Good-airtightness anti-aging tire rubber material

Abstract

The invention discloses a good-airtightness anti-aging tire rubber material. The good-airtightness anti-aging tire rubber material is prepared from the following raw materials in parts by weight: 25 to 35 parts of nitrile butadiene rubber, 2 to 8 parts of polyurethane, 12 to 16 parts of ethylene-propylene copolymer, 5 to 12 parts of phenolic resin, 0.2 to 0.6 part of ammonium dichromate, 1 to 2 parts of dibenzothiazyl disulfide, 0.5 to 1.5 parts of oleic acid, 1 to 2 parts of stearic acid, 20 to 30 parts of modified cotton fiber, 2 to 8 parts of kaolin, 5 to 10 parts of feldspar, 40 to 50 parts of lardite, 2 to 8 parts of limestone, 1 to 5 parts of apatite, 5 to 15 parts of ceramic microspheres, 1 to 3 parts of acetyl tributyl citrate, 1 to 2 parts of polyethylene wax, 1 to 2 parts of chlorinated paraffin, 0.5 to 1.5 parts of antioxidant AT-215, 1 to 2 parts of ultraviolet absorber UV-531 and 1 to 2 parts of ultraviolet absorber TB75. The good-airtightness anti-aging tire rubber material disclosed by the invention is good in tearing resistance, excellent in sealing performance and good in aging resistance.

Description

technical field

[0001] The invention relates to the technical field of rubber tires, in particular to a tire rubber material with good sealing performance and aging resistance. Background technique

[0002] As the main accessories of automobiles, tires are unavoidable to be worn and punctured during use, especially when a tire blows out in a high-speed automobile, it is very easy to cause serious accidents such as car crashes and fatalities. Therefore, various manufacturers are constantly improving the safety, environmental protection, and energy-saving requirements of tires. In order to prevent tires from exploding, the tear resistance, sealing performance and aging resistance of existing rubber tires cannot meet the needs and need to be solved urgently.
