Sugar-coated haw string type antibacterial and antiviral filter screen and manufacturing process thereof

Abstract

The invention relates to the field of purification filter screens, in particular to a sugar-coated haw string type antibacterial and antiviral filter screen and a manufacturing process thereof. The sugar-coated haw string type antibacterial and antiviral filter screen comprises raw filaments, a titanium dioxide photocatalyst covering layer and a porous coating layer; by preparing the raw filaments and immersing the raw filaments in a self-developed titanium dioxide photocatalyst, then drying treatment, weaving and covering of a porous coating layer are carried out, so that the antibacterial and antiviral filter screen is obtained, excellent antibacterial and antiviral effects are achieved under photocatalysis, photocatalytic activity of titanium dioxide is maintained, photocorrosion of titanium dioxide to filter screen protofilaments is avoided, shedding and loss are avoided, and the cost is low while long-term effective use is realized.

Description

technical field [0001] The invention relates to the field of purification filter nets, in particular to a candied haws string-type antibacterial and antiviral filter net and a manufacturing process thereof. Background technique [0002] Most of the existing filters do not have antiviral function, but filters with antibacterial function, such as the use of silver ions and the use of natural antibacterial agent catechin, have their own shortcomings, such as the high cost of silver ions, and the natural antibacterial agent The antibacterial effect is not good, and in order to pass the national standard test, it is generally used in excess, but in actual production, the amount used is insufficient due to cost issues, so the use effect cannot meet the actual demand. Contents of the invention [0003] Aiming at the current situation of the above-mentioned prior art, the present invention provides a candied haws string type antibacterial and antiviral filter and its manufacturing...
