Description
Technical field
The present invention relates to a kind of pearlescent pigments, specifically, being related to a kind of special no current mark pearlescent pigment of plastic cement and its system
Preparation Method.
Background technology
The plastic products of coloured appearance just become new fashion.In order to obtain coloured appearance, generally require on plastic basis material
It paints, it is beautiful, beautiful to achieve the effect that.But spraying process has complicated flow, production cost height, to environment dirt
The a series of problems such as big, the spraying cost height of dye.
Therefore, it is that product brings beautiful, fashion appearance that more and more manufacturers, which are sought for alternative spraying technology,
Propose the concept for exempting from spraying.Various plastics can be directly molded into using the high molecular material for exempting from spraying with effect pigment cooperation to match
Part directly obtains the plastic products of coloured appearance, removes lacquer spraying technique from, reduces the injury to environment, and substantially reduce manufacture
Cost.Plastics exempt from spraying process and have considered MAT'L recycling and environmental issue, meet the trend and trend of green manufacturing
(Xu Bengang, Wang Bin, Liu Yuebin, research [J] the engineering plastics for waiting moulding process to improve surface special-effect material visual defects
Material application, 2011,39 (4):50-52.).
And the pigment with particular color effect such as nacreous mica pigment come prepare exempt from painted plastic will become prevalence.Because
Pearl powder has colourful color, is easy to a variety of colors effect of arranging in pairs or groups out, disclosure satisfy that the demand of different clients.But piece
Shape effect pigment will appear the problems such as current mark, weld mark when being molded applied to plastic cement industry, influence the beauty of product.It is right
It can be improved (Wang Gui dragon rapid thermal cycles injection molding key by the technique that rapid thermal cycles are molded in Shooting Technique
Technical research and application [D] Shandong University, in 2011), or need to be redesigned (Yang Guisheng, Gao Jun, Lee to mold
A kind of eliminations of art exempt to spray injection mold [P] .CN201720299753.6 of thermoplastic current mark, and 2017), but not
Powder is modified under the premise of changing Shooting Technique, is more economical effective mode.For flake pigment applied to
Shooting Technique generates the main reason for current mark etc., it is believed that be powder grain size it is larger, cause larger shearing resistance (the good of Wu Rong
The genetic analysis of injection-molded item surface flow marks and research [D] South China Science ＆ Engineering University, in March, 2012).
For can be applied to the sheet effect pigment of plastic-injection industry, focus primarily upon using fluorine resin substance
Rear cladding either mixing but it is this after coat or be mixed the non-uniform situation of processing (Dong Qiannian, Xu Junjun, Xu
Pupil pupil, etc..A kind of strip aluminium pigment [P] .CN201610594818.X of the smooth few current mark in surface, 2016).

Penetrate the metal or nonmetal oxide or hydroxide of rate, the metal or nonmetal oxide or hydroxide of the low-refraction
It is preferred that or mixtures thereof silica, alundum (Al2O3).
Antioxidant etc. is typically contained in plastics, usually there is certain active aldehydes matter, this substance is in high temperature
Plastics can be made to turn yellow with the material effect of pearlescent pigment color effects layer when processing, beauty be influenced, especially for white pearlescent face
Material.Therefore the pigment that accumulation color is white colour system is needed to carry out anti-yellowing processing.And it is that dark color such as contains oxidation for accumulation color
The pigment of iron, it is insensitive to xanthochromia because powder intrinsic colour is deeper, therefore the layer generally can be omitted, but can also wrap
Containing the layer.
Anti-yellowing layer is can to shelter color effects layer photolytic activity or thermoactive substance, is typically chosen property stabilization, nothing
Photoactive substance.In the present invention, it is preferred to anti-yellowing layer be silica, alundum (Al2O3), zirconium oxide, cerium oxide, aluminum phosphate,

In the present invention, anti-yellowing layer can carry out coating anti-yellowing layer again after the cladding calcining of color clad, can be calcined again, also
It can not calcine, or coat anti-yellowing layer again after having coated color effects layer, it later can be according to requiring to carry out calcining or not
It is calcined.Anti-yellowing pearly-lustre is also known as herein for the substance containing the above clad.
In the injection moulding process of plastics, mold and the injection molding of satisfied injection molding effect can be obtained having already passed through technique adjustment
Under technique, just it is easier to the problem of current mark occur when pigment is added, this phenomenon after the sheet effect pigment especially added
Just become more serious.In the present invention, under the premise of not changing mold, in order to obtain satisfied injection molding effect, to above
Common pearlescent pigment carries out organic coating processing, and organic painting processing refers to that can reduce table in pearlescent pigment powder cladding
The fluorine-containing coat of face tension, the fluorine-containing coat are collectively constituted by fluorine-containing segment and polyoxyethylene segment.
The organic coating mixed after general is difficult uniformly to be disperseed with powder, therefore the present invention passes through in-situ polymerization
The powder of acquisition its organic layer cladding can be more uniform.
The special pearlescent pigment of plastic cement of the present invention is applied in common pearlescent pigment powder surface in-situ preparation fluoropolymer
Layer, because containing polyoxyethylene segment and fluorine-containing segment, surface has smaller friction coefficient, can reduce pigment powder the coating
Shearing of the body in plastic processing processing procedure promotes the arrangement of powder, and then reduces current mark and weld mark.And for individually making
With the powder of fluorine-containing coat, dredged because it has the characteristics that water oil is double, it is it is difficult to evenly dispersed to carry out dispersion and kneading in the plastic
, it will not improve current mark instead but this defect can be aggravated, and the special pearlescent pigment of plastic cement of the present invention includes fluorine coating
Include also simultaneously polyoxyethylene groups segment, the part-structure and the compatibility with plastics can be improved, promotes to disperse, with fluorine-containing
The defects of disconnected part collective effect, improvement even is eliminated current mark and weld mark.
The preparation method is that first carrying out the cladding of the polymer containing polyoxyethylene segment, carry out again later fluorine-containing
The cladding of segment substance also considers the double thin properties of water oil of fluorine-containing material.If fluorine-containing segment substance is first coated, then into
It will cause difficulties in dispersion when the cladding of the row substance of segment containing polyoxyethylene groups, coat difficult problem, and it is full cannot to obtain effect
The product of meaning.
The present invention in above-mentioned common pearlescent pigment in situ Polymerization by obtaining fluoropolymer coating so that obtained
The special no current mark pearlescent pigment of plastic cement is applied to plastic cement industry, can obtain no trace, the product without fusing trace, reach
The effect of best anti-current mark, and because surface fluoropolymer-containing processing so that powder is mainly distributed in the plastic
In the surface layer of plastics and arrangement regulation, there is apparent decorative effect.
