technical field

The invention relates to the technical field of conveyor belt materials, in particular to a high-friction conveyor belt material and a preparation method thereof.

Background technique

Rubber conveyor belt is a traditional rubber product with a wide range of uses. It is mainly used for the transfer and transportation of various materials, such as the transportation of underground materials in the mining industry and the loading and unloading of the ground, the loading and unloading of dock materials, the discharge of slag in industrial and mining enterprises, and the sorting of postal express delivery. As an uninterrupted load transfer carrier, in the face of various working environments, the conveyor belt is required to have excellent wear resistance, mechanical mechanics and performance stability.

High-friction conveyor belt is a relatively common conveyor belt, which is widely used in automatic sorting conveyor lines for postal letters and automatic scanning and resolution conveyor lines for small commodity packaging barcodes in food, tobacco and other industries. Due to the high speed of conveying, the conveyed items need to be stable, which makes the high friction conveyor belt have higher requirements on wear resistance and mechanical properties. The wear resistance and mechanical properties of traditional ordinary rubber conveyor belts cannot meet the above requirements. The existing high-friction conveyor belts still have more or less defects of poor environmental protection, short service life, insufficient aging resistance and performance stability, and further improvement in mechanical properties and wear resistance.

In order to solve the above problems, the patent CN1313530C discloses a high-friction conveyor belt material, including base materials, elastomers, plasticizers, stabilizers, and reinforcing fillers. The base materials are PVC paste resin and PVC mixed resin, The plasticizer includes XNBR rubber plasticizer. The invention uses nitrile rubber and XNBR liquid rubber plasticizer to blend and modify the high-friction conveyor belt material produced by ordinary PVC resin. Compared with resin, at the same hardness, although its tensile strength is not as good as thermoplastic polyurethane, it is higher than other thermoplastic elastomers; compression set and thermal deformation rate are lower than soft PVC, which are close to rubber and have improved resilience; The heat and cold resistance is better than that of soft PVC, the shape retention at high temperature is good, and the dependence of hardness on temperature is also smaller than that of soft PVC; its bending fatigue is better than that of general soft PVC, and it has good surface properties, adhesion, Paintability, abrasion resistance and matting. However, its environmental protection is not good, its wear resistance and mechanical properties need to be further improved, and its performance stability needs to be further improved due to the compatibility problem between the components.

Therefore, the development of a high-friction conveyor belt material with good environmental protection, long service life, sufficient aging resistance and performance stability, excellent mechanical properties and wear resistance meets market demand, has extensive market value and application prospects, and is beneficial to It is of great significance to promote the development of the conveyor belt field.
