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

Abstract

The invention discloses a dipped canvas fabric structure in a three-dimensional structure for a heavy-duty conveyor belt and a production process thereof. The dipped fabric structure is characterized in that an upper layer and a bottom layer adopt ground-facing warps (1) in the plain weave structure and weft (2) interwoven with the ground-facing warp, a straight warp (3) in the straight warp structure is utilized as an intermediate layer, a bundling warp (4) is connected with the weft (2), and the upper layer, the intermediate layer, the bottom layer and the bundling warp form the three-dimensional structure. The production process comprises the following processes: the process of weaving a fabric on a machine: adopting double warp shafts to send a warp woven cloth; and the process of stipulating a dipping formula and preparing, wherein a dipping solution is a mixture of an RF (resorcinol-formaldehyde) resin water solution generated by virtue of condensation polymerization of hydroxyphenol and formaldehyde and VP (vinyl pyridine) latex (L), the total content of solids is 18-22%, the pH value is 9-11, and the ratio of the RF to the L is (1:5)-(1:7). Polyester dipped canvas in the three-dimensional structure is especially applicable to production of the 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...
