The invention provides a weather-resistant and anti-aging rubber composition for dust prevention of shock absorbers, which comprises 100 portions of nitrile butadiene rubber by weight, 45 portions of N220 carbon black by weight, 20 portions of N330 carbon black by weight, 20 portions of dioctyl by weight, 0.8-1 part of sulfur by weight, 0.8-1 part of dicumyl peroxide by weight, 2 portions of accelerator by weight, 1.8 portions of flowable agent by weight, 5 portions of zinc oxide by weight, 3.5-4.5 portions of anti-aging agent by weight and 2.5-3.2 portions of anti-cracking agent B10 by weight. The rubber composition solves the problems of poor quality of the former rubber products for the dust prevention of the shock absorbers used in auto-bikes and cars, no weather resistance and durability, low anti-fatigue flexibility and easy cracking, and the method has the advantages of more reasonable formula, better comprehensive properties with regards to elasticity, weather resistance, anti-aging and oil-proof properties. As a further improvement, 0.3 part of N, N'-diphenyl-para-phenylene diamine by weight is added to the components to more excellent ozone-resistant performance.
Description
technical field [0001] The invention relates to a rubber composition, in particular to a rubber composition used for dust-proofing of motorcycles and automobile shock absorbers. Background technique [0002] The rubber composition currently used for motorcycles and automobile shock absorbers to prevent dust, the common general components are nitrile rubber 100, N330 carbon black 65, dibutyl fat 20, sulfur 1.8, accelerator 2.5, flow agent 2, anti-aging Agent 4, Zinc Oxide 5, Paraffin 1.5-2.5. There is also a composition of nitrile rubber 100, N330 carbon black 35, N220 carbon black 30, dibutyl fat 20, sulfur 0.5, dicumyl peroxide 3, accelerator 1.5, flow agent 2, anti-aging agent 4, oxidation Zinc 5, paraffin 1.5-2.5. The rubber products made of these two components are of low quality, not weather-resistant, not durable, have low fatigue resistance and flexibility, are easy to crack, and are not good enough in quality and reliability when used for shock absorber dustproof. ...
