Problems solved by technology

[0003] In the existing technology, filter paper is a very important kind of porous material. Its physical properties, chemical properties and filtration performance not only restrict the application range of filter paper, but also affect its filtering effect.
The activated carbon filter paper on the market is installed in the water purifier. Although it can filter to a certain extent, it has the problem of poor water filtration, which leads to slow water filtration and is not easy to use.

Abstract

The invention relates to filter paper for a water purifier. The filter paper is prepared from, by weight, 46-50% of activated carbon, 42-43% of hardwood pulp, 9-9.8% of polyester fibers, 1-1.8% of glass fibers, 0.04-0.12% of cationic polyacrylamide, 0.1-0.3% of alkyl ketene dimer, 0.5-0.9% of polyamide epichlorohydrin and 8-10% of acrylate resin. The filter paper is a filter material with a porous network structure, which is prepared by taking plant fibers and glass fibers as carriers and adding activated carbon powder, chemical fibers and functional aids into paper pulp, and has good interception, adsorption and filtration effects on residual chlorine and organic impurities in water. On the basis that the filtering performance of the filter paper is guaranteed, the water filtering speed of paper sheets is increased, and the filter paper has high economic popularization value.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to a water purifier filter paper and a preparation method thereof. Background technique [0002] The traditional water purification method mainly uses the porosity of activated carbon particles to process tap water by making activated carbon columns or activated carbon particle filter layers outsourced with PP cotton. In recent years, due to the miniaturization and convenience requirements of household water purifiers, developed countries such as Europe and the United States have begun to develop special activated carbon filter paper for water purifiers. [0003] In the existing technology, filter paper is a very important kind of porous material, and its physical properties, chemical properties and filtration performance not only restrict the application range of filter paper, but also affect its filtering effect. Activated carbon filter paper on the market is installed...
