Problems solved by technology

[0004] The technical problem to be solved by the present invention: Aiming at the defect that conventional wallpaper contains formaldehyde and other harmful substances, and formaldehyde cannot be eliminated, the present invention improves a preparation method of wallpaper with air purification function. The present invention uses tetrabutyl titanate as Prepare nano-titanium dioxide from titanium source, and then use tetraethyl orthosilicate as silicon source to form a nano-silicon dioxide film to coat the surface of nano-titanium dioxide, and then grind it with diatomaceous earth, tourmaline, polyvinyl alcohol, etc. to form a coating film Slurry, and finally coating the coating slurry on the surface of non-woven paper, and then after embossing and drying, the wallpaper with air purification function can be obtained

Abstract

The invention discloses a preparation method of wallpaper with air purification function, belonging to the technical field of wallpaper. In the present invention, tetrabutyl titanate is used as titanium source to prepare nano-titanium dioxide, and then ethyl orthosilicate is used as silicon source to form nano-silicon dioxide film coated on the surface of nano-titanium dioxide, and then it is mixed with diatomaceous earth, tourmaline, Polyvinyl alcohol, etc. are ground and prepared into a coating solution, and finally the coating solution is coated on the surface of non-woven paper, and then embossed and dried to obtain a wallpaper with air purification function. The present invention uses diatomite, cellulose ether, and wood fiber as the matrix of the coating liquid, which can efficiently absorb free formaldehyde in the air, and then catalyzes and decomposes the negative ions generated by modified nano-titanium dioxide and tourmaline to achieve formaldehyde removal. and purify indoor air.

Description

technical field [0001] The invention discloses a preparation method of wallpaper with air purification function, belonging to the technical field of wallpaper. Background technique [0002] Wallpaper is a widely used interior decoration material. Because of its various colors, rich patterns, luxurious style, safety and environmental protection, convenient construction, and reasonable price, it has been widely popularized in developed countries and regions such as Europe, America, Southeast Asia, and Japan. .
