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.
