Problems solved by technology

However, there are still some problems in silica filler rubber: the strong interaction between silica particles makes processing difficult, difficult to disperse, and incompatibility with polymers commonly used in tread rubber, which affects its use.
But these reported silica dispersants are less effective in improving the dispersion of silica

Abstract

The invention provides a tire tread rubber composition which has good processing performance, packing dispersibility and wearing resistance and has no hysteresis loss increase. The rubber composition is prepared from the following components in parts by weight: 100 parts of rubber, 40-120 parts of silicon dioxide, 0.1-20 parts of amine salt and 1-20 parts of silane coupling agent in 100 parts of silicon dioxide. The invention also relates to an inflatable tire using the rubber composition for preparing the tire tread.

Description

technical field [0001] The invention belongs to the field of rubber compositions, in particular to a tire tread rubber composition and a pneumatic tire using the rubber composition. Background technique [0002] Silica is used as a reinforcing filler for tire tread rubber to improve the traction of tires on wet and snowy roads, and at the same time improve tire rolling resistance, wear and traction performance. It has received extensive attention in the tire industry. However, there are still some problems in silica filler rubber: the strong interaction between silica particles makes processing difficult, it is not easy to disperse, and it is incompatible with commonly used polymers for tread rubber, which affects its use. [0003] The traditional method to improve the dispersion performance of silica is to add additives such as organic acid zinc salt, organic acid potassium salt, or wax, but these additives only improve the processing performance by increasing the plastici...
