Problems solved by technology

With the improvement of the requirements for the use of synchronous belts, the synchronous belts made of mixed rubber are gradually increasing, but for the synchronous belts used under special conditions, there is still a lack of targeted research, such as a synchronous belt with patent No. CN201510664133.3 and its manufacture Method, the synchronous belt comprises a synchronous belt frame and a synchronous belt film wrapped outside the synchronous belt frame, using hydrogenated nitrile rubber, polyurethane elastomer, polycarbonate, ethylene-vinyl acetate copolymer, polytrimethylene terephthalate , γ-methacryloxypropyltrimethoxysilane, curing agent, anti-aging agent, and lubricant to improve heat resistance, wear resistance and elasticity, but the mixed system used in it lacks microstructure, resulting in subsequent timing belts poor stability; another example is that the patent number is CN201510793728.9 a kind of elastic synchronous belt and its manufacturing method are made of low phenyl silicone rubber, nitrile rubber, polyurethane, chlorosulfonated polyethylene, neoprene and other raw materials, However, it lacks the skeleton support of the synchronous belt, resulting in a faster performance loss of the synchronous belt at extreme high temperatures, so it is extremely necessary to provide a synchronous belt with good stability at high temperatures

Description

technical field [0001] The invention relates to the field of synchronous belt manufacture, in particular to a heat-resistant aramid fiber synchronous belt and a preparation method thereof. Background technique [0002] The synchronous belt is a new type of transmission belt whose working surface is a toothed structure, and the belt teeth are meshed with the gear teeth to transmit power. Synchronous belt drive combines the advantages of chain drive, belt drive and gear drive, and has the characteristics of accurate transmission, low noise, high efficiency, large speed ratio, no pollution, low energy consumption, compact mechanical structure, etc., and has a large transmission power range. [0003] Early synchronous belts were made of cast polyurethane rubber, which has the advantages of general liquid rubber and does not require equipment such as rubber mixing and calendering. The process is simple and easy to form. The centrifugal casting method can produce light conveyor be...
