EPDM reclaimed rubber and EPDM plastic, with good high temperature performance, can replace the production of rubber raw rubber. However, the incorporation of EPDM reclaimed rubber in rubber products or the complete use of EPDM reclaimed rubber is different from the production of pure EPDM rubber rubber, either in formula or in process.
1, recipe:
(1) EPDM reclaimed rubber is a resource for the recycling of waste EPDM rubber, which itself contains a certain amount of water, softener and accelerant; the production of waste EPDM requires desulfurization and desulfurization will be promoted in large quantities Agents, zinc oxide, stearic acid, curing agents, these substances can not be separated after the production of EPDM reclaimed rubber is completed.
Therefore, the development formula containing EPDM reclaimed rubber products, it is necessary to consider the reclaimed rubber itself contains water, curing agent, accelerator, softening and other chemical additives, appropriate to reduce the amount of these substances.
(2) Use of EPDM reclaimed rubber instead of EPDM rubber In the production of rubber products, the quantity of gums should be replaced by the same amount of plasticizer.
(3) If you want to improve the quality of EPDM reclaimed rubber products, it is best to add a small amount of EPDM in the product formula.
2, technology:
EPDM reclaimed rubber in the production process has been fully mixed, so in the production of rubber products without plasticizing again, the process is simple; if it is EPDM reclaimed rubber and raw rubber used in conjunction with the production of rubber products, in the original Plastic plastic refining after the addition of EPDM renewable rubber can be.
The use of EPDM reclaimed rubber production of rubber products and the use of raw rubber production of rubber products is essentially different, so rubber products companies must pay attention to adjust the formula, do not think that as long as the EPDM glue can be replaced, that is Take your product quality and brand joke.
