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 ...

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a rubber material and a preparation method thereof. Background technique [0002] The automotive industry has continuously improved the heat and oxygen aging resistance requirements of natural rubber shock absorbers, especially for products such as rubber shock absorbers for automobile engines and rubber shock absorbers for gearboxes, which are required to withstand high-intensity heat in ultra-high temperature and ultra-long-term environments. Oxygen aging can meet the development needs of high temperature thermal oxygen aging dynamic fatigue performance in the automotive industry. [0003] Due to the characteristics of natural rubber materials that are not resistant to high temperature thermal oxygen aging, ozone resistance and weather resistance, it is difficult to meet the continuously improving technical requirements of the automotive industry. Improving and improv...
