Zusammenfassung:The invention provides a washing-process waste paper deinking agent. The washing-process waste paper deinking agent consists of the following three non-ionic surfactants in percentage by weight: 30-50% of fatty alcohol-polyoxyethylene ether, 20-30% of fatty alcohol polyoxyethylene polyoxypropylene ether and 30-40% of polyoxyethylene fatty acid. The washing-process waste paper deinking agent provided by the invention is prepared by compounding three surfactants which do not contain alkylphenol ethoxylates (APEO) and sodium alkyl benzene sulfonate, is safe and environment-friendly, has good permeation effects and emulsification and washing effects, has low-foam and foam inhibition functions, and also has good dispersion and precipitation prevention performance. The waste paper deinking agent is an environment-friendly waste paper deinking agent specifically suitable for washing-process waste paper deinking technologies.
