Butyl recycled rubber is processed from waste butyl inner tubes as raw materials, with good air tightness, heat resistance, corrosion resistance, damping and shock absorption and other performance characteristics, which can replace butyl rubber in whole or in part, or be used in combination with EPDM and EPDM recycled rubber to produce automotive rubber products, effectively reducing the cost of raw materials. In actual production, which automotive rubber products can use butyl recycled rubber? What are the advantages?
1. Automotive rubber tubes
Butyl rubber inner tubes processed with butyl rubber as the main raw material have the characteristics of high air tightness, heat resistance, elasticity and aging resistance. The price of butyl rubber in the market is high, and the use of butyl recycled rubber in moderation can effectively reduce the cost of raw materials E5LYY717 Compared with pure butyl rubber, the compound mixed with butyl recycled rubber has less shrinkage deformation and better dimensional stability. In the production of automobile inner tubes, 20-60 parts of butyl recycled rubber can be mixed in 100 parts of butyl raw rubber, and the specific mixing ratio should be determined according to the specific needs of the model and inner tube.
2. Automobile tire airtight layer
The tire airtight layer is the breathable rubber layer on the inner surface of the tubeless tire and the contact surface among the bead and the rim bead seat, which requires the rubber to have good air permeability, aging resistance and adhesion, sufficient tensile strength and tear elongation, and is mostly processed by butyl rubber. Butyl recycled rubber can be used in an appropriate ratio with butyl rubber to produce automobile tire airtight layer adhesive, which can reduce raw material costs and production energy consumption on the premise of ensuring the performance of the finished product.
3. Automotive rubber seals
There are many rubber seals in automobiles, including sealing gaskets, sealing strips and sealing rings, etc., which are used to seal engines, transmissions, doors and other parts. Butyl recycled rubber has high air tightness, chemical resistance and aging resistance, etc., and can be used in conjunction with butyl rubber and EPDM rubber to produce rubber seals to prevent the intrusion of external dust and moisture, and ensure the normal operation and service life of various parts of the automobile.
4. Automotive shock absorbing materials
Rubber shock absorbers and soundproofing components need to be used in car driving to reduce vibration and noise during car driving; Butyl recycled rubber has the characteristics of good elasticity, flex resistance, shock absorption and damping, and can be used in the production of automobile shock absorbing materials to absorb and buffer the vibration energy generated during car driving and improve driving comfort.
5. Tire vulcanization capsules
Tire vulcanization capsules are the key components of tire vulcanization molding, which directly affects the dimensional accuracy, appearance quality and production efficiency of tires, and has high requirements for fatigue resistance, heat aging resistance, media resistance, dimensional stability and low compression set of the compound. When using butyl rubber as the main raw material to produce tire vulcanization capsules, the rational use of butyl recycled rubber can not only reduce the cost of raw materials, but also improve the performance of the rubber processing process.
Different varieties of automotive rubber products have different performance requirements, different usage and dosage of butyl recycled rubber, and later share with you the application skills and vulcanization formulas of butyl recycled rubber in automobile tubes, tire airtight layers, rubber seals, gaskets, shock absorbing materials and vulcanized capsules.
