Abstract

The invention belongs to the technical field of decorative wallpaper, in particular to a method for preparing a composite wallpaper for purifying indoor air, comprising: (1) preparation of a purifying agent; (2) adding 2 to 5 times the amount of surfactant, then add the pulp and mix and stir to obtain the composite slurry; wherein, the mass ratio of the purifying agent to the pulp is (0.2-0.5): 1; (3) spray the composite slurry on the SMS non-woven One side of the cloth is then covered with a layer of SMS non-woven fabric and then entered into a roller press for hot pressing and bonding to obtain the composite wallpaper; the present invention utilizes IRMOFs materials and tetraisopropyl titanate and tetrachloride Tin is mixed to prepare purification materials and used in composite wallpapers. The obtained composite wallpapers can efficiently adsorb pollutants in indoor air, and further catalyze the degradation of pollutants through many active reaction sites in the purifier, thereby To achieve the purpose of purifying indoor air.

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...
