Abstract

The invention discloses a fabric laminated flame-retardant conveyor belt for coal mines. The fabric laminated flame-retardant conveyor belt for coal mines is characterized in that the framework material, the cover adhesive formulation and the adhesive sticker formulation are improved and a flame-retardant fabric layer having certain flame retardant property is taken as the framework material, and therefore, the safety performance index is satisfied, and the problems of easy deflection and large elongation of an integer core belt. Besides, the rubber-plastic CPE (Chlorinated Polyethylene) is introduced into the cover adhesive formulation so that the flowing property of the cover adhesive at high temperatures can be improved; a flame-retardant lubricant MB-202 is added so that the temperature rise rate can be reduced, and the friction temperature not exceeding 325 DEG C of a roller is guaranteed. In the adhesive sticker formulation, a plurality of adhesives are combined so that the adhesive strength can be improved, and moreover, the scaling problem is solved.

Description

technical field [0001] The invention relates to the technical field of rubber conveyor belt products, in particular to a laminated flame-retardant conveyor belt, and more specifically, to a flame-retardant and antistatic conveyor belt meeting the requirements for underground use in coal mines. Background technique [0002] Underground coal mines have very high requirements on the safety performance of conveyor belts, and conveyor belts must have high flame retardant, antistatic and other characteristics before they can run in mines. In the 1980s, my country began to promote PVC and PVG whole-core flame-retardant belts. This kind of conveyor belt uses the flame-retardant properties of PVC to coat the braided fibers to achieve flame-retardant purposes. [0003] Due to the lack of adhesion of PVC, it is impossible to realize the bonding between layers of flame-retardant cloth layers by itself or general modification, so this kind of tape can only be woven into a whole skeleton ...
