Embodiment 1

[0038] A kind of disperse blue dye, is made up of component A, component B and auxiliary agent, and the structural formula of component A is as shown in formula (I), and the structural formula of component B is as shown in formula (II), by mass fraction, The mass fraction of component A is 60-90%, the mass fraction of component B is 5-20%, and the rest are auxiliary agents.

[0039]

[0040]

[0041] The preparation method of the disperse blue dye is as follows: after mixing component A and component B, in the presence of auxiliary agents, use a pulverizing device such as a sand mill or a grinder to micronize the disperse blue dye. Auxiliaries are mainly dispersing leveling agent and water, and may also contain preservatives.

Embodiment 2

[0043] A kind of disperse blue dye, is made up of component A, component C and auxiliary agent, and the structural formula of component A is as shown in formula (I), and the structural formula of component C is as shown in formula (III), by mass fraction, The mass fraction of component A is 60-90%, the mass fraction of component C is 10-30%, and the rest are auxiliary agents.

[0044]

[0045] The preparation method of the disperse blue dye is as follows: after mixing component A and component C, in the presence of auxiliary agents, use a pulverizing device such as a sand mill or a grinder to micronize the disperse blue dye. Auxiliaries are mainly dispersing leveling agent and water, and may also contain preservatives.

Embodiment 3

[0047] A kind of disperse blue dye, is made up of component A, component D and auxiliary agent, and the structural formula of component A is as shown in formula (I), and the structural formula of component D is as shown in formula (IV), by mass fraction, The mass fraction of component A is 60-90%, the mass fraction of component D is 5-25%, and the rest are auxiliary agents.

[0048]

[0049] The preparation method of the disperse blue dye is as follows: after mixing component A and component D, in the presence of auxiliary agents, use a pulverizing device such as a sand mill or a grinder to micronize the disperse blue dye. Auxiliaries are mainly dispersing leveling agent and water, and may also contain preservatives.

[0050] According to the disperse dyes prepared in Examples 1-3, the washing fastness, perspiration fastness, sublimation fastness and water fastness of the disperse blue dye composition all meet the requirements. The time-temperature dependence and pH depend...

Abstract

The invention provides a disperse blue dye and its application, belonging to the field of dye chemical industry. It solves the problems of existing disperse blue XF (C.I.blue284) production danger, heavy pollution, poor reduction resistance during dyeing, and calcium and magnesium ions have a great influence on the vividness of dyeing. It is a disperse blue dye, which is characterized in that, It includes at least component A, and the structural formula of component A is shown in formula (I): the present invention has the advantage of being able to replace Disperse Blue XF (C.I.blue284).

Description

technical field [0001] The invention belongs to the field of dye chemical industry, in particular to a disperse blue dye and its application. Background technique [0002] Dyes refer to a class of organic compounds that can make other substances obtain bright and firm colors. Since the pigments used today are all artificially synthesized, they are also called synthetic dyes. Dyes and pigments are generally self-colored compounds that can make other substances obtain bright and firm colors in molecular or dispersed state. [0003] Disperse Blue XF (C.I.blue284) is a very bright and important disperse dye with high dyeing fastness, but it is dangerous in production, heavy in pollution, and poor in reduction resistance during dyeing. Calcium and magnesium ions have a great influence on the vividness of dyeing. [0004] The chemical formula of Disperse Blue XF (C.I.blue284) is as follows: [0005] [0006] in, It involves dinitration reaction, which is very dangerous and ...
