Problems solved by technology

[0006] Although the existing environmentally friendly steel cord flame-retardant conveyor belt for coal mines solves the problem that a large amount of toxic and harmful gases and smog will be generated when the existing steel cord flame-retardant conveyor belt burns, but because of the lack of reinforcing components in the conveyor belt, the The toughness and strength of the conveyor belt are poor, and it cannot achieve high mechanical properties while meeting the flame retardant properties.

Abstract

The invention discloses a flame-retardant high-strength conveyor belt and a preparation process thereof. The flame-retardant high-strength conveyor belt comprises a covering adhesive, a bonded intermediate adhesive and a framework material, wherein the covering adhesive comprises an upper covering adhesive and a lower covering adhesive, and the framework material is steel wire ropes or flame-retardant polyester fabrics. The preparation method includes the following steps: S1. preparing covering glue: (1) preliminarily plasticating; (2) mixing and granulating; S2. preparing the bonded intermediate adhesive: I. primary plastication; II. stirring and mixing; III. grinding and defoaming; S3. gum dipping and plasticizing of aggregate materials; S4. extruding and bonding the covering adhesive. The flame-retardant high-strength conveyor belt has the advantages of good flame retardant performance, safety, environmental protection and high mechanical strength; and in addition, the preparation method has the advantages of simple process, low production cost and high working efficiency.

Description

technical field [0001] The invention relates to the technical field of conveyor belts, more specifically, it relates to a flame-retardant high-strength conveyor belt and a preparation process thereof. Background technique [0002] 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, and the discharge of slag in industrial and mining enterprises. As early as the early 1950s, my country introduced conveyor belt technology based on natural (NR) rubber raw materials from the former Soviet Union. Later, with the advancement of science and technology and the gradual advancement of modernization in our country, the rubber conveyor belt technology research and product development have undergone tremendous changes, and ...
