Embodiment 1

[0034] In percent by weight, weighed according to the following proportions: octyl phosphate 40%, dodecyl dihydroxyethyl betaine 30%, alkyl glycoside 10%, AES 20%, defoamer 0.1%; the above raw materials Add it into the mixing tank, stir at room temperature for 30-60 minutes, until all raw materials are completely mixed, then add 30% NaOH solution, adjust pH = 7-8, and finally add softened tap water to dilute to an aqueous solution with a solid content of 50% , that is, the rapid alkali-resistant penetrating agent Ⅰ is obtained, its appearance is a colorless transparent liquid, and its alkali resistance can reach 150g NaOH / l.

Embodiment 2

[0036] In percent by weight, weighed according to the following proportions: octyl phosphate 40%, lauryl amidopropyl betaine 30%, alkyl glycoside 10%, AES 20%, defoamer 0.1%; put the above raw materials into the mixing kettle , stirred at room temperature for 30-60 minutes, until all raw materials are completely mixed evenly, then add 30% NaOH solution, adjust pH = 7-8, and finally add softened tap water to dilute into an aqueous solution with a solid content of 50%, which is obtained Rapid alkali-resistant penetrating agent II, its appearance is colorless transparent liquid, and its alkali resistance can reach 180g NaOH / l.

Embodiment 3

[0038] In terms of weight percent, it is weighed according to the following ratio: octyl phosphate 40%, dodecyl dimethyl-2-hydroxypropyl sulfobetaine 30%, alkyl glycoside 10%, AES 20%, defoaming Add the above raw materials into the mixing tank, stir at room temperature for 30-60 minutes, until the raw materials are completely mixed, then add 30% NaOH solution, adjust the pH = 7-8, and finally add softened tap water to dilute into An aqueous solution with a solid content of 50% can be used to prepare rapid alkali-resistant penetrating agent III. Its appearance is a transparent colorless liquid, and its alkali resistance can reach 200g NaOH / l.

Abstract

The invention discloses a fast alkali-resistant penetrating agent and a preparation method thereof. The fast alkali-resistant penetrating agent comprises the following components by weight percentage: octyl phosphate 10-60%, amphoteric surfactant 10-30%, alkanes 5-20% of sugar anhydride, 10-30% of fatty alcohol polyoxyethylene ether sulfonate, and 0.1-0.5% of defoamer. Add the above-mentioned raw materials into the mixing tank according to the required ratio, stir evenly, add NaOH solution to adjust the pH=7~8, and finally add water to dilute to obtain the rapid alkali-resistant penetrant. The penetrant prepared by the present invention has an alkali resistance of up to 300g / l NaOH, and has good penetration, emulsification, and washing properties under neutral to strong alkaline conditions, and does not contain APEO, is easy to degrade, and is suitable for printing and dyeing. various processes.

Description

technical field [0001] The invention relates to a fast alkali-resistant penetrating agent used in the technical field of fabric printing and dyeing and a preparation method thereof. Background technique [0002] As the name implies, the penetrant is a substance that plays a penetrating role and has fixed hydrophilic and lipophilic groups, which can be aligned on the surface of the solution and can significantly reduce the surface tension. The broad concept of penetrant refers to a class of chemicals that can help substances that need to penetrate to penetrate substances that need to be penetrated. In industry, surfactants (which can be anionic or nonionic) or organic or inorganic solvents are generally used. [0003] Penetrants are generally divided into two categories: nonionic and anionic. Non-ionic ones include JFC (fatty alcohol polyoxyethylene ether), JFC-1, JFC-2, JFC-E, etc.; anionic ones include fast penetrant T, alkali-resistant penetrant OEP-70, alkali-resistant p...
