Abstract

The invention relates to an environmental filter element material for an air purifier. Modified active carbon, mesoporous nanoscale titanium dioxide and coconut shell activated carbon are added. The modified active carbon has strong adsorption capacity; mesoporous nanoscale titanium dioxide greatly enhances UV response capability of the filter element material and improves photo-catalytic reaction activity of the filter element material and formaldehyde degradation adsorption removal efficiency; with addition of rare earth oxide, catalytic activity can be enhanced, and formaldehyde removal efficiency is further improved; as modified attapulgite, bentonite, diatomite and natural Chinese medical stone have micropore structures as carriers, catalytic activity, adsorption capacity and microbicidal efficacy are greatly raised; with addition of negative ion powder, negative ions which are beneficial to human health also can be released; and a Chinese herbal extracting solution and fig peel hydrolysate are both plant extracts, the filter element material is safe and environmentally friendly, contains no toxic chemical substances and effectively raises air quality. Sources of the raw materials are wide; cost is low; the preparation method is simple and scientific; and energy consumption is low.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an environment-friendly filter element material used for an air purifier. Background technique [0002] With the improvement of people's living standards and the increasingly serious air quality, people's requirements for air quality are also getting higher and higher. The peculiar smell in the air environment can have a certain impact on human physical and mental health and work efficiency. The filter element material in the air purifier mainly includes activated carbon with adsorption performance or activated carbon loaded with photocatalyst, which can effectively eliminate non-polar substances of benzene series in the air, but has poor adsorption performance for polar molecule formaldehyde, so the activated carbon filter element is used alone The adsorption effect is very poor, and formaldehyde in the air cannot be removed. Contents of the invention [0003] In ord...
