Problems solved by technology

[0004] The purpose of the present invention is to provide a preparation process for a 3D pattern anti-leakage and high-breathability membrane, to solve the problem of using the existing anti-leakage and high-breathability membrane proposed in the above-mentioned background technology, because most of them adopt the common The steel roller and pressure roller are used for calendering, so that the calendered pattern on the breathable film is not obvious enough, so that the pressed pattern lacks a certain sense of clarity, which leads to the problem that the light refracted by the light is not saturated enough, and the pattern lacks a three-dimensional feeling.

Abstract

The invention discloses a preparation process of a 3D pattern anti-leakage high-breathability film. The preparation process comprises the steps of material selection, material blending, moisture absorption and drying, shearing and mulling, melt extrusion, chilling and sheet casting, online thickness measurement, multi-stage stretching, 3D cooling and embossing, corona surface roughening treatment, rolling and product slitting. A material comprises breathable particles with constant deformation performance, breathable particles with a good tensile property, high-strength polyethylene, polyimide resin, epoxy resin, high-strength and puncture-resistant breathable particles containing nanoscale calcium carbonate and antistatic particles. The 3D embossing steel roller with a special effect is manufactured by arranging the 3D embossing steel roller and the specific rubber compression roller and utilizing the principle that light rays refract different patterns at different angles, a specific engraving process is verified and developed, and an applicable manufacturing process is formulated in cooperation with pattern requirements, so that a product can better highlight the 3D effect after being formed, and is more attractive to consumers.

Description

technical field [0001] The invention belongs to the technical field of gas-permeable membrane manufacturing, and in particular relates to a preparation process of a 3D pattern anti-leakage and high-gas-permeability membrane. Background technique [0002] In the textile fabric industry, the breathable membrane is actually a waterproof and moisture-permeable membrane, made of polymer elastomer TPU as the main material, which has good elasticity and high strength. In terms of waterproof properties, although the thickness is extremely thin, it has physical properties unmatched by other materials. It uses high-tech technology to introduce hydrophilic groups into the material so that the film has excellent moisture permeability in addition to high water resistance. A breakthrough in function, combined with the bonding processing technology of the textile industry, greatly enhances the added value of textiles, and has been widely used in snow coats, windbreakers, cold jackets, glov...
