Abstract

The invention discloses a wear-resistant flame-retardant conveying belt and a preparation process thereof. The wear-resistant flame-retardant conveying belt comprises a cover glue, an adhesive intermediate glue and a framework material, wherein the cover glue comprises an upper cover glue and a lower cover glue; the framework material is a steel wire rope or a flame-retardant polyester fabric; thecover glue comprises the following components: a matrix rubber, sulfur, flame retardant, 10-15 parts of stearic acid, an anti-aging agent, a vulcanization accelerator, a reinforcing filler, paraffinwax, metal oxides, a wear-resistant filler and a dispersing agent. A preparation process of the wear-resistant flame-retardant conveying belt comprises the steps of S1, preparation of the cover glue:(1) preliminary plastication and (2) mixed granulation; S2, preparation of the adhesive intermediate glue: I, preliminary plastication; II, stirring and mixing; III, grinding and defoaming; S3, impregnation and plasticizing of an aggregate material; and S4, extrusion and gluing of the cover glue. The wear-resistant flame-retardant conveying belt disclosed by the invention has the advantages of good wear resistance and excellent flame-retardant effect; in addition, the preparation method disclosed by the invention has the advantages of simple process, low production cost and high work efficiency.

Description

technical field [0001] The invention relates to the technical field of conveyor belts, more specifically, it relates to a wear-resistant and flame-resistant conveyor belt and a preparation process thereof. Background technique [0002] Rubber conveyor belt is an important rubber product and an important means of transporting modern industrial materials and products. It is widely used in various sectors of the national economy such as coal mines, electric power, cement, steel, chemicals, and ports. The product is second only to tires. Improving the service life of the conveyor belt is the most important research direction for the conveyor belt industry to improve the quality, and it is also the most important problem that scientific and technological workers have been committed to solving. And among the factors affecting the service life of the conveyor belt at present, more than 95% are the wear and tear of the cover rubber of the conveyor belt, which exposes the skeleton m...
