Problems solved by technology

Its advantages lie in short technological process, simple operation, and many kinds of colors. Its disadvantage is low tinting strength. At the same time, the volatile point of zinc oxide is low, and the burning loss is large. The volatile zinc oxide is poisonous and harmful. The melting point of borax is extremely low. Very easy to agglomerate, which is not good for discharging and grinding

Embodiment 1

[0035] According to the chemical formula BaCr 2 (P 2 o 7 ) 2 The stoichiometric ratio of each element in , respectively weighed BaCO 3 : 1.98 g, Cr 2 o 3 : 1.52 g, NH 4 h 2 PO 4 : 4.74 g. After grinding and mixing uniformly in an agate mortar, choose the air atmosphere for the first calcination, the temperature is 300°C, and the calcination time is 5 hours, then cool to room temperature, and take out the sample. After the first calcination of the raw materials, the mixture was ground and mixed evenly, and still calcined in the air atmosphere, the calcination temperature was 1350° C., the calcination time was 7 hours, and naturally cooled to room temperature. After the sample was ground to uniformity in the same way, it was calcined at 1200° C. for 8 hours in an air-atmosphere muffle furnace to obtain the target product. Looking at a sample of the material clearly shows that the sample appears bright green to the human eye.

[0036] See attached figure 1 , which is ...

Embodiment 2

[0042] According to the chemical formula BaCr 2 (P 2 o 7 ) 2 The stoichiometric ratio of each element in the formula, respectively weighed BaO: 1.54 grams, Cr(NO 3 ) 3 : 4.76 g, NH 4 h 2 PO 4 : 4.74 g. After grinding and mixing uniformly in an agate mortar, choose the air atmosphere for the first calcination, the temperature is 350°C, and the calcination time is 4 hours, then cool to room temperature, and take out the sample. After the first calcined raw material, the mixture was ground and mixed uniformly, and the uniformly ground sample was calcined in an air atmosphere muffle furnace at 1300°C for 6 hours. Next, the sample cooled to room temperature was ground and calcined again in the same way. This time, the calcining temperature was 1250° C. and the calcining time was 7 hours to obtain the target product. Main structural properties, infrared spectrum and absorption spectrum are similar to Example 1.

Embodiment 3

[0044] According to the chemical formula BaCr 2 (P 2 o 7 ) 2 The stoichiometric ratio of each element in the 3 ) 2 : 2.62 g, Cr 2 o 3 : 1.52 g, P 2 o 5 : 2.84 g. After grinding and mixing uniformly in an agate mortar, select the air atmosphere for the first calcination, the temperature is 340°C, and the calcination time is 5 hours, then cool to room temperature, and take out the sample. After the first calcined raw materials, the mixture is ground and mixed evenly, and calcined under the air atmosphere, the calcining temperature is 1350° C., and the calcining time is 6 hours. Finally, grind the sample cooled to room temperature evenly and put it into a muffle furnace for calcination. The calcination temperature is 1230° C. and the calcination time is 5 hours to obtain the target product. Main structural properties, infrared spectrum and absorption spectrum are similar to Example 1.

Abstract

The invention discloses a phosphate inorganic material, a method for producing the same and an application. The prepared inorganic material is alkaline earth transition metal phosphate which takes Ba<2+> and Cr<3+> to react together, has a chemical formula of BaCr2(P2O7)2, is prepared through adopting a high-temperature solid state method or a chemical solution method, belongs to phosphate type mineral inorganic pigment, and has the advantages of weather resistance, temperature resistance, environmental friendliness and energy saving. The phosphate inorganic material emits green light under the sun, has the functions of coloring, covering, protecting and the like, can be applied to products of printing ink, coating, plastics, polymer and the like, and is particularly suitable for coating buildings with high performance requirements. The adopted producing method is simple and has good reproducibility, is stable in quality of the produced product, and is easy for operation and industrial production.

Description

technical field [0001] The present invention relates to the preparation method and the application of the phosphate green pigment of a kind of inorganic matrix, particularly relate to a kind of Ba 2+ 、Cr 3+ The invention discloses a preparation method and application of a co-reacted alkaline earth metal transition metal phosphate green pigment, which can be applied in the coating fields of architecture, ink, plastics, etc., and belongs to the technical field of inorganic pigment materials. Background technique [0002] After nearly 300 years of industrial development, pigments have become a mature industrial production and product segmentation industry. According to their chemical composition, pigments can be roughly divided into organic pigments and inorganic pigments. The color of organic pigments is brighter and more vivid, the color spectrum is complete, the tinting strength is stronger, the density is lower, and the oil absorption is higher. However, organic pigments ...
