preparation example Construction

[0047] The present invention provides a preparation method of the composite detergent builder described in the above technical solution, comprising the following steps:

[0048] Mix carboxyethyl thiosuccinic acid, polyacrylic acid, glacial acetic acid, urea sulfate and water to obtain a composite detergent builder.

[0049] In the present invention, the way of mixing the carboxyethylthiosuccinic acid, polyacrylic acid, glacial acetic acid, urea sulfate and water is preferably stirring and mixing, and the rotating speed of the stirring and mixing is preferably 300-500r / min, more preferably 350-450r / min; the order of mixing is preferably the first mixing of water and polyacrylic acid, the second mixing of adding carboxyethylthiosuccinic acid, and the third mixing of adding glacial acetic acid and urea sulfate. In the present invention, the first mixing time is preferably 15 to 25 minutes, more preferably 20 minutes; the second mixing time is preferably 25 to 35 minutes, more prefe...

Embodiment 1

[0060] In parts by weight, the raw materials for the preparation of composite detergent builders include: 32 parts of carboxyethyl thiosuccinic acid, 5 parts of polyacrylic acid, 5 parts of acetic acid solution (60wt%), 3 parts of urea sulfate and 55 parts of deionized water. share.

[0061] Put polyacrylic acid and deionized water in a high-speed disperser, stir for 20 minutes under the condition of 500r / min, add carboxyethyl thiosuccinic acid and stir for 30 minutes, then add glacial acetic acid and urea sulfuric acid and stir for 20 minutes to obtain a composite washing Auxiliary.

Embodiment 2

[0063] In parts by weight, the raw materials for the preparation of composite detergent builders include: 35 parts of carboxyethyl thiosuccinic acid, 4 parts of polyacrylic acid, 3 parts of acetic acid solution (60wt%), 4 parts of urea sulfate and 54 parts of deionized water share.

[0064] Put polyacrylic acid and deionized water in a high-speed disperser, stir for 20 minutes under the condition of 400r / min, add carboxyethyl thiosuccinic acid and stir for 30 minutes, then add glacial acetic acid and urea sulfuric acid and stir for 20 minutes to obtain a composite washing Auxiliary.

Abstract

The invention provides a compound detergent assistant as well as a preparation method and application thereof and belongs to the technical field of detergent assistants. The compound detergent assistant provided by the invention is prepared from the following components in parts by mass: 30-35 parts of 2-carboxyethylthiosuccinic acid, 5-8 parts of polyacrylic acid, 1-5 parts of glacial acetic acid, 3-5 parts of urea sulfate and 40-65 parts of water. The compound detergent assistant provided by the invention has very good chelating performance and dross dispersion performance upon ions of calcium, magnesium and iron, generation of precipitate in the printing and dyeing finishing processing process and re-contamination of metal salts upon various fibers. In addition, after the soaping of thecompound detergent assistant provided by the invention, a dyed cotton fabric is most approximately neutral; in terms of soaping performance, comparison experiment of the compound detergent assistantprovided by the invention and a dioscorea nipponica acidic soap detergent is implemented, tests show that the compound detergent assistant provided by the invention is good in color fastness and approximate in color change after soaping of black, red and turquoise blue textiles.

Description

technical field [0001] The invention relates to the technical field of washing aids, in particular to a composite washing aid and its preparation method and application. Background technique [0002] With the development of textile, steel, electric power and other industries, how to choose a high-efficiency, energy-saving, time-saving, green and environmentally friendly soaping agent has gradually attracted people's attention. Especially in the active soaping process of textiles, most textiles need to be washed with soaping agent to remove floating color after dyeing. 60~70℃, 5min)→soaping (ordinary soaping agent, 2g / L, 95℃, 10min)→acetic acid neutralization (0.5g / L, 30min)→water washing (hot water, 60~70℃, 5min) →Water washing (cold water, 20-30°C, 5min)→Dehydration and drying.
