Problems solved by technology

This technology has a good effect in actual production, but there are still some limitations, mainly because the rubber composition is easy to foam on the surface of the finished product during the production process, and the composition is used at high temperature for a long time. Afterwards, there is a pungent smell. In addition, the patent has an obvious disadvantage of poor flame retardancy, and its use in some special fields is limited.

Abstract

The present invention provides a fire-retardant and wear-resisting rubber composition, prepared by the following raw materials: 100 parts by weight of acrylonitrile-butadiene rubber, 40 parts by weight of N220 carbon black, 10 parts by weight of N330 carbon black, 20 parts by weight of dioctyl phthalate, 0.8 to 1 part by weight of sulphur, 0.8 to 1 part by weight of dicumyl peroxide, 3 to 3.5 parts by weight of promoter, 3 to 3.5 parts by weight of flowable agent, 5 to 6 parts by weight of zinc oxide, 3.5 to 4 parts by weight of antiager, 4 to 5 parts by weight of crack-preventing agent, 8 to 10 parts by weight of defoaming agent, 3 to 5 parts by weight of musk xylene, 30 to 40 parts by weight of fire retardant and 2 to 4 parts by weight of 2% water emulsified organosilicon mold lubricant. Characteristics of the rubber composition: formula is more reasonable; the rubber composition is not easy to foam in processing, with certain fragrant smell radiated, and sealing and wear-resisting performances are good.

Description

Technical field [0001] The invention relates to a rubber composition, in particular to a rubber composition with flame-retardant and wear-resistant properties. Background technique [0002] There are thousands of formulas and manufacturing methods for rubber compositions, which are often equipped with different material formulas according to different usage requirements. The commonly used common components with weather resistance and wear resistance are nitrile rubber 100, N330 carbon black 65, dibutyl 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 20, sulfur 0.5, dicumyl peroxide 3, accelerator 1.5, flow agent 2, antioxidant 4, oxidation Zinc 5, paraffin wax 1.5-2.5. The rubber products made of these two components are of low quality, are not weather-resistant, unused, have low fatigue resistance, are easy to crack, and are ...
