Problems solved by technology

But because its own appearance is white, it is easy to cause white pollution, causing a certain degree of pollution to the atmosphere, and also damages the human retina to a certain extent.
[0004] The patent application with the application number 201410405705.1 discloses a preparation method of an inorganic-organic composite yellow pigment. Although the pigment has the advantages of good thermal stability and light stability, and the composite yellow pigment has a similar color with the inorganic yellow pigment lead chrome yellow. Compared with , it shows more excellent coloring performance, such as higher coloring power, brighter color, more pure yellow, etc., but the operation steps in the preparation process are cumbersome, it is difficult to guarantee the quality in large-scale production, and the cost is high; and The synthesis temperature is high, which is not conducive to industrial production

preparation example 3

[0032] Firstly, 30g of glycine was dissolved in 120mL of distilled water, and then 29.1g of Ni(NO 3 ) 2 ·6H 2 O and 34g of butyl titanate were dissolved and stirred on a magnetic stirrer with a set temperature of 60°C until the solution was completely dissolved to obtain a clear liquid (about 20 minutes). Then heated to 110 ° C for 100 minutes, during which the liquid viscous expansion, followed by release of gas, rapid self-propagating combustion reaction, forming a loose powder. The obtained powder was calcined at 900°C for 4 hours to obtain the yellow nano-pigment NiTiO 3 .

[0033] The NiTiO obtained in Preparation Example 2 3 It is used in the preparation of the following composite superfine yellow ceramic pigments.

Embodiment 1

[0035] A preparation method of composite superfine yellow ceramic pigment, comprising the steps of:

[0036] 1) Add 2g of nickel titanate to 100mL of water, stir well to obtain solution A;

[0037] 2) Mix 0.852g butyl titanate (0.2g titanium dioxide after conversion) with 3 volume times absolute ethanol to obtain solution B;

[0038] 3) Add solution B dropwise to solution A under stirring conditions, stir at room temperature at a speed of 90 rpm for 6 hours, and then stand and age for 48 hours to obtain an opaque gel;

[0039]4) The opaque gel obtained in step 3) was first dried at 80°C for 4 hours, then dried at 90°C for 2 hours, then ground to obtain a loose precursor powder, and finally transferred to a muffle furnace and roasted at 400°C for 5 hours to obtain a composite type ( NiTiO 3 / TiO 2 ) Ultrafine yellow ceramic pigment.

Embodiment 2

[0041] A preparation method of composite superfine yellow ceramic pigment, comprising the steps of:

[0042] 1) Add 2g of nickel titanate to 100mL of water, stir well to obtain solution A;

[0043] 2) Mix 3.409g butyl titanate (0.8g titanium dioxide after conversion) with 2 volume times absolute ethanol to obtain solution B;

[0044] 3) Add solution B dropwise to solution A under stirring conditions, stir at room temperature for 5 hours at a speed of 90 rpm, and then leave to age for 24 hours to obtain an opaque gel;

[0045] 4) The opaque gel obtained in step 3) was first dried at 80°C for 4 hours, then dried at 90°C for 2 hours, then ground to obtain a loose precursor powder, and finally transferred to a muffle furnace and roasted at 400°C for 5 hours to obtain a composite type ( NiTiO 3 / TiO 2 ) Ultrafine yellow ceramic pigment.

Abstract

The invention belongs to the technical field of ceramic pigments, and concretely relates to a compound type ultrafine yellow ceramic pigment and a preparation method thereof. The preparation method concretely comprises 1) dissolving nickel titanate in water to obtain a solution A; 2) uniformly mixing butyl titanate and anhydrous ethanol being 2-3 times by volume of butyl titanate, so as to obtain a solution B; 3) adding the solution B into the solution A under the stirring condition, stirring at room temperature for 5 h or more, and then standing for ageing for 24-48 h, so as to obtain an opaque gel; and 4) drying and grinding the opaque gel obtained in the step 3) to obtain a loosen precursor powder, then transferring into a muffle furnace, and roasting at 400-500 DEG C for 4-6 h, so as to obtain the yellow ceramic pigment. The compound type ultrafine yellow ceramic pigment obtained through the preparation method combines excellent performances of NiTiO3 and TiO2, and possesses advantages of bright color, no color variation at high temperature, and the like.

Description

technical field [0001] The invention belongs to the technical field of ceramic pigments, and in particular relates to a composite superfine yellow ceramic pigment and a preparation method thereof. Background technique [0002] The meaning of yellow in physics should be the color of monochromatic light with a wavelength of 597-577nm. Yellow ceramic pigments are indispensable for ceramic decorative arts, whether they are used for color decoration of ceramic products or as colorants for ceramic glazes or color embryos. decoration material. Most of the traditional yellow pigments contain toxic heavy metals such as lead and chromium, which have a serious impact on the environment and individuals, and the traditional single-performance pigments can no longer meet the needs of all walks of life. At the same time, we know that when the size of the material is reduced to the nanometer level, it has incomparable superior performance of conventional materials. Therefore, it is impera...
