Rubber waterproof coiled material has high strength, good extensibility, tear resistance, aging resistance, strong temperature adaptability, long service life, and an increasing proportion in waterproof materials. In actual production, neoprene rubber, butyl rubber, EPDM rubber, polyurethane rubber, chlorinated polyethylene rubber, etc. can be used as the main materials of waterproof coiled materials. EPDM recycled rubber has the basic performance characteristics of EPDM raw rubber and good aging resistance. Can it replace EPDM to produce waterproof roll? How to add appropriate?
1. Separate use of EPDM recycled rubber to produce waterproof roll
EPDM reclaimed rubber takes EPDM machine head rubber, unvulcanized EPDM rubber, waste products of automobile sealing strips that do not meet the standards, washing machine sealing rings, etc. as raw materials, and adopts high-temperature chemical regeneration, microwave regeneration, ultrasonic regeneration and other desulfurization regeneration methods. The reclaimed rubber 2SLYY216 has high and low temperature resistance, aging resistance, ozone resistance, corrosion resistance and other performance characteristics. In actual production, EPDM recycled rubber can directly replace EPDM raw rubber to produce rubber waterproof rolls, effectively reducing the cost of raw materials and reducing the cost of electricity.
2. EPDM recycled rubber and EPDM rubber are used together to produce waterproof roll
EPDM recycled rubber has good compatibility with EPDM, which can replace a certain proportion of EPDM and produce rubber waterproof coiled materials with EPDM, effectively reducing raw material costs and reducing production energy consumption on the premise of ensuring product quality. In actual production, when EPDM/EPDM recycled rubber is used together to produce rubber waterproof rolls, the extrusion speed of the rubber is faster, the shrinkage of semi-finished products is small, and the film specification stability is good.
3. EPDM recycled rubber and butyl rubber are used together to produce waterproof roll
Butyl rubber has good heat resistance, ozone resistance, weather aging resistance, strong acid resistance and other characteristics. It is an ideal raw material for producing rubber waterproof roll. EPDM recycled rubber can be used in a small amount in rubber waterproof coiled materials with butyl rubber as the main raw material, which can not only reduce the cost of raw materials, but also further improve the curing property of butyl rubber and the aging resistance of waterproof coiled materials, and extend the service life.
In actual production, rubber product manufacturers can also use EPDM, butyl rubber and EPDM recycled rubber together, and use butyl recycled rubber appropriately when necessary; If there is a chance, Xiaobian will continue to share with you the vulcanization formula of EPDM recycled rubber to produce rubber waterproof roll.
