AI Technical Summary

Problems solved by technology

First of all, after the acrylic darkening agent treats the cotton fabric, it feels hard
Secondly, silicone-based darkening agents, especially darkening agent complexes containing quaternary ammonium salt compounds and silicones, are difficult to form a stable emulsified system during emulsification, especially when the pH value fluctuates to a certain extent. The stability of the system is not very good. In addition, while solving the stability of the emulsified system, it is also necessary to ensure the deepening effect, which is difficult

preparation example Construction

[0050] The preparation method of described Bola organic silicon quaternary ammonium salt comprises the following steps:

[0051] a) Under protective atmosphere conditions, add allyl glycidyl ether to tetramethyldisiloxane to obtain epoxy double-capped F 2 D. 2 ;

[0052] b) the epoxy double head F 2 D. 2 Mix and heat with octamethylcyclotetrasiloxane to carry out chain extension reaction to obtain epoxy-terminated silicone oil ETSO;

[0053] c) mixing and heating the epoxy-terminated silicone oil ETSO and meglumine, and performing an amination reaction to obtain the silicone block silicone oil PTSO;

[0054] d) Mixing and heating the organosilicon block silicone oil PTSO and a quaternizing agent to perform a quaternization reaction to obtain a Bola-type organosilicon quaternary ammonium salt.

[0055] In the present invention, under protective atmosphere conditions, allyl glycidyl ether is added to tetramethyldisiloxane to obtain epoxy double-capped F 2 D. 2 .

Abstract

The invention provides a Bola organosilicon quaternary ammonium salt darkening agent emulsion. The present invention reverses the emulsion system by adopting Bola organosilicon quaternary ammonium salt, penetrating agent, and non-ionic / anionic emulsion combination, and prepares a stable emulsion system with a double-layer shell, and the inner shell is wrapped with Quaternary ammonium ions, carboxylate ions on the outer shell, with non-ionic surfactants and penetrants in the middle, can provide stable intervals to avoid system instability, and are suitable for high temperature, high electrolyte, high pH and high shear force Under the same conditions, it can remain stable; the nonionic surfactant of polyoxyethylene ether itself has excellent compatibility with other nonionic surfactants, and it can be compatible with polyvinylpyrrolidone. Polyoxyethylene ether A nonionic surfactant, polyvinylpyrrolidone, can form a stable inner shell. At the same time, the double-shell quaternary ammonium silicone emulsion can show a very excellent darkening effect.

Description

technical field [0001] The invention belongs to the technical field of fabric treatment agents, and in particular relates to a Bola organosilicon quaternary ammonium salt darkening agent emulsion and a preparation method thereof. Background technique [0002] With the development of the economy, the requirements for environmental protection at home and abroad are getting higher and higher, and the production cost of the dyeing factory is increasing. It is imperative to reduce the amount of dye to reduce the cost. In order to achieve the same dyeing depth, darkening agents came into being. Especially the post-finishing darkening agent has the most practical value. [0003] In the prior art, darkening agents are divided into silicone-based darkening agents and acrylate-based darkening agents, most of which are obtained through emulsion polymerization. [0004] Applicant Pan Minghua filed an invention patent application CN201610507142.6 in 2016, which disclosed a silicone dark...
