Abstract
The present invention provides a kind of color sand and preparation method thereof, which is made of the raw material including following parts by weight：15 45 parts of PE resins, 50 80 parts of toner pigment, 15 parts of processing aid, 0.5 1 parts of antioxidant.Color sand of the present invention is processed by the addition of auxiliary agent and antioxidant, and using plastic grinder, is made color is husky have good dispersiveness, coloring dynamics, improve clear efficiency, can be improved environment.
Description
Technical field
The invention belongs to plastic applications, more particularly, to a kind of color sand and preparation method thereof.
Background technology
Toner assigns plastics with color, adds the aesthetic feeling of plastic products, attract consumer's as coloring plastic raw material
Desire to purchase (such as daily necessities, toy), improves the weather resistance of product, and different color applications is in different fields, such as：With
In indicative purpose (such as traffic lights, electric wire), for military affairs (such as green black colour), for agricultural, (such as mulch, tomato use red
Color mulch, ginseng use yellow mulch etc.).
Although toner is easy to use, because its particle diameter is small, density is low, and color is miscellaneous, causes it easily to fly upward, and pollutes ring
Border, equipment, are also easy to cause in process of production the cross contamination of product, there is certain injury to human body, do not meet present
Environmental requirement；Since toner is easily adhered chamber wall (polybag, mixing equipment etc.), toner is caused to have certain loss, without
Ji；Weigh toner and take longer, and toner adhesion screw rod, the equipment such as lower hopper, cause clear difficult, inefficiency；Toner is equal
It is tiny dust, is not easy to measure, it is difficult to realizes automation.
Have at present and matched colors using Masterbatch, because Masterbatch particle is big, specific surface area is small, in toner content below 0.5%
When, colour fluctuation is severe in production process, or even occurs variegated, can reduce product quality and production efficiency；Masterbatch into
It is husky that this can also be higher than color.
The content of the invention
In view of this, the present invention is directed to propose a kind of color sand and preparation method thereof, has good dispersiveness, tinting strength, tinting power
Degree, improve clear efficiency, improve environment.
To reach above-mentioned purpose, the technical proposal of the invention is realized in this way：
A kind of color is husky, which is made of the raw material including following parts by weight：
Preferably, the color sand is made of the raw material including following parts by weight：
Preferably, the color sand is made of the raw material including following parts by weight：
Further, the PE resins are the mixture of one or both of LDPE or LLDPE.
Further, the toner raw material is for one kind in the organic pigment or inorganic pigment of coloring plastic.
Further, the processing aid is one or more mixed in high molecular polythene wax, EBS or stearate
Compound.
Further, the antioxidant is one or more in Hinered phenols antioxidant or phosphite ester kind antioxidant
Mixture.
The preparation method of the color sand, includes the following steps：
(1) PE resins, toner pigment, processing aid, antioxidant are added into high-speed mixer or mixer are uniformly mixed,
Obtain mixed material；
(2) the feeder feeding extruder or mixer by the mixed material obtained in step (1) by delicate metering
In, it is kneaded, extruded, being cooled down, pelletizing；
(3) particle obtained in step (2) is put in plastic grinder be milled up to the color sand.
Further, the temperature control of the milling step in the step (3) is at -70--10 DEG C, the particle diameter for the step that is milled
Control is in 100um-500um.Selected flour mill is the special milling equipment of plastics, uses the temperature of liquid nitrogen control milling.
Further, the extruder selection single screw extrusion machine or double screw extruder in the step (2), described squeezes
The melting temperature for going out step is 150-220 DEG C.
The application of the color sand, application of the color sand in color masterbatch, dyeing of plastics is prepared.
Relative to the prior art, color sand of the present invention and preparation method thereof has the advantage that：
Color sand of the present invention is processed by the addition of auxiliary agent and antioxidant, and using plastic grinder, is made
Color is husky to be had good dispersiveness, coloring dynamics, improves clear efficiency, can improve environment.
Embodiment
In addition to being defined, technical term used has universal with those skilled in the art of the invention in following embodiments
The identical meanings of understanding.Test reagent used, is routine biochemistry reagent unless otherwise specified in following embodiments；It is described
Experimental method, is conventional method unless otherwise specified.
With reference to embodiment, the present invention will be described in detail.
Embodiment 1
A kind of color is husky, which is made of the raw material including following parts by weight：122 50 parts of 45 parts of LDPE, Red are high
3 parts of molecular polyethylene wax, 0.5 part of antioxidant 1010,0.5 part of irgasfos 168.
The preparation method of the color sand, includes the following steps：
(1) PE resins, toner pigment, processing aid, antioxidant are added into high-speed mixer or mixer are uniformly mixed,
Obtain mixed material；
(2) the feeder feeding extruder or mixer by the mixed material obtained in step (1) by delicate metering
In, the melting temperature of extruder is 150-220 DEG C, is kneaded, extruded, cooled down, pelletizing；
(3) particle obtained in step (2) is put in plastic grinder be milled up to the color sand.
Color prepared by embodiment 1 is husky compared with the coloring dynamics and dispersiveness of original-pack toner, formula and result
Data are shown in Table 1, table 2, table 3.
1 color of table is husky (to be tried out in the PP of 20% filling automotive material, following material with the color of original-pack toner verification formula
Quality adds quality for 25KG PP materials).
