Wear-resistant heat-resistant conveyer belt coated rubber

Abstract

The invention discloses wear-resistant heat-resistant conveyer belt coated rubber. The wear-resistant heat-resistant conveyer belt coated rubber comprises, by weight, 100 parts of nanometer composite masterbatch, 18-22 parts of a mixture comprising carbon black N234 and carbon black N115 according to a weight ratio of 1: 1, 5-7 parts of chlorosulfonated polyethylene with chlorine content of 25-30%, 2-3 parts of stearic acid, 2-3 parts of an antiager, 1.2-1.5 parts of a solid silane coupling agent SI-69, 3-5 parts of C9 petroleum resin, 0.6-0.8 parts of an scorch retarder CTP, 0.8-1 part of N-(4-phenylamino)phenyl)maleimide and 0.5-0.7 parts of 4,4'-dithiodimorpholine. The conveyer belt prepared from the wear-resistant heat-resistant conveyer belt coated rubber has good tensile strength, temperature resistance and wear resistance. The wear-resistant heat-resistant conveyer belt coated rubber improves thermo-oxidative aging resistance of the conveyer belt, prevents delaminating, greatly improves a conveyer belt service life and has a wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of conveyor belt rubber production, and in particular relates to an anti-wear and heat-resistant conveyor belt glue. Background technique [0002] Gluing is to use a calender to press and paste the rubber on the cord or canvas to make a rubber cord or a glued canvas, which is used to produce tires, tapes, and tape products. Adhesive fabrics are usually glued, glued or dipped first and then covered with glue. Using a four-roller calender to apply glue on both sides of the dipped cord at one time is a highly efficient method for manufacturing tires. The number of fillers and plasticizers in the rubber for pasting should be more, and the plasticity of the hot-mixed rubber should be higher and consistent. When gluing, the two rollers of the calender rotate at the same speed, but when gluing, the linear speeds of the two rollers are not equal. [0003] The conveyor belt adopts high-performance additives of var...

AI Technical Summary

Problems solved by technology

When transporting materials with hard, irregular shapes and sharp edges, although the skeleton material is intact, the covering rubber is severely worn, punctured and torn and cannot be used

At present, domestic manufacturers have not systematically tested and evaluated aspects such as cutting resistance, puncture resistance, flex fatigue resistance, crack growth resistance, and low temperature physical and mechanical properties.

Therefore, these reasons limit the application range and service life of long-distance conveyor belts.
