Technology of dying granite stone blue or green

Abstract

The invention provides a novel technology of dying granite stone blue or green for the architectural decoration industry. The technology comprises the following steps: respectively preparing A steeping fluid and B steeping fluid from potassium ferrocyanide the common name of which is yellow prussiate of potash and ferric salt, and sequentially impregnating the granite stone in the A steeping fluid and the B steeping fluid in a normal pressure manner or a pressurized manner, respectively drying the granite stone at the temperature of 100-150 DEG C after impregnating, polishing, draining water, smearing 201 methyl silicone oil, and then dying off-white granite stone and heather gray granite stone blue or green. The technology is characterized by simple production equipment, simple production operation and low cost, and the dyed blue granite stone or green granite stone has brilliant color on appearance and inside, has good weathering resistance and still remains the physical and chemical properties of the original granite stone at the same time.

Description

Technical field [0001] The invention relates to a technique for coloring granite stones blue (or green), and relates to a coloring solution and a coloring processing method for coloring granite stones blue (or green). Background technique [0002] As we all know, among the natural granites, off-white and hemp gray are the most common and the most common. Although there are other granites in red, yellow, green, black, purple and other colors, they are increasingly scarce with continuous mining; As far as blue-colored granite is concerned, it is rare in nature, and there are very few. At present, there are only reports of "Norwegian blue" granite, and there are almost no blue granite stones for sale in the domestic market. [0003] In order to meet the increasing demand for colored granite stones of different hues in the architectural decoration market, people use artificial coloring methods to achieve the purpose of increasing the variety of colored granite. At present, the...

Problems solved by technology

[0004] In order to overcome the disadvantages that the blue variety cannot be obtained by inorganic salt coloring method of granite stone and the blue variety obtained by dyeing with organic dyes has poor heat resistance and weather resistance and is easy to lose color, the invention provides a new two-component coloring solution (A, B liquid), so that after the granite is impregnated and dried, it can not only be colored with bright blue or green colors, but also the colored granite stone has good water resistance, heat resistance, and weather resistance. It still maintains the original physical and chemical properties of granite
