Abstract
A kind of bluish-green series pearlescent pigment, it includes: 1) base material；2) SnO on base material it is deposited on2+TiO2Clad；With 3) it is deposited on SnO2+TiO2Chromium zinc cobalt class blue pigment clad on clad；Wherein chromium zinc cobalt class blue pigment layer is made up of chromium oxide, zinc oxide, cobalt oxide and aluminium oxide or is mainly made up of chromium oxide, zinc oxide, cobalt oxide and aluminium oxide.Also provide for preparation method and its purposes of bluish-green series pearlescent pigment.
Description
Technical field
The present invention relates to bluish-green series pearlescent effect pigment and preparation method thereof, belong to inorganic non-metallic effect pigment field.
Background technology
With the transparent sheet-like of low-refraction for base material, the pearlescent pigment being coated with the metal-oxide (or alternately cladding high index of refraction and low-refraction oxide) of one or more layers high index of refraction and obtain, have bright and colourful form and aspect, bright gloss, the effect of changeable colors along with angle and be used widely.But because it is light interfere pigment, coloring is poor, in order to strengthen its coloring, it is common practice to physical deposition or mixed transparent organic pigment.Organic pigment is bright in colour, chromatograph is complete, but organic pigment non-refractory and organic solvent, also not weathering, corrosion resistant, therefore carrying out painted with inorganic pigment to pearlescent pigment is reasonable selection.First-selected strong coloring force, transparent, nontoxic inorganic pigment.
In pigment, blue pigment is the pigment that application is extremely wide, and principal item includes phthalocyanine blue, barba hispanica, fresh ultramarine, cobalt blue, especially excellent with cobalt blue performance.Cobalt blue class pigment is a kind of inorganic, metal oxide mixed phase pigment, has spinel structure, and Typical molecular formula is A (II) B2(III)O4, it is believed that it is that cobalt instead of spinelle MgAl2O4Magnesium formed cobalt blue.By adding Zn, Cr, and adjust its ratio, a series of chromium zinc cobalt blue pigment can be obtained, such as extra large dark blue (Cr, Zn, Co), the pigment 28 (cobalt blue) in " Colour Index ", pigment 36 (chromium cobalt blue)；The blue 229# (containing Co, Al) of imperial family of ShepherdColor company, flag indigo plant 214# (containing Co, Al), arctic indigo plant 3# (containing Co, Al), kingfisher indigo plant 211# (Co, Cr, Al), topaz indigo plant 9# (Co, Cr, Al).This kind of pigment is referred to as chromium zinc cobalt, has the light resistance of excellence, weatherability, chemical resistance, high temperature resistant, has more painted, nontoxic, transparent bright, the good coloring agent of pearlescent pigment just.
Traditional this kind of pigment is the high temperature solid state reaction synthesis adopting high-temperature calcination, obvious this method is not suitable for the painted of pearlescent pigment, the mechanical mixture of two kinds of pigment can not better be processed, the gloss making pearlescent pigment on the contrary reduces, therefore must at pearlescent pigment (lamellar) uniformly one layer of cobalt blue class pigment of coating, its color firmness, brightness, tinting strength, tinting power can reach optimum efficiency.
Bluish-green class pearlescent effect pigment of series obtained with chromium zinc cobalt class blue pigment colored nacreous pigment and preparation method thereof there is not yet bibliographical information.
Chinese patent CN201410040504 describes a kind of blue effect pigment, and it is based on interference colours pearlescent pigment, is coated with cobalt aluminate clad and silicon dioxide layer and obtains a kind of blue effect pigment, be exactly substantially cobalt blue (CoAl in this surface of pigments2O4) painted pearlescent pigment.
Chinese patent CN201410023987 describes a kind of single coating chromium cobalt green cladding nacreous mica composite pigment, is namely coated with nano chrome cobalt green CoCr at mica surface2O4Particle.Employing coprecipitation is coated with, with CoCr2O4Individually the refractive index of cladding is little and opacity, will not produce obvious pearl effect.
