Abstract

The invention provides a whole-core antiflaming conveyer belt with a transition layer, comprising skeleton material, the transition layer and a covering layer, wherein the skeleton material is a solid entirety which is formed by impregnating and plastifying the whole belt core of textile, the transition layer is antiflaming thermoplastic elastomer, and the covering layer is antiflaming anti-static vulcanized rubber composite. The production method comprises the following steps: two extruders bond the transition layer with the skeleton material, and then the two extruders bond the covering layer with the transition layer. Because the transition layer of the thermoplastic elastomer is added between the whole belt core and the covering layer, the covering layer is tightly bonded with the belt core by the transition layer so as to effectively solve the problems of delaminating and foaming for the rubber surface in the prior art; meanwhile, the thickness of the whole covering glue formed by the covering layer and the transition layer is 6 mm, which is 4 times the prior art, thus prolonging the service life of the antiflaming belt; and in addition, because of the thermoplastic elastomer, the technology of extrusion shaping and dynamic vulcanization can be adopted to improve production efficiency and lower energy consumption.

Description

technical field

[0001] The invention relates to a flame-retardant conveyor belt for coal mines, in particular to a fabric whole-core flame-retardant conveyor belt and a production method thereof. Background technique

[0002] The whole core flame retardant conveyor belt is currently the main tool for coal mine transportation underground. According to MT914-2008 "Coal Mine Fabric Whole Core Flame Retardant Conveyor Belt", there are two types of whole core flame retardant conveyor belt: one is plastic whole core Flame-retardant conveyor belt, referred to as PVC type, is made of the whole belt core dipped in plastic and then coated with a layer of polyvinyl chloride resin on the surface. Its advantages are simple process, low cost, high production efficiency, and flame-retardant performance. Good, but the disadvantages are easy slipping, poor trough formation, small conveying inclination, and low conveying efficiency; the other is the rubber-faced whole-core flame-retardant con...
