High-strength oil-resistant figured conveyor belt

Abstract

The invention discloses a high-strength oil-resistant figured conveyor belt. A raw material of the high-strength oil-resistant figured conveyor belt comprises following ingredients, by weight, 40 to 55 parts of modified butadiene-acrylonitrile rubber, 30 to 40 parts of hydrogenated butadiene-acrylonitrile rubber, 3 to 5 parts of zinc borate, 1 to 2 parts of tricresyl phosphate, 4 to 6 parts of sulphur, 3 to 5 parts of stearic acid, 6 to 8 parts of medium particle thermal cracking carbon black N990, 8 to 12 parts of kaolin, 0.6 to 0.8 part of anti-aging agent MB, 0.3 to 0.5 part of promoter DM, 1 to 3 parts of paraffin, 1.2 to 1.5 parts of dibutyl phthalate, 2 to 4 parts of trithiocyanuric acid, and 0.4 to 0.6 part of triallyl isocyanurate. The raw material is high in mechanical strength and pulse resistance; strength of the high-strength oil-resistant figured conveyor belt is increased, oil resistance and heat resistance are improved, and safety guarantee of products is improved.

Description

technical field [0001] The invention belongs to the technical field of rubber products, and in particular relates to a high-strength oil-resistant pattern conveyor belt. Background technique [0002] Hydrogenated nitrile rubber is a highly saturated elastomer obtained by special hydrogenation of nitrile rubber. Hydrogenated nitrile rubber has good oil resistance (good resistance to fuel oil, lubricating oil, and aromatic solvents); and due to its highly saturated structure, it has good heat resistance and excellent chemical corrosion resistance (to Freon, acid and alkali have good resistance), excellent ozone resistance, high compression set resistance; at the same time, hydrogenated nitrile rubber also has high strength, high tear performance, excellent wear resistance and other characteristics. It is one of the rubbers with excellent comprehensive properties. [0003] Nitrile rubber has excellent oil resistance, second only to polysulfide rubber and fluorine rubber, and ...

Problems solved by technology

However, carbon black, a reinforcing filler for rubber, will produce a large amount of carbon black dust pollution during the production process, which is a traditional pollution source in the rubber processing process and is difficult to cure. Therefore, a more environmentally friendly, resource-saving and reliable method is adopted It is urgently needed to reinforce the conveyor belt filled with nitrile rubber
