[0036]

[0037]

[0038] The preparation method of above-mentioned synchronous belt comprises the following steps:

[0039] (1) Preparation of adhesive:

[0040] (a) Add 1.1moL epichlorohydrin into a three-necked flask equipped with a constant pressure dropping funnel and a reflux condenser, immerse in an ice-water bath, start stirring, and control the temperature within 0-5°C. After stirring for 10 minutes, Start to add 0.5 mol of diglycolamine slowly. After the addition, control the temperature at 0-5°C to continue the reaction for 2 hours, and then react at room temperature for 4 hours. After the reaction, remove excess epichlorohydrin by vacuum distillation; add 300 mL of ethanol Use as a solvent, then add 25% sodium hydroxide solution dropwise at a constant speed, and finish adding dropwise for 15 minutes, then keep the tempe...

Abstract

The invention relates to a synchronous belt. The synchronous belt is formed by casting a rubber compound and strong thread rope, and the rubber compound comprises, by weight, 45-60 parts of hydrogenated nitrile butadiene rubber, 14-25 parts of trans-1,4-polyisoprene, 6-10 parts of polybutylene telephthalate, 4-8 parts of methacryloxy silane, 7-15 parts of a microcapsule, 1-4 parts of a lubricant, 1-4 parts of a curing agent and 1-2 parts of an antioxidant; and the strong thread rope is one of glass fibers, polyester fibers, aramid fibers and carbon fibers. The invention also relates to a production of the synchronous belt. The adhesive wrapping microcapsule is dispersed in a matrix, and when the matrix micro-cracks, the wall of the polyurea resin capsule is ruptured, so the adhesive in the microcapsule flows out of the capsule, and realizes cross-linking curing of an epoxy group with -NH2 in the matrix in order to realize a self-healing effect of the synchronous belt; and hydrogenated nitrile butadiene rubber, trans-1,4-polyisoprene and methacryloxy silane are used to effectively improve the integral performances 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...
