Description
Technical field
The present invention relates to a kind of preparation method of surface cladding phthalocyanine blue composite pigment, belong to pigment technology field.
Background technology
Copper phthalocyanine does not have pigment performance in itself, it is the intermediate of phthalocyanine color or dyestuff at most.Due to copper phthalein
The crystal grain of cyanines crude product is thick, and purity is again low, so having to pass through surface treatment（Or make pigmentation）Face could be used as
Material uses.The industrially preparing process of copper phthalocyanine is broadly divided into following two by the industrial making method of the thick phthalocyanine blue of raw material：One kind is adjacent
Benzene dinitrile method, another kind are benzene bitter wine-urea methods.
Phthalocyanine blue pigment has the features such as strikingly color, higher tinting strength, tinting power and resistance to strong acid, alkali and solvent resistance.These
Excellent pigment performance, becomes most widely used blue pigment, is popular with the masses of users.Phthalocyanine blue pigment is extensive
Apply in printing ink, plastics, coating and textile printing and dyeing industry etc..
The coloured light of phthalocyanine blue pigment is quite pure, and the transparency is one of three primary colors for printing ink very well.Meanwhile phthalocyanine
Blue pigment also has excellent solvent resistance, this causes it quite to be liked by user.Because it has excellent light fastness, resistance to
Weathering fastness, resistance to migration fastness and heat-resistant stability, so during ink is processed, will not shadow even if temperature is higher
Ring its tinting strength, tinting power and the transparency.
In the plastic, the heat-resistant stability of phthalocyanine blue is fine, can tolerate 300 DEG C of temperature.This causes it to be suitable for plastics
Coloring, especially it also has good easily disperse.In water paint application aspect, phthalocyanine blue pigment can be used for modulating water-based
Intaglio plate flexible ink, wall decoration emulsion paint, pigment printing mill base etc..In addition phthalocyanine blue pigment can be also used for polypropylene fibre,
The coloring of the textile stostes such as terylene, acrylic, nylon, viscose glue, two vinegar fibers.Manufactured textile has very excellent unlubricated friction
Rubbing fastness and fastness to wet rubbing.The product light fastness of 1/3~1/25 standard color depth is up to 7~8 grades.
But at present phthalocyanine blue pigment produce and application process in there are complex process, of high cost, in application system
The problems such as bad dispersibility and its allochromatic colour pigment binding ability are poor and on the high side, therefore, is badly in need of developing a kind of compound face of phthalocyanine blue
Material.
The content of the invention
The technical problems to be solved by the invention：For current phthalocyanine blue pigment, there are technique in production and application process
It is complicated, of high cost, in application system bad dispersibility, with its allochromatic colour pigment binding ability it is poor and on the high side the problem of, there is provided
A kind of preparation method of surface cladding phthalocyanine blue composite pigment.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
（1）Take magnesium chloride, aluminium chloride, zinc chloride add deionized water in be uniformly mixed, add copper phthalocyanine ultrasonic disperse 1~
2h, obtains dispersion liquid；
（2）Take sodium carbonate to add in sodium hydroxide solution to be stirred, and be added dropwise in dispersion liquid, then with sodium hydroxide solution tune
PH to 10~11 is saved, insulation is centrifuged and must precipitated after standing 8~10h；
（3）Precipitation is scattered in deionized water, filter residue is filtered to obtain after 20~24h of hydro-thermal process, residue washing is dried, obtains table
Bread covers phthalocyanine blue composite pigment.
Step（1）The magnesium chloride, aluminium chloride, zinc chloride, the parts by weight of copper phthalocyanine are 28.5~57.0 parts of magnesium chlorides,
26.6~53.2 parts of aluminium chloride, 27.2~54.5 parts of zinc chloride, 200~400 parts of copper phthalocyanines.
Step（1）The deionized water dosage is 5~20 times of copper phthalocyanine quality.
Step（2）The mass fraction of the sodium hydroxide solution is 10%, and the mass ratio of sodium carbonate and sodium hydroxide solution is
1：10.
Step（2）The sodium carbonate amount is the 2.5~10.0% of copper phthalocyanine quality.
Step（3）The hydro-thermal process is 20~24h of hydro-thermal reaction at 120~130 DEG C.
Step（3）The mass ratio of the precipitation and deionized water is 1：20.
Compared with other methods, advantageous effects are the present invention：
（1）The present invention is based on electrostatic interaction, by copper phthalocyanine and the layered hydroxide of hydrotalcite-like compound with opposite charges
Directly assembling obtains laminated nano composition to nano material altogether, and copper phthalocyanine molecule is in monolayer in layered hydroxide interlayer
Vertical arrangement, increases the reaction compartment that the interlamellar spacing of layered hydroxide makes it have bigger, the more activated centres of exposure, increase
With the binding ability of pigment, by being attached to around pigment drop, and then by mechanical barrier mode stable pigments, prevent from storing
During bulk polymerization occurs between particle, improve dispersiveness and compatibility；
（2）Production procedure of the present invention is short, energy consumption is low, consumption of raw materials is few, cost is low, environmental pollution is small, and product may be directly applied to
In the preparation process for printing ink, being not required to can be compound with a variety of pigment by other processing, product of the present invention, the face of its product
Color, mass colour, tinctorial strength, transparency are suitable with the pigment mass of attritor mill method, and chemical stability is high, bright-colored degree
Well, chromatography is complete.
