Abstract

An energy-saving and environment-friendly deinking agent is prepared from the following raw materials in parts by weight: 2-4 parts of acetylene carbon black, 7-9 parts of tetrahydrofuran, 2-6 parts of citric acid, 3-5 parts of a resin copolymer, 4-10 parts of polyacrylamide, 7-11 parts of cationic polyacrylamide, 5-10 parts of sodium alginate, 2-4 parts of polyethylene glycol, 7-9 parts of zirconia whisker, 3-6 parts of borax, 22-30 parts of deionized water, 1-3 parts of a pH regulator, 4-8 parts of acrylic acid and 4-10 parts of polylactic acid. The deinking agent is energy-saving and environment-friendly, has small impact on water quality and environment and has a good deinking effect.

Description

technical field [0001] The invention relates to an energy-saving and environment-friendly deinking agent. Background technique [0002] The deinking agent can separate the waste paper fiber from the ink. The main function of the deinking agent is to destroy the adhesion of the ink to the paper fiber, so that the ink is peeled off from the fiber and dispersed in water. Deinking agents generally have multiple functions such as wetting, penetrating, swelling resin, emulsifying and dispersing. The deinking agent has the following functions: 1. Directly decompose the ink, paint and colorant on the waste paper to achieve the deinking effect; 2. Remove the resin (pitch) in the pulp. However, the existing deinking agents on the market cannot meet people's requirements, and cause great damage to fibers, and may cause certain pollution and damage to water resources. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the problem to be solved by the pres...
