Embodiment 1

[0023] It should be noted that the sources and trade names of the materials used, as well as those whose components must be listed, are all indicated when they appear for the first time, and the same materials used thereafter have the same contents as those indicated for the first time unless otherwise specified.

[0024] The preparation of embodiment 1 mildew-proof antibacterial adhesive tape, its steps are as follows successively:

[0025] 1) Preparation of antibacterial film layer. In Example 1, the imidazole thiophene mixture was used as the antibacterial agent, and PEVA was used as the base material of the film for mixing and preparation. The imidazole-thiophene mixture is formed by physically mixing imidazole and thiophene at a weight ratio of 1:1. Firstly, the imidazole thiophene mixture is uniformly mixed with PEVA, and the resulting product is passed through an extruder to produce a PEVA film with anti-mold and antibacterial effects, that is, an antibacterial film la...

Embodiment 2

[0029] The preparation of embodiment 2 mildew-proof and antibacterial adhesive tapes, its steps are as follows successively:

[0030] a) Preparation of antibacterial coating. In Example 2, imidazole thiophene mixture and fumed silica were used as antibacterial agent, ethyl acetate was used as co-solvent, and PET was used as plastic substrate. Disperse the mixture of imidazolethiophene and gas-phase silica in ethyl acetate, and disperse and mix evenly under a high-speed mixer. Be prepared into antibacterial coating, its proportioning ratio is as shown in the following table 1:

[0037] The preparation of embodiment 3 mildew-proof and antibacterial adhesive tapes, its steps are as follows successively:

[0038] a) Preparation of antibacterial coating. In Example 3, imidazole thiophene mixture and fumed silica were used as antibacterial agent, ethyl acetate was used as co-solvent, and PET was used as plastic substrate. Disperse the mixture of imidazolethiophene and gas-phase silica in ethyl acetate, and disperse and mix evenly under a high-speed mixer.

Abstract

The invention discloses a mildewproof antibacterial adhesive tape and a preparation method thereof. The mildewproof antibacterial adhesive tape comprises an antibacterial film layer and an adhesive layer, wherein the adhesive layer is attached to one surface of the antibacterial film layer; the antibacterial film layer comprises an antibacterial agent and a plastic base material; the antibacterial agent comprises an imidazole and thiofuran mixture; the antibacterial film layer is prepared by mixing the antibacterial agent and the plastic base material or prepared by coating the antibacterial agent on one surface of a plastic film made from the plastic base material; the adhesive layer is attached to the other surface of the plastic film. The preparation method sequentially comprises the following steps of (1) mixing the antibacterial agent and the plastic base material, and preparing the antibacterial film layer from the mixture through an extruder; (2) coating one surface of the antibacterial film layer with glue, and drying to form the adhesive layer. The mildewproof antibacterial adhesive tape disclosed by the invention can achieve the mildewproof antibacterial effect by tearing a segment of a product and adhering on a touched article.

Description

technical field [0001] The invention relates to an anti-mildew and anti-bacterial adhesive tape and a preparation method thereof. Background technique [0002] With the continuous improvement of human science and technology, people in both developing countries and developed countries have higher and higher requirements for hygiene, especially in some special environments, people are paying more and more attention. The following examples The technical background of this invention will be explained. [0003] The medical industry, the door handrail of the operating room in the hospital and other places where the staff may touch. Before the doctor prepares for the operation, the doctor and the surgical team must wear special surgical gloves and other equipment, and disinfect them before entering the operating room to operate on the patient. The work done by the doctors and the surgical team is to prevent bacteria and other microorganisms from being brought into the operating r...
