Description
Technical field
The present invention relates to staining technique field, it particularly relates to a kind of colouring compositions, preparation method
And dyeing.
Background technology
, mainly there is the coloring material that three classes are main in current dyeing of plastics market, be respectively toner, Masterbatch,
Mill base, specific as follows:
About toner, in plastic, the toner that major part enterprise still uses at present, as white carbon black.
The advantage of toner is that unit price is relatively low, is relatively suitable for the enterprise stricter to cost requirement.Shortcoming is the most very
Obvious: first, in the course of processing, toner dust pollution is very big, and product secondary can be caused dirty
Dye；Secondly as toner is usually chemicals, therefore, the airborne dust of toner is non-to the health hazard of employee
Often, and in the course of processing, the repeatable usability of resin adding toner is poor, and particularly some are important
Color.
Masterbatch is as carrier to wrap up the particle that particle diameter is 2～4mm made by toner using resin.
Masterbatch occupies bigger market in CABLE MATERIALS and each plastic at present.But Masterbatch itself is deposited
In some defects, first, Masterbatch itself is because technique and formula system are limited, and equipment investment is relatively big,
It is generally required to use large-scale screw extruder and other corollary equipments, and, the course of processing is hot-working,
Consume energy higher；Secondly, Masterbatch is owing to using resin as carrier, and the toner content of Masterbatch itself is not
That may do is the highest, the highest, and Masterbatch can be caused to be easily broken, and yield rate is low, so-called on market
Concentration Masterbatch mostly 20～30%, in the case of same tinting strength, tinting power, Masterbatch addition is higher.Its
Equipment required for body processing, energy consumption, manpower conversion cost get off, and integrated cost and unit price are the highest
In toner, produce especially for the less order of small lot or demand and be not easy to implement.
Mill base (can be again color oil) is analogous to Masterbatch in fact, and simply a carrier is hard resin,
One is liquid flux.Mill base dyeing there is problems in that 1, storage performance is poor, and one day without mill base
Will settle and be layered；2, there is pollution environment and the defect of process equipment in mill base.Owing to mill base is difficult to
Cleaning up, produced every time, workman is required for spending a lot of time cleaning equipment, hopper and environment, only
Can be by using organic solvent wiping, volatile matter is discharged in air cause exhaust emission, and because mill base has viscous
Property, have certain residual and waste every time；What 3, the concentration of mill base cannot be done higher (is currently
5%).Owing to industry mill base addition is generally 3 to eight/10000ths, if improving mill base concentration, color
Slurry addition is less, if disperseing the most uniform, the most easily occurs there is the problem that color is inaccurate.
Summary of the invention
The defect existed for prior art, the present invention provides a kind of colouring compositions, described dyeing composition
Thing is solid particle, by weight percentage, including following components: the pigment of 3%～75%, 1%～3%

(4) material of step (3) is delivered to Granulation Equipments and carries out pelletize, be dried except water rewinding,
Obtain described colouring compositions.
The course of processing of above-mentioned colouring compositions is cold working, and equipment investment is little, and can realize automatization
Produce, instead of the bigger large-scale screw extruder of investment used in prior art and other supporting set
Standby, overcome Masterbatch hot-working and the too high defect of manufacturing cost.Pigment in the colouring compositions of preparation
Content reach as high as 75%, close with the content of pigment in toner.
For solid circles granule under the colouring compositions room temperature prepared by above-mentioned steps, when dyeing, will dye
Colour cell compound is mixed into material to be dyed (such as resin), and when entering in extruder, temperature reaches 80 DEG C～160
Starting to melt for liquid when of DEG C (systems for different), this characteristic imparts the dispersion that it is good
Performance, is particularly suitable for the colouring art having precisely requirement to color.
