Thermoplastic elastomer surface unitary-core flame-resistant conveying belt and manufacturing method thereof

Abstract

The invention discloses a thermal-plastic elastic-face whole core fire resistant conveyer belt and the preparing method. The conveyer belt comprises skeleton and covering glue out of the skeleton, which is characterized in that said covering glue adopts NBR powder and PVC; thermal-plastic flame retardant and antistatic elastic body is prepared by mixing, granulating and dynamically vulcanizing with extruder; the thermal-plastic flame retardant and antistatic elastic body is bonded with fabric integral belt core together in thermal status after dipping and plasticizing. The invention leaves out refining glue, calendaring and plate vulcanization so on. Producing efficiency and product quality can be improved greatly.

Description

Technical field

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

[0002] Conveyor belt is the main tool for transporting coal underground in coal mines. Because traditional rubber conveyor belts are flammable and cannot meet the requirements of underground flame retardancy and antistatic, coal mines generally use fabric whole-core flame-retardant conveyor belts. At present, there are mainly two types of whole-core flame-retardant conveyor belts: one is an all-plastic whole-core flame-retardant belt, which has the advantages of simple production process, less equipment investment, and good flame-retardant performance. The surface is slippery and the lifting angle is small; the other is the rubber-plastic whole-core flame-retardant belt, which is made by adhering a layer of rubber...
