Abstract

The invention belongs to the technical field of air purification, and particularly relates to a nano titanium alginate air purifying material and a preparation method thereof. The method uses a microporous medium matrix, an oxidizer, a catalyst and a pH developer as raw materials and comprises the following steps: S1. centrifugal impregnation loading; S2. autoclave loading; S3. drying; and S4. carrying out surface development treatment and the like to obtain the air purifying material. According to the preparation method, the centrifugal impregnation mode is utilized to load a catalytic oxidizer on the microporous medium wall surfaces and microporous channels, and has the advantages of high loading speed and high loading degree; the autoclave loading can enhance the loading degree under the actions of saturated vapor pressure and internal energy, and can optimize the microporous medium structure and enhance the perforated holes, thereby being beneficial to the enhancement of the purification property; and after the surface development treatment, the acidic substances generated during purification can discolor the purifying material surface, thereby obtaining the experiences of purifying capacity and effects. The air purifying material provided by the invention has the advantages of thorough purification, high speed, high durability and the like.

Description

technical field [0001] The invention belongs to the technical field of air purification, and in particular relates to a nano-titanium alginate air purification material and a preparation method thereof. Background technique [0002] Air purification materials absorb and decompose harmful substances in the air through physical and chemical methods. The application of air purification materials is an effective way to control air pollution sources. The well-known patent "Composite Air Cleaner Containing Nano Minerals and Its Preparation Method" (CN201010112863.X) is composed of natural minerals, molecular sieves, photocatalysts, modifiers, foaming agents, and surfactants, and is effective against organic pollutants in the air. The pollutant decomposition efficiency is high, but the disadvantage is that the purification material is a selective adsorption material, and the purification type is not wide; the patent "a photocatalyst multifunctional diatom purification particle and ...
