AI Technical Summary

Technical Problem

PE protective film is easily scratched or worn when it comes into contact with rough objects, resulting in surface damage and loss of its protective function.

Method used

It adopts a multi-layer structure design, including a surface layer, an intermediate layer, a core layer, an interface adhesive layer, a sun protection coating, and an anti-mildew coating. It utilizes a combination of high-density polyethylene, linear low-density polyethylene, polyolefin elastomer, and inorganic metal ion compound layers to enhance toughness and wear resistance, and to inhibit mold growth by reflecting ultraviolet rays through a scattering effect.

Benefits of technology

It significantly improves the protective film's impact resistance, tear resistance, and abrasion resistance, extends its service life, prevents the protected object from being damaged by ultraviolet rays and mold, and reduces health risks.

Abstract

This utility model discloses a high-toughness and wear-resistant composite PE protective film, relating to the field of PE protective film technology. It includes a surface layer, an intermediate layer fixedly installed at the bottom of the surface layer, an anti-mildew coating fixedly installed at the bottom of the intermediate layer, a core layer on the bottom surface of the anti-mildew coating, an interface adhesive layer on the top of the core layer, and a sun-protective coating on the top of the surface layer. The interface adhesive layer is a uniform and continuous thin film. The sun-protective coating utilizes a scattering effect to reflect ultraviolet rays back into the environment, reducing the energy of ultraviolet rays penetrating to the protected object, preventing the protective film from losing elasticity and hardening due to ultraviolet radiation, maintaining its sealing performance, and extending its overall service life. The inorganic metal ion compound layer of the anti-mildew coating inhibits the catalytic action of enzymes, preventing mold from synthesizing proteins and energy, preventing damage to the protected object due to mold metabolism, reducing odor and health risks, and protecting the condition of the protective film and the protected object from the perspective of microbial influence.
