Description
Technical field
The present invention relates to inorganic pigment technical field more particularly to a kind of coated molybdenum bismuth vanadate yellow pigment and its preparations
Method.
Background technique
Cadmium yellow (CdS) and chrome yellow (PbCrO4、BaCrO4), have many advantages, such as bright-colored, strong covering power, cheap, is
Instantly the Inorganic yellow pigment generally used on the market, and applicating history is long, use scope is wide.However, due to contained
Cadmium, lead and chromium (VI) poisoning metal element can seriously endanger human health and pollute environment, therefore, develop novel environment-friendly type yellow
Color pigment is not only imperative to replace, more significant.
Molybdenum pucherite (general formula BiVO4·nBi2MoO6, 0.2≤n≤2) and it is a kind of Advanced Inorganic that novel environment friendly is nontoxic
Yellow uitramarine, tone can be regulated and controled by the size of n value, and when n value is gradually increased, tone is yellow by red phase Huang Xiang Lvxiang
Transformation, as n=0.75, the pigment yellow PY184 that the BASF AG as to have appeared on the market registers on pigment index, it is by four directions
The BiVO of crystal form4With the Bi of rhombic form2MoO6The Yellow organic dye of the bright green of composition, strong covering power.
Currently, the manufacturing method of molybdenum bismuth vanadate yellow pigment has calcination and precipitating-calcination method.Calcination is
By corresponding oxide or the salt that corresponding oxide can be generated through thermal decomposition by composition ingredient, after solid-phase ball milling mixes, in height
The lower calcining of temperature.Precipitating-calcination method is first to dissolve corresponding water-soluble each salt ingredient, under the conditions ofs corresponding temperature and pH etc.
Them are made to generate oxides or hydroxide gel precipitating, then in about 600 DEG C of temperature after the precipitating of generation is washed, dried
Lower calcining, ultimately forms the BiVO mutually adjoined4And Bi2MoO6Two-phase crystallization.Above two method finally must wet-milling, suction filtration
To reach corresponding granularity, not only technique is cumbersome, but also gained granules of pigments granularity is still larger, it is difficult to meet higher using need
It asks.
In addition, the above-mentioned pigment of the prior art is intolerant to strong acid, and when being calcined to 600 DEG C or more, pigment can make because of sintering
It darkens, loses glassy yellow, thus cannot be used under strong acid environment, also may not apply to the more demanding neck of temperature tolerance
Domain, such as engineering plastics, high-temperature coatings, glass ink, ceramic paint.It therefore, is the service performance for improving pigment, to molybdenum vanadic acid
Bismuth yellow uitramarine carries out the hot spot that surface modification treatment has become research and development, and the method mainly used at present is in the pigment
Surface deposit colorless inorganic matter protective film, such as zirconium silicate, phosphate and various oxides, but pigment granules and nothing in the prior art
Machine protective film be only mutual mixing and absorption together, protective film is not fine and close enough, therefore the effect is unsatisfactory.
