Tire recycled rubber is a plastic and viscous rubber that can be re-vulcanized by crushing, desulfurization, refining and other processes made of waste tires as raw materials, with low price, good compatibility with natural rubber and styrene-butadiene rubber, and can be recycled into tire processing. At present, the tire manufacturing industry is facing multiple challenges such as rising raw material costs and stricter environmental protection, and the rational use of tire recycled rubber can effectively reduce production costs under the premise of ensuring tire performance indicators.
Tire manufacturing industry is the largest application field of tire recycled rubber, which can be widely used in tire processing, such as load tires, car tire treads, sidewalls, inner tubes, pads, etc.
1. Application of tire recycled rubber in load-bearing tire tread adhesive
Load-duty tire tread adhesive has extremely high requirements for wear resistance, tear resistance, cutting resistance, aging resistance, etc., and is generally processed with natural rubber/styrene-butadiene rubber/butadiene rubber and glue as raw materials; When using tire recycled rubber E5LYY99 reduce costs, choose high-strength tire tread recycled rubber or ultra-fine tire recycled rubber, control the dosage at 5%-20%, adjust the dosage according to actual demand, and reduce more raw material costs under the premise of ensuring good performance of load-duty tire tread adhesive.
2. Application of tire recycled rubber in car tire tread adhesive
Compared with the tread adhesive of heavy tires, car tires have extremely high requirements for high-speed stability, safety, comfort and rolling resistance, and it is recommended to use 80-mesh ultra-fine tire top recycled glue, and the proportion of recycled rubber is controlled at 5%-15%, so as to improve the performance of the rubber processing process and reduce the cost of raw materials.
3. Application of tire recycling rubber in tire sidewall rubber and cushion tape adhesive
(1) Tire sidewall adhesive: it needs to withstand frequent flexing and deformation during use, and has high requirements for fatigue resistance, flex crack resistance and flex crack resistance of the compound, so it is recommended to choose tire recycled rubber with high fineness and moderate Mooney viscosity, and the mixing ratio is controlled at 10%-30%.
(2) Tire pad tape adhesive: the main function is to protect the inner tube from rim wear, the performance requirements are relatively low, and a large amount of tire recycling rubber can be mixed, and the mixing ratio can reach 30%-50%.
4. Application of tire recycling rubber in tire inner tube
Tire inner tube is a key component to maintain tire pressure, which requires the rubber to have excellent air tightness and good heat resistance, aging resistance, and flexing resistance. Appropriate amount of inner tube rubber mixed with tire recycled rubber can not only reduce the cost of raw materials, but also improve the processing performance of inner tube glue, reduce the shrinkage rate of the rubber material, and improve the dimensional stability of semi-finished products.
5. Application of tire recycled rubber in retreaded tires
Refurbished tires have high requirements for the wear resistance, puncture resistance, aging resistance and adhesion to the old carcass of the tread adhesive, and generally use high-strength tire tread recycled adhesive, ultra-fine tire top recycled glue, etc., and the mixing ratio is controlled at 10%-40%. The high proportion of recycled rubber in retreaded tires can not only reduce the cost of raw materials, but also further improve the aging resistance of tread rubber through the carbon black and anti-aging agent components retained in the recycled rubber.
Tire recycled rubber is widely used in the tire manufacturing industry, and we will share with you the vulcanization formula and formula design points of tire tread adhesive, sidewall adhesive, cushion adhesive, inner tube adhesive, and retreaded tire adhesive mixed with tire recycled adhesive.
