Abstract

The invention relates to the field of air purifying, and discloses an indoor air sterilizing and purifying filter element material and a preparation method. The preparation method comprises the following preparation process with the steps of (1) mixing nanometer titanium dioxide, activated carbon powder, diatomite powder, polyacrylonitrile, polyamide, acetic acid and glycerol to form an emulsion,and performing electrostatic spinning to form a net, so as to obtain a plate-shaped core material; (2) adding nanosilver and polyiodide into silicon sol, so as to obtain bacterium inhibiting and sterilizing powder; (3) adding agar gel and polyvinyl alcohol into the bacterium inhibiting and sterilizing powder to form a gel-shaped matter, impregnating the plate-shaped core material, and drying, so as to obtain the indoor air sterilizing and purifying filter element material. The prepared indoor air sterilizing and purifying filter element material has the advantages that by using the nanosilverand the polyiodide as sterilizing agents, the sterilizing ability is strong, and the safety is good; the formed sterilizing layer can completely coat the core material, so that the effective contact with bacteria is realized; the falling is completely avoided, so that the sterilizing effect is better.

Description

technical field [0001] The invention relates to the field of air purification, and discloses an indoor air sterilization and purification filter element material and a preparation method. Background technique [0002] With the continuous improvement of people's quality of life, people's requirements for health are also constantly improving. At the same time, the environment, water quality and air pollution are becoming more and more serious, so the requirements for air purification are also getting higher and higher. The main pollutants in the air are formaldehyde, benzene, TVOC, nitrite, pathogenic bacteria, viruses, bacteria and other microorganisms. The research and development of air purification materials has become a hot topic in today's social development. [0003] Indoor air purification materials can be divided into four categories: physical purification materials, chemical purification materials, biological purification materials and composite purification materia...
