Anti-electrostatic oil-corrosion-resistant type polyester core conveyer belt

Abstract

The invention discloses an anti-electrostatic oil-corrosion-resistant type polyester core conveyer belt which is characterized by consisting of the following components in parts by weight: 30-35 parts of modified chloroprene rubber, 20-25 parts of nitrile rubber containing 30% propylene, 8-10 parts of a composite flame retardant, 0.6-0.8 part of potassium aliphatate, 2-3 parts of zinc oxide, 1-2 parts of stearic acid, 0.7-0.9 part of tert-butyl peroxybenzoate, 1.5-1.8 parts of an accelerant TMTD, 10-12 parts of polyester canvas, 15-16 parts of carbon black and 3-4 parts of sulfur. The anti-electrostatic oil-corrosion-resistant type polyester core conveyer belt disclosed by the invention is high in strength, remarkably high in oil corrosion resistance and electrostatic resistance and can be widely applied to industries such as the coal industry, the petroleum industry and the paper-making industry as the static electricity generated when the conveyer belt is used can be effectively leaked off, and the damage of fire hazard can be effectively reduced due to addition of the composite flame retardant.

Description

technical field [0001] The invention belongs to the technical field of conveying materials, and in particular relates to an antistatic, oil-resistant and corrosion-resistant polyester core conveyer belt. Background technique [0002] Cotton canvas and polyester canvas are used as the skeleton material for the polyester core conveyor belt, and butyl rubber or oxidized butyl rubber with good heat resistance is used for the cover rubber and buffer rubber. This new product can be used normally at a temperature below 120°C, and is suitable for conveying materials whose temperature is below 120°C. Widely used in cement, coking, metallurgy, steel and other industries. Polyester conveyor belt is also called EP conveyor belt. Its body is polyester in the warp direction and canvas interwoven with cotton fibers in the weft direction. Its performance characteristics are low elongation in the warp direction and excellent grooving performance in the weft direction. Good water resistance...

AI Technical Summary

Problems solved by technology

However, the prior art is not ideal for improving the performance of the base rubber, especially for heat resistance, oil resistance, and antistatic performance.

Due to the particularity of conveying materials, the materials are not only oily but also flammable. However, some domestic conveyor belt products are only oil-resistant and some are only flame-retardant, so these products basically have the problem of short service life.
