EPDM recycled rubber is an environmentally friendly rubber material, and its vulcanization formula and rubber refining process for the production of insulating rubber pads are of great significance for reducing costs. The vulcanization formula and rubber mixing process of insulating rubber pads produced by EPDM recycled rubber are simpler than those of raw rubber, and have the advantages and characteristics of reducing costs under the premise of ensuring quality.
1、EPDM regenerated rubber double vulcanization formula and advantages and characteristics:
Excellent grade EPDM regenerated rubber 35kg, N550 carbon black 3kg, polyethylene glycol 0.3kg, paraffin 0.3kg, zinc oxide 0.7kg, stearic acid 0.45kg, CZ accelerator 0.2kg, DM accelerator 0.15kg, DCP vulcanizing agent 0.08kg, sulfur 0.25kg, TMTD accelerator 0.06kg, vulcanization temperature 160-170 °C, vulcanization time according to the thickness is determined.
Cost reduction: EPDM recycled rubber as a recycled material, compared with natural rubber and synthetic rubber, its price is more economical, can effectively reduce production costs.
Environmental performance: In the production process of EPDM recycled rubber, the dependence on natural resources is reduced, the impact on the environment is reduced, and the requirements of sustainable development are met.
Physical properties: HY1906E3 EPDM reclaimed rubber has good elasticity, wear resistance and aging resistance, which can meet the requirements of insulating rubber pads.
2、the advantages and characteristics of the rubber mixing process:
Mixing process: The rubber refining process of EPDM recycled rubber is relatively simple, and conventional mixing processes, such as open refining, mixing, etc., can be used, which reduces the production cost and technical threshold.
Vulcanization process: The vulcanization process of EPDM regenerated rubber is relatively stable, and the control of vulcanization temperature and time is relatively easy, which can ensure the quality stability of the product.
Processing performance: EPDM recycled rubber has good processing performance, easy to form and process, suitable for the production process of various insulating rubber pads.
Taking a rubber products company as an example, the company uses EPDM recycled rubber to produce insulating rubber pads, and by optimizing the double vulcanization formula and rubber refining process, it not only solves the problem of frost spraying, but also achieves a significant cost reduction effect. Under the premise of ensuring product quality, the production cost per ton of insulating rubber mat is reduced by 10%, which effectively enhances the competitiveness of enterprises.
Through experiments and tests, it can be seen that the vulcanization formula and rubber refining process of EPDM reclaimed rubber have little effect on the physical properties of the insulating rubber pad, and the product meets the requirements of relevant standards. The vulcanization formula and rubber refining process of EPDM reclaimed rubber production insulating rubber pads have the advantages and characteristics of cost reduction. By optimizing formulations and processes, companies can reduce production costs and improve economic efficiency while achieving environmental goals. As an environmentally friendly rubber material, EPDM recycled rubber has broad application prospects.
