Heat-resistant rubber conveyor belts are widely used in steel, cement, chemical, glass and other industries to convey materials in high-temperature environments. The conveyor belt covering rubber is in direct contact with the transported material, which protects the belt core from the impact, wear and corrosion of the material during work, and prolongs the service life of the conveyor belt. In actual production, the heat-resistant rubber conveyor belt covering rubber is usually made of ethylene propylene rubber, or used in combination with a small amount of butyl rubber, and the finished product has good heat resistance and high chemical stability; The rational use of EPDM reclaimed rubber can effectively reduce costs.
1. EPDM reclaimed rubber and ethylene propylene rubber are used together to produce heat-resistant conveyor belt covering rubber
The combination of EPDM reclaimed rubber and ethylene propylene rubber is a common way to produce heat-resistant conveyor belt covering rubber. As a low-cost option to EPDM raw rubber, EPDM reclaimed rubber can significantly reduce the cost of raw materials while maintaining good heat resistance and E4LYY58 performance. In the formulation design, low-sulfur compounding or peroxide vulcanization system is usually used to improve the heat aging resistance of vulcanized rubber. In addition, highly wear-resistant carbon black or gas-mixed carbon black is often used in the reinforcing filling system to enhance the hardness of the rubber compound and prevent high-temperature cracking.
2. EPDM reclaimed rubber and butyl rubber are used together to produce heat-resistant conveyor belt covering rubber
EPDM reclaimed rubber can also be used in combination with butyl rubber to produce heat-resistant conveyor belt covering rubber. Butyl rubber has excellent air tightness and heat resistance, and when used in combination with EPDM reclaimed rubber, the comprehensive performance of the covering rubber can be further improved. In practical applications, this combination not only reduces costs, but also improves the heat resistance and aging resistance of the compound through the properties of butyl rubber.
3. EPDM reclaimed rubber is used together with ethylene propylene rubber and butyl rubber to produce heat-resistant conveyor belt covering rubber
EPDM reclaimed rubber can be used in combination with ethylene propylene rubber and butyl rubber to form a composite formula. This combination combines the advantages of the three, which not only takes advantage of the cost advantage of EPDM reclaimed rubber, but also uses the air tightness of butyl rubber and the heat resistance of ethylene propylene rubber; Reasonable design of heat-resistant rubber conveyor belt covering rubber formula can achieve the stable performance of covering rubber in high temperature environment, and at the same time meet the requirements of heat resistance, wear resistance and aging resistance.
The application of EPDM reclaimed rubber in heat-resistant rubber conveyor belt covering rubber can not only effectively reduce production costs, but also improve the heat resistance, wear resistance and aging resistance of the covering rubber by combining it with ethylene propylene rubber and butyl rubber. Choosing the right combination of proportions and formulation design is the key to achieving a balance of high performance and economy for heat-resistant conveyor belts.
