Problems solved by technology

Due to the particularity of the flexible cover, the use of traditional antibacterial coatings cannot guarantee the hardness of the surface, and is prone to failure. At the same time, it is easy to affect the light transmission performance. Therefore, it is necessary to achieve a limited sterilization function while maintaining the performance of the flexible cover. hard to have both

Abstract

The invention discloses an antibacterial flexible cover plate which sequentially comprises a transparent flexible base plate, a first hardened layer, a nanopore array antibacterial layer and a second hardened layer, wherein the transparent flexible base plate is one of a transparent polyimide film, polyacrylonitrile or PET; the first hardened layer and the second hardened layer are made of flexible cover plate hardening liquid; and the nanopore array antibacterial layer is prepared by filling a nanopore array with a resin material, and the resin material is prepared from urethane acrylate resin, amino / sulfydryl functional group-containing resin, a silver ion solution and a solvent with a swelling effect. The invention also discloses a preparation method. According to the invention, the nanopore array is adopted to fill the antibacterial material, so that the interlayer binding force is enhanced; due to the super-large specific surface area of the nanopores, the seepage rate of silver ions is increased, and meanwhile, the seepage speed is controlled; the main body resin of the antibacterial layer increases the light transmittance; and all the manufacturing procedures are achieved through a roll-to-roll and coating process, the process quality is stable, the investment of special equipment is reduced, the cost is reduced, and the product price is more competitive.

Description

technical field [0001] The invention relates to the technical field of flexible display screens, in particular to an antibacterial flexible cover plate and a preparation method thereof. Background technique [0002] Studies have shown that people touch their mobile phones as many as thousands of times a day, and the value varies from person to person. The average number is about 150 times a day, including touching their faces when making calls. Through random sampling research, microbiologists found that there are about 7,000 kinds of bacteria on the surface of mobile phones, including pathogenic bacteria such as Enterococcus and Pseudomonas. In addition to the adsorption of the mobile phone itself from the environment, most of these bacteria come from contact with human hands or faces, so microbiologists recommend that you clean your mobile phone with antibacterial wipes every day. This is difficult to do, and to make matters worse, the specific temperature conditions of m...
