Abstract

The invention provides a flame-retardant high-strength rubber composition which is prepared from the following raw materials in parts by weight: 105 parts of nitrile-butadiene rubber, 50 parts of N220 carbon black, 10 parts of N330 carbon black, 28 parts of dioctyl phthalate, 0.8-1 part of sulfur, 0.8-1 part of dicumyl peroxide, 2 parts of promotor, 2.1 parts of flowable agent, 5 parts of zinc oxide, 3.5-4.5 parts of anti-aging agent, 4-5.2 parts of cracking inhibitor, 30-40 parts of flame retardant and 6 parts of 3% water-emulsion organosilicon releasing agent. As a further improvement, 10-15 parts by weight of antimony trioxide can be added to enhance the flame retardancy. The invention has the characteristics of reasonable formula, favorable flame retardancy, wear resistance, oil resistance and aging resistance.

Description

technical field [0001] The invention relates to a rubber composition, in particular to a rubber composition with good flame retardancy. 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 t...
