Description
Technical field
The present invention relates to a kind of preparation technology who contains the spherical pearlescent pigment of polyethylene wax, belong to the modified inorganic material technical field.
Background technology
The initial complete processing of pearly-lustre plastics is that pearly pigment is simply mixed with plastics, is reprocessed into goods.This method is contaminated equipment not only, and pearly pigment can't fully disperse, and influences the pearl effect of goods.Especially can't make the more goods of interpolation pearly pigment amount such as pearly-lustre film.In recent years, the importance of pearly-lustre Masterbatch exploitation day by day highlights, and it uses simple; Need not to acquire equipment, pollution-free, only need in plastic pellet, to sneak into a certain amount of pearly-lustre Masterbatch; Through thorough mixing, can carry out injection moulding, blowing or extrusion moulding and process the pearly-lustre plastics.And the goods pearl effect is good, and pearly pigment is uniformly dispersed in goods.
Polyethylene wax is a low molecular weight polyethylene, is auxiliary agent commonly used in the plastic working industry.When plastic extruding forming, use polyethylene wax, can improve the flowability of material, improve output, and can allow higher packing density.The application of polyethylene wax in Masterbatch processing is very general.The purpose of adding polyethylene wax not only is to improve the processibility of Masterbatch system, the more important thing is to promote dispersing of pigments in the Masterbatch.The quality of Masterbatch depends primarily on wherein colo(u)rant dispersion degree.Colo(u)rant dispersion is good, and the tinting strength of Masterbatch is high, and the tinctorial quality of goods is all right, and painted cost is also low.Polyethylene wax can improve the dispersing of pigments level to a certain extent, is dispersion agent commonly used during Masterbatch is produced.Because the difference of method of manufacture, polyethylene wax are divided into two kinds on aggretion type and cracking type.Because of the difference of molecular structure, polyethylene wax exists the difference of method of manufacture, density, MWD and molecular structure, so the application performance in Masterbatch also has nothing in common with each other.
Summary of the invention
It is reasonable that technical problem to be solved by this invention provides a kind of technological design, makes at follow-up Masterbatch to add man-hour, plays the reduction system viscosity, improves the preparation technology of the spherical pearlescent pigment that contains polyethylene wax of pigment compatibility and wettability.
It is this preparation technology who contains the spherical pearlescent pigment of polyethylene wax that the present invention solves the problems of the technologies described above the technical scheme that is adopted, and its preparation process is:
A, pearly pigment and polyethylene wax are dropped into the high mixer high speed with weight ratio 1 ~ 2.33 mix, stirring velocity is 50r/min, stirs 30min, obtains the system compound, and this process does not heat;
B, with steam the system compound is heated, be warming up to 90 ℃, the control steam valve makes temperature be controlled at 90 ~ 110 ℃, insulation 45 ~ 60min, material in the middle of obtaining;
C, material in the middle of in the high mixer is carried out naturally cooling, when temperature was reduced to below 70 ℃, blowing obtained containing the spherical pearlescent pigment of polyethylene wax, and 90% particle diameter of spherical pearlescent pigment is the 6-18 order.
As preferably, pearly pigment of the present invention is Fu Wode silvery white model FWD120A, FWD110K or FWD D10X.
As preferably; Comprise MOX composition and the organic coloring pigment of forming pearly pigment in the component of pearly pigment of the present invention; In metal oxides such as titanium dioxide, red oxide of iron, Z 250, cobalt sesquioxide, zinc oxide, the chromium sesquioxide one or more, one or more in organic coloring pigment such as C.I. pigment Yellow 12, C.I. Pigment red 22, C.I. pigment Violet 23, C.I. pigment blue 1 or the C.I. pigment Green 7.
As preferably, the weight ratio of pearly pigment of the present invention and polyethylene wax is 1.8.
As preferably, polyethylene wax of the present invention is Honeywell AC-6A polymkeric substance or AC-8A polymkeric substance.
The present invention has the following advantages and characteristics with existing compared with techniques: the present invention is the surface treatment component with the polyethylene wax, and the pearly pigment that makes interpolation to organic sex reversal, becomes lipophilic-hydrophobic property by inorganic nature.Make at follow-up Masterbatch to add man-hour, the consistency and the wettability of pigment significantly improve.Both guarantee the abundant dispersion of pearly pigment, avoided the loss of pearl effect again.And pearly pigment after treatment heap volume reduces greatly, can improve addition.In addition, polyethylene wax can play the effect that reduces system viscosity, improves flowability, improves Masterbatch production efficiency, increases output.
