Abstract

The invention discloses coated cloth with high strength for railway wagon tarp and making method thereof. The coating cloth includes high-strength and low-shrinkage terylene continuous filament yarn base cloth and PVC coating agent coated on the base cloth. The method comprises employing 800D-1300D high-strength and low-shrinkage terylene continuous filament yarns as warp yarn and weft yarn, or warp yarn, weft yarn and reinforced rib to make the base cloth; making base material and facing material of the PVC coating agent by PVC paste resin, plasticizer, temperature depressing plasticizer, stabilizer, flame retardant, stuffing, aging resistance agent, milew-proof agent and dye; evenly coating the base material on two sides of the base cloth with vertical coating method, and dyeing; coating one layer of facing material on vertically-coated two sides of the cloth by horizontal coating method, and tentering, plasticizing, drying, then performing surface treatment to make the coated cloth with high strength special for railway wagon tarp. The product of the invention has advantages of good stability, high strength, light weight, aging resistance, water-proof, dirt-proof, milew-proof, flame-proof, splite-proof performances, good weathering resistance and stripping performance. The method of the invention is simple, use and operation are convenient.

Description

1. Technical field: [0001] The invention relates to a high-strength chemical fiber coated cloth and a manufacturing method thereof, in particular to a high-strength chemical fiber coated cloth for railway wagon tarpaulins and a manufacturing method thereof. 2. Background technology: [0002] At present, my country's railway freight car tarpaulin is made of polyester staple fiber fabric as the base cloth, which is made of double-sided artificial leather after plastic coating. There are disadvantages such as low strength, heavy weight, rough surface, narrow surface width, easy aging, short service life, poor flame retardancy, insufficient softness, warp and weft breaking tension and elongation rate are not up to standard, etc. 3. Contents of the invention: [0003] The present invention solves the above-mentioned problems existing in the prior art, and provides a high-strength coated cloth for railway wagon tarpaulin with high strength, light weight, tear resistance, long se...
