Problems solved by technology

This has led to the production of general conveyor belts that can no longer meet their special requirements.
At present, most of the existing steel cord flame-retardant conveyor belts contain halogens, which seriously threaten health, corrode equipment and cause environmental pollution.

Abstract

The invention relates to a halogen-free fire-retardant wire rope core conveyor belt for a mine, and the halogen-free fire-retardant wire rope core conveyor belt comprises a wire rope core, an intermediate adhesive layer and covering rubber, wherein the intermediate adhesive layer consists of the following components in parts by weight: 25 to 50 parts of ethylene propylene diene monomer, 30 to 60 parts of thermoplastic elastomer, 30 to 70 parts of halogen-free fire-retardant agent, 1 to 2.5 parts of vulcanizing agent, 15 to 30 parts of carbon black, 2.5 to 4.5 parts of anti-aging agent, 3 to 7 parts of bond and 6 to 10 parts of zinc oxide; and the covering rubber consists of the following components in parts by weight: 50 to 80 parts of ethylene propylene diene monomer, 20 to 70 parts of natural rubber, 50 to 80 parts of halogen-free fire-retardant agent, 2 to 3.5 parts of vulcanizing agent, 20 to 40 parts of carbon black, 1.5 to 4.5 parts of anti-aging agent, 3 to 7 parts of bond and 8 to 20 parts of magnesium oxide. The halogen-free fire-retardent wire rope core conveyor belt has the beneficial effects that by adding the nano-grade modified halogen-free fire-retardant agent, a fire-retardant effect of the conveyor belt can be better realized, and harmlessness can be realized.

Description

technical field [0001] The invention relates to a conveyor belt, in particular to a halogen-free flame retardant steel cord conveyor belt for mines. Background technique [0002] Conveyor belts are widely used in fields such as mining, metallurgy and chemical industry. However, fields such as coal mines have special requirements for conveyor belts, which require good flame retardancy and no harm to the human body. This has led to the production of general conveyor belts that can no longer meet their special requirements. At present, most of the existing steel cord flame-retardant conveyor belts contain halogens, which seriously threaten health, corrode equipment and cause environmental pollution. Contents of the invention [0003] The present invention aims at the deficiencies of the above-mentioned prior art, and provides a halogen-free and flame-retardant steel cord conveyor belt for mines. This conveyor belt not only has good flame retardant performance, but also is ...
