Embodiment 1

[0029] The embodiment of the present invention provides a kind of preparation method of antibacterial plastic film, comprises the following steps:

[0030] S1. Take a certain amount of polypropylene pellets, fuse them with a certain amount of solvent, and prepare the polypropylene film base layer by casting process; adopt microporous polypropylene film as the base layer, the physical stability of this film, Good mechanical strength and air tightness, high transparency and gloss, tough and wear-resistant;

[0031] S2. After fully mixing a certain amount of polyethylene resin and ultra-fine Zanthoxylum bungeanum powder, melt it through an extruder, extrude it into a film, cool it down and shape it, and then stretch it to obtain a microporous film; Zanthoxylum bungeanum has antibacterial and insect-repelling properties. Efficacy, use ultra-fine pepper powder to fill and fuse polyethylene resin to form a micro-breathable air-porous film, so that the micro-porous film has good air ...

Embodiment 2

[0041] The difference between this embodiment and the above-mentioned embodiments is that the pretreatment of the polypropylene film base layer also includes the following methods: soak the polypropylene film base layer in the adhesive, take it out after soaking for a period of time, and dry the polypropylene film base layer; Soak the base layer of the polypropylene film in the antibacterial adhesive, take it out after soaking for a period of time, and dry the base layer of the polypropylene film to obtain the base layer of the polypropylene film with the surface of the antibacterial adhesive, which can make the adhesive fully absorb the antibacterial Bacteria adhesive adheres to the surface of the polypropylene film base layer to maintain the antibacterial properties and prolong the service life.

Embodiment 3

[0043] On the basis of the above embodiments, this embodiment provides an adhesive, the adhesive is a silicone adhesive, the preparation method of the silicone adhesive includes the following steps: weighing 65% of the silicone adhesive by mass percentage, 32% of hydroxy polysiloxane and 3% of silane coupling agent are fully mixed to obtain a silicone adhesive, and the organic silicon adhesive with exhaust and adsorption properties is prepared to facilitate the formation of exhaust channels, which is beneficial to Chinese herbal medicines. Bactericides are small molecules that exert a bactericidal effect.

Abstract

The invention provides a preparation method of a bacteria-resistant plastic film, and relates to the technical field of plastic film production. The preparation method comprises the following steps: S1, preparing a polypropylene film base layer by adopting a tape casting process; S2, fully mixing a certain amount of polyethylene resin and superfine pepper powder, extruding to form a film, and stretching to obtain a microporous film; S3, weighing a certain amount of acrylate, mica powder, ethanol, decanoyl acetaldehyde, allicin, an organic sulfur compound, paprika powder and cyrtomium fortunei to obtain a bacteria-resistant adhesive; S4, pretreating the polypropylene film base layer; S5, compounding every two obtained microporous films on the two sides of one polypropylene film, and obtaining the antibacterial plastic film. Acrylate and mica powder are adhered and fused with pepper powder, cyrtomium fortunei, decanoyl acetaldehyde, allicin and organic sulfur compounds, so the sterilizing and insect-removing effects of the antibacterial agent are improved, the antibacterial agent has the characteristics of moisturizing, locking water, resisting bacteria, killing viruses, removing insect pests and the like, and the raw materials and the production process are simple, safe, environment-friendly, green and pollution-free.

Description

technical field [0001] The invention relates to the technical field of plastic film production, in particular to a method for preparing a bacteria-resistant plastic film. Background technique [0002] The history of the development of the global economy is also the history of human destruction of nature. The Spanish flu in the last century, the Ebola virus, and the bird flu in the United States have brought catastrophic harm to human beings. At the same time, people are forced to study antibacterial and antiviral in various fields. technology. Antibacterial film refers to a film with a certain antibacterial effect. The existing antibacterial film is generally composed of silver ions Ag + Composed of antibacterial layer, PET base layer, silica gel coating, and release film, it fully utilizes the advanced optical film-making technology. It can be applied to mobile phones, and can also be used as a screen protector for common electronic devices such as tablets and laptops to ...
