Embodiment Construction

[0019] The following specific embodiments further illustrate the present invention.

[0020] A rubber material, including 70 parts of natural rubber, 30 parts of polyurethane rubber, 0.5-1.5 parts of sulfur, 1-2.5 parts of vulcanization aid, 5-10 parts of anti-aging agent, 4-10 parts of zinc oxide, and 4 parts of white carbon black ~8 parts, carbon black 10~30 parts, softener 4~8 parts. Natural rubber and polyurethane rubber (E6008) are used together, polyester and polyether are mixed into the molecular chain of isoprene rubber as a flexible segment of rubber, and sulfur vulcanization system is used to improve the heat and oxygen resistance of natural rubber. (High temperature) aging, ozone aging resistance purpose.

[0021] As preferably, the vulcanization aid adopts 2-mercaptobenzothiazole, dibenzothiazole disulfide, N-cyclohexyl-2-benzothiazole sulfenamide, tetramethylthiuram disulfide, disulfide disulfide One or more of 1,5-pentylidene thiurams.

Abstract

The invention discloses a rubber material. The rubber material comprises 70 parts by weight of natural rubber, 30 parts by weight of polyurethane rubber (E6008), 0.5-1.5 parts by weight of sulfur, 1-2.5 parts by weight of a vulcanizing agent, 5-10 parts by weight of an anti-aging agent, 4-10 parts by weight of zinc oxide, 4-8 parts by weight of white carbon black, 10-30 parts by weight of carbon black and 4-8 parts by weight of a softening agent. According to the rubber material, the natural rubber and the polyurethane rubber (E6008) are used together, and polyester and polyether are blended in an isoprene rubber molecular chain and serve as a flexible chain section of the rubber.

Description

technical field [0001] The invention relates to the field of rubber materials, more specifically, it relates to a rubber material. Background technique [0002] The automotive industry has continuously improved the heat and oxygen aging resistance requirements of natural rubber shock absorbers, especially automotive engine gearbox support products, which are required to withstand high-intensity thermal oxygen aging in ultra-high temperature and ultra-long-term environments. The automotive engine gearbox support products The service life of dynamic fatigue has been increased from 100,000 times to more than 180,000 times in order to meet the development needs of the automotive industry for high-temperature thermal-oxidative aging dynamic fatigue performance. [0003] Since the natural rubber material itself is not resistant to high temperature thermal oxygen aging, and has poor ozone resistance and weather resistance, it is difficult to meet the continuously improving technica...
