Abstract

The invention discloses a high-strength fluid separation medium which is obtained by adding a hyperbranched polymer into a multi-fiber-layer material obtained by covering and depositing multiple single fiber layers, each single fiber layer comprises glass microfibers and other fibers, and the mass percentage of the glass microfibers with the fiber diameter distribution range within 0.5-2 microns in the glass microfibers is 70%; the other fibers comprise one or more of bicomponent fibers, water-soluble fibers, sea-island fibers and cellulosic fibers; a terminal group of the hyperbranched polymer contains a structural unit shown in a formula I, R is a perfluorocarbon chain with the carbon number smaller than or equal to 10 or a-[Si-O-Si] n-or a-SiH2-group, or R contains an aliphatic group, a metallic soap group, a paraffin group, a hydroxymethyl group, a pyridine group or a hydrocarbon chain with the carbon number of 8-18. According to the fluid separation medium, the filter paper strength is improved while the air permeability is not reduced and the transmittance is not influenced.

Description

technical field [0001] The invention relates to the technical field of filter materials, in particular to a high-strength fluid separation medium. Background technique [0002] At present, fluid filtration and separation media are widely used in all walks of life. Usually, fluid filtration and separation media are composed of fiber nets. To achieve the purpose of separation or purification. Fluid filtration separation media is currently widely used in various filter elements or filters. [0003] However, the current filter media generally have the problem of insufficient strength and cannot meet various application conditions. There are studies to improve the strength by compounding or adding adhesives without affecting the transmittance, but this method will lead to a decrease in air flow, which will increase the energy consumption of the filter equipment during operation and reduce the service life of the filter medium. [0004] Therefore, there is a need for a new type...
