Abstract

The present invention provides a building ceramic thin-slice brick made of expanded microspheres and a preparation method thereof, comprising a foamed layer and a thin-slab brick, and the raw materials of the foamed layer are as follows: 27-36 parts of ceramic powder, 21 parts of expanded microspheres ‑29 parts, foaming agent 2‑6 parts, auxiliary agent 1‑4 parts. Its outstanding features and excellent effects are: 1. Using well-dispersed expanded microspheres to foam ceramic slurry with certain plasticity, ceramic powder can be evenly covered on the surface of thin slice bricks. 2. The process is environmentally friendly and energy-saving. More importantly, it can effectively control air bubbles, avoid gas escape, and improve foaming efficiency. It can be further promoted in industrial production.

Description

technical field [0001] The invention relates to the field of expanded microsphere materials, in particular to an expanded microsphere foamed building ceramic thin slice brick and a preparation method thereof. Background technique [0002] The development of foamed ceramic materials began in the 1970s and is a porous material with high temperature properties. The pore size ranges from nanometer to micrometer, the porosity is between 20% and 95%, and the use temperature is from room temperature to 1600°C. [0003] Foamed ceramics can generally be divided into two categories, namely open-cell (reticular) ceramic materials and closed-cell ceramic materials, depending on whether the individual cells have solid walls or not. If the solids that form the foam are only contained in the pore edges, it is called an open-cell ceramic material, and the pores are interconnected; if there is a solid wall, the foam is called a closed-cell ceramic material, and the pores are continuous.
