Abstract

The invention belongs to the technical field of decorative wallpaper, and specifically relates to a preparation method of a composite wallpaper for purifying indoor air. The preparation method comprises following steps: (1) preparing a purifying agent; (2) adding a surfactant into the purifying agent obtained in the step (1), adding paper pulp, mixing, and stirring to obtain composite slurry, wherein the mass ratio of the purifying agent to the surfactant is 1:2-5, and the mass ratio of the purifying agent to the paper pulp is (0.2-0.5):1; and (3) spraying the composite slurry onto one side ofSMS nonwoven cloth, then covering a layer of SMS nonwoven cloth onto the composite slurry coated side, and carrying out hot pressing and laminating in a roller press to obtain the composite wallpaper. IRMOFs, tetra-isopropyl titanate, and tin tetrachloride are mixed to prepare the purifying agent applied to the wallpaper, the obtained wallpaper can efficiently adsorb pollutants in the indoor air,furthermore, the many active reaction sites of the purifying agent are utilized to catalytically degrade the pollutants, and the indoor air is purified.

Description

technical field [0001] The invention belongs to the technical field of decorative wallpaper, and in particular relates to a preparation method of composite wallpaper for purifying indoor air. Background technique [0002] With the continuous improvement of living standards, people have higher and higher requirements for improving the living environment and improving air quality. People need a fresh, clean and hygienic living environment. Indoor air pollution is increasingly becoming a concern of people. The pollutants in indoor air mainly include: formaldehyde, benzene, ammonia, radon, aromatic hydrocarbons, tetrachlorethylene, etc. Most of these pollutants mainly from decoration materials are irritating. The peculiar smell in the room not only affects people's mood, but also threatens people's health. [0003] At present, the methods for indoor air pollution control mainly include filtration method, ozone purification method, low-temperature plasma purification method and...
