rolling resistance can improve the comprehensive performance of radial truck tires. The existing tire tread rubber wear performance, tire rolling resistance performance and tire wet skid performance are not very ideal. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies...
