Embodiment 1

[0025] Mix butyl titanate and absolute ethanol uniformly at a volume ratio of 1:4.4 to make liquid A, and then uniformly mix deionized water, absolute ethanol and glacial acetic acid at a volume ratio of 1:1.3:0.24 to form a mixed liquid B , Add solution A dropwise (at a rate of 3 mL / min) to the prepared solution B in a water bath at 40°C, and the volume ratio of solution A to solution B in the mixed solution is 2.4:1. At the same time, a constant temperature magnetic stirrer was used for rapid stirring to hydrolyze the butyl titanate. After continuous stirring for about 3 hours, a white transparent TiO2 gel was formed after filtration.

[0026] Mix and stir potassium permanganate, manganese acetate and water evenly according to the mass ratio of 1:1.4:6.5, transfer the mixed solution into a reaction kettle with a polytetrafluoroethylene lining, and then add distilled water to adjust to the inner lining of the reaction kettle. 65% of the volume, sealed, and placed in a vacuum...

Abstract

The invention discloses an air purifying material with a high catalytic oxidation activity. A preparation method of the air purifying material comprises the following steps: 1, adding TiO2 gel prepared through a sol-gel process into a hydrothermal synthesized alpha-MnO2 nanorod solution according to a mass ratio of 1:(1.0-1.4), and filtering the above obtained mixed solution to obtain a filter cake A; 2, dissolving KIO3 in 100DEG C water to prepare a potassium iodate solution with the mass fraction of 15-23%, and mixing with a titanate coupling agent or silicate ester coupling agent modified nano-ZnO2 according to a mass ratio of 1:(15-25) in order to prepare a photocatalyst activator B; and 3, mixing the filter cake A prepared in step 1 with the photocatalyst activator B, tourmalinite powder and a binder according to a mass ratio of 1:(0.15-0.30):(0.20-0.25):(0.25-0.30), uniformly stirring, granulating to form balls or extruding to form strips, and drying to prepare the air purifying material. The material has a strong air purifying capability and can be conveniently applied.

Description

technical field [0001] The invention relates to a filter material, in particular to an air filter material. Background technique [0002] In recent years, the problem of air pollution has been an urgent problem to be solved by the governments of various countries. Excessive sulfides, carbon monoxide (CO) and nitrogen oxides in the air are harmful gases that affect human health; industries such as energy, chemical industry, metallurgy, and transportation use fuel The flue gas released by fossil fuels (coal, oil, natural gas, etc.) contains a large amount of SO2 and NOx, causing serious pollution to the atmosphere. In addition, all kinds of dust produced by human activities, as well as the pollution of solid suspended particles such as sand and dust caused by climate deterioration, and the volatile organic pollutants from various decorative materials and oral chemicals are increasing. land into residential and public buildings, leading to a sharp increase in the pollution of ...
