Nano-silver active filter element and preparation method thereof

Abstract

The invention belongs to the technical field of air purification, and particularly relates to a nano-silver active filter element which comprises a filter element body comprising sheet-shaped filter paper formed by stacking multiple layers of composite structures, and the sheet-shaped filter paper sequentially comprises a nano-silver antibacterial layer, a filter layer and a protective layer in the direction from an air inlet surface to an air outlet surface. And the nano-silver antibacterial layer is prepared from phenolic composite fibers immobilized with nano-silver ions, so that the nano-silver ions are combined with the phenolic composite fibers more firmly. The invention further relates to a preparation method of the nano-silver active filter element, the structural diversity of phenolic compounds is utilized, and the nano-silver ions are changed into different shapes, so that the nano-silver ions are combined with the phenolic composite fibers more firmly and are not prone to falling off, the antibacterial performance is enhanced, the nano-silver active filter element can be washed with water for use, and the effects of long-acting antibiosis and high antibacterial performance are achieved.

Description

technical field [0001] The invention belongs to the technical field of air purification, and in particular relates to a nano-silver active filter element and a preparation method of the nano-silver active filter element. Background technique [0002] With the continuous advancement of my country's industrialization process, the problem of environmental pollution has become increasingly prominent, especially the problem of air pollution has seriously affected people's lives and health. Prominent environmental problems have made people increasingly aware of air pollution protection, and air purifiers have become increasingly widely used. However, although the air purifier plays a certain role in filtering the air, it cannot inhibit the growth and reproduction of harmful bacteria in the process of filtering the air on the filter element, and cannot effectively protect personal health. [0003] At present, most of the solutions to inhibit the growth of harmful bacteria on the f...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a kind of nano-silver active filter core, aims to solve the problem that the anti-bacterial agent is not firmly attached and easy to fall off during the use of the filter core of the surface layer spraying antibacterial agent in the prior art, resulting in poor antibacterial performance, and the nano-silver particles that fall off are damaged. Adsorption is harmful to human health; and the filter element with antibacterial agent cannot be washed, resulting in technical problems such as poor water resistance
