Dipped canvas fabric structure in three-dimensional structure for heavy-duty conveyor belt and production process thereof

Abstract

The invention discloses a three-dimensional structure dipped canvas fabric structure for a heavy-duty conveyor belt and a production process thereof. The structure of the dipped fabric is: the upper layer and the bottom layer are plain warp yarns (1) and the weft yarns interwoven with the ground warp yarns (2), the middle layer is straight warp yarns (3) with a straight warp structure, and the binding warp yarns (4) Connecting the weft yarn (2), the upper layer, the middle layer, the bottom layer and the binding warp yarn form a three-dimensional three-dimensional structure. The production process of the present invention comprises: the upper machine weaving process of the fabric: adopting double warp beams to send the warp cloth; dipping formula and deployment process: the dipping solution is the aqueous solution of RF resin generated by the polycondensation reaction of resorcinol and formaldehyde and The mixture of VP latex (L) has a total solid content of 18-22%, a pH value of 9-11, and a ratio of RF to L of 1:5-1:7. The three-dimensional structure polyester dipped canvas of the present invention is especially suitable for the production of heavy-duty rubber conveyor belts, and has the characteristics of tear resistance, puncture resistance and impact resistance.

Description

technical field [0001] The invention relates to a framework material for a heavy-duty rubber conveyor belt and a production process thereof, belonging to the technical field of industrial fabrics. Background technique [0002] Polyester industrial textiles use polyester industrial yarn as the main raw material. Polyester industrial yarn has become the main raw material of industrial textiles due to its high strength, high modulus, high temperature resistance and other excellent properties. Mechanical rubber products-rubber conveyor belts, transmission belts 1. The skeleton material necessary for rubber hoses has been basically polyesterized, and polyester dipped canvas has shown its strong advantages in heavy-duty rubber conveyor belts. [0003] In recent years, with the improvement of environmental protection requirements, the improvement of automation and conveying capacity, and the further extension of conveying distance, the rubber conveyor belt has put forward higher re...
