Natural rubber / styrene-butadiene rubber / reclaimed rubber to produce rubber outsole and formula

Natural rubber has good elasticity and high mechanical strength. The wear resistance, heat resistance and aging resistance of styrene-butadiene rubber are better than natural rubber. The raw materials of recycled rubber are widely used and the price of the product is low. The rubber sole can be used to ensure the rubber outsole. Good performance and longevity also reduce raw material costs. Not much nonsense, Xiaobian today shares with you a few natural rubber / styrene-butadiene rubber / reclaimed rubber and the application of the rubber outsole.

Formulation 1: natural rubber, 72 parts; styrene-butadiene rubber, 28 parts; reclaimed rubber, 40 parts; zinc oxide, 4 parts; stearic acid, 2.5 parts; antioxidant A, 0.6 parts; anti-aging agent, 0.6 parts; Black, 60 parts; light calcium, 18.6 parts; petroleum resin, 17 parts; calcium base fat, 5 parts; motor oil, 14 parts; accelerator D, 2.2 parts; accelerator M, 0.8 parts; accelerator DM, 0.8 parts; Sulfur, 2.2 parts. (Gum glue content: 37.2%)

Formula 2: natural rubber, 70 parts; styrene-butadiene rubber, 30 parts; reclaimed rubber, 10 parts; zinc oxide, 5 parts; stearic acid, 3 parts; anti-aging agent, 0.5 parts; carbon black, 74 parts; Long, 10 parts; spindle oil, 15 parts; third-line oil, 13 parts; accelerator CZ, 1 part; accelerator D, 1 part; accelerator M, 1.3 parts; sulfur, 2.2 parts.

(green rubber content: 35%)

Formulation 4: natural rubber, 40 parts; styrene-butadiene rubber, 40 parts; oil-filled styrene-butadiene rubber, 20 parts; reclaimed rubber, 50 parts; zinc oxide, 4 parts; stearic acid, 2 parts; carbon black, 60 parts; Clay, 40 parts; calcium base fat, 15 parts; petrolatum, 4 parts; motor oil, 5 parts; pine tar, 5 parts; coumarone, 10 parts; accelerator D, 0.8 parts; accelerator DM, 2 parts; Agent M, 3.3 parts; sulfur, 1.8 parts. (green rubber content: 33%)

Different types of rubber outsole have different performance requirements, so the content of reclaimed rubber is different. Rubber product manufacturers can use the above formula as a reference to find the most suitable formula for their own products.
