Bicycle pedal skins made of rubber have good abrasion resistance, elasticity and slip resistance, combining durability, comfort and functionality, making them an ideal choice among bicycle accessories. Tire reclaimed rubber has the basic performance characteristics of rubber, the price is much lower than natural rubber, synthetic rubber, can be used alone or with natural rubber, synthetic rubber to produce bicycle pedal leather, effectively reduce the cost of raw materials.
1. Natural rubber/tire reclaimed rubber and vulcanized formula for the production of bicycle pedal skin
25 parts of natural rubber, 75 parts of tire reclaimed rubber, 3 parts of zinc oxide, 1.5 parts of stearic acid, 0.6 parts of antioxidant A, 0.6 parts of antioxidant D, 1.8 parts of paraffin, 3.5 parts of carbon black N330, 6.5 parts of carbon black N660, 16 parts of light calcium, 6.5 parts of heavy oil, 0.5 parts of accelerator M, 0.35 parts of accelerator DM, 0.25 parts of accelerator D, 1.9 parts of sulfur; Total: 143 copies.
2. Styrene-butadiene rubber/tire reclaimed rubber and vulcanized formula for the production of bicycle pedal skin
10 parts of styrene-butadiene rubber, 90 parts of tire reclaimed rubber, 1 part of zinc oxide, 0.25 parts of stearic acid, 0.5 parts of antioxidant D, 1.5 parts of paraffin, 80 parts of clay, 14 parts of heavy calcium carbonate, 12 parts of petroleum asphalt, 7 parts of coal tar, 0.36 parts of accelerator DM, 0.12 parts of accelerator ZDC, 2 parts of sulfur; total: 218.73 shares.
3. Natural rubber/tire reclaimed rubber/tire rubber powder and vulcanized formula for the production of bicycle pedal skin
30 parts of natural rubber, 70 parts of tire reclaimed rubber, 40 parts of tire rubber powder, 3.2 parts of zinc oxide, 1.9 parts of stearic acid, 0.6 parts of antioxidant D, 0.6 parts of paraffin, 20 parts of carbon black N330, 19 parts of light calcium carbonate, 10 parts of heavy oil, 0.75 parts of accelerator M, 0.35 parts, 2 parts of sulfur; Total: 198.4 shares.
When a large number of tire reclaimed rubber is used to produce bicycle pedal leather of different hardness, it can be achieved by adjusting the ratio of reclaimed rubber to original rubber, the amount of carbon black, and the amount of plasticizer; The right amount of tire rubber powder can be filled with E4LYY42 can further reduce production costs. When using reclaimed rubber/original rubber together to produce bicycle pedal leather, it is necessary to ensure that all components are evenly dispersed in the rubber, and strictly control the vulcanization time and vulcanization temperature to avoid product quality problems caused by uneven mixing, excessive sulfur or lack of sulfur.
