Problems solved by technology

However, silk wallpapers on the market today are prone to mildew, especially in the Jiangnan area. In addition, there is a certain demand for oil and water resistance in kitchens, restaurants and other places. Obviously, the current wallpaper products cannot meet these needs.
At present, most of the research on improving the antibacterial performance of wallpaper is to add an antibacterial layer on the paper base or other wallpaper substrates by laminating, but this method intelligently guarantees the antibacterial performance of the wallpaper surface, and the antibacterial effect is limited. Once the surface is broken, the antibacterial effect of the wallpaper cannot be guaranteed

Embodiment 1～7

[0027] A kind of wormwood / graphene oxide antibacterial wallpaper is prepared by the following steps:

[0028] S1. The raw material fibers are subjected to beating and screening treatment, and formed into a wet paper web through a forming net, sprayed with graphene oxide / fluorine-containing acrylate modified cellulose after pre-drying, and preparing wallpaper base paper through post-drying and calendering treatment;

[0029] S2. Soak the wallpaper base paper in the above S1 in the mixed extract, immerse for 2-4 hours, and dry to obtain the wormwood / graphene oxide antibacterial wallpaper. The mixed extract is wormwood extract, clove extract and dandelion extract mixture of substances.

[0030] The spraying amount of graphene oxide / fluorine-containing acrylate modified cellulose and the components of the mixed extract are shown in Table 1.

[0031] serial number

Embodiment 8～16

[0033] A kind of wormwood / graphene oxide antibacterial wallpaper, its preparation method is basically the same as embodiment 1, wherein the preparation method of graphene oxide / fluorine-containing acrylate modified cellulose is as follows:

[0034] S11. Preparation of fluorine-containing acrylate modified cellulose: mixing emulsifier, water and hexafluorobutyl methacrylate to pre-emulsify, adding nano-cellulose solution and initiator under inert gas conditions, polymerizing and synthesizing modified cellulose, The polymerization time is 6h, the emulsifier is sodium lauryl sulfate, and the initiator is potassium persulfate;

[0035] S12. Preparation of graphene oxide / fluorine-containing acrylate modified cellulose: prepare a mixed solution of strong alkali, urea and thiourea, cool to -10°C, stir and add the modified cellulose and evenly dispersed graphene oxide in S11 solution, keep the temperature constant, stir and react for 6h, adjust the pH to neutral, and obtain graphene o...

Abstract

The invention discloses a wormwood / graphene oxide anti-microbial wallpaper which is prepared according to the following steps: pulping and screening raw material fibers and adopting a molding net formolding, thereby acquiring a wet paper web; spraying graphene oxide / fluorinated acrylate modified cellulose after pre-drying; preparing a wallpaper body paper through after-drying and calendaring treatment; soaking the wallpaper body paper into a mixed extractive of wormwood extractive, clove extractive and dandelion extractive, and drying, thereby acquiring the wormwood / graphene oxide anti-microbial wallpaper. An anti-microbial graphene oxide / modified cellulose adjuvant is added in a body paper preparation process of the wormwood / graphene oxide anti-microbial wallpaper disclosed by the invention; the waterproof and oil-proof properties of the anti-microbial graphene oxide / modified cellulose adjuvant can further reduce oil and water on the wallpaper so as to avoid bacteria breeding; the combination of various plant anti-microbial extractives in a soaking solution can further promote the anti-microbial effect of a wet tissue and the anti-microbial effect is above 95%; the wormwood / graphene oxide anti-microbial wallpaper has a comprehensive anti-microbial oil-proof effect and can be widely applied to the field of architectural decoration materials.

Description

technical field [0001] The invention belongs to the technical field of building decoration materials, and more specifically relates to a wormwood / graphene oxide antibacterial wallpaper. Background technique [0002] Wallpaper, also known as wallpaper, is a widely used interior decoration material. Because wallpaper has the characteristics of changeable style, various colors, rich patterns, safety and environmental protection, convenient construction, reasonable price, easy to replace and many other interior decoration materials, it is popular in developed countries and regions such as Europe, America, Southeast Asia, Japan and South Korea. gained considerable popularity. With the improvement of people's living standards in our country, wallpaper is widely favored by consumers because of its variety of colors and styles. However, the silk wallpapers on the market today are prone to mildew, especially in the Jiangnan area. In addition, there is a certain demand for oil and w...
