Abstract

The invention provides a special wear-resisting rubber composite, which comprises the following components in part by weight: 105 parts of nitrile butadiene rubber, 55 parts of N220 carbon black, 15 parts of N330 carbon black, 30 parts of dioctyl phthalate, 0.8 to 1 part of sulfur, 0.8 to 1 part of dicumyl peroxide, 2 parts of accelerator, 2.1 parts of flowable agent, 5 parts of zinc oxide, 3.5 to 4.5 parts of antioxidant and 4 to 5.2 parts of cracking inhibitor. As further improvement, 0.5 part of N,N'-diphenyl-phenylene diamine is added into the components, so that the special abrasive rubber composite has better ozone resistance. The special wear-resisting rubber composite is characterized by more reasonable formula and excellent combination property of elasticity, weatherability, ageing resistance and oil resistance.

Description

technical field [0001] The invention relates to a rubber composition, in particular to a rubber composition with good wear resistance. Background technique [0002] There are thousands of formulas and manufacturing methods for rubber compositions, and different material formulas are often provided according to different use requirements. The common general components commonly used at present with weather resistance and wear resistance are nitrile rubber 100, N330 carbon black 65, dibutyl fat 20, sulfur 1.8, accelerator 2.5, flow agent 2, antioxidant 4, zinc oxide 5, paraffin wax 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...
