Conditioning deodorization antibiotic mildew-proof wallpaper

Abstract

The present invention relates to a humidity-regulating, odor-removing, antibacterial and mould-proof wallpaper, which can effectively regulate the air humidity, absorb the polluting gases in the air and inhibit the reproduction of bacteria and mould. The wallpaper is produced by the drying, cooling and embossing of a basal paper and pasty material coated on the basal paper. According to weight percentages, the pasty material is made from 20 percent to 60 percent of PVC, 25 percent to 50 percent of filling, 5 percent to 15 percent of titanium pigment, 3 percent to 5 percent of the mixture of nano-ZnO and nano-TiO2, 1.5 percent to 3.5 percent of mould inhibitor, 1.5 percent to 3.5 percent of plasticiser, 0.5 percent to 2.5 percent of viscosity depressant, 1.5 percent to 2.5 percent of stabilizer and 0.5 percent to 1.0 percent of bisphenol A. Firstly, the PVC is made into paste and then uniformly mixed with the bisphenol A and the plasticiser; secondly, after being uniformly mixed with the filling, the paste is uniformly mixed with the titanium pigment, the nano-ZnO, the nano-TiO2 and the mould inhibitor and then the stabilizer; and finally, the viscosity depressant is added to regulate the viscosity of the paste in order to obtain the pasty material, which is then coated on the basal paper. The wallpaper has the advantages of no toxicity, no offensive odor, environment-friendliness, long service life, waterproofness and no deformation.

Description

1. Technical Field [0001] The invention relates to a building decoration material, in particular to a moisture-regulating and deodorizing anti-bacterial and anti-mildew wallpaper. 2. Background technology [0002] There are many types of wallpaper, including: paper-based wallpaper, textile wallpaper, natural material wallpaper, plastic wallpaper, glass fiber wallpaper (also called glass fiber) and so on. [0003] Paper-based wallpaper This is the earliest wallpaper, and the surface can be printed with patterns or embossing. The base has good air permeability, which can make the moisture in the base layer of the wall radiate outwards without causing discoloration, bubbling and other phenomena. This kind of wallpaper is cheap, but the disadvantages are poor performance, water resistance, inconvenient cleaning, and inconvenient construction. Currently, it is less produced; [0004] Textile wallpaper This is a higher-level variety of wallpaper. Mainly woven with silk, wool, cotton, h...

Problems solved by technology

[0009] In view of the above situation, in order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a humidity-adjusting, deodorizing, antibacterial and mildew-proof wallpaper, which can effectively solve the problem of adjusting air humidity, absorbing polluted gases in the air, and inhibiting the reproduction of bacteria and mold on the wallpaper. It is beneficial to environmental protection and people's health. The technical solution is to use base paper as base paper, polyvinyl chloride (pvc) as film-forming material, fibrous sepiolite or attapulgite and zeolite as filler, titanium White powder as pigment, and nanometer ZnO, TiO 2 and antifungal agent and other auxiliary components, through compounding, embossing and other processes to make, therefore, the present invention is: recoating (coating) slurry paste on base paper and base paper through drying, cooling, pressing The said slurry paste is calculated by weight percentage: PVC 20-60%, filler 25-50%, titanium dioxide 5-15%, nano-ZnO and nano-TiO 2 Mixture 3-5%, anti-mold agent 1.5-3.5%, plasticizer 1.5-3.5%, viscosity reducer 0.5-2.5%, stabilizer 1.5-2.5% and bisphenol A 0.5-1.0%, the total sum is 100 %, wherein, PVC is first made into a paste (also known as paste resin, PVC can be heated and melted into a slurry paste) mixed with bisphenol A and plasticizer and stirred evenly, then after adding fillers and mixed well, Add titanium dioxide (titanium oxide) and nano-ZnO, nano-TiO 2 After mixing with antifungal agent, dispersing and stirring evenly, add stabilizer, mix and stir evenly, and finally add viscosity reducer to adjust viscosity to make recoating slurry paste, every 80~100g / m 2 Recoat 100g to 300g of slurry paste on the base paper (that is, apply 100g to 300g of slurry paste on each square meter of base paper), dry, gel, and cool, and then print the wallpaper of the present invention.
