Problems solved by technology

[0003] Among them, C.I. Disperse Yellow 23 was banned due to the suspected reductive cracking of the carcinogenic aromatic amine 4-aminoazobenzene. Since the European Union listed C.I. Disperse Yellow 23 as a prohibited dye, the search for a substitute for C.I. Disperse Yellow 23 has been launched in China. However, no breakthrough results have been achieved, and the development of substitutes for disperse yellow RGFL is still a relatively large subject.

Embodiment 1

[0025] A low-temperature disperse yellow dye composition, consisting of the following raw materials in mass percent:

[0026] The monomer A is 55% by mass, the monomer B is 12% by mass, the monomer C is 10% by mass, and the balance is additives.

[0027] The preparation method of the above-mentioned low-temperature disperse yellow dye composition comprises the following steps: weighing each monomer and auxiliary agent in proportion, adding them to a dispersing kettle, adding water and beating to obtain a slurry, transferring the slurry to a liquid fine grinder for pulverization, It is then transferred to a sand mill for grinding for 40 hours. After grinding, it is stirred and ultrasonicated for 5 minutes, and then sent to a microwave drying room for drying. At the same time, it is sprayed with a dust-proof agent to obtain a finished product.

Embodiment 2

[0029] A low-temperature disperse yellow dye composition, consisting of the following raw materials in mass percent:

[0030] The monomer A is 45% by mass, the monomer B is 25% by mass, the monomer C is 5% by mass, and the balance is additives.

[0031] The preparation method of the above-mentioned low-temperature disperse yellow dye composition comprises the following steps: weighing each monomer and auxiliary agent in proportion, adding them to a dispersing kettle, adding water and beating to obtain a slurry, transferring the slurry to a liquid fine grinder for pulverization, It is then transferred to a sand mill for grinding for 50 hours. After grinding, it is stirred and ultrasonicated for 5 minutes, and then sent to a microwave drying room for drying. At the same time, it is sprayed with a dust-proof agent to obtain a finished product.

Embodiment 3

[0033] A low-temperature disperse yellow dye composition, consisting of the following raw materials in mass percent:

[0034] The monomer A is 40% by mass, the monomer B is 10% by mass, the monomer C is 4% by mass, and the balance is additives.

[0035] The preparation method of the above-mentioned low-temperature disperse yellow dye composition comprises the following steps: weighing each monomer and auxiliary agent in proportion, adding them to a dispersing kettle, adding water and beating to obtain a slurry, transferring the slurry to a liquid fine grinder for pulverization, It is then transferred to a sand mill for grinding for 50 hours. After grinding, it is stirred and ultrasonicated for 5 minutes, and then sent to a microwave drying room for drying. At the same time, it is sprayed with a dust-proof agent to obtain a finished product.

Abstract

The invention provides a low-temperature dispersion yellow dye composition and a preparation method thereof and relates to the field of synthesis dyes. The yellow dye composition is composed of, by mass, 40-60% of a monomer A of which the chemical formula is described as the specification, 10-30% of a monomer B of which the chemical formula is described as the specification, 4-12% of a monomer C of which the chemical formula is described as the specification, and the balanced being an additive. The yellow dye composition has equal tone as C.I. dispersion yellow 23 while other comprehensive performances are higher than those of the C.I. dispersion yellow 23. In addition, the preparation method is simple.

Description

technical field [0001] The invention relates to the field of synthetic dyes, in particular to a low-temperature disperse yellow dye composition and a preparation method thereof. Background technique [0002] Disperse dyes are a class of non-ionic dyes with low water solubility. It was first used for the dyeing of acetate fiber, known as acetate dye. With the development of synthetic fibers, nylon and polyester have appeared one after another, especially polyester, because of its high alignment, less fiber voids, and strong hydrophobicity, it is necessary to expand the fiber with a carrier or under high temperature and thermal melting, so that the dye can enter Fiber and dyed. Therefore, new requirements are put forward for dyes, that is, dyes with better hydrophobicity, certain dispersibility and sublimation resistance are required. At present, the disperse dyes used for dyeing polyester fabrics in printing and dyeing processing basically have these properties, but due to ...
