Butyl reclaimed rubber is made of waste butyl inner tube as raw material, and is made by crushing, desulfurization, refining and other processes, which retains the basic performance characteristics of butyl rubber, good air tightness, heat resistance, water resistance, chemical resistance, and can be used in combination with original rubber to produce rubber products, improve the performance of rubber products, and reduce the cost of rubber materials. In actual production, which rubbers can butyl reclaimed rubber be used with? What are the advantages? Where can it be used?
1. Butyl reclaimed rubber and butyl rubber are used together
The combination of butyl reclaimed rubber and butyl rubber is a commonly used method for industrial rubber products. The use of butyl reclaimed rubber in butyl rubber can not only reduce the cost of raw rubber, but also improve the problems of difficult rubber cutting, easy sticking rollers, and slow eating speed of compounding agent during butyl rubber processing. Adding butyl rubber to butyl reclaimed rubber can further improve the air tightness, heat resistance and chemical stability of the finished product. Butyl reclaimed rubber is often used in combination with butyl rubber to produce rubber inner tubes, sealing gaskets, hoses, tapes, shock-absorbing rubber and rubber rollers.
2. Butyl reclaimed rubber and ethylene propylene rubber are used together
Ethylene propylene rubber is a synthetic rubber with ethylene and propylene as the main monomers, and has excellent aging resistance. Butyl rubber becomes soft and hardness decreases after aging, and ethylene propylene rubber hardens and increases hardness after aging. The combination of butyl reclaimed rubber and EPDM rubber can improve the defects of butyl rubber softening after aging, and make the hardness change of the product more stable during the aging process. For example, the use of a small amount of EPDM reclaimed rubber in butyl inner tubes can reduce the excessive softening or hardening of the inner tube during long-term use and aging, and maintain the use performance.
The combination of butyl reclaimed rubber and ethylene propylene rubber can produce automotive rubber parts, wires and cables, etc., reducing costs while improving the processing performance of rubber compounds and improving the adhesion of rubber compounds.
3. Butyl reclaimed rubber and neoprene are used together
Neoprene is produced by α-polymerization of chloroprene as the main raw material, and has excellent oil resistance, heat resistance, ozone resistance, acid and alkali resistance. The combination of butyl reclaimed rubber and neoprene rubber in an appropriate ratio can significantly improve the oil resistance and aging resistance of the product. When using neoprene/butyl reclaimed rubber and glue to prepare oil-resistant seals and hoses, neoprene can provide good oil resistance and heat resistance, and the cost and aging resistance are better after adding butyl reclaimed rubber.
4. Butyl reclaimed rubber is used in conjunction with natural rubber
The price of butyl reclaimed rubber is much lower than that of natural rubber, and the appropriate use of butyl reclaimed rubber in natural rubber products can effectively reduce the cost of raw materials. Butyl reclaimed rubber retains the characteristics of good air tightness of butyl rubber E4LYY516 and can be used in combination with natural rubber to significantly improve the air tightness of products, which can be used to produce rubber inner tubes, balls and other products with high air tightness requirements to reduce the occurrence of gas leakage; Butyl reclaimed rubber has good heat resistance and aging resistance, and when used in combination with natural rubber, it can improve the overall aging resistance of the product and prolong the service life of the product in different environments.
5. Butyl reclaimed rubber and butadiene rubber are used together
Butadiene rubber is a synthetic rubber with a regular structure made of butadiene polymerization, which has the characteristics of high elasticity, good wear resistance, good cold resistance, low heat generation, good flexibility resistance and dynamic performance. The combination of butyl reclaimed rubber and appropriate amount of butadiene rubber can significantly improve the crack resistance of butyl reclaimed rubber under dynamic conditions, and is suitable for the production of automobile tires and conveyor belts.
In actual production, butyl reclaimed rubber can also be used in combination with chlorinated butyl rubber, brominated butyl rubber or styrene-butadiene rubber; In order to further reduce costs, butyl reclaimed rubber can also be used in combination with chlorinated butyl reclaimed rubber, EPDM reclaimed rubber, tire reclaimed rubber, etc. According to different application needs, butyl reclaimed rubber needs to choose the right combined rubber to improve the performance of rubber products and reduce costs.
