Embodiment Construction
[0018] The rubber material of the present invention uses part of PDM as auxiliary vulcanizing agent and effective modifier in the natural rubber sulfur vulcanization system to achieve the purpose of improving the high temperature resistance, heat resistance and oxygen aging resistance of natural rubber.
[0019] The raw materials of the rubber material include: 100 parts by weight of natural rubber, 0.5-1.5 parts by weight of sulfur, 0.5-1.5 parts by weight of PDM, 1-2.5 parts by weight of vulcanization aid, 5-10 parts by weight of anti-aging agent, 4-10 parts by weight of zinc oxide The parts by weight are 4-8 parts by weight of white carbon black, 10-30 parts by weight of carbon black, and 4-8 parts by weight of softener. The vulcanizing agent, vulcanization aid, anti-aging agent, zinc oxide and white carbon black are all called fine materials, and the carbon black and softener are all called coarse materials. The vulcanization aid can be MBT (2-mercaptobenzothiazole), MBTS ...
