Problems solved by technology

[0004] As mentioned above, the covering rubber layer of the existing flame-retardant tape can play flame-retardant and antistatic effects to a certain extent, but the performance of the rubber layer is low, and the wear resistance, tensile performance, and flame-retardant properties of the rubber material are relatively low. And other comprehensive properties are far below the requirements of the MT668-1997 standard, especially when there are technical problems such as sticking to the car during the rubber mixing process, because there is no corresponding method to solve it, the physical properties of the mixed rubber have to be reduced to meet the production process. Require
In addition, since the existing flame-retardant adhesive layer does not contain solid flame-retardant lubricants, the flame-retardant tape cannot effectively reduce the friction force during the friction drum test, resulting in the temperature of the friction drum exceeding the target.

Abstract

The invention relates to a flame-proof steel belt conveyor, which is based on the adhesive property between the flame-proof layer and the steel wire to improve the flame-proof, anti-abrasion, and conducting static electricity property of glue material by adjusting the proportion of raw material, adding flame-proof lubricant and using new conducting carbon black, to improve the whole property of invention and meet the standard of MT668-1997. Said invention mainly comprises steel wires and flame-proof covering glue layer. Wherein, the formulation of flame-proof covering glue layer comprises: neoprene in 80-100 deals; zinc oxide in 4-20 deals; accelerant (as melaniline) in 2-8 deals; conducting carbon black in 4-15 deals; solid flame-proof agent (as antimony oxide) in 20-59 deals; liquid flame-proof agent (as triaryl phosphate) in 5-20 deals; white carbon black in 5-20 deals; and solid frame-proof lubricant MB-202 in 3-8 deals.

Description

technical field [0001] The invention is a new type of flame-retardant steel cord conveyor belt, in particular, it is mainly aimed at the improved design of the formula of the flame-retardant covering rubber layer of the conveyor belt. Background technique [0002] At present, in various coal mine enterprises, flame-retardant steel cord conveyor belts are mostly used in long-distance transportation in order to improve safety. Especially when working underground in coal mines, it is required to ensure flame retardant safety, and the conveyor belt used must have a relatively high flame retardant performance. [0003] The flame-retardant covering rubber layer of the existing flame-retardant steel cord conveyor belt is generally made of rubber, vulcanizing agent, anti-aging agent, stabilizer, flame retardant, antistatic agent and other materials. After cold pressing and bonding with the steel wire rope, a flame-retardant conveyor belt with upper and lower flame-retardant coverin...
