The outsole of rubber shoes is in direct contact with the ground and needs to withstand frequent friction, bending, etc. The rubber material is required to be wear-resistant, flexural, elastic, shrink, and adhesive, etc. The black rubber outsole is mostly made of natural rubber and styrene-butadiene rubber. , butadiene rubber processing. The main components of tire reclaimed rubber are natural rubber, synthetic rubber and carbon black. It has good compatibility with natural rubber, styrene-butadiene rubber and cis-butadiene rubber. It can replace the original rubber to produce black rubber outsole and reduce the production cost. The performance requirements of the black rubber outsole in different rubber shoes are different. Today, Xiaobian will share with you some common black rubber outsole vulcanization formulas for the production of tire reclaimed rubber.
1. Original rubber + tire reclaimed rubber to produce black rubber outsole vulcanization formula
(1) Tire reclaimed rubber production Jiefang shoe black outsole vulcanization formula: 50 parts of natural rubber, 15 parts of styrene-butadiene rubber, 35 parts of cis-butadiene rubber, 40 parts of tire reclaimed rubber, 5 parts of zinc oxide, 3 parts of stearic acid, anti-aging 1 part of agent D, 70 parts of carbon black N330, 15 parts of clay, 5 parts of light calcium, 25 parts of motor oil, 2 parts of calcium-based ester, 15 parts of RX 80 resin, 0.7 part of accelerator D, 2 parts of accelerator DM, accelerator M 1.2 parts, sulfur 2.1 parts; total: 287 parts.
(2) Vulcanization formula for black outsole of football shoes produced from tire reclaimed rubber: 10 parts of natural rubber, 90 parts of cis-butadiene rubber, 50 parts of tire reclaimed rubber, 5 parts of zinc oxide, 3 parts of stearic acid, 0.85 parts of anti-aging agent A, anti-aging 0.75 part of agent D, 72 parts of carbon black N330, 15 parts of coumarone resin, 11 parts of motor oil, 0.5 part of accelerator M, 0.5 part of accelerator D, 1 part of accelerator CZ, 2.4 parts of sulfur; total: 262 parts.
(3) Vulcanization formula for black outsole of cotton rubber shoes produced from tire reclaimed rubber: 20 parts of natural rubber, 40 parts of cis-butadiene rubber, 80 parts of tire reclaimed rubber, 5 parts of zinc oxide, 3 parts of stearic acid, 1 part of anti-aging agent A, anti-aging 1 part of agent D, 35 parts of carbon black N330, 58 parts of light calcium, 1.5 parts of paraffin, 12 parts of heavy oil, 1.5 parts of accelerator CZ, 2 parts of sulfur; total: 260 parts.
2. Whole tire reclaimed rubber to produce black rubber outsole vulcanization formula
(1) 100 parts of tire reclaimed rubber, 1 part of zinc oxide, 1 part of stearic acid, 2 parts of antioxidant D, 5 parts of carbon black N330, 48 parts of clay, 0.5 part of accelerator M, 0.5 part of accelerator D, 1.5 part of sulfur servings; total: 159.5 servings.
(2) 100 parts of tire reclaimed rubber, 2.5 parts of zinc oxide, 1.3 parts of stearic acid, 1 part of antioxidant A, 0.5 parts of paraffin wax, 6 parts of carbon black N330, 3 parts of coumarone resin, 2.5 parts of pine tar, accelerator 1.5 part of DM, 0.9 part of accelerator D, 0.2 part of accelerator TMTD, 1.1 part of sulfur; total: 120.5 parts.
In actual production, the reclaimed rubbers commonly used in the outsole of black rubber shoes include tire tread reclaimed rubber, whole tire reclaimed rubber, rubber surface rubber shoe reclaimed rubber and cloth rubber shoe reclaimed rubber. Among them, the tread reclaimed rubber 2ELYY74 has high effective rubber hydrocarbon content and can be The mixing ratio is relatively high, and the physical and mechanical properties of the black outsole are better. Generally, the amount of reclaimed rubber in the rubber shoe outsole with a rubber content among 30-35% can be increased to more than 60 parts, or even completely reclaimed rubber. And adjust the formula appropriately according to the amount of rubber hydrocarbon. In the later period, the editor will continue to discuss with you the specific dosage adjustment method of the vulcanizing agent, accelerator, zinc oxide and other compounding agents in the tire reclaimed rubber sole vulcanization formula.
