Energy-saving wear-resistant low-smoke halogen-free fire-retardant steel wire rope core conveyor belt and manufacturing method thereof

Abstract

The invention discloses an energy-saving wear-resistant low-smoke halogen-free fire-retardant steel wire rope core conveyor belt and a manufacturing method thereof. Tin coupled solution polymerized styrene butadiene rubber (SSBR) / natural rubber / butadiene rubber is taken as the host material; carbon black with low rolling resistance and high dispersion white carbon black are taken as the reinforcing agent; a halogen-free fire retardant and a plasticizer are added; by optimizing the formula and technology, an energy-saving wear-resistant low-smoke halogen-free fire-retardant rubber composite material is used as a cover layer, can meet the requirements on mechanical properties of the steel wire rope core conveyor belt, and also has an excellent wear-resistant performance and impact resistantperformance; moreover, the fire-resistant performance is good, the rolling resistance is low, the conveyor belt is energy-saving and environmentally-friendly; the service life of the conveyor belt isprolonged, and the drive power of the conveying machine is reduced. The technology is simple, and the manufacturing is easy.

Description

technical field [0001] The invention relates to the technical field of mine conveyor belts, in particular to an energy-saving, wear-resistant, low-smoke, halogen-free, flame-retardant steel cord conveyor belt and a manufacturing method thereof. Background technique [0002] Steel cord conveyor belt is the main tool for conveying coal underground in coal mines. According to coal mine safety regulations, steel cord conveyor belts used in underground must have flame-retardant and antistatic properties, in line with MT668-2008 "Coal Mine Steel Cord Flame-Retardant Conveyor Belt", This standard has higher requirements on the flame retardant performance of the conveyor belt, and lower requirements on the mechanical properties of the covering layer. The flame retardant and antistatic performance of the steel cord core flame retardant conveyor belt produced by the current technology is better. The main problem is that the mechanical properties of the covering layer are low, and the ...

AI Technical Summary

Problems solved by technology

The flame retardant and antistatic performance of the steel cord core flame retardant conveyor belt produced by the current technology is better. The main problem is that the mechanical properties of the covering layer are low, and the outstanding performance is poor wear resistance and impact resistance, and the service life is short; the second is the use of Halogen-containing main materials and halogen- and antimony-containing flame retardants, when the flame-retardant tape is ignited, the amount of smoke is large, and the smoke contains halogen, which is prone to secondary disasters such as personnel poisoning, corrosion of equipment, and environmental pollution; the third is to use High rolling resistance and high energy consumption during the process

At present, there are many researches on how to improve the flame-retardant and adhesive properties of steel cord flame-retardant conveyor belts, but there are few studies on energy-saving and wear-resistant low-smoke, halogen-free, flame-retardant steel cord conveyor belts.
