Abstract
The invention discloses a wear-resisting tire. The wear-resisting tire is prepared from, by weight, 16-18 parts of natural rubber, 15-18 parts of EPDM rubber, 10-15 parts of isoprene rubber, 1-3 parts of butadiene rubber, 5-10 parts of butadiene styrene rubber, 3-5 parts of nano-silica, 1-3 parts of nano-zirconia, 1-3 parts of polyether polyol, 2-5 parts of dibutyl phthalate, 1-3 parts of 2-ethylhexyl epoxystearate, 3-6 parts of zinc oxide, 2-5 parts of zinc borate, 3-6 parts of stearic acid, 2-5 parts of fortifier and 0.5-1 part of alkoxy type titanate coupling agent. The wear-resisting tire has high bearing performance, traction performance and buffer performance, and has high wear resistance and surrendering resistance and low rolling resistance and heat generation.
Description
technical field [0001] The invention belongs to the field of auto parts, and in particular relates to a wear-resistant tire. Background technique [0002] Tires are ground-rolling circular elastic rubber products assembled on various vehicles or machinery. They are usually installed on metal rims, which can support the body, buffer external impacts, realize contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions. They are subjected to various deformations, loads, forces, and high and low temperature effects during driving. Therefore, they must have high load-carrying performance, traction performance, and cushioning performance. Abrasion and flex resistance, as well as low rolling resistance and heat generation. At present, most of the domestically produced tires cannot meet the above requirements. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present in...
