Embodiment 1

[0050] (1) Add methacryloyloxyethyltrimethylammonium chloride, 2-methacryloyloxyethylphosphorylcholine and ammonium persulfate to deionized water respectively to obtain a solution, methacryloyloxyethyl The molar ratio of trimethylammonium chloride, 2-methacryloyloxyethylphosphorylcholine and ammonium persulfate is 100:100:5. Immerse the polypropylene melt-blown cloth in the prepared solution, and then take it out Press between the pads to remove excess solution before drying at 80°C.

[0051] (2) Place the dried material in step (1) in a glow discharge radio frequency oxygen plasma with a gas flow rate of 100 sccm, a chamber pressure of 40 Pa, and a discharge power of 100 W for 5 minutes, then wash with deionized water, and dry at 80°C. That is, the sterilized antifouling melt-blown cloth is obtained.

Embodiment 2

[0053] (1) Add methacryloyloxyethyltrimethylammonium chloride, 2-methacryloyloxyethylphosphorylcholine and 2-hydroxyl-2-methyl-1-phenylmethanone respectively In deionized water, a solution was obtained, methacryloyloxyethyltrimethylammonium chloride, 2-methacryloyloxyethylphosphorylcholine and 2-hydroxy-2-methyl-1-phenylmethanone The molar ratio is 100:100:5. The polypropylene melt-blown cloth is immersed in the prepared solution, then taken out and pressed between the pads to remove excess solution, and then dried at 80°C.

[0054] (2) Place the dried material in step (1) in a photochemical reactor. The light source used is an ultraviolet lamp with a power of 500W. The material is polymerized under ultraviolet light for 1 hour, then washed with deionized water, and dried at 80°C. A sterilized anti-fouling melt-blown cloth was obtained.

Embodiment 3

[0056] In this example, the sterilizing and antifouling melt-blown cloth material was prepared according to the same method as in Example 1, the only difference being that polylactic acid was used instead of polypropylene melt-blown cloth in step (1) to obtain a sterilized and anti-fouling melt-blown cloth.

Abstract

The invention discloses a bactericidal and antifouling melt-blown cloth and a processing technology thereof. The melt-blown cloth is immersed in a mixed solution of a quaternary ammonium salt monomer, a zwitterionic monomer and an initiator, and then dried; the dried melt-blown cloth is arranged The polymerization reaction is carried out under the excitation source of the polymerization reaction, washed and dried to obtain a sterilized antifouling melt-blown cloth. The method of the present invention is simple to operate, only one step is needed to quickly realize the simultaneous occurrence of material activation and modification on simple equipment, and it is easy to industrialize, and the prepared sterilizing and antifouling melt-blown cloth has higher sterilization and long-term efficacy and stability, and is easy to use It is safe and can be used in various fields, such as surgical gowns, masks, isolation gowns, masks and gloves, wall coverings, bed sheets and bedspreads, clothing, etc.

Description

technical field [0001] The invention relates to the field of antibacterial functional materials, in particular to a bactericidal and antifouling meltblown cloth and a processing technology thereof, belonging to the technical field of organic composite functional materials. Background technique [0002] There are a variety of pathogenic microorganisms in life, which pose a great threat to people's life and health. Among them, for the current new type of coronavirus, although relevant scholars are already actively looking for relevant therapeutic drugs and vaccines, the best way is to take personal protection, such as wearing a mask when going out. Melt-blown cloth is the core raw material for bacterial and virus filtration of protective equipment such as masks and protective clothing. Its fiber diameter can reach 1-5 microns. The most immediate barrier to infection. [0003] At present, the melt-blown cloth in the domestic and foreign markets is mainly made of polypropylene...
