Alkaline air filter material containing active carbon

Abstract

The invention provides an alkaline air filer material containing active carbon. The alkaline air filter material comprises an outer layer and an inner layer, wherein the outer layer has a filter material, and is blended napped filter cloth that is blended and weaved from polymer fibers, the blended napped filter cloth has two layers, the filter material is attached between the two layers of blended napped filter cloth, and the filter material is prepared from the following materials: active carbon, kieselguhr, a porous adsorption material, nano-zinc oxide, nanometer titania, gelatin and sodiumcarboxymethylcellulose; the inner layer is composed of two layers of non-woven fabric and an alkaline compound clamped between the two layers of non-woven fabric, and the inner layer and the outer layer are compounded through needling or spunlace. Compared with the prior art, the alkaline air filer material containing active carbon has the following beneficial effects that features of high efficiency of filtering, high clogging capacity and low airflow resistance are realized, the sterilization and disinfection effect on the environment for which the material is used is achieved, and therefore the living environment is healthier.

Description

technical field [0001] The invention is an alkaline air filter material containing activated carbon, which belongs to the field of air filter materials. Background technique [0002] Masks have a certain filtering effect on the air that enters the lungs. When respiratory infectious diseases are prevalent, wearing a mask has a very good effect when working in a polluted environment such as dust. Most of the current masks are gauze masks. The structure of gauze masks The tightness with the human face is very poor. Many small particles that are extremely harmful to us will enter the respiratory tract to the lungs through the gap between the mask and the face. Its filter materials are generally some mechanical fabrics. The only way to increase the dust blocking efficiency is to increase the thickness, and the negative effect of increasing the thickness is to make the user feel a lot of breathing resistance and feel uncomfortable.

[0002] Masks have a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent, when working in dusty and other polluted environments, wearing a mask has a very good effect. Most of the current masks are gauze masks, and the structure of gauze masks The tightness with the human face is very poor. Many fine particles that are extremely harmful to us will enter the respiratory tract to the lungs through the gap between the mask and the face. Its filter materials are generally some mechanical fabrics. The only way to increase the dust blocking efficiency is to increase the thickness, and the negative effect of increasing the thickness is to make the user feel a lot of breathing resistance and feel uncomfortable.
