Problems solved by technology

When the tire is running, the carcass of the tire is easily deformed by strong radial, lateral, and circumferential forces, which will lead to abnormal damage phenomena such as bulging and delamination of the bias tire, which will affect the service life of the tire.

Abstract

The invention relates to the technical field of tires, and discloses a bicycle tire tread rubber which comprises the following raw materials in parts by weight: 80-90 parts of natural rubber, 10-20 parts of cis-1,4-polybutadiene rubber, 15-30 parts of plasticizer, 25-58 parts of silica white, 1-10 parts of vulcanizing agent, 1-20 parts of accelerator, 1-9 parts of zinc oxide, 0.1-2 parts of calcium carbonate, 1-10 parts of reinforcing agent cb, 0.1-2 parts of stearic acid, 2-5 parts of anti-aging agent aw, 2-5 parts of anti-aging agent 4010, 1-2 parts of paraffin and 1-10 parts of silane coupling agent. The bicycle tire tread rubber has the advantages of tear resistance, fatigue resistance, heat resistance, abrasion resistance, aging resistance, small deformability, light weight, favorable water absorptivity, long service life, low compressive heat generation and dynamic heat generation, small permanent deformation, favorable anti-slip property and small rolling resistance, and can well absorb shock load.

Description

technical field [0001] The invention relates to the technical field of tires, in particular to a bicycle tire tread compound. Background technique [0002] At present, many countries advocate the use of bicycles as a means of transportation to reduce pollution and exercise. Especially in recent years, it has become common practice to use bicycles as a means of transportation to carry out fitness activities with cycling to and from get off work. The quality of bicycles is in addition to other parts. The construction of its wheels, inner and outer tires is an important element in determining the quality of a bicycle. When the tire is running, the carcass of the tire is very susceptible to multiple deformations caused by strong radial, lateral, and circumferential forces, which leads to abnormal damage phenomena such as bulging and delamination of the bias tire, which affects the service life of the tire . [0003] Tread rubber is an important part of the tire, which is in dir...
