Description
Technical field
The invention belongs to the preparation field of organic pigment, a kind of nanoscale copper phthalocyanine pigments that is directly synthesized
Method.
Technical background
The miniaturization always pigment manufacturer of pigment (organic pigment and inorganic pigment) granule needs to solve for a long time
Key problem in technology and a difficult problem.So that pigment has a wide range of applications characteristic, pigment production producer needs preparation
Going out tinting strength, tinting power high, good dispersion, good stability in using medium, and full pigment bright in colour, this is just
Require pigment granule is tiny and narrow particle size distribution.But owing to granules of pigments is the most tiny, its surface can be the biggest, more
Easily again can be condensed into hard bulky grain, make application performances such as tinting strength, tinting power, dispersibility, particle diameter distribution etc. big
Big decline, this problem always perplexing pigment manufacturer.
At present, manufacturing field at pigment, the method tackling this problem mainly has following several:
(1) polytype surface conditioning agent is added to stop or to subtract less granular gathering；
(2) mix certain specific isomeric compound to reach to stop or reduce to coagulate with the crystal growth affecting pigment
Poly-generation；
(3) raw by crystal formation being modified or controlled by post processing means such as solvent method, acid pasting, ball-milling methods
Long, reach suppression flocculation and occur；
(4) take the grinding and processing technology of machinery and physics, manufacture attritive powder, increase pressure as used
Contracting power and frictional force carry out the high pressure homogenizer pulverized or use grinding of media material.
Owing to introducing surface conditioning agent and other isomeric compound in said method (1) and (2), to some to product
The special occasions that product purity has higher requirements is the most inapplicable, and divides with the pigment particle size of both of these approaches manufacture
Cloth wider (i.e. size is uneven) is also significant deficiency.
Said method (3) is to introduce again substantial amounts of organic solvent or concentrated sulphuric acid or grinding aid after pigment synthesizes specially
Agent carries out pigmentation process to pigment, makes crystalline pigment and granular size meet application requirement, this method shortcoming
The step pigmentation treatment process that has been many, and produce a large amount of waste liquid simultaneously, process in this way and be also difficult to make
Go out nano level pigment.
Said method (4) is after drying by physical method at pigment, uses substantial amounts of mechanical energy to reach super
Finely divided purpose.This method easily causes microstrain, defect, causes the poly-of high surface energy at fresh surface
Collection, its particle size distribution is to be evenly distributed, less application in pigment manufactures.
And can be used for manufacturing ultra-fine and that dispersive property is good organic pigment currently without effective technological means.
Summary of the invention
In order to realize above-mentioned technical purpose, the present invention provides a kind of side being directly synthesized nanoscale copper phthalocyanine pigments
Method, it can meet producer and to pigmenting power, dispersibility in media as well and stablize and full color
Requirement.
For achieving the above object, the concrete technical scheme that the present invention takes is: one is directly synthesized nanoscale phthalein
The method of cyanines copper pigment, comprises the technical steps that: first operation, weighs following material by weight: pole
Property organic solvent 270-280 part, phthalic nitrile 40-60 part, carbamide 8-15 part, ammonium molybdate 0.3-1 part, chlorine
Change cuprous；Wherein, the weight portion of Cu-lyt. is the 1/8-1/5 of phthalic nitrile；
Second operation work, is uniformly mixed the material weighed on supersonic generator；The most ultrasonic
Condition is: frequency 80-95HZ, and the time is 30min-1h；
Three process, is placed in microwave reactor microwave heating to 180-190 DEG C by the material of mix homogeneously,
Material reacts, and constant temperature keeps 20min, and reaction terminates, and obtains the primary product of reaction；The frequency of microwave
For 2.45GHZ-3GHZ；
4th procedure, by primary product take out, in the environment of being placed in 0-10 DEG C cool down, toward cool down after preliminary
Add PH=12 in product, temperature is the water of 90-100 DEG C, and primary product is stirred washing standing point
Layer, takes off a layer material；Repeat this process, until the PH=7-8 of lower floor's material；Then lower floor's material is carried out
Azeotropic distillation, steams remanent polarization organic solvent and water, obtains filter cake；Described filter cake methanol is dried after cleaning,
I.e. obtain nanoscale copper phthalocyanine pigments.
The technical scheme improved as the present invention, described polar organic solvent is that boiling point is more than the polarity of 200 DEG C and has
Machine solvent.
The technical scheme improved as the present invention, described polar organic solvent is Nitrobenzol or dimethyl sulfoxide.
The beneficial effects of the present invention is:
By ultrasonic and two kinds of reaction bonded technology of microwave, it is directly synthesized and produces nano-level pigment.Its technological principle
When being to utilize ultrasonic cavitation produce mechanically and chemically effect, make mass transfer, heat transfer, chemical bond fracture effect strong
Changing, microwave heating can make chemical substance be brought rapidly up within tens of seconds to a few minutes simultaneously, makes the face being immediately generated
Material granule is tiny to be had uniformly, particle diameter about 3-4nm, narrow particle size distribution, it is to avoid secondary nucleation, the most ultrasonic sky
Change effect can be stablized the granulation tissue of nanosized and be assembled.Synthetic reaction terminates, and recycles azeotropic dehydration technology,
Remove the moisture in suspension pigment, it is to avoid granules of pigments produces hard agglomeration, after being then peeled off organic solvent
It is dried, so that it may the most once obtain the hydrophobic micropowder nano-level pigment of soilless sticking.
