Abstract
A disclosed pearlescent pigment with iridescent effect is characterized in that the pearlescent pigment comprises a sheet-shaped base material; the external of the base material is coated with a titanium dioxide coating in which calcium and magnesium are added, and the titanium dioxide coating is mainly composed of anatase titanium dioxide, so that the porosity of the coating surface is reduced (or the smoothness is improved), and the pearl luster of the pearlescent pigment and the high iridescent effect generated based on interference color are improved; also the titanium dioxide coating is coated with a layer of a coloring agent for forming a metal oxide composite coating, and the coloring agent is ferric oxide; and the base material is the sheet-shaped base material and is one of mica, synthetic mica and glass flakes. The beneficial effects of the pearlescent pigment comprise that iridescent pearlescent effect is generated under the irradiation of light, the metal oxide composite coating enables the pigment to have relatively good stability and low production cost; and also the pearlescent pigment has excellent coloring power and relatively good product brightness and color saturation, and does not fade at a relatively high temperature.
Description
Technical field
The present invention relates to a kind of pigment, be specifically related to a kind of pearly pigment that can not produce the iris effect of fading at higher temperature.
Background technology
Pearly pigment is nontoxic, tasteless, acid and alkali-resistance, nonflammable, non-explosive, non-conductive, do not move, easily disperse, there is higher thermotolerance and weathering resistance, meet strict environmental requirement completely.Can produce the soft color and luster of natural peral, under the condition that is subject to light, just can show sparkle effect.
The performance of pearly pigment excellence becomes the new approaches in current color field, has higher commodity value.Pearly pigment is widely used in every field, the coating, powder coating, building coating, pearl ink, pearly-lustre leather, pearly-lustre plastics, the pearly-lustre makeup that can be used for automobile, motorcycle, bike, also can be used for the industries such as papermaking, printing and dyeing, stamp, rubber, pottery.
Common pearly pigment color and luster a little less than, and color is single.But the research of the high-grade pearly pigment of China still can not meet the demand in market at present, and great majority need to be to external import, and price is very expensive.Interference effect between each layer of pigment finished product a little less than, exist brightness, saturation ratio is lower, under hot conditions, easily fade etc. not enough.
Summary of the invention
The object of the invention is for above-mentioned deficiency, a kind of pearly pigment of iris effect is provided, by taking flat substrates as mica, one of them is base material for synthetic mica or glass flake, and be coated with coating of titanium dioxide at pigment base material, in coating of titanium dioxide, add calcium and magnesium, outermost layer is coated ferric oxide, it is reached and at higher temperature, can not produce the effect of fading.
For achieving the above object, the technical scheme adopting is in the present invention:
A kind of pearly pigment of iris effect, it comprises thinks mica, one of them is base material for synthetic mica or glass flake, base material is coated with layer of titanium dioxide coating, in coating of titanium dioxide, add calcium and magnesium, coating of titanium dioxide is also coated with one deck tinting material outward, forms metal oxide superpacket coating.
Described tinting material is ferric oxide.
Described base material is mica, synthetic mica or glass flake one of them.
Coat coating of titanium dioxide on its surface and be coated with coating of titanium dioxide at pigment base material, in coating of titanium dioxide, adding calcium and magnesium.Can combine with transparent pigment dyestuff, the effect producing is very charming.By the metal oxide-ferric oxide of coated inorganic, its stability is higher, at higher temperature, can not produce and fade.
The invention has the beneficial effects as follows: under the irradiation of light, can produce iris pearl effect, the compound integument of burning can allow pigment stability better, and production cost is low; Have good tinting strength, product brightness and fullness of shade are all relatively good simultaneously, and can not produce and fade at higher temperature.
Brief description of the drawings
Fig. 1 is cross-sectional view of the present invention.
In figure: 1. base material 2. coating of titanium dioxide 3. tinting materials
Embodiment
embodiment:the present embodiment provides a kind of pearly pigment of iris effect, it comprises a base material 1, and base material is coated with layer of titanium dioxide coating 2, adds calcium and magnesium in coating of titanium dioxide, coating of titanium dioxide is also coated with one deck tinting material 3 outward, forms metal oxide superpacket coating.
Described tinting material is ferric oxide.
Described base material mica, synthetic mica or glass flake one of them.
In specific implementation process, in temperature 70 C-80 DEG C, keep the stirring of base material suspension, the pH value of reaction is stable, in the surperficial cladding titanium dioxide coating of base material, add calcium and magnesium, ferric oxide, reacts complete thoroughly, filters, by deionized water wash, oven dry, calcining and other processes, just obtain the pearly pigment of iris effect.
The pearly pigment of iris effect of the present invention can produce iris pearl effect under the irradiation of light, and the compound integument of burning can allow pigment stability better, and production cost is low; Have good tinting strength, product brightness and fullness of shade are all relatively good simultaneously, and can not produce and fade at higher temperature.
But the foregoing is only better possible embodiments of the present invention, not in order to limit to the scope of the claims of the present invention, therefore the equivalence that all utilizations specification sheets of the present invention and accompanying drawing content are done changes, be all included in protection scope of the present invention.
Claims (3)
