Method for producing microcrystalline glass-ceramics composite board with novel microcrystalline phase

Abstract

The invention discloses a method for producing a microcrystalline glass-ceramics composite board with novel microcrystalline phase, which is characterized in that the composite board takes diopside-containing pyroxene as microcrystalline phase and the production method thereof comprises the steps as follows: firstly, microcrystalline glass granules are prepared; according to the weight percentage, the microcrystalline glass consist of 50-65% of SiO2, 5-25% of Al2O3, 5-20% OF CaO, 2-10% of MgO, 1-8% of K2O+NaO, 0-1% of Li2O, 0-8% of BaO, 0-8% of B2O3 and the balance of nucleating agent, clarifier and corant with the content ranging from 0 to 20%; secondly, a ceramic palette board is prepared; according to the weight percentage, the ceramic palette board comprises 66-75% of SiO2, 13-23% of Al2O3, 0.3-3% of CaO+MgO, 3-8% of K2O+Na2O and the balance of 0-2% of auxiliary raw material; finally, the raw materials are distributed, sintered and post-processed, thus gaining the finished product of the microcrystalline glass-ceramics composite board. The method has the advantages of low production cost, high product quality, good appearance effect, and the like.

Description

technical field

[0001] The invention relates to the technical field of building materials, in particular to a method for producing a glass-ceramic-ceramic composite plate with a new type of microcrystalline phase. Background technique

[0002] Glass-ceramic-ceramic composite panel is a high-end decorative building material product that combines "21st century high-end decorative material" - glass-ceramic with ceramic tiles that can achieve large-scale mechanized production and low cost. At present, due to the high technological content of this kind of composite material and the difficulty of production technology, there are few manufacturers that can achieve normal mass production, and the existing products are only microcrystalline phases of wollastonite (CaSiO 3 ) glass-ceramic-ceramic composite plate, the crystallization characteristic of this microcrystalline phase-wollastonite is that it grows toward the inside of the particle along the edge of the particle of the glass-...
