Embodiment 1

[0034] (1) Preparation of N-aryl-2-(benzisothiazolin-3-one-2-yl)formamide organic antibacterial agent. Weigh 20mmol of bistrichloromethyl carbonate and 10mL of toluene, add to a three-necked flask with a volume of 100mL equipped with stirring, reflux condenser and constant pressure funnel and stir, add 30mmol of o-methyl to the constant pressure funnel The mixed solution of aniline and 10mL of toluene was slowly added dropwise to the flask. When the dropwise addition was completed, the reaction was heated under reflux for 5h. When the reaction was completed, 30mmol of benzisothiazolin-3-one was directly added to the flask, and Add 20mL of toluene to carry out reflux reaction. After the reaction is completed, naturally cool to room temperature, filter under reduced pressure, wash with acetone to remove unreacted substances, and place in a vacuum drying oven to dry at 50°C for 24h. The white needle-like crystals obtained were N-aryl-2-(benzisothiazolin-3-one-2-yl)formamide;

Abstract

The invention discloses a multifunctional composite filter screen material for an air purifier and a preparation method thereof. The multifunctional composite filter screen material is prepared from the following ingredients in percentage by weight: 5 to 10 mass percent of N-aryl-2-(benzisothiazolin-3-ketone-2-yl)methanamide organic antibacterial agents, 10 to 15 mass percent of Ag-MOFs compositematerials, 25 to 30 mass percent of terbium-doping mesoporous TiO2 nanometer photocatalysts and 50 mass percent of active carbon fiber. The bacteriostasis rate of the composite filter screen materialon escherichia coli can reach 98 percent; the removal rate on formaldehyde reaches up to 99 percent.

Description

[0001] This application is a divisional application, the original patent number is: 201710513744.7, the application date is June 23, 2017, and the title of the invention is: a multifunctional composite filter material for an air purifier and its preparation method. technical field [0002] The invention relates to a multifunctional composite filter material for an air purifier and a preparation method thereof, which belongs to the technical field of composite functional materials and is suitable for the filter material of an air purifier. Background technique [0003] Air purifiers are small household appliances used to purify indoor air, mainly to solve the problem of indoor air pollution caused by decoration or other reasons. Since the release of pollutants in indoor air is characterized by persistence and uncertainty, the use of air purifiers to purify indoor air is an internationally recognized method to improve indoor air quality. [0004] The filter screen is the core ...
