Problems solved by technology

But the transmission belt has poor softness at low temperature and is easy to wear, so the service life is not long, and its manufacturing process is relatively complicated, and the operation is inconvenient, so the transmission belt and its manufacturing method still need to be further improved

Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] Implement one, such as figure 1 As shown, the basic composition of the transmission belt of this embodiment is as follows: in every 100 parts of EPDM rubber, add 1.5 parts of anti-aging agent, 1.5 parts of polyethylene glycol, 5 parts of phenolic resin, and 4 parts of resorcinol , 50 parts of paraffin oil, 20 parts of carbon black, 5 parts of reinforcing ribs made of aramid fiber, 30 parts of reinforcing agent 6851, 25 parts of industrial cloth, and the above are parts by weight. The anti-aging agent is: 2,2,4-trimethyl-1,2-dihydroquinoline polymer or 2,2,4-trimethyl-1,2-dihydroquinoline polymer or 1, A homopolymer of 2-dihydro-2,2,4-trimethylquinoline or 2,2,4-trimethyl-1,2-dihydroquinoline. The formula includes 1.5-2.5 parts of dispersant WB222, and the above are parts by weight.

[0027] According to above-mentioned formula, the m...

Abstract

The invention discloses a driving belt and a manufacturing method thereof. A formula for the driving belt is that: 1.3 to 1.6 weight parts of anti-aging agent, 1.3 to 1.6 weight parts of polyethylene glycol, 4 to 6 weight parts of phenolic resin, 3.5 to 4.5 weight parts of resorcinol, 49 to 51 weight parts of paraffin oil, 20 to 50 weight parts of carbon black, 5 to 6 weight parts of reinforcing rib made from aramid fibers, 29 to 31 weight parts of reinforcing agent 6851 and 24 to 26 weight parts of industrial cloth are added into every 100 weight parts of ethylene-propylene-diene monomer rubber. The manufacturing method for the driving belt comprises the steps of plastication, forming, vulcanization, cutting, grinding, printing and formation of a finished product. The conventional chloroprene rubber is replaced by the ethylene-propylene-diene monomer rubber, various auxiliaries for different uses are added, and a gum structure compounded by short fibers and a thin tape body process are introduced, so that the formed product has the advantages of high temperature resistance, abrasion resistance, small elongation for use, low noise, high driving efficiency, high flexibility, long service life and the like, has higher ageing resistance, particularly higher ozone aging resistance, higher weather resistance and higher thermal aging resistance, and also has a higher electric insulation property, higher chemical corrosion resistance and higher impact elasticity.

Description

technical field [0001] The invention relates to the technical field of transmission belt production, in particular to an automobile transmission belt and a production method thereof. Background technique [0002] Transmission belts include automobile synchronous belts, V-belts, cut V-belts, flat belts and other rubber transmission belts, which are important parts of the engine, including synchronous belts (timing belts) for timing transmission between the camshaft and the crankshaft And V-belts and V-belts used to drive front-end accessories of engines such as generators, power steering pumps, fans, water pumps, superchargers and air-conditioning compressors. Most of the technical progress of automobile transmission belts is closely related to the technical development of engines. As people's requirements for lightweight engines are getting higher and higher, the width and height of engines are constantly decreasing, but the output power is constantly increasing. This requir...
