Problems solved by technology

[0006] In the prior art, some nano-functional materials are used, such as nano-titanium dioxide and nano-silver, but these nanoparticles are very prone to agglomeration due to their large specific surface area and large specific surface energy in practical applications, thus affecting their actual nano-antibacterial properties. or aldehyde removal effect
On the other hand, nanoparticles are easily embedded in the surrounding medium in the application system and cannot be exposed on the surface of the wallpaper, which affects their contact with bacteria, viruses, molds and other substances, resulting in the application of these nanoparticles in wallpaper. Or the effect of removing aldehyde is not ideal

Abstract

The invention discloses multifunctional wallpaper which comprises a base layer and a functional layer. The functional layer comprises a first micro-nano composite material and a second micro-nano composite material. The first micro-nano composite material is one or two selected from nano-titanium dioxide and nano-zinc oxide and one or the combination of more selected from nano-agcl, nano-silver oxide and nano-silver and is carried on an inorganic nonmetal micron carrier; and the second micro-nano composite material is one or two selected from nano-titanium dioxide and nano silicon dioxide hydrate and is carried on an inorganic nonmetal micron carrier. The functional layer can preferably comprise a third micro-nano composite material, and the third micro-nano composite material is nano zinc oxide and one or the combination of more selected from nano-copper oxide, nano-copper hydroxide and nano-cuprous oxide. The multifunctional wallpaper has excellent functions of antibiosis, anti-virus, formaldehyde removal, mold resistance, corrosion resistance, pollution prevention and water repellency. A coating composition for the multifunctional wallpaper is further disclosed.

Description

technical field [0001] The invention relates to a multifunctional wallpaper and a coating composition for the multifunctional wallpaper. Background technique [0002] With the improvement of living standards, people pay more attention to the health and environmental protection of decorative materials while pursuing the diversification and individualization of decorative materials. [0003] Wallpaper, also known as wallpaper, is a kind of interior decoration material with strong artistic expression. It is loved by more and more people because of its changeable colors, beautiful patterns and strong three-dimensional layering. [0004] In recent years, as consumers pay more attention to environmental health and safety, the demand for wallpaper has extended from the simple and beautiful decoration to antibacterial, mildew-proof, and environmental air purification. On the one hand, the traditional wallpaper itself is easy to absorb moisture and mildew, and it is easy to breed ba...
