Tread reclaimed rubber is the highest rubber content in tire reclaimed rubber products with the best elasticity and best wear resistance. It can be used to produce rubber sole to ensure good elasticity and abrasion resistance and has a long service life. The use of tire reclaimed rubber production of rubber soles, according to the performance requirements of rubber soles choose to use the tire reclaimed rubber or with other types of rubber and use, to ensure that the rubber soles to meet the needs of the premise to maximize the amount of tread reclaimed rubber, the maximum Reduce raw material costs.
The use of tread rubber in rubber soles not only reduces the cost of raw materials, but also can improve the rubber soles of the production process and improve the wear resistance of rubber soles, but once in the rubber soles recipes mixed with reclaimed rubber, you need the basis of the original formula On the appropriate adjustments: Generally mixed with the tread rubber reclaimed rubber soles formula appropriate amount of sulfur should be appropriately reduced in 1.7-2.0 or so (this is because the raw material of tread reclaimed rubber - waste tire tread In itself contains a certain amount of vulcanizing agent in the production process has not been completely separated out); reinforcement system can be used with HAF and SRF, activated clay or nano-light calcium carbonate filled, reinforcing agent and reinforcing filler material To control between 50-60 copies, can significantly improve the rubber sole of its own tear resistance and flex resistance performance, reduce production costs.
Xiao Bian and we share a high standard of rubber sole formula.
Natural rubber: 85; Butadiene rubber: 15; Tread reclaimed rubber: 10; Sulfur: 4.4; Accelerator M: 1.3; Accelerator DM: 0.6; Accelerator D: 0.95; Zinc oxide: 4; Stearic acid: 2 ; High wear-resistant carbon black: 45; Light calcium carbonate: 54; Clay: 60; Industrial fat: 2.5; Oil: 15; Scorch retarder: 0.25;
The reclaimed rubber in the formula is used in a small amount to ensure the amount of rubber in the rubber sole and the comfort of the sole, while a small amount of tread reclaimed rubber can not only reduce the raw material cost but also improve the processing performance of the rubber compound Rubber soles physical properties of the role; if you want to reduce the cost of raw materials on this basis, you can increase the amount of tread reclaimed rubber or filler materials (calcium carbonate, clay, etc.) dosage.
The use of reclaimed rubber production of rubber soles, the best choice with the rubber soles closest indicators of the reclaimed rubber products; on the amount of tread reclaimed rubber, rubber products manufacturers from the reality, according to the performance requirements of rubber soles through Multiple tests to determine the optimum amount of recycled rubber dosage; for some sports soles and so on the higher flexibility and comfort of the rubber soles can take the above formula; if it is a low-grade ordinary rubber sole, the full use of tread reclaimed rubber can be.
