Although the originally used foam has good tensile strength, corrosion resistance, paint inertia resistance, ozone resistance, etc., the shrinkage rate of the rubber sheet is very large, and it will continue to shrink over time. , so that it limits its use in some high-precision fields
[0005] In the current production of conveyor belts, there are disadvantages such as low production efficiency, non-sticking of the composite interface, or reduced viscosity of the rubber material. As the main function of carrying loads and driving the conveyor belt, it is subjected to strong mechanical action during the operation of the conveyor belt. All from The design and actual damage analysis of the conveyor belt show that this part has a significant impact on the performance of the conveyor belt

Abstract
The invention discloses an anti-cracking pattern conveyor belt. The anti-cracking pattern conveyor belt is characterized in that the anti-cracking pattern conveyor belt comprises the following raw material components in parts by weight: 25 to 35 parts of isoprene rubber, 25 to 35 parts of EPDM, 10 to 20 parts of polypropylene, 5 to 6 parts of trichloroethylene, 3 to 5 parts of stearic acid, 6 to 8 parts of white factice, 8 to 12 parts of carbon black N375, 7 to 9 parts of silicon oxide, 2 to 3 parts of super tackifying agent HMT, 4 to 6 parts of sulfur, 1 to 2 parts of a foaming agent, 0.6 to 0.8 part of DCP, 3 to 4 parts of rosin resin, 0.5 to 0.8 part of modifier magnesium methacrylate and 4 to 5 parts of p-tert-Butylphenol formaldehyde resin. According to the anti-cracking pattern conveyor belt, the advantages of the rubber raw material such as good corrosion resistance and good oxidation resistance can be reserved, the shrinkage property, the cracking resistance and the stability can be greatly improved; on the premise that the process viscosity is not reduced, the production efficiency is improved, the process loss is reduced, and the application range in the field of high precision can be greatly enlarged.
Description
technical field [0001] The invention belongs to the technical field of rubber materials for conveyor belts, and in particular relates to a conveyor belt with an anti-crack pattern. Background technique [0002] The patterned conveyor belt is an inclined conveyor belt composed of a pattern-like covering rubber on the working surface, a flat covering rubber on the non-working surface and a belt core. There is a "herringbone" pattern on the belt surface that is higher than the belt body. The pattern can be open or closed. Each pattern can be divided into three types: high, medium and low. It is suitable for conveying powdery, granular and small materials with an inclination angle of ≤40 degrees, and can also convey bagged materials. [0003] During the use of the patterned conveyor belt, the running speed should generally not be greater than 2.5 m / s, and the material with large lumps and abrasiveness and the use of a fixed unloading device should use a low speed as much as pos...
