preparation example Construction

[0055] Also, see image 3 , image 3 Another schematic flowchart of the preparation method of the composite material layer provided in the embodiment of the present application. like image 3 As shown, the composite filter layer is laminated and arranged on the support layer, so that before the step of obtaining the composite material layer, it also includes:

[0056] 103. Connect the second protective layer to the first protective layer, so as to clamp the nanofiber filter layer between the first protective layer and the second protective layer, to form a composite filter layer.

[0057] Wherein, the second protective layer is cotton woven fabric or polypropylene spun-bonded non-woven fabric. The areal density of the polypropylene spunbonded nonwoven fabric ranges from 10 grams per square meter (g / m2) to 30 grams per square meter (g / m2). It should be noted that the second protective layer may be a hydrophobic polypropylene spunbonded nonwoven fabric or a hydrophilic polyp...

Abstract

The embodiment of the invention provides a preparation method of a composite material layer, the composite material layer and a mask. The preparation method comprises the following steps: preparing ananofiber filter layer on a first protective layer by adopting an airflow spinning process, connecting the second protective layer with the first protective layer, so that the nanofiber filter layer is clamped between the first protective layer and the second protective layer and a composite filter layer is formed, and laminating the composite filter layer on the support layer to obtain the composite material layer. The embodiment of the invention provides the preparation method of the composite material layer, the composite material layer and the mask. The nanofiber filter layer on the firstprotective layer is prepared by adopting an airflow spinning process, and the composite material layer is used as the core filter layer of the mask, so that the mask can be used for many times after being effectively disinfected and sterilized by alcohol, high temperature, ultraviolet rays, fumigation, boiling and the like, the productivity and the use cost are greatly saved, and the waste and thepost-treatment pollution are reduced.

Description

technical field [0001] The application relates to the field of mask preparation, in particular, to a method for preparing a composite material layer, a composite material layer and a mask. Background technique [0002] Under the sudden outbreak of the new coronavirus in early 2020, N95 masks and medical masks were out of stock, and masks were hard to find in the market. The filter layer of most masks in the market uses electret cloth, that is, the method of corona discharge is used to charge the ordinary melt-blown cloth without increasing the resistance to improve the capture and filtration of particulate matter. [0003] The electrostatic charge of the mask will be lost or neutralized as time goes by during use, resulting in a decrease in the filtering effect. This is also the fundamental reason why the mask has a valid period at this stage. In addition, treatment methods such as alcohol, high temperature, ultraviolet light, fumigation, and boiling can sterilize and steri...
