Problems solved by technology

[0003] Due to the particularity of conveying materials, the materials are not only oily but also flammable. However, at present, domestic oil-resistant and flame-retardant conveyor belt products are still blank, and most of them are single-standard products.
Some are only oil-resistant but do not meet the national safety production indicators, and some are only flame-retardant and the oiliness of the material penetrates into the rubber to absorb oil and swell and fall off, so these products basically have the problem of short service life.

Abstract

The invention discloses an oilproof and flame retardant conveyor belt, belonging to the technical field of conveying materials. Cover rubbers and middle bonding rubber masses of the conveyor belt comprise the following components based on weight proportions: 20-40 parts of neoprene, 60-80 parts of nitrile rubbers containing propylene, 15-20 parts of chlorinated polyethylene, 50-70 parts of compound flame retardant, 3-5 parts of combined dispersant, 3-5 parts of zinc oxide, 1-2 parts of stearic acid, 1.0-1.5 parts of accelerators, 3-5 parts of age inhibitors, 40-50 parts of carbon black and 2.0-3.0 parts of sulfur. The oilproof and flame retardant properties of the conveyor belt are greatly improved; the oilproof property reaches related national standard (HG/T3714-2003) and the flame retardant property also meets the national security requirement (GB/T10082-2003).

Description

technical field [0001] The invention relates to a conveyor belt, in particular to an oil-resistant and flame-retardant conveyor belt, which belongs to the technical field of conveying materials. Background technique [0002] In recent years, with the rapid development of my country's economy, especially the rapid development of the wharf, food and other industries, the oil-resistant and flame-retardant conveyor belt is playing an increasingly important role in the transportation of special materials such as grain and oil. [0003] Due to the particularity of conveying materials, the materials are not only oily but also flammable. However, there are still no oil-resistant and flame-retardant conveyor belt products in China, and most of them are single-standard products. Some are only oil resistant but do not meet the national safety production indicators, and some are only flame retardant and the oiliness of the material penetrates into the rubber to absorb oil and swell and ...
