High-strength anti-ageing skid-proof conveying belt

Abstract

The invention discloses a high-strength anti-ageing skid-proof conveying belt. The high-strength anti-ageing skid-proof conveying belt is characterized by being prepared from the following raw materials in parts by weight: 30-40 parts of natural rubber, 15-20 parts of nitrile rubber, 2-3 parts of nanometer-grade active argil, 8-15 parts of polyvinyl chloride resin, 2-3 parts of a VP adhesive, 1.5-2 parts of a plasticizer, 2-4 parts of calcium carbonate, 2-4 parts of stearic acid, 6-10 parts of carbon black N754, 6-8 parts of white carbon black, 1-2 parts of coumarone, 4-5 parts of aromatic hydrocarbon oil, 1-1.2 parts of engine oil, 4-5 parts of sulfur and 1-2 parts of an anti-ageing agent. The high-strength anti-ageing skid-proof conveying belt disclosed by the invention is improved in appearance quality, and a damaged part is flatly replenished with the adhesive, so that the adhesion between frame canvases of the conveying belt maintains the properties of an original common heat-resisting conveying belt adhesive, the thermal oxidization and ageing resistance of the adhesive is enhanced; the performances such as tensile strength, layer-layer adhesion strength, heat resistance and wear resistance are all improved; the high-strength anti-ageing skid-proof conveying belt can be applied to large machineries for coal mines, stone materials and the like.

Description

technical field [0001] The invention belongs to the technical field of conveyor belt materials, and in particular relates to a high-strength anti-aging and anti-slip conveyor belt. Background technique [0002] The non-slip conveyor belt is carefully processed by polyester-cotton interweaving, EP, PP canvas through calendering, molding and vulcanization. The main feature is anti-slip, the anti-slip function is better, and the anti-slip conveyor belt is durable and has a long service life. There are mainly ordinary herringbone, convex herringbone, horizontal grid, round nail and other types. This product is suitable for conveying bulk, granular, bagged and powdered materials at a large inclination angle, such as coal, charcoal, wood, sand, cement bags, grain and other materials. Main application industries: tobacco, logistics, packaging, printing, food, wood, etc. The non-slip conveyor belt is used for conveying materials with a conveying angle of more than 17°. [0003] ...

Problems solved by technology

However, the current working conditions of domestic production enterprises cannot meet such high requirements, so problems such as delamination and cross-cutting of conveyor belts caused by long-term high-temperature operation often occur
