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.
