Problems solved by technology

[0003] At present, commercially available air purifiers mainly use filters, activated carbon and other materials to purify the air. Although they have a certain filtering function, the purification effect is limited.
However, if the purification effect is good, the structure of the filter element is complex and the cost is high.

Abstract

The invention relates to the technical field of air filtration, in particular to a chemical filter and a preparation method of a chemical filter material of the chemical filter, and the chemical filter material is prepared from the following raw materials in parts by weight: 20-30 parts of manganese dioxide modified activated carbon, 10-15 parts of fine silicon dioxide aerogel, 5-10 parts of carbon fiber and 5-10 parts of modified chitosan cellosilk. The preparation method comprises the following steps: S1, weaving the carbon fibers and the modified chitosan fibers into a net in a staggered manner to obtain the filter screen; s2, ultrasonically dispersing the manganese dioxide modified activated carbon into 6 times of deionized water, adding the fine silicon dioxide aerogel, and obtaining a mixed adsorption material for later use after the silicon dioxide aerogel is completely adsorbed; and S3, uniformly spraying a layer of mixed adsorption material on each of the front and back surfaces of the filter screen, and drying to obtain the filter screen. The obtained filter material has very strong adsorption and degradation capabilities and is low in cost.

Description

technical field [0001] The invention relates to the technical field of air filtration, in particular to a chemical filter and a preparation method of the chemical filter material. Background technique [0002] With the development of society, the public's requirements for environmental protection and health are also increasing. Air pollution in closed and semi-closed spaces (including indoor space, underground space, and air pollution in cars) is an invisible air pollution that has been more and more attention. In order to purify the indoor air and effectively improve the cleanliness of the indoor air, an air purifier with the function of purifying the air has emerged as the times require. [0003] At present, commercially available air purifiers mainly use materials such as filter screens and activated carbon to purify the air. Although they have a certain filtering function, the purification effect is limited. However, if the purification effect is good, the structure of...
