Abstract

The invention provides a deep color microcrystalline glass frit and a method for preparing deep color microcrystalline glass ceramic composite boards. A certain amount of coloring oxides are introduced into a basic microcrystalline frit to prepare a frit raw material; and the formula of the frit raw material comprises the following components: 60 to 62 percent of SiO2, 1 to 2 percent of B2O3, 17 to 20 percent of CaO, 5 to 7 percent of Al2O3, 3 to 5 percent of Na2O, 4 to 6 percent of ZnO and a proper amount of coloring agent, wherein the percentage content sum of the components is 100 percent. The method comprises the following steps of: melting the frit raw material at a high temperature to produce glass frits of deep color series of bright black, dark green, deep coffee and the like, processing the glass frits into certain granularity, spreading the processed glass frits on ceramic biscuit fired substrates, and performing high-temperature sintering to obtain bright black, dark green and deep coffee microcrystalline glass composite boards. The microcrystalline glass composite boards have noble and elegant color and luster and natural and attractive crystal flower effect, and are favored by the market.

Description

technical field [0001] The invention relates to the technical field of ceramic building materials, in particular to a dark glass-ceramic frit and a method for preparing bright black, dark green and dark brown glass-ceramic ceramic composite plates produced by using the dark glass-ceramic frit. Background technique [0002] The application of glass-ceramics in ceramic decoration originated in the late 1990s. At the beginning, glass-ceramic frits of a certain size were spread on refractory boards, fired in a shuttle kiln for 30-40 hours, and then polished. Due to the large amount of 3-wollastonite crystals precipitated during the firing process, the polished surface has a large number of 3-wollastonite crystal flowers, so its wear resistance is better than that of ordinary crystal mirror floor tiles. It is very popular in the market, but its disadvantages are small output, long production cycle and high cost. [0003] So at the beginning of the 20th century, it was developed ...
