High efficiency and low foam environment-friendly type scouring agent and preparation method thereof

Abstract

The invention provides a high efficiency and low foam environment-friendly type scouring agent and a preparation method thereof, wherein the scouring agent comprises: 15-25% by weight of dodecyl diphenyl ether sodium disulfonate, 5-15% by weight of C12-16 seconary Alkane Sulphonate Sodium, 15-25% by weight of alkyl polyglucoside, 10-150% by weight of isomeric alcohol ethoxylates, and the balance being water. The concrete steps for preparing the scouring agent, comprising: adding water into a mixture of dodecyl diphenyl ether sodium disulfonate and C12-16 seconary Alkane Sulphonate Sodium, and then mixing the mixture for dissolving; and (2) adding alkyl polyglucoside and isomeric alcohol ethoxylates into the mixture obtained in the step (1), and then uniformly mixing. The product is used as a green environmental protection printing and dyeing auxiliary agent with the advantages of simple technology, environment-friendly formula and excellent performances.

Description

technical field

[0001] The invention relates to a pretreatment auxiliary agent for textile printing and dyeing, in particular to a high-efficiency, low-foaming and environment-friendly scouring agent. Background technique

[0002] The scouring agent is obtained through a certain proportioning method. It is a compound that mainly has a washing effect and has synergistic effects such as penetration, emulsification, dispersion, and complexation, including surfactants and appropriate additives. The scouring agent plays a very important role in the process of retreating, boiling and bleaching. The alkali-resistant concentration of most scouring agents is generally below 100g / L, while the concentration of supplementary alkali for debonding, boiling, and bleaching is above 200g / L. Caustic soda and scouring agent can only be prepared separately. In this way, although the concentration of alkali can be controlled, the concentration of scouring agent cannot be accurately controlled, ...
