Sticker with anti-fouling and antibacterial properties and preparation method thereof

Abstract

The invention provides a sticker with anti-fouling and antibacterial properties, the sticker is composed of three layers, including a waterproof, oil-proof and anti-fouling layer, a functional composite fiber non-woven fabric layer and a release layer, and the functional composite fiber non-woven fabric layer is prepared by grafting esterified plant fibers and modified chemical fibers and adsorbing nano-silver ions. The invention further provides a preparation method of the anti-fouling and antibacterial sticker. The preparation method comprises the steps of esterification of the plant fibers,modification of the chemical fibers, preparation of the composite modified fibers, preparation of the composite fiber non-woven fabric, adsorption of the nano-silver particles and preparation of thesticker. The sticker with the anti-fouling and antibacterial properties is better in waterproof and anti-fouling properties, free of warping, not prone to crack, good in antibacterial property and antistatic property, excellent in high-temperature resistance and weather resistance and capable of keeping the natural hand feeling and appearance of the non-woven fabric sticker.

[0003] Non-woven substrate stickers are made of natural plant fibers or synthetic fibers, which are more environmentally friendly, but they are prone to mold and contamination during use, which affects the service life

Moreover, in daily life, the stickers in the room will inevitably be stained, which not only affects the appearance but also breeds bacteria, especially in families with children, who like to scribble on the stickers if they are not careful, which is difficult to deal with. , Those invisible bacteria that breed are even more worrying for parents. At the same time, in places such as hospitals and schools where there is a high flow of people and where bacteria are easy to spread, the stickers used should be more anti-fouling and anti-bacterial. Some existing anti-bacterial stickers The use of high toxicity or weak antibacterial effect is prepared from antibacterial agents with pungent odors, which affects the safety of people's use
