Abstract

The invention relates to the technical field of tires, and discloses a bicycle tire cord adhesive which is prepared from the following raw materials in parts by weight: 80-100 parts of natural regenerated rubber, 80-100 parts of nitrile rubber, 15-38 parts of active kaolin, 75-88 parts of high reinforcement carbon black, 1-10 parts of a vulcanizing agent, 1-20 parts of a promoting agent, 1-9 parts of zinc oxide, 3-8 parts of arene oil, 0.1-2 parts of stearic acid, 1-10 parts of an anti-aging agent and 1-10 parts of an adhering agent. According to the method, as natural and regenerated rubber and nitrile rubber are used together, and the activated kaolin and the high reinforcement carbon black are added, the adhesive is excellent in durability and tensile strength and good in reinforcement property; the adhesive is excellent in physical mechanical property, small in permanent compression deformation, high in tensile strength, excellent in rebound resilience and excellent in high / low temperature resistance.

Description

technical field [0001] The invention relates to the technical field of tires, in particular to a bicycle tire cord 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 . Since the bias tire is an elastic body composed of various rubber and ot...
