Problems solved by technology

This kind of wallpaper does play a certain decorative role in beautifying the interior walls, but because the PVC paste uses a large number of PVC, DOP and other chemical products, not only the air permeability is extremely poor, the wall moisture cannot be evaporated normally, and bacteria will multiply for a long time. The PVC plastic coating itself is also volatilizing chemical gases, which is very unfavorable to indoor air environmental protection
[0004] At present, the main production method of functional wallpaper is to compound functional materials on the surface of the wallpaper, such as coating the surface with an antibacterial layer to endow the wallpaper with antibacterial and deodorizing properties, but the antibacterial effect will wear and fall off with the coating weakened, less durable
CN102268835A adds functional powder directly to wallpaper base paper slurry to endow wallpaper with antibacterial, air-purifying and other functions, but in the process of processing, due to the poor combination of functional powder and pulp fiber, it is easy to cause the loss of raw materials, resulting in waste

Embodiment 1

[0090] Embodiment 1: A kind of antibacterial and antifungal agent and antibacterial and antifungal wallpaper based on it:

[0091] The present embodiment firstly provides a kind of antibacterial antifungal agent, comprises by weight percentage content:

[0092] - 4.4 wt% mulberry cellulose nanofibrils / graphene / polymethyl methacrylate composite,

[0093] - 0.9 wt% curcumin monophosphate monopotassium salt,

[0094] - 0.1wt% burdock seed extract compound,

[0095] - 15.0 wt% polyvinylpyrrolidone PVP,

[0096] - 10.0 wt% polyethylene glycol PEG,

[0097] - the remaining amount of deionized water;

[0098] Wherein the structural formula of the arctium extract compound is shown in formula (1);

[0099] And the dry matter weight ratio of the mulberry cellulose nanofibril / graphene / polymethyl methacrylate compound to the alkali metal salt of curcumin monophosphate and the burdock seed extract compound is 44:9:1.

[0100] The aforementioned antibacterial and antifungal agents a...

Embodiment 2～9

[0129] Examples 2-9: Other antibacterial and mildew-proof wallpapers:

[0130] Embodiments 2 to 9 respectively provide an antibacterial and antifungal wallpaper, an antibacterial and antifungal agent and a wallpaper based on it, and the formula and preparation method of the antibacterial and antifungal agent and the wallpaper based on it are basically the same as those in Example 1 , the difference is only the mulberry cellulose nanofibril / graphene / polymethyl methacrylate composite (hereinafter referred to as the composite) of the antibacterial and antifungal agent of embodiments 2~9, curcumin monophosphate monopotassium salt (hereinafter referred to as curcumin salt) and the content of burdock fruit extract compound (hereinafter referred to as compound) are slightly different from Example 1, the detailed difference is as shown in Table 1, and according to the same method as Example 1 to prepare antibacterial and anti-mildew agents and wallpapers based on them.

[0131] The f...

Embodiment 10

[0133] Example 10: Another antibacterial and mildew-proof wallpaper:

[0134] This embodiment provides another antibacterial and antifungal agent and the wallpaper based on it, and the formula and preparation method of the antibacterial and antifungal agent and the wallpaper based on it are basically the same as in Example 1, the difference is only in this embodiment In the antibacterial and antifungal agent, sisal fiber was used instead of mulberry fiber to prepare cellulose nanofibrils and finally the antibacterial and antifungal agent was prepared, and the antibacterial and antifungal agent and the wallpaper based on it were prepared according to the same method as in Example 1.

Abstract

The invention relates to wallpaper, and concretely relates to antibacterial and mildew-proof wallpaper and a preparation method thereof. The wallpaper comprises: a wallpaper base layer containing alginate fibers and all-wood pulp fibers; an antibacterial and mildew-proof agent sprayed on the surface of the wallpaper base layer; and a PVC paste applied to the surface of the wallpaper base layer ina coating manner. The alginate fibers and all-wood pulp are subjected to selection, mixing, pulping, papermaking and drying to obtain the wallpaper base layer; the antibacterial and mildew-proof agentis uniformly sprayed on the surface of the wallpaper base layer; the surface of the wallpaper base layer is coated with the PVC paste to obtain wallpaper base paper; and a pattern is printed on the wallpaper base paper in an extruded mode to obtain corresponding lines, and the wallpaper is obtained by cutting the wallpaper base paper into required specifications after drying and shaping. The antibacterial and mildew-proof wallpaper has excellent antibacterial and mildew-proof performance, has an antibacterial rate on common harmful germs of 99.5% or above, is harmless to human bodies and canadsorb indoor formaldehyde gas and purify room air, damage of ionizing radiation to the human bodies can be reduced due to the excellent electromagnetic shielding effect, and the use experience is good.
