Problems solved by technology

[0003] There are many types of composite membranes on the market, but it is difficult to have high-strength, waterproof, and breathable physical and mechanical properties at the same time, and the traditional composite membranes do not have anti-static capabilities, which affects later use. Therefore, a High-strength waterproof and breathable composite membrane is very meaningful

Abstract

The invention discloses a high-strength waterproof breathable composite film. The composite film comprises a composite film main body, polymer film layers, a fiber reinforcing layer, a spinning wovenfabric layer and a PU film; the polymer film layers are arranged in the middle of the composite film main body; the fiber reinforcing layer is connected to the outer walls of the polymer film layers through an adhesive in a bonding mode; the spinning woven fabric layer is connected to the outer wall of the top of the polymer film layers in an attached mode; and the PU film is connected to the outer wall of the bottom of the polymer film layers through PU glue in a composite mode; the spinning woven fabric layer is formed by weaving combined warp yarns and cotton fiber weft yarns in a staggeredmanner, polyester fiber yarns being arranged in the combined warp yarns. Due to the arrangement of nanoparticles in the composite film, the composite film is rich in pores and has a very good breathable effect; due to the arrangement of the spinning woven layer, the composite film has good anti-pollution capacity; and due to the arrangement of the cotton fiber weft yarns, the polyester fiber yarns and polyamide fiber threads in the fiber reinforcing layer and the combined warp yarns, the composite film has higher strength.

Description

technical field [0001] The invention relates to the technical field of composite membranes, in particular to a high-strength waterproof and breathable composite membrane. Background technique [0002] The material of the composite membrane includes any possible combination of materials, such as a ceramic membrane on a metal oxide or an aromatic polyamide film on a polysulfone microporous membrane, and the flat membrane or roll membrane must be made of non-woven fabrics. Reinforced to support the pressure resistance of microporous membranes, while hollow fiber membranes are not required; the preparation methods are divided into four categories: (1) Lamination method, first prepare a very thin dense homogeneous membrane, and then laminated on the microporous support (2) Dip coating method, the polymer solution is dip-coated on the microporous membrane, and then dried, and the active monomer or prepolymer solution can also be dip-coated on the microporous membrane, and heat or ...
