Abstract

The invention relates to a filter material and a manufacturing method thereof. The filter material comprises a first mixed layer obtained by mixing natural bamboo fibers and 4080 and then performing thermoforming, and also comprises a polytetrafluoroethylene microporous membrane attached to the first mixed layer by hot-pressing. The filter material further comprises a second mixed layer obtained by mixing natural bamboo fibers and 4080 and then carrying out thermoforming, and the polytetrafluoroethylene microporous membrane is clamped between the first mixed layer and the second mixed layer. The manufacturing method of the filter material comprises the following steps: 1, feeding one end of a rolled first mixed layer between an upper roller and a lower roller of a hot press; 2, placing oneend of a rolled polytetrafluoroethylene microporous membrane on the surface of one end of the first mixed layer; and 3, starting the hot press, and tightly attaching the polytetrafluoroethylene microporous membrane to the surface of the first mixed layer along with the rotation of the upper roller and the lower roller. The filter material has the characteristic of good filtering effect.

Description

Technical field [0001] The invention relates to a filter material and a manufacturing method thereof. Background technique [0002] Chinese Patent Document No. CN 107283963 A disclosed on October 24, 2017 an air filter cloth containing graphene materials and bamboo fibrils. The air filter cloth includes a HEPA layer, a graphene-based polyurethane fiber layer, and a bamboo fibril layer. A graphene-based polyurethane fiber layer is arranged under the HEPA layer, and a bamboo fibril layer is arranged under the graphene-based polyurethane fiber layer. The bamboo fibril layer is pressed from bamboo fibrils; the graphene-based polyurethane fiber layer is graphene / nanocrystalline cellulose / Polyaniline / thermoplastic polyurethane composite fiber woven. The production cost of this kind of air filter cloth is relatively high, and the filtering effect is not ideal, which needs to be improved. Summary of the invention [0003] The purpose of the present invention is to provide a filter mate...
