Abstract

The invention discloses an air purification filter element material for efficiently releasing anion and a preparation method. The preparation method comprises the following steps: mixing and ball-milling an anion release material, an excitation material and an energy conduction material, adding water and a dispersant, and grinding so as to obtain nano mixed powder; hydrolyzing the activated carbonpowder, nano titanium dioxide powder, sodium dodecyl sulfate and tetraethoxysilane with absolute ethyl alcohol so as to obtain a silica sol compound, and pelletizing so as to obtain granules; dispersing the mixed powder, an emulsifier and an adhesive into the absolute ethyl alcohol, spraying to the surfaces of the granules, and drying, thereby obtaining the air purification filter element material. According to the air purification filter element material disclosed by the invention, an anion release agent is solidly adhered to the surfaces of solid granules, so that the contact area with airis greatly increased, anion can be efficiently released into the air for a long time, meanwhile, other substances such as formaldehyde in the air can be adsorbed and degraded, and the purposes of degrading air pollutants and improving air quality can be achieved.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an air purification filter element material and a preparation method for efficiently releasing negative ions. 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. Therefore, the requirements for air purification standards are also getting higher and higher. The main pollutants in the air are formaldehyde, benzene, xylene, bacteria and so on. At present, the widely used purification materials mainly include activated carbon, molecular sieve, nanofiltration membrane and so on. The research on air purification technology and the development and application of air purification materials are closely related to people's life. [0003] In recent years, air purifiers have be...
