Embodiment Construction

[0016] The present invention is described in further detail below:

[0017] The present invention is realized in this way: first prepare the inorganic titanium yellow pigment carrier, then ultrafine nano-grinding, coat the organic yellow pigment on the inorganic titanium yellow pigment carrier, form the inorganic titanium yellow pigment as the core, and the ultrafine organic yellow pigment as the package The organic and inorganic composite pigment of matter, the specific implementation method:

[0018] Step 1. Prepare inorganic titanium yellow pigment carrier slurry, mix and grind titanium dioxide and nickel oxide metal oxide, solid-phase synthesize inorganic titanium yellow pigment carrier with positive charge on the surface, add 50-70% deionized water by weight percentage to prepare Inorganic titanium yellow pigment carrier slurry, then fine grinding D90 is less than 3 microns (D90 means that more than 90% of the fine grindings are less than 3 microns). The pH value of the ...

Abstract

The invention relates to the technical field of chemical pigment fabrication and discloses a high-temperature-resistant environment-friendly composite pigment and a production method thereof. Inorganic titanium yellow pigment carriers are enveloped with organic yellow pigments to form the composite pigment. The preparation method comprises processing titanium dioxide and nickel oxide into mixed-phase inorganic titanium yellow pigment carriers to be mixed with organic yellow pigments with negative charges, and performing enveloping treatment through positive and negative charge particle attraction action to achieve composition of organic and inorganic pigments. By nanometer fine processing, surface charges are increased, the envelop is dense, the structure force is large, the composition process is environmentally friendly, the composite pigment is non-toxic, the composite titanium yellow carriers can protect the sensitive organic pigments from ultraviolet attack like ultraviolet absorbers, and accordingly, the weather resistance and the light resistance of the pigment are improved greatly, and the pigment has the advantages of being environmentally friendly, weather resistant, light resistant, heat resistant, anti-ageing, bright in organic pigment color and high in tinting strength.

Description

technical field [0001] The invention relates to the technical field of chemical pigment manufacturing, in particular to a high-temperature-resistant and environment-friendly composite pigment compounded with organic and inorganic pigments and a preparation method thereof. Background technique [0002] At present, more and more attention is paid to environmental protection at home and abroad, and the use of pigments containing heavy metals and toxic carcinogens has been restricted worldwide. Developed countries and regions such as my country, Europe and the United States have formulated a series of limit value standards, especially for substances that come into close contact with people. According to the European and American REACH regulations, the use of harmful substances has been completely banned, which affects the direct export of my country's related pigments to the EU. The main varieties of existing yellow pigments are cadmium yellow, chrome yellow and organic yellow....
