Abstract
The invention discloses an environment-friendly high-temperature direct-injection disperse black dye ink and a preparation method thereof, wherein the environment-friendly high-temperature direct-injection disperse black dye ink is prepared from the following raw materials in parts by mass: 10-40 parts of high-temperature disperse dye, 10-40 parts of dispersing agent, 10-50 parts of organic solvent, 10-60 parts of water, 0.05-0.5 part of preservative and 0.01-0.05 part of defoaming agent; the Zetasperse series special dispersing agent is produced by dispersing agent air chemical industry. Mixing high-temperature disperse dye, a dispersing agent, water, a preservative and a defoaming agent into a mixture, sanding and dispersing, nano-filtering after sanding, adding an organic solvent into color paste and uniformly mixing, namely, directly spraying and dispersing the black dye ink at high temperature. The high-temperature direct-injection dispersion black ink has the characteristics of high saturation, bright color and less salting out; the conductivity is low, and the service life of the spray head is prolonged; the forbidden aromatic amine content is extremely low, and the method is suitable for clothes textiles; the ink has good dispersion stability and long storage time.
Description
Technical Field
The invention relates to an environment-friendly high-temperature direct-injection disperse black dye ink and a preparation method thereof.
Background
The present commercially available dispersion inks for textiles are classified into imported inks and domestic inks. The most important defects of the system are that the salt content is high, the conductivity of the produced dispersion ink product is high, the high salt content not only influences the stability of the system, the ink is easy to salt out, but also has great influence on the color of the product, and the reaction has dirty color, dark color light and insufficient saturation.
At present, only the dispersion ink produced by DuPont and Hensman can achieve the characteristics of high saturation, bright color and less salting out. Due to the technical monopoly, the selling price is always high, and the use of the low-consumption environment-friendly dye by printing and dyeing enterprises in China is severely restricted.
Most of the high-temperature direct-injection disperse black dye inks in the current market are forbidden to have excessive aromatic amine content, and if the high-temperature direct-injection disperse black dye inks are used for clothing textiles, the carcinogenic risk of consumers in China is greatly increased, so that the environment-friendly high-temperature direct-injection disperse black dye ink is researched.
With the continuous improvement of the mechanical manufacturing technology in China, the research and development of ink-jet printing equipment become more mature, and powerful equipment support is provided for printing and dyeing enterprises to achieve the aims of saving energy and reducing consumption by using dispersed ink. At present, due to the monopoly status of the series of products abroad, the ink-jet digital textile printing machine is usually sold in a binding sale mode, so that the research and development of the series of products in China are greatly limited.
The high-temperature direct-injection disperse dye ink is mainly applied to digital printing, and the digital printing has the following advantages compared with the traditional printing and dyeing:
1. the whole printing process is digitalized, so that the printed product has variability and flexibility in design and production;
2. the printed design can be modified at will on the computer until the customer is satisfied. In the traditional printing, once a sample of a designer is determined, the second change and design are difficult to carry out, and the flexibility and the market strain are lacked;
3. digital printing belongs to digital control, has an accurate color expression mode, and a designed manuscript can be stored at any time and has good reproducibility. The traditional printing method has no good number for detail treatment, and a large amount of reducing agent pollution and dye waste exist in the 'embossing' process required by the traditional printing method;
4. the digital printing and dyeing belongs to a green printing and dyeing mode, water and color paste do not need to be prepared in the spraying process, waste dye liquor and color paste do not exist, and the noise is low. The traditional printing and dyeing has large demand for water, the produced waste liquid, waste water and waste pulp have great pollution to the environment, and the treatment of the waste water needs a large amount of investment, so that the printing cost is greatly increased.
Because of the huge defects of the traditional printing and dyeing, the method is not suitable for the development mode of modern industry, a new industrial-grade digital printing process is gradually replaced, and various inks more suitable for industrial-grade digital textile printing machines, in particular novel inks used by precision work nozzles such as Beijing porcelain and the like, are also needed.
Disclosure of Invention
The invention provides environment-friendly high-temperature direct-injection disperse dye ink and a preparation method thereof, and solves the problems of poor quality such as high conductivity, easy salting out, insufficient saturation, forbidden exceeding of aromatic amine and the like of most of the disperse direct-injection inks on the market at present.
In order to achieve the above object, the first environment-friendly high-temperature direct-injection disperse black dye ink adopted by the invention has the technical scheme that: the material consists of the following raw materials in parts by mass:
wherein the dispersant is a special dispersant, and the special dispersant is at least one selected from Zetasperse 2500, Zetasperse3100, Zetasperse 3400, Zetasperse3600, Zetasperse 3700 and Zetasperse3800 of air chemical products;
the high-temperature disperse black dye is formed by compounding high-temperature disperse blue, high-temperature disperse orange and high-temperature disperse red, wherein the high-temperature disperse blue accounts for 35-70% of the high-temperature disperse black dye by mass, the high-temperature disperse red accounts for 5-25% of the high-temperature disperse black dye by mass, and the high-temperature disperse orange accounts for 10-40% of the high-temperature disperse black dye by mass.
In order to achieve the above purpose, the second environment-friendly high-temperature direct-injection disperse black dye ink adopted by the invention has the technical scheme that: the material consists of the following raw materials in parts by mass:
