The outsole of cloth rubber shoes is an important part of cloth rubber shoes, which is in direct contact with the ground, and requires the rubber used to have good elasticity, wear resistance, flexural resistance, slip resistance, puncture resistance, etc., generally using natural rubber, styrene-butadiene rubber, butadiene rubber, etc. as raw materials. The tire rubber powder made of the tread part of the waste tire is crushed by physical or chemical methods, which has the basic performance characteristics of rubber, and can be re-added to the outsole of the cloth rubber shoes, effectively reducing the cost of raw materials.
1. Tire rubber powder production cloth rubber shoes molded outsole vulcanization formula
40 parts of natural rubber, 60 parts of styrene-butadiene rubber, 15 parts of tire reclaimed rubber, 25 parts of tire rubber powder, 5 parts of zinc oxide, 3 parts of stearic acid, 60 parts of carbon black N330, 10 parts of engine oil, 18 parts of coumarone resin, 30 parts of clay, 5 parts of industrial fat, 0.9 parts of accelerator M, 0.7 parts of accelerator D, 1 part of accelerator CZ, 2.2 parts of sulfur, 0.2 parts of salicylic acid; A total of 276 copies.
55 parts of natural rubber, 45 parts of butadiene rubber, 90 parts of tire rubber powder, 5 parts of zinc oxide, 0.5 parts of stearic acid, 1 part of antioxidant SP, 0.5 parts of paraffin, 2 parts of anti-frost agent, 40 parts of silica, 6 parts of naphthenic oil, 5 parts of coumaron resin, 2 parts of silane coupling agent, 0.3 parts of accelerator D, 1.5 parts of accelerator DM, 0.2 parts of accelerator TMTD, 2 parts of sulfur; A total of 256 copies.
2. Tire rubber powder produces vulcanization formula for cotton shoe outsole
20 parts of natural rubber, 40 parts of butadiene rubber, 80 parts of tire reclaimed rubber, 50 parts of tire rubber powder, 5 parts of zinc oxide, 3 parts of stearic acid, 1 part of antioxidant A, 1 part of antioxidant D, 40 parts of carbon black N330, 1.5 parts of paraffin, 8 parts of heavy oil, 1.4 parts of accelerator CZ, 2.1 parts of sulfur, a total of 253 parts.
The use of tire rubber powder in the production of cloth rubber shoes outsole can reduce the amount of raw rubber such as natural rubber or synthetic rubber and reduce the cost of raw rubber raw materials. Tire rubber powder itself has good wear-resistant E4LYY814 performance, and after being mixed into the outsole of cloth rubber shoes, it can significantly improve the wear resistance of the sole and prolong the service life of the shoes; Improve the grip of the sole in a slippery environment and improve walking safety; Enhance the anti-aging performance of the sole, so that the sole is better resistant to aging caused by environmental factors such as ultraviolet rays and oxidation.
