Microcrystal glass ceramic composite plate and one-time rapid sintering method thereof

Abstract

The invention relates to the technical field of building materials, and discloses a microcrystal glass ceramic composite plate which is prepared by sintering microcrystal glass particles, a crystal leading agent and a ceramic raw blank, wherein the crystal leading agent comprises the following ingredients in percentage by mass: 50-70% of SiO2, 3-8% of Al2O3, 5-15% of BaO, 5-20% of B2O3 and 2-12% of KNaO. The invention further discloses a one-time rapid sintering method of the microcrystal glass ceramic composite plate. According to the method, the crystal leading agent is introduced into the microcrystal glass ceramic composite plate, the crystal patterns are enlarged by utilizing the property that the crystal leading agent and the microcrystal glass particle material are different in surface tension and viscosity and are subjected to interinfiltration without chemical reaction; in addition, a crystal leading agent layer with various patterns is printed on the ceramic raw blank through a silk screen process, the crystal patterns of the sintered microcrystal glass ceramic composite plate grow regularly, and the patterns are controllable; and moreover the limit of the conventional process is broken through, the microcrystal glass ceramic composite plate can be rapidly sintered at one time, and the sintering period is reduced to be 60 minutes.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a glass-ceramic composite board and a rapid firing method thereof. Background technique [0002] Glass-ceramic composite board is a high-end decorative building material product. It is crystal clear, elegant, naturally grown and varied stone-like texture, brightly colored layers, uncanny appearance decoration effect, and free from pollution, It is easy to clean, has excellent physical and chemical properties, and has stronger weather resistance and weather resistance than stone, so it is favored by high-end building materials markets at home and abroad. [0003] At present, most of the glass-ceramic composite panels produced in the market use wollastonite as the crystalline phase, and its crystallization feature is that it grows toward the interior of the particles along the particle edges of the glass-ceramic particles, and the appearance shows a collection of particl...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the glass-ceramic composite panels produced in the market use wollastonite as the crystalline phase, and its crystallization feature is that it grows toward the interior of the particles along the particle edges of the glass-ceramic particles, and the appearance shows a collection of particles, so Although this kind of glass-ceramic is also crystal clear, rich and luxurious, but the style of particle collection is a bit monotonous.

[0004] However, although the glass-ceramic composite board with zinc silicate and pyroxene as the crystal phase can break through the original particle boundary and recombine into natural growth textures with different shapes such as spherical shape and rhyolite shape, the pattern is still only 0.6-0.8 cm is large, and the crystal flowers grow irregularly into clusters, and the appearance looks messy

This makes the existing glass-ceramic composite panels unable to achieve the effect of mass decoration

[0005] In addition, most of the traditional glass-ceramic composite panels adopt the secondary firing process, which has a long firing cycle and high energy consumption, which is not conducive to energy saving and emission reduction.
