Pink pigment with high temperature resistance and preparation method thereof

Abstract

The invention relates to the technical field of pigments. The invention aims to provide a pink pigment with high temperature resistance. The pink pigment comprises the following raw materials in parts by weight: 15-20 parts of basic red; 2-5 parts of glacial acetic acid; 3-6 parts of disodium hydrogen phosphate; 8-12 parts of sodium tungstate; 18-20 parts of sodium molybdate; 2-4 parts of a temperature-resistant modifier; the temperature-resistant modifier is formed by mixing nanoscale titanium dioxide and nanoscale kaolin according to the weight part ratio of 2: 1. The pigment is subjected to inorganic hybrid modification by adding the high-temperature-resistant auxiliary agent, and the nanoscale titanium dioxide is used as a pigment particle core, so that the thermal stability of the pigment is greatly improved, and the nanoscale titanium dioxide is small in particle size, uniform in dispersion and more convenient for forming a core, so a connection structure between pigment molecules is more stable, and the pigment is more stable. The produced pigment not only has the characteristics of high temperature resistance, light resistance and the like of an inorganic pigment, but also has the characteristics of bright color and strong coloring degree of an organic pigment.

Description

technical field [0001] The invention relates to the technical field of pigments, in particular to a pink original with high temperature resistance and a preparation method thereof. Background technique [0002] Pigment, as a widely used dyeing material, has been widely used in various industries such as paint, printing and dyeing, plastic products, papermaking, rubber products and ceramics. In recent years, with the transformation of industrial production from high speed to high quality, the market has higher and higher requirements for various properties of pigments. Pigment purple, as a basic color type in pigments, is a basis for compounding other color type pastes. At the same time, it is the same as pigment red, and it is also the two most commonly used color type raw materials in inks. [0003] In recent years, after years of research and development, our company has developed a series of pigment violet with basic red as the basic colorant, and after many iterations o...

Problems solved by technology

At the same time, in some special use occasions, due to the consideration of other factors such as environmental protection and pollution, it is impossible to simply replace the organic pigments with stepless pigments to solve the coloring problem of the product. Therefore, if some relatively simple Improving the high temperature resistance of pigment red by means of methods will undoubtedly greatly improve its application scope and market prospects

[0005] At the same time, in terms of production and preparation process, due to the need to dissolve basic red in hot water, when using traditional dissolving tanks for dissolving operation, not only the dissolving time is long, but also the incomplete dissolving problem will affect Subsequent production and processing
