Activated carbon filter paper

Abstract

The invention discloses activated carbon filter paper which consists of the following raw material formula components in parts by weight: 50-100 parts of wood pulp cellulose, 80-100 parts of polyurethane, 50-100 parts of polystyrene fiber, 250-400 parts of activated carbon, 50-100 parts of anthracite filtering materials, 1-10 parts of polyurethane acrylic resin, 2-10 parts of epoxy resin, 2-8 parts of vinyl chloride-vinyl acetate resin, 3-5 parts of polyvinyl alcohol, 1-2 parts of a sodium carboxymethylcellulose emulsifier, 2-3 parts of magnesium stearate, 1-3 parts of a curing agent and 2-3 parts of an initiator. The activated carbon filter paper disclosed by the invention has the advantages of excellent wet tensile index and filtering effect, longer service life, simple production process, convenience in control, lower cost and the like.

Description

technical field [0001] The invention relates to a filter paper, in particular to an activated carbon filter paper. Background technique [0002] Nowadays, the society has higher and higher requirements for the quality of urban tap water, and it is required to meet the standard of direct drinking. The traditional water purification method mainly uses the high adsorption performance of the porosity of activated carbon particles to make activated carbon columns or activated carbon particle filter layers. Outsourcing means non-woven fabrics to treat tap water. In recent years, due to the miniaturization and convenience requirements for household water purifiers, developed countries such as Europe and the United States have begun to produce special activated carbon filter paper for water purifiers.

Problems solved by technology

[0003] Activated carbon filter paper is a kind of filter material with a porous network structure, which is made by adding activated carbon powder, chemical fiber and functional additives to pulp with plant fiber as the carrier. It has good retention of residual chlorine and organic impurities in water. Adsorption and filtration, but the price of the existing activated carbon filter paper is too high, the waste of activated carbon in the production engineering increases the production cost of the product
