Description

technical field [0001] The invention relates to a granite colorant composed of organic dyes and auxiliary agents and its coloring technology. Granite colored with organic dyes is bright in color and has excellent light and wash resistance. The granite slabs colored by this technology have even color inside and outside, low price, and are ideal slabs for modern decoration. Background technique [0002] Decorative stone is an important part of building decoration materials. It is a high-end building product that integrates material function, color and shape, and integrates science, technology, culture and art. The development level of decorative stone plays an important role in the grade of high-rise buildings, beautifying the urban environment and improving living conditions; in recent years, with the vigorous development of urban construction and large-scale open development, various luxury buildings and high-rise buildings have sprung up like mushrooms Rising from the gro...

Problems solved by technology

However, most of the existing granite products in our country are still low-grade varieties. The supply of ordinary gray-white granite slabs produced by a large number of township enterprises exceeds demand, and the price is several times higher than ordinary gray-white varieties. For example: "China Red", "Sichuan Red", "Norwegian Blue" and "South African Black" are very few. Therefore, at present, my country still needs to import hundreds of thousands of tons of "Indian Red" and other varieties every year, and the price is very expensive; In order to meet the needs of architectural decoration, it is imperative to study the processing and coloring technology of low-grade stone materials, which is of great practical significance.

[0003] For this reason, scholars from various countries have been committed to the research of this technology. U.S. Patent U.S. 4430091; 3494715; Ordinary dyes used in dyeing cloth, although the appearance color is good, but the washing and light fastness are poor
