AI Technical Summary

Problems solved by technology

The traditional polyester canvas is coated with PVC resin on both sides. The main disadvantages are: high density and bulky, low strength, non-wear-resistant, brittle and aging, air leakage and water permeability, and inconvenient processing and operation; low tensile and tear strength, low peel strength, The weather resistance and low temperature resistance and dimensional stability are poor, and the application field is greatly limited. It cannot meet the needs of light-weight and high-strength coating materials in special fields, and there are also problems in processing environmental protection and safety.

Abstract

A high-performance fiber reinforced film composite material comprises a bonded fabric and a resin coating layer on the surface of the boned fabric and is characterized in that the boned fabric takes high-strength fiber with the yarn count of 200-600D as warp or weft; the weaved warp and weft density is 22*22-27*27; the boned organization structure is a plain weave or a square grid organization or bi-axial warp-knitting (the warp and weft density is 18*18-18*20) structural fabric; the resin coating layer is characterized in that at least one surface out of two surfaces of the boned fabric is coated by the resin layer with a combination process of clearance coating and transferring coating; the resin layer comprises 85-90 parts of thermoplastic resin, 1-5 parts of nano-inorganic additive and 5-10 parts of organic modifier. The composite material is characterized in that the surface density is less than or equal to 280g / m<2>, the warp and weft elongation breaking strength is 750-1000N / cm, the warp and weft incision tearing strength is 750-850N and the elongation at break is less than or equal to 5%; furthermore, the composite material has the advantages of good weather-resistance and temperature-resistance and self-cleaning performance, strong flexibility and anti-fatigue, and being capable of high-frequency heat sealing; and the peeling strength (fabric / adhesive) is more than or equal to 2500N / m.

Description

1. Technical field [0001] The invention relates to a high-performance synthetic fiber (high-strength, high-modulus, low-shrinkage industrial filament, hereinafter referred to as high-strength fiber) reinforced membrane composite material, that is, one or more high-strength fiber filaments are used to weave a skeleton structure, and after pretreatment, shaping, Coating, compounding and other processes to process high-performance composite materials. 2. Background technology [0002] The research and industrialization of high-performance fibers and functional polymers has greatly promoted the development of the new material industry. Fiber-reinforced composite materials are key materials that are urgently needed in the process of industrial upgrading in my country, and there is a broad market demand.
