Problems solved by technology

[0003] In recent years, more glass-ceramic decorative panels have appeared in the domestic and foreign markets, among which white-gray, black and dark textured styles account for the majority, and there are fewer styles of glass-ceramics prepared by existing technologies. The problem of single color, with the continuous improvement of people's living standards, there are higher requirements for good building decoration materials, and different colors and styles are needed to meet people's needs. Therefore, glass-ceramics of different colors and styles are developed , is an urgent problem to be solved

Abstract

The invention belongs to the technical field of green and environment-friendly building materials, and in particular relates to a method for preparing sky blue glass-ceramics with star-shaped distribution. The mass percentage of its batch composition is: blast furnace slag 50.1%~52%, silica sand 30.7%~32%, sodium chloride 2.4%~3.1%, titanium dioxide 3.1%~3.8%, sodium fluorosilicate 5.8%~6.8%, Magnesium oxide 4.4%~5.1%, cobalt trioxide 0.1%~0.4%; the uniformly mixed batch is melted at 1550°C for 2.5 hours, and then the glass mixed melt is poured, formed, and annealed to obtain the basic glass; the basic glass Then put it into a crystallization furnace for crystallization treatment to obtain a sky blue glass-ceramic with star-shaped distribution. The invention improves the utilization rate of the blast furnace slag resource, makes the blast furnace slag have higher added value, and realizes the resource regeneration cycle.

Description

technical field [0001] The invention belongs to the technical field of green and environment-friendly building materials, and in particular relates to a method for preparing sky blue glass-ceramic with star-like distribution. Background technique [0002] Blast furnace slag is a solid waste discharged from the metallurgical industry, and its main components are CaO, MgO, Al 2 o 3 , SiO 2 and a small amount of Cr 2 o 3 , Fe 2 o 3 and TiO 2 and other trace components, which constitute CaO-MgO-Al 2 o 3 -SiO 2 An important component of the glass-ceramic system. After the basic glass of this system is processed by the heat treatment process, the diopside crystal phase with excellent performance can be precipitated, which has the advantages of good chemical stability and uniform color, and is corrosion-resistant, wear-resistant, pollution-free, and high in mechanical strength. It is a modern building. One of the ideal decoration materials in the industry. [0003] In r...
