Problems solved by technology

[0005] The preparation process involved in the currently used bio-based pigment adsorbent, that is, the treatment process for biological substrates is relatively complicated, requiring multi-step activation and modification, and some biological substrates need to be used for activation treatment and grafting reaction. A large amount of chemical reagents, it is difficult to completely remove the residues of chemical reagents, which will inevitably cause pollution to the environment, and also cause the problem of high production costs of bio-based pigment adsorbents
Therefore, the achievements of bio-based pigment adsorbents are mostly in the laboratory research stage, and have not been widely used in the market.

Abstract

The invention relates to a treatment liquid of a pigment adsorbent and an application of the treatment liquid. The treatment liquid of the pigment adsorbent comprises a water-based acrylate polymer, a polyamine compound and / or a cationic etherifying agent, wherein the molar ratio of the polyamine compound to the water-based acrylate polymer is 1:(0.1-10), the molar ratio of the cationic etherifying agent to the water-based acrylate polymer is 1:(0.1-8); and the water-based acrylate polymer is formed by polymerization of monomer A, wherein the monomer A is one or more selected from a group consisting of methyl methacrylate, butyl acrylate, acrylic acid and hydroxyethyl acrylate. The adsorption efficiency of the treatment liquid is high; the prepared adsorbent can be widely applied to solving the cross color problem when fabrics are mixed and washed in daily life and the problems that the treatment of wastewater containing pigment in the industry is difficult, the cost is high and the emission causes the environment pollution; and the adsorbent has simple production processes and low cost, and is beneficial for industrial production.

Description

technical field [0001] The invention relates to the technical field of daily chemical industry, in particular to a treatment solution of a pigment adsorbent and its application. Background technique [0002] Dye is an organic compound that can make other substances obtain bright and stable colors. While its appearance has improved people's living standards and brought huge economic benefits, it has also caused serious environmental pollution, difficult treatment, and high treatment costs in dyeing and finishing wastewater. series of questions. [0003] The use of dyes includes four processes of pretreatment, dyeing, printing, and finishing in printing and dyeing processing, and the wastewater generated is the main source of dye wastewater. Improper treatment of these waste water can easily damage the water body, increase the total phosphorus and nitrogen content in the water, make the water eutrophication, and at the same time consume dissolved oxygen, destroy the water eco...
