Abstract
The invention discloses a high temperature wear resistant sericite pearlescent pigment which is characterized by comprising a substrate, the substrate is coated with a layer of a titanium oxide film, and the titanium dioxide film is coated with a layer of a colorant to form a metal oxide composite coating. The colorant is ferric oxide. The substrate is a white sericite pigment. The beneficial effects of the high temperature wear resistant sericite pearlescent pigment are that: the luminance and chrominance of the high temperature wear resistant sericite pearlescent pigment are increased dramatically, the process is more easy to operate and more perfect, the reaction is more stable, the stability of product quality is better, by coating with the inorganic metal oxide-ferric oxide, the high temperature wear resistant sericite pearlescent pigment is higher in stability, and may not fade at higher temperature.
Description
Technical field
The present invention relates to a kind of pigment, be specifically related to a kind of high-temperature wearable sericite pearly pigment.
Background technology
The performance of pearly pigment excellence becomes the new approaches in current color field, has very high 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.
But the research of the high-grade pearly pigment of China at present still can not meet the demand in market, great majority need to be to the pearly pigment of external import, particularly high-temperature wearable, 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, a kind of high-temperature wearable sericite 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 high-temperature wearable sericite pearly pigment, it comprises a base material, and base material is coated with layer of titanium dioxide film, and titanium deoxid 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 white sericite pigment.
Sericite 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: 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.

Embodiment
embodiment:the present embodiment provides a kind of high-temperature wearable sericite pearly pigment, and it comprises a base material 1, and base material is coated with layer of titanium dioxide film 2, and titanium deoxid 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 sericite.The steps include: (1) by levigate sericite to 5-20 μ m; (2) activation; (3) activation sericite is made into the suspension of 3-20%, regulates pH value to 1.5-2.5 with acidic solution, in 60-80 DEG C of water-bath, add the titanium tetrachloride solution of 10-15% in the mode dripping, drip basic solution simultaneously and keep the stable of pH value; In the time there is obviously flash of light in solution, stop dripping liquid, by solution filter, and water will wash extremely neutrality, be dried into powder; (4) powder is incubated to 0.5-2 hour at 850-900 DEG C, cooling rear grinding is broken up, and obtains white sericite base material.
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 cladding titanium dioxide and ferric oxide successively, react complete, filter, by deionized water wash, oven dry, calcining and other processes, just obtain high-temperature wearable sericite pearly pigment.
High-temperature wearable sericite pearly pigment of the present invention, 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.If it is upper to use it for material object, under the irradiation of light, can reach beyond thought effect, solve the deficiency of the high-grade pearly pigment of China.
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.
