Embodiment 1

[0029] A kind of air purification material, it is prepared by following method:

[0030] 30 kilograms of activated carbon and 100 kilograms of calcium peroxide solution with a concentration of 1.8wt% were put into a centrifuge, impregnated with a centrifugal speed of 50 r / min for 8 hours, and then autoclaved in an autoclave with a saturated vapor pressure of 0.6 MPa , autoclave for 12 hours, after natural drying, put the activated carbon dry particles loaded with oxidant in a rolling polisher for polishing, and use a spray gun to compound 1 kg of methyl orange, 2 kg of water and 0.5 kg of titanium dioxide photocatalyst to obtain The spraying liquid is evenly sprayed on the surface of the dry particles, and the air purification material is obtained after spraying.

Embodiment 2

[0032] A kind of air purification material, it is prepared by following method:

[0033] 30 kilograms of pure diatoms and 100 kilograms of sodium percarbonate solution with a concentration of 1.8wt% were put into a centrifuge, immersed for 8 hours at a centrifugal speed of 50 r / min, and then autoclaved in an autoclave with a saturated vapor pressure of 0.6 MPa, autoclaved for 12 hours, after natural drying, the pure dry diatom particles loaded with oxidants are placed in a rolling polisher for polishing. While polishing, 1 kg of methylene blue, 2 kg of water and 0.5 kg of titanium dioxide are mixed with a spray gun. The spray liquid obtained by compounding the photocatalyst is uniformly sprayed on the surface of the dry particles, and the air purification material is obtained after spraying.

Abstract

The invention belongs to the technical field of air purification, and particularly relates to a method for preparing an air purification material from a microporous medium through catalytic oxidation and the air purification material. According to the method, the air purification material is prepared by taking a microporous medium substrate, an oxidizing agent, a catalyst and a pH color developing agent as raw materials through the steps of 1 centrifugal impregnation loading, 2 steaming and pressing loading, 3 drying, 4 surface color developing treatment and the like; the catalytic oxidizing agent is loaded on the wall face of the microporous medium and microporous channels through a centrifugal impregnation mode, and therefore the loading speed and the loading degree are high; by means of steaming and pressing loading, the loading degree can be intensified under the saturated vapor pressure and internal energy, the structure of the microporous medium can be optimized, hole penetrating is improved, and improvement of the purification property is promoted; after surface color developing treatment, and the color of the surface of the purification material can be changed by acidic materials generated in purification, so that the experience feeling of the purification capacity and effect is obtained. The air purification material has the advantage of achieving thorough, rapid and lasting purification.
