Electron beam modification method for reducing rolling resistance of tire tread rubber material and improving abrasion resistance

Abstract

The invention relates to an electron beam modification method for reducing rolling resistance of a tire tread rubber material and improving abrasion resistance. The method comprises the steps of placing tire tread vulcanized rubber on a conveyor belt, and conducting irradiation modification on the vulcanized rubber through a scanning window of an electron beam accelerator mounted in an irradiation room. A cross-linking network of a rubber composite is improved, the interaction between the rubber and a filler is improved, the rolling resistance is reduced, and the abrasion resistance is improved. With the simple and effective electron beam irradiation method, the rolling resistance of a tread is reduced, the abrasion resistance is improved, and a novel technological approach is provided for surface modification of a finished tire.

Description

technical field

[0001] The invention relates to the technical field of manufacturing rubber composite materials, in particular to an electron beam modification method for reducing rolling resistance of tire tread rubber materials and improving wear resistance. Background technique

[0002] An ideal tire tread rubber material should have low rolling resistance, high wear resistance and good wet skid resistance, but these three properties interact and restrict each other, and it is difficult to achieve a balanced optimization among the three. The "Devil's Triangle" for tire performance.

[0003] The traditional modification method is to adjust the formula of tread rubber composite materials, such as developing and applying new fillers and designing new rubber raw materials. The method of carbon black filling can give the tread rubber better wear resistance, but often the rolling resistance is high; the filling method of silica modified by the coupling agent can reduce the rol...
