Problems solved by technology

[0004] At present, the commercially available cut-resistant conveyor belts mainly use high-modulus fiber materials or steel mesh as the skeleton material, but the covering rubber that carries the material itself has no obvious cut-resistant performance.

Abstract

The invention relates to cutting-resistant conveying belt covering glue and a preparation method thereof and belongs to the technical field of conveying belts. The preparation method includes: adding nano-clay butylbenzene masterbatch and natural rubber into an internal mixer, sequentially adding zinc oxide, stearic acid, antiager, short fiber, reinforcing agent and softener, and mixing before stopping to obtain first-stage mixing glue; adding sulphur and promoter into the first-stage mixing glue for second-stage mixing; vulcanizing to obtain the cutting-resistant conveying belt covering glue. The nano-clay utylbenzene masterbatch and the natural rubber are adopted as a rubber matrix, so that modulus, elasticity and aging resistance of the rubber matrix are taken into consideration; the short fiber is adopted to enhance modulus of a rubber system and absorb energy generated by colloid cutting; highly-combined styrene resin is adopted to increase benzene ring content and increase modulus of the rubber system; soft carbon black and hard carbon black are adopted, so that reinforcing performance and processability are integrated.

Description

technical field [0001] The invention relates to a cutting-resistant conveyor belt covering glue and a preparation method thereof. The prepared product has good cutting resistance, is used in conveyor belt products, and can be widely used in coal mines, metal mines and other working conditions, and belongs to the conveyor belt technology field. Background technique [0002] Conveyor belts are widely used in cement, mines, ports and other industries, and the working conditions of the conveyor belt and the characteristics of the transported materials determine the characteristics that the conveyor belt should have. For example, the cement industry generally needs high temperature resistant conveyor belts, and the coal mining industry needs flame retardant conveyor belts. [0003] It is reported that when foreign mines transport bulky, sharp-edged materials, there is a height difference of more than 2m between the material and the horizontally running conveyor belt, causing the...
