Description

A functional wallpaper material that purifies the air

technical field

The invention relates to a wallpaper material in the technical field of interior decoration materials, in particular to a functional wallpaper material capable of purifying air.

Background technique

Indoor decoration materials and furniture pollution are the main aspects of indoor air pollution. Materials such as paint, wallpaper, plywood, particle filler, and interior wall paint all contain harmful substances such as formaldehyde, benzene, ethanol, and chloroform. The above substances are quite carcinogenic, and the environmental pollution caused by interior decoration is becoming more and more serious. The United States, A survey by Japan's specialized agencies found that the indoor air pollution of many civil and commercial buildings is 2-5 times that of outdoor air pollution, and about 30% of residents have "new house syndrome" caused by the use of harmful chemicals. In addition, office automation Electromagnetic waves of different wavelengths and frequencies are generated by equipment and household appliances such as microwave ovens, radios, televisions, computers, and mobile phones. These electromagnetic waves fill the space, can penetrate many substances including the human body, and receive excessive radiation doses.

Through literature search of the prior art, it is found that the Chinese Patent Publication No. CN1752342A, the publication date is March 29, 2006. The name of the invention is: wallpaper for reducing new home syndrome, the patent reads as: providing a wallpaper for reducing new home syndrome, because it is manufactured from a very small amount of harmful volatile organic compounds, the result is no Emissions of volatile organic compounds, or very little if any, have the effect of reducing new home syndrome. Its shortcoming: only in the manufacture of wallpaper, a very small amount of organic compounds is added to reduce the release of organic compounds, but it cannot effectively remove formaldehyde and electromagnetic radiation, and it cannot remove indoor air pollution, nor can it play an antibacterial and anti-bacterial role. Mildew, the release of negative ions and the role of anti-electromagnetic radiation. And these air pollutions are very harmful to human beings.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies and defects in the prior art, and provide a functional wallpaper material that can purify the air. The wallpaper prepared by this material can remove formaldehyde, remove peculiar smell, antibacterial, anti-mildew, release negative ions, and resist electromagnetic waves. Radiation will greatly improve people's indoor air quality and solve indoor air pollution.

The present invention is achieved through the following technical solutions. The functional wallpaper material of the present invention contains the following components and weight percentages:

Titanium dioxide nano-powder 1.5%-2.5%

Silica nano-sized powder 1%-2.5%

Zinc oxide powder 0.5%-1.5%

Negative ion powder 2%-3.5%

Inorganic antibacterial powder 0.5%-1.5%

Auxiliary 3%-30%

The conductive powder is obtained on the basis of nanomaterials through active treatment and doping treatment of conductive factors to form a firm conductive layer on the surface of the base, so that the material has lasting conductivity, and is directly purchased from the market.

The particle diameters of the titanium dioxide nanometer powder, silicon dioxide nanometer powder, zinc oxide powder and negative ion powder are 50-500 nanometers. The titanium dioxide nanometer powder is a kind of photocatalytic material.

The negative ion micropowder is boron-containing silicate tourmaline, and its composition contains boron, aluminum, silicon, manganese, magnesium, calcium, iron and the like.

The inorganic antibacterial powder contains CuO, SnO, ZnO and silver-containing, nitrogen-containing inorganic and high molecular compound composite antibacterial and mildew-proof materials.

The auxiliary agent is a mixture of whitening agent, viscosity reducer, stabilizer and foaming agent. The weight content of the preferred components is: 25% whitening agent, 12% viscosity reducer, 12% stabilizer, 50% foaming agent and 1% stabilizer.

Weigh the above-mentioned materials according to the proportion, then mix them in the container, and stir them evenly to form a paste, so as to obtain a PVC functional wallpaper material (this material is a paste), which is coated and bonded to the wallpaper by hot-melt method. On the base paper, after heat embossing (foaming can also be performed after heat embossing), the pattern is printed to form a functional, concave-convex pattern wallpaper.

The base paper may also be at least one selected from base paper for base paper substrate, base paper for wallpaper, non-woven fabric, base cloth, and composite paper of non-woven fabric and base paper.

The nonwoven fabric is preferably a synthetic fiber nonwoven fabric based on rayon, polyester, polypropylene, polyvinyl chloride and polyethylene terephthalate.

The base cloth refers to cotton fabric.

The invention is used for wallpaper, and the wallpaper prepared by using the material of the invention has various performance indicators of the wallpaper itself, and at the same time has the functions of eliminating formaldehyde, eliminating peculiar smell, antibacterial, anti-mildew, anti-electromagnetic radiation, releasing negative ions, and purifying air. The antibacterial material (inorganic antibacterial powder) in the wallpaper can combine with the bacterial cell membrane to achieve the purpose of sterilization when in contact with bacteria. When the photocatalytic material (titanium dioxide nano-scale powder) in the wallpaper is under light conditions, it can produce electronic transitions, produce strong oxidants and strong reducing agents, so that the wallpaper can degrade organic pollutants and antibacterial effects, and completely degrade organic pollutants into water. And inorganic ions, remove formaldehyde, remove odor. The well-dispersed conductive powder makes it form a firm conductive layer on the surface of the substrate, making the wallpaper have lasting conductivity and effectively eliminating electromagnetic radiation. Negative ion powder can passively release vitamins in the air - natural negative ions.

After testing: the formaldehyde removal rate reaches 80-92%, the odor removal rate reaches 70-85%, the negative ion release rate reaches 1200-2000/cubic centimeter, the anti-electromagnetic radiation performance (dB) is 3-15, and the antibacterial rate is greater than 90% (for Tested strains: Escherichia coli, Staphylococcus aureus, Bacillus megaterium, Bacillus subtilis, Pseudomonas fluorescens), anti-fungal grade 0--1, far-infrared emission rate (4-14μm) 75-82%

Compared with the background technology, the detection results can not only remove formaldehyde and odor in the air, but also have the functions of antibacterial, anti-mildew, release of negative ions, anti-electromagnetic radiation, and far-infrared emissivity.
