Description
Technical field
The present invention relates to plastic-coated industries more particularly to a kind of pigment preparations mill base and preparation method thereof.
Background technique
Paste pigment is a kind of commercial prod of the pigment production producer after deep processing.Due to being easily dispersed, save
Ink, the milling time of coating material production factory and production cost, ought to can be by the welcome of the industries such as coating.But so far,
Other than aluminum paste, the pulpous state material supplied in the market is very few, some paste pigments are to be added with dry powder pigment in sand mill
Work is dispersed into thick mill base, rather than is made with the water squeezing technique of pigment filter cake.Under the shape heat that market economy reaches its maturity, coating
Requirement of the factory to pigment factory yield and quality is also higher and higher, and market competition aggravation, the only product of high quality just can be popular.
Though the non-new things of paste pigment, development space should say it is not small, especially it is poisonous and harmful contain a huge sum of money
The inorganic pigment of category, such as lead chromate yellow, molybdate red, zinc yellow, should slurrying shape commodity as early as possible, go out to avoid in production and use
Existing employee's intoxicating phenomenon.For solving the above problems, pigment is slurried pigment, can be described as one really has direction
The measure of property.In addition to water paint can be with other than paste pigment, solvent-based paints industry is also required to paste pigment, as long as corresponding
Base-material changes all kinds of paint oils into.In addition, rubber industry can also be coloured with paste pigment, plastic industry is used to be increased containing mutually application
The paste pigment for moulding agent can be very convenient, will become essential colorant.
Therefore, it is necessary to research and develop a kind of easy dispersion for meeting the needs of market, low dirt, environmentally friendly slurry pigments.
Summary of the invention
Goal of the invention：In order to solve the problems, such as existing market paint, the present invention provides a kind of low dirt, environmental protection, high dispersive
The pre-dispersed property dispersible pigment color paste of many advantages, such as property, high transparency, high-luster.
To achieve the goals above, the present invention takes following technical scheme：
A kind of pigment preparations mill base, the pigment preparations mill base includes following components in percentage by weight：
Preferably, the pigment is：One of carbon black, pigment scarlet powder, phthalocyanine blue, phthalocyanine green, forever solid orange and iron oxide red or
It is several.
Preferably, the resin is：Water-based acrylic resin, acrylate, oil alkyd resin and linseed oil alkyd tree
One or more of rouge.
Preferably, the dispersing agent is：One of octyl phenol polyoxyethylene ether, polypropylene glycol and ethanol amine are several
Kind.
Preferably, the solvent is：In isopropanol, dioctyl phthalate, propylene carbonate and polypropylene glycol
One or more.
Preferably, the defoaming agent is：One or more of polyethers, C7-C9 higher alcohols and organic silicon modified by polyether.
A kind of preparation method of pigment preparations mill base, which is characterized in that include the following steps：
(1) base-material prepares：It is spare resin, defoaming agent, dispersing agent, solvent have been weighed；
(2) by the pigment after precipitating after filter press, the pigment filter cake that solid content is 20-80% is formed；
(3) solid content 20%-80% pigment filter cake and base-material are invested in kneader in proportion, are sufficiently mixed,
Heating, until base-material enters pigment particle surface and becomes thick slurry, and by water discharge except thickness slurry；
(4) kneader is recycled remaining trace water in thickness slurry to be discharged to get pigment preparations mill base is arrived.
It preferably, is 40-60 minutes in the time of kneader mixing in step (3).
Preferably, in step (3), after being sufficiently mixed, it is warming up to 50-100 DEG C.
Preferably, in step (4), remaining micro-moisture is discharged under conditions of vacuum degree is 0.8-1.5Mpa.
The beneficial effects of the invention are that：Pigment preparations mill base of the invention is easily dispersed, water-tolerant, adhesive force are good,
Tinctorial property is excellent, can be widely used for solvent-based paints industry, rubber industry, chemical fibre coloring, plastic industry；Of the invention pre- point
The preparation method simple process of dispersed pigment mill base, low dirt, environmental protection, pigment is completely dispersed, and has saved ink, coating material production factory grinds
Time consuming and production cost.

Be centrifuged 30 minutes under the revolving speed of min, observation sedimentation layering the case where centrifuge tube top do not observe color difference be judged as very well, from
Heart pipe top slightly color difference but the judge without layering are preferably, centrifuge tube top is it is observed that obvious color difference but existing and clear liquid do not occur
Be slightly layered be judged as it is general, have clear liquid be obviously layered be judged as difference；
2, it separately takes sample, after the solvent of quality such as being added, stirs evenly, stand, and respectively at 6 months and 12 months,
Observation sedimentation situation, test result are as follows：
1 pigment preparations performance test results table of table
The results show that the dispersibility for the pigment preparations that embodiment 1-3 is obtained is preferable, and it is not added with dispersing agent and disappears
