The market of shoes, sports shoes, canvas shoes, protective shoes varied, the production of rubber soles of the raw materials also have their own characteristics, rubber soles, Oxford soles, pvc soles. Which use the soles of rubber production flexibility, comfort, loved by many people. Now with the increasing number of rubber sole manufacturers, market competition is getting bigger and bigger, many shoe manufacturers have begun to formulate appropriate tire reclaimed rubber, rubber raw materials to reduce costs and seek greater profits. Rubber soles formula to add a reasonable tire reclaimed rubber, not only can reduce the cost of raw materials, but also to improve the processing of rubber soles, rubber soles to improve anti-aging, flex resistance and other properties.
Natural rubber 3, 70 parts; accelerator DM, 1.3 parts; butadiene rubber, 30 parts; accelerator M, 0.7 parts; tire reclaimed rubber, 150 parts; accelerator D, 0.5 parts; Antioxidant A, 1 part; Zinc oxide, 5 parts; Rosin, 0.5 parts; High abrasion furnace black, 20 parts; Paraffin, 1 part; Half reinforcing furnace black, 25 parts; Liquid coumarone, 3 parts; , 20 parts; sulfur, 4 parts; light calcium carbonate, 20 parts; total: 355 parts.
Curing conditions: 0.3 MPa (3 kgf / cm2) × 8 min
The tensile strength of the shoe material produced by using the formula is 11.4MPa (116kgf / cm2), the elongation at break is 435%, the hardness is 68, the relative density is 1.296, the flexing is 430,000 times / E, the wear is 0.67cm3 /1.64km.
Tire recycled rubber raw materials are scrap tires, the main raw material for automobile tires is natural rubber + synthetic rubber + carbon black, so the tire reclaimed rubber and natural rubber and synthetic rubber such as butadiene rubber can be a good blend together; , Low prices,replaceable natural rubber, styrene-butadiene rubber and other high-value rubber not only reduce the cost of raw materials, but also can ease the fluctuations of these rubber raw material manufacturers caused trouble; choose to produce rubber soles reclaimed rubber, it is best to use environmentally friendly Type tire reclaimed rubber, so as to avoid inferior material endanger human health; in order to ensure the rubber sole of the surface gloss and wear resistance, anti-aging properties, the cost allows, then you can use 60-80 between the tire top reclaimed rubber.
