Abstract

The invention relates to a synchronous belt. The synchronous belt is formed by pouring a rubber material and a strong wire rope. The rubber material includes 45-60 parts by weight of hydrogenated nitrile rubber, trans 1,4-polyisoprene 14 ~25 parts, 6~10 parts of polybutylene terephthalate, 4~8 parts of methacryloxysilane, 7~15 parts of microcapsules, 1~4 parts of lubricant, 1~4 parts of curing agent , 1 to 2 parts of anti-aging agent; the strong cord is one of glass fiber, polyester fiber, aramid fiber and carbon fiber. The present invention also relates to the preparation method of the synchronous belt. The microcapsules wrapped with the adhesive are dispersed in the matrix. When microcracks appear in the matrix material, the capsule wall of the urea-formaldehyde resin is ruptured, and the adhesive in the microcapsules flows out of the capsule to pass through the ring. Oxygen and ‑NH2 in the matrix material are cross-linked and cured, so that the synchronous belt achieves self-healing effect; while hydrogenated nitrile rubber, trans 1,4‑polyisoprene and methacryloxysilane The use effectively improves the overall performance of the synchronous belt.

Description

technical field [0001] The invention relates to the technical field of synchronous belts, in particular to a synchronous belt with a self-healing function, and also relates to a preparation method of the synchronous belt. Background technique [0002] The synchronous belt is an endless belt with equally spaced teeth on the inner peripheral surface. When rotating, the power is transmitted through the meshing of the belt teeth and the gear teeth. The synchronous belt combines the advantages of belt drive, chain drive and gear drive, and has the advantages of high transmission efficiency, accurate transmission ratio, large transmission ratio range, stable transmission, small force on the shaft, low noise, and energy saving. [0003] The main body of early synchronous belts was mostly made of polyurethane rubber. Polyurethane rubber has the advantages of general liquid rubber, good wear resistance, simple process, and convenient molding. However, polyurethane rubber has poor hea...
