Abstract

The invention relates to the technical field of air filter material preparation, and specifically discloses a filter material for an air purifier and viscose-based activated carbon fibers loaded with the filter material for an air purifier. The filter element material for an air purifier comprises the following components in parts by weight: 30 to 50 parts of diatomite; 30 to 50 parts of bentonite; 10 to 20 parts of magnesium hydroxide; 10 to 20 parts of carbon material; 5 parts of sodium alginate ~10 parts; In addition, it also contains 1~5 parts of antibacterial agent. The filter element material for an air purifier of the present invention has excellent formaldehyde and toluene removal capabilities, and the ability to purify bacteria in the air. In particular, the invention provides a viscose-based activated carbon fiber loaded with a filter element material for an air purifier; it perfectly combines the filter element material for an air purifier with the viscose-based activated carbon fiber viscose-based activated carbon fiber, and has stronger purification capacity of the air.

Description

technical field [0001] The invention relates to the technical field of air filter material preparation, in particular to a filter material for an air purifier and viscose-based activated carbon fibers loaded with the filter material for an air purifier. Background technique [0002] Indoor air pollution refers to the pollution caused by excessive harmful substances in indoor air. For example, newly decorated interiors and newly purchased furniture will cause formaldehyde in the indoor air to exceed the standard, thereby affecting human health. With the increasing requirements of people on the living environment, people pay more and more attention to the formaldehyde pollution in the air. However, one of the ways to remove formaldehyde from the air indoors is through an air purifier. In the process of purifying the air in the air purifier, the filter element material is the core of purifying the air. The filter element material has poor adsorption capacity for formaldehyde ...
