Abstract

The invention belongs to the technical field of air purification, and relates to a filter net with the formaldehyde purification function and a preparation method of the filter net. The filter net iscomposed of a pre-filter layer, a formaldehyde filter layer, a formaldehyde secondary-filter layer and a protective layer which are stacked in sequence, wherein the pre-filter layer is composed of a polyester fiber mesh; the formaldehyde filter layer is composed of a honeycomb carrier and a formaldehyde purification composite material; the formaldehyde secondary-filter layer is composed of a laminated sheet boron silicon microfiber mesh; and the protective layer is composed of a fabric mesh, a synthetic fiber mesh, a glass fiber mesh, a metal microporous honeycomb mesh or a plastic microporoushoneycomb mesh. The filter net provided by the invention not only can realize the quick adsorption of formaldehyde, but also can eliminate the formaldehyde through a chemical reaction, and the wholepurification process exhibits the characteristics of rapidness, stability, and high efficiency. The formaldehyde removal process is not constrained by light conditions in the environment, the formaldehyde can be continuously eliminated under conditions of low light or no light, and the filter net is suitable for large-scale promotion and application, and has great market prospects.

Description

technical field [0001] The invention belongs to the technical field of air purification, and relates to a filter screen with formaldehyde purification function and a preparation method thereof. Background technique [0002] With the increasingly serious environmental pollution, people's health has been greatly threatened. As a high incidence of indoor air pollution, the invisible killer represented by formaldehyde in the newly renovated new home is seriously affecting people's health, and it is urgent to purify the air in the new home. People have tried a variety of measures to deal with the "formaldehyde killer". Many companies have launched targeted products, such as air purifiers, ozone sterilizers, activated carbon bags, etc., and air purifiers are undoubtedly the most effective products. . [0003] At present, the mainstream air purifiers on the market mainly include adsorption air purifiers, chemical decomposition air purifiers and electrostatic integrated air purifi...
