Shock absorber rubber

Abstract

The invention discloses a shock absorber rubber which is composed of the following raw materials in parts by mass: 100 parts of nitrile-butadiene rubber, 3-6 parts of zinc oxide, 0.5-2 parts of stearic acid SA, 2-4 parts of anti-aging agent, 1-3 parts of vulcanizing agent, 1-3 parts of accelerator, 1-3 parts of dispersing agent, 8-12 parts of plasticizer DOP and 25-36 parts of reinforcing agent. Compared with the conventional shock absorber rubber, the shock absorber rubber disclosed by the invention has higher shear strength and aging resistance. The accelerators CZ and DM are added to further enhance the vulcanization rate and anti-scorching performance, thereby finally obtaining favorable and stable mechanical properties. The shock absorber rubber has obviously improved high temperature resistance, and has the advantages of favorable fracture strength, favorable elongation at break and favorable hardness.

Description

technical field [0001] The invention relates to the field of rubber products, in particular to shock-absorbing rubber. Background technique [0002] With the rapid development of modern industry, the power of generators is increasing, and the hazards of vibration and noise are becoming more and more prominent. At present, the widely used method is to use rubber materials and skeleton materials (such as metal, fiber, engineering plastics, etc.) Composite shock absorbers or special rubber viscoelastic high damping materials are used to eliminate the vibration impact of the vibration source and absorb noise. The generator generates a lot of heat due to long-term work, and the rubber used for the shock pad of the generator is required to have high strength, High elongation, high wear resistance, high temperature resistance, and avoid thermal aging, but the performance of the current shock-absorbing rubber still cannot meet the needs of the generator, resulting in a huge annual r...
