Small molecule dyes adhesion is not strong, dye utilization rate is low, and the aspect of performance such as resistance to migration, heat-resisting and solvent resistant
Shortcoming, and pollution on the environment is serious in use, limits the application in various fields.
Traditional small molecule dyes producing high-molecular can effectively be solved the above problems.High molecular dye is by certain change
Learn reaction and chromophoric group is introduced to a kind of new coloured macromolecule polymer formed on high molecular main chain or side chain, that is, have
High molecular high intensity, easy film forming, solvent resistance, resistance to migration, heat resistance and machinability, but organic dyestuff is to the strong of light
Absorbability and colorful property, show the features such as bright-colored, good color fastness, dye utilization rate are high, nontoxic and easy to use.
In the market, black dyes dosage accounts for the 65% of dyestuff total amount, and black dyes is in weaving, printing and dyeing, leather, painting
There is very important status in the fields such as dress, ink.The early stage black dyes mainly azo dyes as derived from benzidine, has
The advantages of pitch black degree is good, dye-uptake and degree of fixation are high.But producing with carcinogenic intermediate biphenyl amine can be discharged in use, seriously
Environment is polluted, if these dyestuffs are absorbed by the body, can be detrimental to health again and cause serious consequence.Therefore, 70 years last century
Generation black dyes of all kinds as derived from benzidine is in succession disabled.
At present, most of black dyes is that pitch black degree existing for the dispersed black dye of the small molecule of one-component is low, lifted
The subject matters such as power deficiency, fastness are poor and environmental pollution is serious.
Compounded technology is the focus of current dyestuff research, obtains certain progress.Black dyes is obtained by compounded technology.No
But dyestuff pitch black degree and utilization rate can be improved, the dyeability and fastness ability of dyestuff can also be improved.
《Dyestuff and dyeing》(the 4th 10-14 pages of phases of volume 52 in 2015) report the compounding skill of environment-friendly black disperse dyes
Art.It is that raw material is compounded with C.I. disperse violets 93, C.I. disperse blues 291: 1, C.I. disperse oranges 73 and C.I. disperse oranges 44,
Obtain the more superior Compound disperse black dyestuff of dyeability.
《Tianjin textile technology》(the 204th 22-25 pages of phase in 2015) reports compounded technology and dispersed black dye is matched somebody with somebody
Side's design.By compounded formula design gained scattered black ECTT dyestuffs there is good dyeability, compared with the market using compared with
More Disperse Black EX-SFs 300% increase on depth and dyefastness.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of compounding polyurethane-base macromolecule black dye
Material and preparation method thereof, by compounded technology, red, blue, purple, yellow dye is accessed into polyurethane chain.
The present invention is achieved by the following technical solutions:A kind of compounding polyurethane-base macromolecule black dyes of the present invention
