Problems solved by technology

It has been reported that by adding nano-silver on the surface of glass fiber air filter paper to endow glass fiber filter paper with antibacterial properties; Affect the antibacterial effect of filter paper; on the other hand, nano-silver and glass fiber cannot be tightly combined (especially when the content of nano-silver particles increases), and it is easy to fall off during use, thereby affecting the service life of filter paper; in addition, nano-silver is expensive , increasing the quality of the product; therefore, the antibacterial air filter paper on the market is generally expensive and has poor performance

Abstract

The invention discloses antibacterial glass fiber air filtering paper which is prepared from alkali-free glass fiber cotton with the diameter of 3.0-3.5mm, alkali-free glass fibers with the diameter of 0.8-1.0 micron, acrylic emulsion, waterproof emulsion and an antibacterial agent, wherein the mass ratio of the alkali-free glass fiber cotton with the diameter of 3.0-3.5mm to the alkali-free glass fibers with the diameter of 0.8-1.0 micron ranges from (4:1) to (6:1); the antibacterial agent is a mixture of pyrithione substances and nano silver. The invention further discloses a method for producing the filtering paper. The method comprises the following steps: pulping the alkali-free glass fiber cotton to obtain a paper pulp suspension solution; molding the obtained suspension solution to obtain wet paper; spraying the acrylic emulsion, the waterproof emulsion and the antibacterial agent to the wet paper; finally, dehydrating and drying to obtain the product. The antibacterial glass fiber air filtering paper disclosed by the invention has an excellent antibacterial performance, low cost and good use durability.

Description

technical field [0001] The invention belongs to the field of special filter paper, and relates to a filter paper made of glass fiber for filtering air, in particular to a glass fiber air filter paper with antibacterial performance; the invention also relates to a method for producing the filter paper. Background technique [0002] Ordinary air filter paper can only intercept dust, but not bacteria. Therefore, traditional glass fiber air filter paper cannot meet the needs of the bioscience and pharmaceutical industries. [0003] At present, both at home and abroad are committed to the development of glass fiber filter paper with both air filtration capacity and antibacterial properties, and preliminary results have been obtained. It has been reported that by adding nano-silver on the surface of glass fiber air filter paper to endow glass fiber filter paper with antibacterial properties; Affect the antibacterial effect of filter paper; on the other hand, nano-silver and glass...
