Problems solved by technology

However, glue is also used in the construction of wall coverings, which are prone to mildew due to moisture. In addition, the rapid development of the market has also led to uneven quality of some home decoration materials. A large number of inferior materials will continuously release toxic substances, such as formaldehyde, TVOC, Benzene series, ammonia, radon, etc., most substances have been confirmed as carcinogens and mutagens, which are more harmful to the human body

Abstract

The invention discloses wall cloth with formaldehyde removal, peculiar smell removal and bacteriostasis functions and a preparation method thereof. The wall cloth comprises a surface layer, a composite fiber adsorption layer, a nanoparticle catalytic decomposition layer, a bacteriostasis fiber layer and a point distribution glue layer. A negative ion smell removal layer formed on the surface of the wall cloth generates negative ions, so that the health care effect of the wall cloth is improved, and the indoor peculiar smell is removed; through the arrangement of the composite fiber adsorptionlayer and the nanoparticle catalytic decomposition layer, the generation of self harmful gas and peculiar smell of the wall cloth can be reduced, and external harmful gas and peculiar smell can also be adsorbed and decomposed; and through the arrangement of the bacteriostasis fiber layer, the breeding of bacteria can be effectively reduced, and the living safety is improved. The preparation process is regulated on the basis of the existing melt blowing, coating scraping and spray coating processes; the manufacturing process is advanced; the implementation is easy; and the industrial duplication capability is high.

Description

technical field [0001] The invention belongs to the technical field of decorative materials, and in particular relates to a wall cloth with the functions of removing aldehydes, removing peculiar smells and inhibiting bacteria and a preparation method thereof. Background technique [0002] With the continuous improvement of people's quality of life, the problem of indoor air quality has gradually become the focus of people's attention. In people's daily life, an average of 12m is inhaled every day 3 However, people spend more than 80% of their time indoors every day. However, there are often many toxic and harmful gases in the house after decoration, mainly including five major items: benzene, toluene, xylene, formaldehyde, TVOC (total volatile Sexual organic substances), these five toxic and carcinogenic substances are widely present in commonly used home decoration materials or finished home decoration products, such as adhesive components in wallpaper, wall coverings, fur...
