Active carbon filtering paper

Abstract

The invention discloses active carbon filtering paper which is prepared from the following raw materials in parts by mass: 50-100 parts of wood pulp fibers, 80-100 parts of Lyocell fibers, 50-100 parts of viscose fibers, 250-400 parts of active carbon, 50-100 parts of anthracite filter media, 1-10 pars of polyurethane acrylic resin, 2-10 parts of polyurethane resin, 2-8 parts of chloride vinyl resin, 3-5 parts of polyvinyl alcohol, 1-2 parts of a sodium carboxymethylcellulose emulsifier, 2-3 parts of a stabilizer, 1-3 parts of a solidifier and 2-3 parts of an initiator. The active carbon filtering paper is high in wet anti-tension index and excellent in filtering effect and has the advantages of long service life, simple production technology, convenience in control, low cost and the like.

Description

technical field [0001] The invention relates to the technical field of detecting filter paper, in particular to a dry strength agent for 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.
