Abstract
The invention discloses a white titania pearlescent pigment. The white titania pearlescent pigment is characterized in that a base material lithopone is matched with an aluminum hydroxide gel and titania, a gel film is formed on the surface of lithopone under the action of the aluminum hydroxide gel, the lithopone gel film is chemically coated by titania, and the aluminum hydroxide gel film is coated with a layer of a coloring agent to form a metal oxide composite coat. The coloring agent is ferric oxide. The white titania pearlescent pigment is optically variable, has a good brightness and color saturation, has a far lower price than a titania pigment, has a better whiteness than titania, has near main performances with titania, and has the advantages of short process flow, simple technological conditions, only adoption of a routine chemical industry apparatus, and convenience for the industrialized production. An inorganic metal oxide-ferric oxide is coated, so the white titania pearlescent pigment has a high stability and does not fade at a high temperature.
Description
Technical field
The present invention relates to a kind of pigment, be specifically related to a kind of white titanium white pearly pigment.
Background technology
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.Particularly titanium white pearly pigment, can obtain the effect of high gloss colour flicker, also can obtain the effect that gloss is softer, and market using value is huge.
But the research of the high-grade pearly pigment of China at present still can not meet the demand, particularly titanium white pearly pigment in market, price is very expensive.The popularization that limited its wider use.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, a kind of white titanium white pearly pigment is provided, 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:
A kind of white titanium white pearly pigment, taking zinc sulfide white as base-material, be furnished with aluminum hydroxide gel and titanium white, under aluminum hydroxide gel effect, make zinc sulfide white surface form glued membrane, lithopone film adhesive is carried out to chemical coating processing with titanium white, aluminum hydroxide gel film is also coated with one deck tinting material outward, forms metal oxide superpacket coating
Described tinting material is ferric oxide.
Described base material is zinc sulfide white.
Titanium white pearly pigment can combine with transparent pigment dyestuff, or directly carry out painted with these pigment, the effect producing is very charming, its color not only can not weaken, and can strengthen on the contrary, and pigment dyestuff is restricted in the application in some fields, its use temperature can not exceed 120 DEG C, 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: there is the effect of changeable colors along with angle, and product brightness and fullness of shade all relatively good, if use it in kindly upper, under the irradiation of light, can reach the effect of multi-light reflection, solved the part deficiency of the high-grade pearly pigment of China.In addition, compared with traditional pearly pigment, its brightness and colourity all significantly promote, make technique be easier to operation, more perfect and reaction more stable, the good stability of quality product.By coated inorganic metal oxide-ferric oxide, its stability is higher, at higher temperature, can not produce and fade.
Brief description of the drawings
Fig. 1 is cross-sectional view of the present invention.
In figure: 1. base-material 2. aluminum hydroxide gel film 3. tinting materials
Embodiment
embodiment:the present embodiment provides a kind of white titanium white pearly pigment, and it comprises a base-material 1, and base material is coated with one deck aluminum hydroxide gel film 2, and aluminum hydroxide gel film 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.
Described base-material is zinc sulfide white.
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, at the surface of base material cladded aluminium hydroxide gel and ferric oxide successively, react complete, filter, by deionized water wash, oven dry, calcining and other processes, just obtain white titanium white pearly pigment.
Titanium white pearly pigment of the present invention, there is the effect of changeable colors along with angle, and product brightness and fullness of shade are all relatively good, price is far below titanium dioxide pigment, and whiteness is better than titanium white, and salient features approaches titanium white, its technical process is brief, processing condition are simple, only adopt conventional chemical industry equipment, are convenient to suitability for industrialized production.By coated inorganic metal oxide-ferric oxide, its stability is higher, at higher temperature, can not produce and fade.。
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)
