Abstract

The invention discloses a compound photocatalysis antimicrobial coating air filter material and a preparation method thereof. The method is as follows: respectively preparing nano titanium oxide collosol, nano zinc oxide collosol and nano copper-nickel compound metallic collosol; preparing compound photocatalysis antimicrobial finishing agent; in cationic waterborne polyurethane adhesive emulsion, firstly, adding nano copper-nickel compound metallic collosol, nano titanium oxide collosol and nano zinc oxide collosol, stirring, and then adding deionized water; at room temperature, stirring and dispersing to form stable emulsion compound photocatalysis antimicrobial finishing agent; preparing finishing agent accounting for 5-15 wt% of air filter material to be treated; adding deionized water until reaching 100%; adopting a continuous padding technology to perform dip coating classification to the filter material to be treated; and drying and backing. The invention solves the problems of unfavorable nano photocatalysis antimicrobial effect, single effect and poor laundering durability, and improves the laundering durability of compound coating.

Description

technical field [0001] The invention relates to a composite photocatalytic antimicrobial air filter material and a preparation method thereof, in particular to an air filter material impregnated with a composite photocatalytic and antimicrobial finishing agent and a preparation method thereof. Background technique [0002] Composite photocatalytic and anti-microbial functional air filter products have anti-killing, inactivation and decomposition effects on bacteria, viruses and other microorganisms contained in the air during the air filtration process. Decompose organic matter such as formaldehyde and other harmful gases in the air, so that a large number of harmful microorganisms and harmful gases in the air can be removed, effectively preventing the air conditioning system from posing a pathogenic threat to the human body due to the repeated use of air, protecting people's health and reducing diseases Communication has important practical significance. At present, most o...
