Abstract

The invention discloses glass fiber air filter paper with an antibacterial property. The glass fiber air filter paper comprises alkali-free glass fibers of which the diameter is 0.1-0.5 micron, alkali-free glass fibers of which the diameter is 1.0-2.0 microns, alkali-free glass fibers of which the diameter is 5-7 microns, glass fiber filter paper manufactured from PET (polyethylene terephthalate) polyester fibers, and a pyrithione derivative antibacterial layer which is attached to the surface of the filter paper. The invention also discloses a method for preparing the glass fiber air filter paper, comprising the following steps of: (1) selecting raw materials according to a mixing ratio; (2) pulping and dispersing the raw materials to obtain a slurry; (3) diluting the slurry and adjusting the PH value; (4) removing residues from the slurry obtained in the step (3), and preparing wet paper by using a wet method forming; (5) dehydrating the wet paper obtained in the step (4); (6) passing the wet paper obtained in the step (5) through a gum solution of a pyrithione derivative; and (7) drying the wet paper obtained in the step (6). The glass fiber air filter paper is excellent in antibacterial and air filtration performances, and is wide in application field.

Description

technical field [0001] The invention relates to a glass fiber air filter paper, in particular to a fiber air filter paper with antibacterial properties and a preparation method thereof. Background technique [0002] Glass fiber air filter paper is made of glass fiber as the main raw material, and is generally made by wet forming process. It has the characteristics of uniform fiber distribution, large dust holding capacity, small resistance, and high strength. It is an ideal air filter material. [0003] Antibacterial paper refers to loading antibacterial agents on paper as a carrier. Antibacterial agents are usually divided into inorganic antibacterial agents and organic antibacterial agents. Inorganic antibacterial agents mainly refer to the preparations loaded with silver, zinc, copper and other nanoparticles with antibacterial ability on the paper. Organic antibacterial agents mainly refer to the preparations containing sulfonate and polycyclohexane biguanide Formulatio...
