Problems solved by technology

Considering the conditions of use and processing performance, a rubber with high hardness, oil resistance and good processability is needed, but the rubber currently on the market cannot meet the demand, or it can meet one requirement and the other two requirements cannot be met. Either it meets two of the requirements and cannot meet the other requirement, so the existing rubber cannot satisfy the characteristics of high hardness, oil resistance and good processability at the same time.

Abstract

The invention is suitable for the technical field of rubber and provides rubber for buffering supporting piece in an automobile. The rubber comprises or includes the following components in parts by weight: 70-90 parts of nitrile rubber buna, 10-30 parts of high styrene, 1-3 parts of a dihydroquinoline antiaging agent, 1-3 parts of a p-phenylenediamine antiaging agent, 1-4 parts of paraffin, 4-8 parts of an activator, 1-3 parts of stearic acid, 60-100 parts of a reinforcing agent, 0.5-2.5 parts of a vulcanizing agent and 2-5 parts of an accelerant. By using the nitrile rubber buna, the oil resistance of the rubber obtained is greatly improved, so that the product is maintained in a good performance and shape in a working environment filled with oil. By using the high styrene, the hardness of the rubber can be remarkably improved, and the rubber has high hardness on the premise that the filling amount of the rubber product is not high.

Description

technical field [0001] The invention belongs to the technical field of rubber, and in particular relates to a rubber with high hardness, good oil resistance and good processability, which is used for the buffer support parts in automobiles. Background technique [0002] The main function of the automobile shock absorber is buffering and vibration isolation. It can be said that the comfort of the car when driving directly depends on the shock absorber in the car, and the rubber parts are installed on the limiter of the shock absorber connecting rod to play a limiting role. Position, cushioning, vibration isolation, and the connecting rod limiter is filled with hydraulic oil, which requires that the rubber of the inner buffer support must have oil resistance and high hardness, so as to ensure that it is not easy to produce performance during use. changes and play an excellent role in vibration isolation and buffering. Considering the conditions of use and processing performan...
