Description
Technical Field
The invention belongs to the field of dye chemical industry, and particularly relates to a disperse black dye composition.
Background
The black dye commonly used in the market at present is disperse black ECT 300%, and the corresponding formula patent is a Chinese patent invention disperse azo dye mixture of CN1113941C published on 7, 9 and 2003.
The existing black dye disperse black ECT 300% formula must contain a disperse violet 93 (formula IIIa) and is matched with a dye shown in formula IV for toning, wherein Y on a benzene ring on the left side of the formula IV1And Y2All are Cl and are yellow in color if the benzene ring Y on the left of formula IV1And Y2One of which is substituted with Cl and the other with H, is orange in color. (see the specification of the inventive disperse azo dye mixture of China, CN1113941C, published on 7/9/2003 in formulas IIIa and IV).
However, according to the updated list of sensitizable chemicals in textiles and leather products by the ECHA (European chemical administration) official website for 5 months, 4 new disperse dyes were listed, including disperse Violet 93, in addition to the deactivatable disperse dyes in OETX-TEX. Therefore, the disperse violet 93 is used as an sensitizing disperse dye, so that 300% of the disperse black ECT is not suitable for being continuously used in the field of textiles, and a product dyed by 300% of the disperse black ECT is easy to cause allergy to consumers, so that the potential safety hazard is greatly increased. Therefore, it is very urgent to find a 300% alternative to black ECT.
Disclosure of Invention
The invention aims to solve the problems in the prior art and provides a disperse black dye composition.
The purpose of the invention can be realized by the following technical scheme: a disperse black dye composition is characterized by comprising a component A, a component B, a component C and an auxiliary agent, wherein the component A is selected from at least one compound shown in a formula (I), the component B is selected from at least one compound shown in a formula (II), the component C is selected from at least one compound shown in a formula (III), and the formulas (I) to (III) have the following structures:
n in formula (I) represents 1 or 2;
r in the formula (II)1Represents Cl or Br, R2Represents CH3Or C2H5；
R in the formula (III)3Is represented by C1-C4Alkyl radical, R4Represents H or CN.
Preferably, the mass fraction of the component A is 0.5-50%, the mass fraction of the component B is 0.5-40%, the mass fraction of the component C is 0.5-30% and the balance is auxiliary agents in terms of mass fraction.
Preferably, component A has a structural formula shown in formula (I-1):
preferably, component B is selected from at least one of the dye compounds represented by the formulae (II-1) and (II-2):
preferably, component C is selected from at least one of the dye compounds represented by the formulae (III-1) to (III-5):
preferably, the mass fraction of the component A is 13%, the mass fraction of the component B is 24.82%, the mass fraction of the component C is 7.13%, and the balance is auxiliaries.
Preferably, the structural formula of the component A is shown as a formula (I-1), the component B is formed by mixing (II-1) and (II-2) according to the proportion of 3:7, and the structural formula of the component C is shown as a formula (III-2);
compared with the prior art, the invention has the following advantages:
1. the component A is orange, the component B is blue, the component C is red, and black is obtained by blending three colors of orange, blue and red, so that the traditional orange-violet-blue color matching is separated. In addition, the disperse violet 93 in the existing formula of 300% of black dye disperse black ECT is listed as an sensitizing disperse dye, and the red component C is adopted to replace the disperse violet, so that the sensitizing problem is solved, and the component C has the advantages of low cost and good compatibility with an orange component A and a blue component B. Particularly, the compatibility among the formulas (I-1), (II-2) and (III-2) is extremely high.
2. In order to be compatible with the component A and the component B, the component C red dye must be a medium-temperature dye, and the traditional disperse red 50 is a low-temperature dye and has poor compatibility with the component A orange dye and the component B blue dye.
The component C is a medium-temperature reddish jade dye, and has good compatibility with the component A orange dye and the component B blue dye. And the component C red dye has low cost.
3. The ortho-position of N on the left benzene ring of the component C is nitro, so that the depth of the dye and the energy level of the dye are increased, the component C is reddish jade, and the energy level of the dye is SE type dye.
If the ortho position of N on the left benzene ring of the component C is Cl, the color of the dye is light red, and the energy level of the dye is E-type dye (namely low-temperature dye), the dye can not meet the requirement of compatibility with the component A orange dye and the component B blue dye, and can not meet the requirement of blending with the component A orange dye and the component B blue dye into black.
4. The three components of the black disperse dye have high compatibility, so that the black disperse dye has a good uniform dyeing effect, and can realize quick dyeing.
