Embodiment 1

[0057] The embodiment of the present application provides a tire tread and a tire, and the specific steps are as follows:

[0058] 1. Prepare the first sizing material, the second sizing material and the third sizing material. In parts by weight, the first sizing material comprises: 70 parts of natural rubber, 30 parts of non-oil-extended polystyrene butadiene rubber, 40 parts of carbon black, 10 parts of white carbon black, 2 parts of process oil, 2 parts of solid silane coupling agent, 4.5 parts of tackifying resin, 3 parts of anti-aging agent, 8 parts of active agent, 1.8 parts of accelerator and 3 parts of vulcanizing agent.

[0059] Specifically, non-oil-extended polystyrene-butadiene rubber is a product of Taiwan Rubber Company, the mass content of styrene in non-oil-extended polystyrene-butadiene rubber is 10%, and the mass content of vinyl in butadiene in non-oil-extended polystyrene-butadiene rubber is 40%, the glass transition temperature (DSC) of non-oil-extended st...

Abstract

The invention belongs to the technical field of rubber tires, and particularly relates to a tire tread, a manufacturing method thereof and a tire. The invention provides a tire tread which comprises afirst rubber layer and a second rubber layer, and the second rubber layer is arranged on the upper layer of the first rubber layer; the first rubber layer comprises a first rubber material; the second rubber layer comprises a second rubber material and a third rubber material; the second rubber material is arranged on the two sides of the third rubber material; the second rubber material and thethird rubber material are different rubber materials; the first rubber material, the second rubber material and the third rubber material are different rubber materials; the tire tread can effectivelyovercome the technical defects that an existing common tire tread is single in performance, and the rolling resistance performance and the high wet skid resistance performance are difficult to consider at the same time.

Description

technical field [0001] The present application belongs to the technical field of rubber tires, and in particular relates to a tire tread, a manufacturing method thereof and a tire. Background technique [0002] With the continuous development of society, people's requirements for the convenience of life are getting higher and higher, so the demand for cars is increasing day by day. Among the many performances of automobiles, the performance requirements of tires are also getting higher and higher. Currently, the EU tire labeling law sets requirements for the rolling resistance and wet skid performance of tires at the same time. [0003] Therefore, after the official implementation of the EU tire labeling law, tires with low rolling resistance and high wet skid resistance have become a research hotspot in recent years. [0004] Theoretically speaking, low rolling resistance formulations usually have low hysteresis loss, while high wet skid resistance formulations have relat...
