Problems solved by technology

However, the antibacterial sources of existing disposable medical masks rely on the electrostatic antibacterial technology of the melt-blown cloth in the middle layer of the mask. New antibacterial materials have not emerged with the times, and basically follow the technology many years ago, with the ability to filter and block harmful substances. and droplet function, although it can achieve the purpose of reducing the risk of vector transmission, but the antibacterial and antiviral ability is low

Abstract

The invention discloses a disposable medical antibacterial mask. The mask comprises a mask body, a mask inner layer with the periphery sealed, a mask middle layer and a mask outer layer. The mask outer layer is made of a non-woven fabric or an ultrathin polypropylene melt-blown material, and the inner side surface of the mask outer layer is coated with a layer of a bactericidal antiviral material.The bactericidal and antiviral material comprises an aqueous composition and deionized water. The aqueous composition is prepared by the following steps: adding an alcohol ester high-boiling-point solvent coalescing agent into a fluorocarbon modified acrylic polymer in a stirring state, continuously and sequentially adding an organic silicon compound defoaming agent, a sodium tripolyphosphate regulating agent, a potassium sorbate anti-corrosion and anti-mildew agent, a nanometer titanium dioxide coordination modified compound bactericide, a high-molecular polymer polysiloxane solution base material wetting agent, a siloxane polyether modified compound leveling agent and a sodium carboxymethyl cellulose thickener in a stirring state. The disposable medical antibacterial mask is high in sterilization and antiviral capacity.

Description

technical field [0001] The invention belongs to the technical field of protective treatment, and in particular relates to a disposable medical antibacterial mask. Background technique [0002] Medical masks include protective masks, medical surgical masks and ordinary medical masks. Among them, medical protective masks are suitable for wearing when in contact with patients with respiratory infection diseases transmitted by air or close-range droplets in diagnosis and treatment activities; medical surgical masks are mainly used in clean environments with a cleanliness of less than 100,000, working in operating rooms, and nursing Patients with low immune function and body cavity puncture and other operations should wear it; ordinary medical masks can be worn by personnel working in ordinary environments, and their protection level is the lowest compared with the former two. [0003] The main function of disposable medical protective masks is to isolate droplets or blood in th...
