Abstract

The invention discloses an environmentally-friendly low-themogenesis rubber composite for a high-capacity tyre body and a high-capacity tyre using the same. The rubber composite for the high-capacity tyre body is prepared by using natural rubber, environmentally-friendly styrene rubber 1500E, white carbon black, natural gas semi-reinforcing furnace black N770, condensed aromatics removed environmentally-friendly aromatic oil and the like as raw materials and matching with reasonable proportional design, which ensures that themogenesis of rubber materials is lower so as to improve the continuous operation time of the tyre body and further ensures that the service life of the tyre is prolonged, greatly reduces health risks caused to processors and users during the production and the use andenables the competence of products to be improved.

Description

technical field [0001] The invention relates to a truck tire, in particular to a rubber composition for a carcass of an environment-friendly and low heat generation truck tire and a truck tire using the rubber composition. Background technique [0002] Environmental protection is the focus of our country and the whole world. Chemical pollution not only affects the environment, but also brings different degrees of damage to the body of producers. In recent years, with the continuous strengthening of environmental protection awareness, relevant laws and regulations have been promulgated, and environmental protection laws and regulations on tire compounds have also come out one after another, which has brought new challenges and opportunities to rubber formulators. [0003] There are multiple environmental pollution factors in the existing tire rubber formulations, such as polycyclic aromatic hydrocarbons, which are internationally recognized as carcinogenic chemicals. The co...
