Abstract

The invention relates to a hydrogenated nitrile butadiene rubber material and in particular relates to a rubber material for a liner bushing of a track-laying vehicle. The material is prepared from the following components in parts by mass: 100 parts of hydrogenated nitrile butadiene rubber, 3 to 5 parts of zinc oxide, 0.5 to 1.0 part of (industrial-grade) stearic acid, 0.5 to 1.0 part of an (industrial-grade) anti-ageing agent TMQ, 0.5 to 1.0 part of an (industrial-grade) anti-ageing agent 4010NA, 2 to 3.5 parts of BIBP (Bis(tert-butyldioxyisopropyl)benzene) (with the purity of 96 percent), 0.5 to 1.5 parts of HVA-2, 0.5 to 1.0 part of sulfur, 0.5 to 0.6 part of DTDM (Dithiodimorpholine), 0.5 to 0.6 part of CZ, 30 to 35 parts of carbon black, 5 to 8 parts of white carbon black, 5 to 15 parts of zinc methacrylate, 3 to 5 parts of a plasticizer DOS (Dioctyl Sebacate) and 1 to 2 parts of a dispersion auxiliary agent. The material provided by the invention has the advantages of excellenthigh temperature resistance, ageing resistance, flexing resistance, ozone resistance, oil resistance, strength and tensile performance, has good adhesion performance with a carbon fiber material and has a long service life.

Description

technical field [0001] The invention relates to a hydrogenated nitrile rubber material, in particular to a rubber material for a track vehicle bushing. technical background [0002] The rubber bushing components of crawler-type special vehicles are affected by multiple factors such as fatigue heat generation, flexure, ozone, dust, moisture, oil pollution, etc., resulting in cracking, cracking, and degumming of the rubber material, resulting in failure of the bushing. In order to meet the performance requirements of the rubber bushing parts of tracked special vehicles, the Shore A hardness of the rubber material is required to be 65-70, the tensile strength is greater than 24MPa, the peel strength between the carbon fiber composite material and the rubber matrix is ​​greater than 5KN / m, and has good Excellent fatigue resistance, cracking resistance and cracking performance. The combination of carbon fiber composite materials and rubber can give full play to the advantages of...
