Beschreibung
Zusammenfassung:	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.
