Problems solved by technology

[0005] However, by adding antibacterial and antiviral particles to the fabric raw materials to impart antibacterial properties to the fabric, there are problems such as limited load capacity, poor binding fastness, and inability to maximize its antibacterial effect; the method of synthesizing functional particles on the surface of the fabric has a reaction time. Long, complicated reaction process, high production cost

Abstract

The invention provides an antibacterial and antiviral mask and a preparation method thereof. The antibacterial and antiviral mask sequentially comprises a barrier protective layer, an antibacterial and antiviral layer, a filter layer and a skin-friendly layer from outside to inside. Wherein the antibacterial and antiviral layer is a melt-blown non-woven fabric modified by nano cuprous oxide, and the nano cuprous oxide is loaded and fixed on a fiber surface layer of the melt-blown non-woven fabric through an in-situ reaction. The method specifically comprises the following steps: pretreating a melt-blown non-woven fabric, sequentially padding the pretreated melt-blown non-woven fabric in an alkaline solution, a copper source solution and a reduction solution, controlling the liquid carrying rate of the pretreated melt-blown non-woven fabric, finally putting the pretreated melt-blown non-woven fabric in a solvent reaction medium, and carrying out in-situ reaction in a high-temperature environment to obtain the nano-cuprous oxide. According to the antibacterial and antiviral mask, through the dual functions of the blocking protective layer and the antibacterial and antiviral layer, the effects of blocking germs, inhibiting bacteria and killing bacteria can be achieved in a short time, so that the mask has the long-acting antibacterial and antiviral functions; and the mask is good in washability, the antibacterial effect is not changed after the mask is continuously washed for 50 times, the practicability is high, and the requirements of the market on the mask function aspect are greatly met.

Description

technical field [0001] The invention relates to the technical field of protective masks, in particular to an antibacterial and antiviral mask and a preparation method thereof. Background technique [0002] As a kind of sanitary protective equipment, masks are worn on the mouth and nose to filter the air entering the mouth and nose, so as to block harmful gases, odors, droplets, viruses and other substances. Especially since the outbreak of the new crown pneumonia epidemic, masks have become a necessity for people's daily travel. Wearing a mask can not only block bacteria and dust in the air, and effectively curb the prevalence of respiratory infectious diseases; it can also effectively block pathogenic microorganisms from infiltrating the human body, which plays an important role in preventing the spread of the new crown pneumonia virus and protecting people's health. [0003] At present, most of the commonly used masks on the market are ordinary masks made of breathable fa...
