Embodiment Construction

[0045] (1) Preparation of terpolymer

[0046] Proportion (unit: kg): [total amount: 100kg]

[0047] Maleic anhydride: 10-20

[0048] Acrylic acid: 10-25

[0049] Acrylamide 3-10

[0050] Ammonium persulfate: 0.05-3% of monomer weight

[0051] Distilled water: balance.

[0052] Operating process:

[0053] Clean the reaction kettle, pump in distilled water, add maleic anhydride and stir for 15 minutes to make it completely dissolve. (Do not heat up, just see that the solution is transparent and there is no white insoluble matter), then add acrylamide to the reaction kettle and stir to dissolve for 10 minutes. Close the feeding port, suck in acrylic acid, and stir for 5 minutes. Note: Do not mix iron ions into the monomer solution, keep the upper reactor at normal temperature; in order to make the monomer drop evenly later, keep the stirring running until the monomer drops completely. Dissolving ammonium persulfate: Dissolve ammonium persulfate in cold distilled water. (...

Abstract

The invention discloses an efficient environment-friendly neutral soaping agent for a reactive dye and a preparation method for the efficient environment-friendly neutral soaping agent. The efficient environment-friendly neutral soaping agent is prepared by terpolymer, ammonium dihydrogen phosphate, triethanolamine, 2,3-bis-laurate group sodium tartrate, an organic silicon defoamer and water, wherein the terpolymer is prepared by maleic anhydride, crylic acid, acrylamide, ammonium persulfate and distilled water. By the soaping agent and the preparation method, a reactive dyeing object is prevented from being subjected to a dye-fiber covalent bond breaking reaction under an alkaline high-temperature soap boiling condition; a hydrolysis dye is migrated from the dyeing object to a bath in an accelerated manner, cleaning efficiency is improved, and the optimal firmness is realized; the rigidity of a soap bath is corrected, so that the dyeing object can be well cleaned in low-rigidity water; the hydrolysis dye which is washed out is prevented from being dyed again; time and water are saved, the cost is reduced, and the efficiency is improved; and a jet dyeing machine cannot generate more foams.

Description

Technical field: [0001] The invention relates to a preparation method of a high-efficiency and environment-friendly neutral soaping agent for reactive dyes. Background technique: [0002] The existing soaping agent has unsatisfactory working effect due to unreasonable formula. Invention content: [0003] The object of the present invention is to provide a kind of active dyes with reasonable formula and good effect, high-efficiency and environment-friendly neutral soaping agent and its preparation method. [0004] Technical solution of the present invention is: [0005] A kind of active dye high-efficiency environment-friendly neutral soaping agent is characterized in that: it is made up of following composition by weight percentage: [0006] Terpolymer: 40-60% [0007] Ammonium dihydrogen phosphate: 12-16% [0008] Triethanolamine: 2-6% [0009] 2,3-Dilaurate Sodium Tartrate 3~4% [0010] Silicone defoamer: 0~2% [0011] water: surplus; [0012] Wherein the terpoly...
