Air filter paper and preparation method thereof

Abstract

A type of air filter paper and a preparation method therefor. The preparation method includes the following steps of: (1) preparing a piece of bottom-layer paper; (2) preparing a dispersion mixed solution of a carbon nanomaterial; and (3) arranging the bottom-layer paper on the former, and conveying the dispersion mixed solution of a carbon nanomaterial onto the former, wherein the dispersion mixed solution of a carbon nanomaterial is filtered and formed on the bottom-layer paper, and then carrying out sizing and drying to obtain the air filter paper.

Description

technical field

[0001] The invention relates to the technical field of nanomaterials, in particular to an air filter paper and a preparation method thereof. Background technique

[0002] Small particles in the air can deposit in the lungs and even the blood circulation system of the human body, causing respiratory diseases or thrombus; in addition, due to the large specific surface area of ​​small particles, they can absorb a large amount of toxic substances such as organic gases, viruses, bacteria, etc., further harming the human body. Health is a threat. With the development of society and the popularization of health knowledge, people pay more and more attention to the harm of fine particle pollution in the air. In recent years, air filtration products have gradually become a necessity of life. The requirements have also been greatly increased.

[0003] The smaller the fiber diameter of the filter material, the smaller the particle size for removing particles in the air...
