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

Abstract

The invention belongs to the technical field of air purification, and particularly relates to a nano-silver active filter element, including a filter element body, which includes a sheet-shaped filter paper composed of a multi-layer composite structure, and the sheet-shaped filter paper is sequentially arranged from the air inlet surface to the air outlet surface. It includes a nano-silver antibacterial layer, a filter layer and a protective layer. The nano-silver antibacterial layer is prepared from phenolic composite fibers loaded with nano-silver ions, so that the nano-silver ions can be more firmly combined with the phenolic composite fibers. The invention also relates to the preparation method of the nano-silver active filter element, which uses the structural diversity of phenolic compounds to change the nano-silver ions into different shapes, so that the nano-silver ions are more tightly combined with the phenolic composite fibers, and are not easy to fall off and strengthened. Antibacterial performance is guaranteed, and it can be washed and used to achieve long-lasting antibacterial and strong antibacterial performance.

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 air pollution problem, which has seriously affected people's lives and health. Prominent environmental problems have made people's awareness of air pollution protection increasingly stronger, and air purifiers have become more 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 human health. [0003] At present, most of the solutions to inhibit the growth of harmful bacteria ...
