Problems solved by technology

However, the existing filter paper is generally weak in strength and poor in high temperature resistance, so when filtering high temperature substances, the filter paper is easily damaged and does not have antibacterial properties, so the application is limited

Abstract

The invention provides a high-strength wear-resistant, high temperature-resistant and antibacterial filter paper. The filter paper comprises, by mass, 40-50 parts of glass fibers, 10-20 parts of traditional Chinese medicinal antibacterial fibers, 5-10 parts of metal fibers, 5-10 parts of ceramic fibers, 8-10 parts of a fiber binder, 3-5 parts of modified nano-carbon, 3-5 parts of modified sepiolite powder, 3-5 parts of modified nakrite, 5-8 parts of a surfactant, 4-6 parts of a dispersant and 5-8 parts of a cross-linking agent. High-adsorption particles are uniformly dispersed in the above mixed fiber structure, so the produced filter paper has the advantages of high strength, good antibacterial property, good temperature resistance and good filtration effect.

Description

Technical field [0001] The invention belongs to the technical field of filter paper materials, and specifically relates to a high-strength wear-resistant, high-temperature and antibacterial filter paper and a preparation method thereof. Background technique [0002] As an effective filter medium, filter paper has been widely used in various fields. Depending on the type of fiber that composes the filter paper, the performance and use of the filter paper are different. There are ordinary filter papers used in general occasions, glass fiber filter papers used at high temperatures, and ultra-clean polypropylene filter papers. With the continuous improvement of filtration requirements, filter paper composed of a single fiber is more and more difficult to meet the requirements of use, so filter paper composed of a combination of multiple fibers came into being. The commonly used fibers in filter paper production include wood fiber, Chemical fiber, glass fiber, etc. However, the exis...
