Abstract
The invention provides a blue effect pigment which comprises a compound layer coated on the surface of a base material and a carbon dioxide layer coated outside the compound layer. The pigment is cobalt blue in appearance and has good dispersity and double color effect. As the carbon dioxide layer and silicon dioxide balls with a certain grain size are coated on the outermost layer of the pigment, adhesion of the pigment during high temperature calcining can be prevented to ensure that particles exist in a dispersed state to the maximum extent, thereby facilitating dispersion of the pigment and exerting the color effect of the pigment as much as possible when the pigment is applied. Meanwhile, the pigment applied has a three-dimensional light scattering effect, so that the reflected light is more flexible. The pigment has high-temperature-resistance and weather-resistance, and can be widely applied to ceramic, plastic and coatings.
Description
Technical field
The present invention relates to chemical field, particularly a kind of blue effect pigment and preparation method thereof, purposes.
Background technology
Effect pigment is had to good optical effect for decorating, the one, give goods pearlescent gloss, this phenomenon is to be produced by the multi-level arrangement of the translucent particle of pearly pigment stratiform, be the different interfaces of light between pigment and base material, and all frictional belt of effect pigment itself are to light multiple reflections, refraction and form the result of the interference of light.The 2nd, make the intangible surprised effect of vision.Therefore, this optical effect that has the pigment of special effect to be usually used to beautify article, and be widely used in makeup, plastic cement, coating, leather and pottery in.
Traditional double-colored pigment is the surface colour at pearly pigment, normally pigment dyestuff or inorganic oxide.Pigment dyestuff can not be high temperature resistant, and inorganic oxide does not have blueness.Patent US3951679 has described a kind of pigment, and it is take pearly pigment as basis, in this surface of pigments Prussian blue coating layer, this pigment shortcoming is Prussian bluely at 200-300 ℃ of temperature, will decompose.
The pearly pigment that patent US4968351 describes, it is that adsorption coloring agent is painted, precipitation is coated on the absorption with strengthening tinting material on tinting material.The shortcoming of this pigment is in the time contacting with organic solvent, and organic colorant will separate from pearly pigment, this by all or part of lose color.
Indigo plant-the phthalocyanine being formed by matrix and surface layer that patent US5169442 describes, matrix comprises the mica coated with burning, and surface layer is by the compositions of mixtures of magnesium oxide, calcium oxide, cobalt oxide and titanium dioxide, the main look of this pigment is not pure blue.
The existing multi-coated interference pigment take blueness as mass-tone, its constructional feature is " colourless, the transparent metal oxide layer/Leyden blue of colourless, transparent metal oxide layer/grazing shot rate of substrate/high refractive index, containing the skin of cobalt glass or cobalt oxide ", or " substrate/Leyden blue, containing colourless, the transparent metal oxide layer of colourless, the transparent metal oxide layer/substrate/high refractive index of cobalt glass or cobalt oxide layer/grazing shot rate ".
To so far, all these blue or equal non-refractories of blue double-colored pigment (more than 1000 ℃), and can not be used in pyroceramic goods.
Summary of the invention
The object of the invention is to provide a kind of existing good dispersiveness and two-color effect, and its outward appearance look is gorgeous cobalt blue, has corresponding interference pigment, has again high-temperature stability and weathering resistance, can be widely used in pottery, plastics and coating.
The blue effect pigment of one of realizing the object of the invention, is included in substrate surface coated composites layer, and the silicon dioxide layer of described composite layer outer cladding.
Wherein said composite layer is the composite layer of aluminum oxide and cobalt oxide.
On wherein said silicon dioxide layer, then deposit layer of silicon dioxide ball.
Wherein said silica spheres particle diameter is 30-100nm.
The mol ratio of wherein said aluminum oxide and cobalt oxide is 1:6-6:1.
The weight percent of the each component of wherein said blue effect pigment is:
Aluminum oxide and cobalt oxide mixture 5-50%
Silica 1-20%
Silica spheres 0-5%
Base material surplus.
Described blue effect pigment, wherein said base material is pearly pigment.
Wherein said pearly pigment is the pearly pigment using mica, synthetic mica, tabular alumina or sheet silicon oxide as substrate.
Described blue effect pigment, wherein said base material is that sheet synthetic mica, natural mica, tabular alumina and flaky silicon dioxide are that the titanium of substrate, surperficial cladding titanium dioxide is interference pigment.
A method of preparing described blue effect pigment, comprises the following steps:
(1) base material is mixed with appropriate pure water, form still liquid and heat up;
(2) be under agitation metered into metal salt solution, make substrate surface coated composites layer;
(3) add sodium silicate solution;
(4) solution above-mentioned steps being formed filters, washs, dries, calcines.
Wherein further comprise and adjust the temperature of described still liquid and the step of pH value.
Wherein said metal salt solution is the mixed solution of aluminum salt solution and cobalt salt solution.
The temperature of wherein said still liquid is 60-90 ℃, and described pH value is 7-9.

Beneficial effect of the present invention:
Pigment of the present invention has good dispersiveness and two-color effect, and its outward appearance look is gorgeous cobalt blue, and has corresponding interference color.There is high-temperature stability and weathering resistance, can be widely used in pottery, plastics and coating.
The present invention is due to the silica spheres of be coated with silicon oxide at the outermost layer of pigment layer and certain particle diameter, they can prevent pigment " bonding die " in the time of high-temperature calcination on the one hand, be that particle adheres to each other each other, guarantee that particle exists with dispersion state to greatest extent, be conducive to be easy to disperse and large as far as possible performance color effect in the time of application; Owing to there being the scattering of light effect of silicon ball, make pigment there is cubic light dispersion effect in the time of application on the other hand, i.e. diffuse effect, the light of reflection is softer.
Because pigment flakes surface is coated with silicon oxide ball, there is anti-settling effect again, make to have to resist at the pasty material such as glaze, coating of preparation to fall effect, be conducive to pigment and be evenly distributed in material.
In a preferred embodiment of the invention, while adopting pearly pigment prepared by resistant to elevated temperatures substrate as substrate, its resistance to elevated temperatures can reach more than 1100 ℃, and outward appearance blueness is more gorgeous and be specially adapted in ceramic glaze.When interference color are while being blue, blue interference color with the blue superimposed more gorgeous effect pigment that obtains of outward appearance.
