Abstract

The invention discloses a novel microcrystallite glass-ceramic composite brick and a production method thereof. The production method comprises the following steps of: (1) preparing low-viscosity glass clinker and high-viscosity glass clinker; (2) preparing microcrystallite glass-ceramic composite brick blank powder for later use by the conventional method; (3) preparing a microcrystallite glass-ceramic composite brick substrate by using the obtained microcrystallite glass-ceramic composite brick blank powder for later use; (4) preparing the microcrystallite glass-ceramic composite brick; and (5) performing aftertreatment. The prepared microcrystallite glass-ceramic composite brick is low in firing temperature, and short in firing period; energy consumption can be reduced greatly, emission is reduced, and preparation cost is saved; the surface of the prepared microcrystallite glass-ceramic composite brick has a small amount of blowholes; and the prepared microcrystallite glass-ceramic composite brick is high in soil resistance, and abrasive resistance, and can fully meet the requirement of using performance.

Description

technical field [0001] The invention relates to the technical field of building ceramics, in particular to a novel glass-ceramic composite brick and a production method thereof. Background technique [0002] Glass-ceramics has excellent properties such as compact structure, wear resistance, corrosion resistance, high mechanical strength, and strong weathering resistance, and can be used as high-grade building decoration materials. However, the whole body of glass-ceramics has high energy consumption, high pollution and high cost during manufacture; while glass-ceramics is used as the surface finish layer, or a mixture of glass-ceramics and ceramics is used as the surface finish layer, and then ordinary ceramics As the bottom support layer, made of glass-ceramic composite bricks is conducive to greatly reducing energy consumption, reducing emissions, saving manufacturing costs, and is easy for large-scale industrial production. [0003] The basic production process of glass-...
