Aging-resistant and wear-resistant light conveying belt and preparation method thereof

Abstract

The invention discloses an aging-resistant and wear-resistant light conveying belt which comprises aging-resistant and wear-resistant glue, and the aging-resistant and wear-resistant glue comprises the following components in parts by weight: 100 parts of PVC resin, 30-40 parts of a plasticizer, 20-30 parts of an aging-resistant modifier, 1-2 parts of an organic silicon wear-resistant agent, 4 parts of a heat stabilizer and 3 parts of color paste, Wherein the polymerization degree of the PVC resin is 1800-2200, and the K value of the PVC resin is 60-85. The 1% definite elongation strength of the conveying belt reaches 45 N / mm or above, the elongation is small, the specific gravity of the adhesive layer is low, the conveying belt is made of a thermoplastic material, the aging phenomena of cracking, falling and the like are not likely to happen even if the conveying belt is used in a high-temperature environment, the abrasion resistance is good, and the service life is long.

Description

technical field [0001] The invention relates to a conveyor belt, in particular to an aging and wear-resistant light conveyor belt and a preparation method thereof. Background technique [0002] Conveyor belt, also known as conveyor belt, is a product used to carry and transport materials. It is widely used in various industries and can greatly improve production efficiency. Most of the covering rubber materials of existing conveyor belts are based on natural rubber (NR), neoprene rubber (CR), butadiene rubber (BR), isoprene rubber (IR), and styrene-butadiene rubber (SBR), and the skeleton material is nylon , Polyester canvas mainly. However, the weight of these rubber conveyor belts is relatively large, resulting in high energy consumption for conveying. For example, the rubber conveyor belt used for conveying kiln raw materials in the ceramic and stone industry generally has 4 or 5 layers of canvas skeleton, the thickness of the bottom rubber is 1.0-1.5mm, the thickness o...

Problems solved by technology

Secondly, the aging resistance and wear resistance of these rubber conveyor belts are poor, and the service life is short. Generally, the rubber layer will crack, fall off and be severely worn after being transported in a ceramic kiln for about 6 months. High, and the shedding rubber will pollute the product and the environment

In addition, these rubber conveyor belts have a large elongation rate, are easily stretched during use, and require frequent maintenance, hindering production
