Abstract

The invention discloses a preparation method of a degradable photocatalyst antibacterial mask, and relates to the technical field of masks, and the preparation method comprises the following steps: (1) preparing a degradable nose bridge strip; (2) preparing a mask body; and (3) mounting the degradable nose bridge strip on the mask body. The method has the advantages that the degradable nose bridgestrip and melt-blown cloth are both made of polylactic acid as raw materials and have degradability, all the raw materials of the degradable nose bridge strip have a synergistic effect, so that the prepared degradable nose bridge strip is relatively good in rebound rate and strength, and when the ratio of polylactic acid to silicone oil to titanium dioxide is changed, the prepared nose bridge strip cannot be formed, and the rebound rate and the strength cannot meet the requirements. All the raw materials in the melt-blown cloth have a synergistic effect, so that the prepared melt-blown clothis relatively good in filtering efficiency and antibacterial effect, and when the mass ratio of polylactic acid to electret master batch to nano zinc oxide is changed, the filtering performance and antibacterial performance of the melt-blown cloth are reduced.

Description

technical field [0001] The invention relates to the technical field of masks, in particular to a preparation method of a degradable photocatalyst antibacterial mask. Background technique [0002] Masks are an important line of defense against respiratory infectious diseases and can reduce the risk of new coronavirus infection. Reasonable selection and use of masks can effectively prevent virus infection. Generally, masks on the market can only block bacteria and viruses on the outside of the mask at most, and cannot decompose harmful substances. After about 30 minutes, an ordinary mask will become a source of infection, endangering human health. [0003] Photocatalyst is currently a safe and clean purification material in the world, and is widely used in medicine, food, cosmetics and other fields in Europe, America, Japan, Korea and other regions. It has strong sterilization, deodorization, anti-virus, and air-purifying properties. Due to the self-cleaning function of th...
