Formula of ultra-high molecular weight polyethylene canvas surface modified rubber cement for rubber conveying belt

Abstract

The invention relates to a formula of ultra-high molecular weight polyethylene canvas surface modified rubber cement for a rubber conveying belt. The formula comprises the following components in parts by weight: 100 parts of elastomer, 10-30 parts of functionalized polyethylene, 10-30 parts of carbon black, 0-5 parts of sulfur, 0-2 parts of accelerant, 1-5 parts of peroxide initiator, 2-4 parts of assistant crosslinker, 10-20 part of maleic anhydride modified polybutadiene, and 5-10 parts of polyisocyanate or polyisocyanates. The ultra-high molecular weight polyethylene canvas can be bonded with the rubber conveying belt through the adhesive cement prepared according to the formula, and the rubber conveying belt produced by adopting the ultra-high molecular weight polyethylene fiber impregnated canvas coated with the adhesive cement has the characteristics of small elongation, good impact resistance, tear resistance, energy conservation and high strength; a steel wire rope can be replaced, and upgrading and updating of conveying belt framework materials are achieved.

Description

technical field [0001] The invention belongs to the technical field of industrial textiles, in particular to a glue formulation for surface modification of high-modulus, low-elongation ultra-high molecular weight polyethylene dipped canvas for high-strength conveyor belts. Background technique [0002] Rubber conveyor belts have been widely used in the transportation of industrial bulk materials. For example, the ore mined by iron ore has to be crushed many times before being transported to the port for loading; Coal transportation in the process of processing; raw materials, fuels, etc. used in steel plants, power plants, cement plants, etc., in each processing stage, from loading to unloading, they need to be transported over long distances through conveyor belts. High-strength rubber conveyor belts It has become an important product in the national economy. [0003] Long-distance conveyor belts generally use steel wire ropes as stress-bearing components (skeleton materia...

AI Technical Summary

Problems solved by technology

However, the factor that restricts the practical application of ultra-high molecular weight polyethylene fibers on rubber conveyor belts is that ultra-high molecular weight polyethylene fibers are chemically inert and have extremely low reactivity with other materials, so they cannot be bonded with rubber.
