Embodiment 1

[0035] The method for preparing the antibacterial and mildew-proof glass fiber composite air filter paper in this embodiment comprises the following steps:

[0036] 1) Pulping: Glass fibers with an average diameter of 0.45um are added with H 2 SO 4 beating and dispersing in the aqueous solution, and control the mass concentration of the slurry to be 3.0%, the beating degree is 48°SR, and the acidity is pH=2.5;

[0037] 2) Wet forming: Dilute the slurry obtained in step 1) to a mass concentration of 0.3%, remove slag, and then add inclined wire forming machine A for wet forming to obtain wet paper;

[0038] 3) Spraying and sizing: the concentration of the antibacterial adhesive solution is 5%, and the antibacterial agent spraying device C is added to the forming net part of the existing manufacturing process, and the wet paper in step 2) is sprayed to make the adhesive evenly distributed on the Between two fiber layers;

[0039] 4) Suction: By means of vacuum suction, use su...

Embodiment 2

[0045] The method for preparing the antibacterial and mildew-proof glass fiber composite air filter paper in this embodiment comprises the following steps:

[0046] 1) Pulping: Glass fibers with an average diameter of 3.2um are added with H 2 SO 4 beating and dispersing in the aqueous solution, and control the mass concentration of the slurry to be 3.5%, the degree of beating is 47°SR, and the acidity is pH=2.3;

[0047] 2) Wet forming: Dilute the slurry obtained in step 1) to a mass concentration of 0.32%, remove the slag, and then add it to inclined wire forming machine A for wet forming to obtain wet paper;

[0048] 3) Spraying and sizing: the concentration of the antibacterial adhesive solution is 3.5%, and the antibacterial agent spraying device C is added to the forming net part of the existing manufacturing process, and the wet paper in step 2) is sprayed to make the adhesive evenly distributed on the Between two fiber layers;

[0049] 4) Suction: By means of vacuum ...

Embodiment 3

[0055] The method for preparing the antibacterial and mildew-proof glass fiber composite air filter paper in this embodiment comprises the following steps:

Abstract

The invention discloses antibacterial mildewproof glass fiber composite air filter paper which comprises an upper glass fiber layer (2) and a lower glass fiber layer (4), wherein an antibacterial layer (3) is arranged between the upper and lower glass fiber layers; a glue spraying layer (1) is compounded on the upper surface of the upper glass fiber layer (2) and an impregnation layer (5) is compounded on the lower surface of the lower glass fiber layer (4); the upper glass fiber layer (2) and the lower glass fiber layer (4) are prepared from glass fiber cotton with the diameter of 0.35-6.5 microns. The invention further discloses a method for moulding and preparing the glass fiber filter paper by a wet process. The glass fiber air filter paper disclosed by the invention is in a multilayered composite structure, and the antibacterial and moistureproof capacity of the paper is enhanced while the filter efficiency of the paper is not affected.

Description

technical field [0001] The invention belongs to the field of silicon-containing inorganic fibers, and relates to a glass fiber air filter material and a preparation method thereof, in particular to a glass fiber air composite filter material with antibacterial and anti-mildew properties for medical devices and a manufacturing method thereof. Background technique [0002] In medical supplies, filters are often seen, some exist to prevent secondary infection, and some are indispensable core components of medical equipment. For example: disposable centrifugal plasma separator, white blood cell filter, precision filter infusion set (medicine liquid filter, air filter), venous blood filter, artificial nose, etc. The core of the filter is the filter paper, which has antibacterial and antifungal properties, which can effectively reduce cross-infection and increase the chance of cure. It can be seen from this that the antibacterial and anti-mildew filter paper has a very broad mark...
