Technical Field

The invention belongs to the technical field of masks, and particularly relates to a novel nano mask filtering material and a manufacturing method thereof.

Background

With the increasing importance of people on the quality of air environment and indoor air, the environmental standard becomes stricter, and the selected filter material needs to have superior filter performance in order to achieve high-grade air cleanliness. In recent years, various high-efficiency air filtering materials have been greatly developed. The high-efficiency air filtering material has the characteristics of high filtering efficiency, small air flow resistance, high mechanical strength, good uniformity and the like, and can meet the special functional requirements of specific industries on the air filtering material. The existing gauze mask is made of gauze materials, has large aperture, can only intercept large particles in the air, and cannot block PM2.5 and novel coronavirus abused currently; the protective effect is poor, and the comfort level is relatively poor, belongs to outdated product.

Disclosure of Invention

In order to solve the above problems, the present invention provides the following technical solutions: the utility model provides a novel nanometer gauze mask filtering material, includes skin, intermediate level and inlayer, the skin is the water blocking layer, the intermediate level is the filter layer, the inlayer is the hygroscopic layer, the filter layer comprises nanometer film composite.

Further, the diameter of the nano-film is 100-200 nm.

The manufacturing method of the novel nano mask filtering material is characterized by comprising the following steps of:

s1, laying hot air cotton on an internal grounded metal plate;

s2, dissolving the nano-film polymer in a solvent, and stirring until the nano-film polymer is completely dissolved to obtain a nano-film polymer solution;

s3, placing the obtained nano film polymer solution into an injection pump, enabling the injection pump to be connected with a spinning nozzle through a pipeline, enabling the spinning nozzle to be placed above a metal plate paved with hot air cotton, enabling the distance between the spinning nozzle and the metal plate to be 15-35cm, applying high voltage between the spinning nozzle and the metal plate, then carrying out a spinning process, and enabling the spinning solution reaching the spinning nozzle from the injection pump through the pipeline to jet out nano film polymer fibers, wherein the spinning time is 8-30 min;

and S4, collecting the nano-film polymer fibers falling on the surface of the metal plate and compounding the nano-film polymer fibers with hot air cotton to obtain the composite filter material.
