Abstract
The invention discloses a special luminous pearlescent pigment for ceramic firing. The pigment is characterized in that the pigment comprises a sheet substrate, the substrate is coated with a high-refractive-index coat, and the high-refractive-index coat is coated with a layer of a coloring agent to form a metal oxide composite coat. The coloring agent is ferric oxide. The sheet substrate is synthetic mica composed of a long-afterglow luminous material and a base flux. The special luminous pearlescent pigment is optically variable, and has the advantages of good brightness and color saturation, high brightness, intelligible pattern, color variety, excellent glaze quality, strong mechanical performances, and high chemical stability; and the coating of the inorganic metal oxide-ferric oxide makes the pigment have a high stability and not fade under high temperature firing conditions.
Description
Technical field
The present invention relates to a kind of ceramic sintering pigment, be specifically related to the special luminous pearly pigment of a kind of ceramic sintering.
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, be desirable ceramic sintering pigment.It has the flash effect of metallic pigment, can produce the soft color and luster of natural peral.The performance of pearly pigment excellence becomes the new approaches in current color field, has higher commodity value.Pearly pigment is widely used in the industries such as building coating, rubber, pottery.
But the research of the pearly pigment that China's ceramic sintering is used at present still can not meet the demand in market, high-end product great majority need to be to external import, and price is very expensive.Particularly its preparation method is loaded down with trivial details, step is many, reaction process is consuming time long, wayward and realize industrialization; 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, provide a kind of ceramic sintering special luminous pearly pigment, by the coated ferric oxide of pigment outermost layer, 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:
The luminous pearly pigment that ceramic sintering is special, it comprises a flat substrates, and base material is coated with one deck high refractive index coating, and high refractive index coating is also coated with one deck tinting material outward, forms metal oxide superpacket coating.
Described tinting material is ferric oxide or other metal oxides.
Described flat substrates is the synthetic mica of long after glow luminous material and basic flux composition.
Synthetic mica pigment can combine with transparent pigment dyestuff, or directly carry out painted with these pigment, the effect producing is very charming, pigment dyestuff is restricted in the application in some fields, its use temperature can not exceed 120 ℃, but 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: the ceramic product burning out has the effect of changeable colors along with angle, and product brightness and fullness of shade all relatively good, luminosity is high, clear patterns, color is various, glaze quality is good, mechanical property is strong, chemical stability is high.By coated inorganic metal oxide-ferric oxide, its stability is higher, under high-temperature firing, can not produce and fade.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present invention.
In figure: 1. synthetic mica 2. high refractive index coating 3. tinting materials of long after glow luminous material and basic flux composition
Embodiment
embodiment:the present embodiment provides a kind of ceramic sintering special luminous pearly pigment, and it comprises a flat substrates 1, and base material is coated with one deck high refractive index coating 2, and high refractive index coating is also coated with one deck tinting material 3 outward, forms metal oxide superpacket coating.
Described tinting material is ferric oxide, or other metal oxides.
The synthetic mica of described flat substrates long after glow luminous material and basic flux composition.
In specific implementation process, in temperature 70 C-80 ℃, keep the stirring of base material suspension, the pH value of reaction is stable, at the surface of base material cladding titanium dioxide and ferric oxide successively, react complete, filter, by deionized water wash, oven dry, calcining and other processes, just obtain the special luminous pearly pigment of ceramic sintering.
The luminous pearly pigment that ceramic sintering of the present invention is special, the effect with changeable colors along with angle is used up from the alternately irradiation of three specific directions, can reflect multiple distinct colors; And product brightness and fullness of shade all improve a lot, and brightness and fullness of shade all relatively good.
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 equivalent structure 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)
