Description
Technical field
The present invention relates to plastic colorant technical fields, more particularly to a kind of low-cost environment-friendly EVA smalt and its system
Preparation Method.
Background technique
In order to change certain performances of polymer, such as moulding processability, color, stability, need in forming process
It is middle that some auxiliary agents are added to change certain performances of polymer.Smalt is usually by colorant, carrier, dispersing agent and other auxiliary agents
Composition is blended with a small amount of smalt and uncolored resin when processing, so that it may reach the pigmentary resin or product for designing pigment concentration.Color
Sand is widely used in the resins such as polyvinyl chloride, polyethylene, polypropylene, polystyrene, ABS, nylon, PC, PMMA, PET, production
Motley fiber, clothes, daily plastic, electric wire and cable, household electrical appliance, agricultural film, automobile parts, health-promoting apparatus are gone out
The products such as tool.Have the advantage that pigment is well dispersed using smalt；Reduce coloring workload；Color is accurate；Operation is almost
There is no dust；Reduce equipment cleaning expense.But existing smalt product is bad in thermal stability, and due to flowability of carrier
The problems such as energy is poor, is easy to appear flow liner, uneven color, larger color difference.
Summary of the invention
To overcome technological deficiency of the existing technology, the present invention provides a kind of low-cost environment-friendly EVA smalt and its system
Preparation Method.
The technical solution that the present invention uses is:
Low-cost environment-friendly EVA smalt, is grouped as by the group of following weight fraction: 3050 parts of pigment；EVA micelle 3040
Part；10-15 parts of PE wax；2-4 parts of zinc stearate；5-8 parts of nano zine oxide；10-15 parts of diatomite；4-8 parts of calcium oxide powder.
Preferably, the pigment selects one of red, yellow, blue, green, black, white organic or inorganic color pigments or any ratio
Example mixture.
Preferably, the partial size of the diatomite is 5 μm~20 μm.
Preferably, which is grouped as by the group of following weight fraction: 40 parts of pigment；35 parts of EVA micelle；PE wax 12
Part；4 parts of zinc stearate；5 parts of nano zine oxide；10 parts of diatomite；5 parts of calcium oxide powder.
The present invention further discloses a kind of preparation method of low-cost environment-friendly EVA smalt, has step are as follows:
1) ingredient: weighing each component according to formula, spare；
2) it mixing: launches into mixer mixing and discharges to agglomeration, temperature is controlled at 90 DEG C~110 DEG C；
3) it cuts: the material that step 2) mixing obtains is cut into the fritter of (25~35) cm* (25~35) cm, it is air-cooled to room
Temperature；
4) mill: cutting material after cooling mill on a mill for step 3), and temperature is controlled at 90 DEG C~110 DEG C,
Granny rag, is shaped to the thin cloth-like of (25~35) cm* (25~35) cm, and cooling is spare；
5) be crushed: the thin cloth-like material that step 4) is obtained is crushed to 1cm with crusher.
Beneficial effects of the present invention: smalt of the present invention is mainly by pigment, EVA micelle and nano zine oxide, diatomite and oxygen
Change calcium powder to cooperate, the good anti-ultraviolet property of smalt and anti-aging property can be assigned by nano zine oxide and enhance color
On the one hand on the other hand sand resistance to migration can reduce amount of pigment by diatomite and can mutually grind, be conducive to pigment
Pigment is uniformly dispersed, and smalt thermal expansion coefficient is on the one hand reduced by calcium oxide powder, on the other hand enhancing heat resistance can
It improves the melt index of smalt, have good rheological performance, traditional smalt is overcome flow liner, uneven color, color difference easily occur
The problems such as larger, significantly increases the tinctorial property of plastic products.Smalt color concentration produced by the present invention is high, can replace toner
It uses, and flying dust will not be generated when use, manufacture craft is easier, and cost is relatively low.
