Abstract
The invention discloses a rubber composition for a leaf spring lug bushing for an automobile. The rubber composition is characterized by comprising the following components in parts by weight: 100 parts of rubber, 1.5-3 parts of a p-phenylenediamine type anti deteriorant, 1.5-3 parts of a hydrogenated quinoline type anti deteriorant, 3-5 parts of microcrystalline wax, 5-8 parts of an active agent, 1-2 parts of stearic acid, 3-6 parts of resin, 3-5 parts of a processing addition agent, 5-8 parts of a slipping agent, 3-5 parts of a fatty oil plastifier, 5-10 parts of a petroleum plastifier, 60-95 parts of carbon black, 1.5-2.1 parts of an accelerant, and 1.5-1.8 parts of a vulcanizing agent. Through the adoption of the rubber composition disclosed by the invention, the lubricating property between the lug bushing and a bearing is improved, the friction noise is reduced, and the abrasion resistance is improved, so that the lug bushing is not invalid under the long-term use state, under the circumstance that the cost is not increased, the fabrication process is simple, and the lug bushing is convenient to use and mount.
Description
technical field [0001] The invention relates to a rubber composition of a leaf spring lug bush for automobiles, which belongs to the technical field of rubber chemical industry. Background technique [0002] Automotive leaf spring lug bushings such as figure 1 As shown, especially the leaf spring lug bushes used in small trucks and trucks are indispensable vibration damping and buffering parts. During its use, especially when walking on a bumpy road after loading, the lifting lug bush is bearing the extrusion force, deformation and wear from different directions. Many car owners often use the lifting lug bush for 2000 kilometers. Extrusion failure and damage caused the chassis of the vehicle body to squeak during driving, and the effects of vibration reduction and cushioning also failed. Contents of the invention [0003] What the invention aims to solve is the technical problem that the existing automotive leaf spring lug bushing has poor extrusion resistance and is pro...
