Embodiment 1

[0016] The component content of the ceramic green body is (percentage by weight): 1% of coal gangue, 44% of kaolin, 29% of quartz, 13% of feldspar and 13% of dolomite. The above-mentioned raw materials are weighed according to the proportion, mixed evenly, finely crushed by ball milling, and a certain amount of water is kept. Put the processed blank into a plate mold and press it with a press to form a blank, and then apply 3mm thick particle size by dry method twice. A glass-ceramic composite layer with different particle size distributions ranging from 0.1 mm to 5.5 mm, wherein the different particle size distribution means that the particle size closer to the green body is smaller, and the particle size closer to the outer surface is larger. Put the processed green body into the roller kiln for rapid crystallization and firing, polish the fired plate, and cut it into finished products according to the required size.

Embodiment 2

[0018] The component content of the ceramic green body is (percentage by weight): 13% of coal gangue, 32% of kaolin, 25% of quartz, 15% of feldspar and 15% of dolomite. The above raw materials are weighed according to the proportion, mixed evenly, finely crushed by ball milling, and a certain amount of water is kept. Put the processed billet into the plate mold and press it with a press to form a billet. Apply a layer of thickness of 0.3mm by wet or dry method The white make-up soil, the chemical composition of make-up soil is (percentage by weight): SiO 2 .: 60%, AL 2 o 3 : 16%, CaO: 4%, MgO: 5%, KNaO: 15%, and then use 4 dry methods to apply a 6mm thick glass-ceramic composite layer with a particle size of 0.1mm-5.5mm and different particle sizes. The different particle gradation means that the closer to the green body, the smaller the particle size, and the closer to the outer surface, the larger the particle size. Put the processed green body into the roller kiln for ra...

Embodiment 3

[0020] The component content of the ceramic green body is (percentage by weight): 22% of coal gangue, 24% of kaolin, 26% of quartz, 13% of feldspar, and 15% of dolomite. The above raw materials are weighed according to the proportion, mixed evenly, finely crushed by ball milling, and a certain amount of water is kept. Put the processed billet into the plate mold and press it with a press to form a billet. Apply a layer of thickness of 0.5mm by wet or dry method The white make-up soil, the chemical composition of make-up soil is (percentage by weight): SiO 2 .: 64%, AL 2 o 3 : 16%, CaO: 4%, MgO: 5%, KNaO: 11%, and then use 4 dry methods to apply a 10mm thick glass-ceramic composite layer with a particle size of 0.1mm-5.5mm and different particle sizes. The different particle gradation means that the closer to the green body, the smaller the particle size, and the closer to the outer surface, the larger the particle size.

Abstract

A composite microcrystal glass-ceramic plate contains SiO2 (55-70 wt.%), Al2O3 (16-32), CaO (0.5-5), MgO (0.5-5) and KN2O (1-8), and is prepared from coal gangue (0.45-22.5 wt.%), Kaolin (22.5-49), quartz (20-30), feldspar (10-15) and dolomite (5-8) through calcining.

Description

technical field [0001] The invention relates to a glass-ceramic composite plate and a method for manufacturing the composite plate. Specifically, the present invention relates to a glass-ceramic composite board made of industrial waste—coal gangue and a method for manufacturing the composite board. Background technique [0002] Glass-ceramic plate is a beautiful and practical high-grade decorative material, but its popularization and application is greatly limited due to its high cost. Ceramic tiles have become a widely used traditional decorative material due to their low cost, high output and many varieties. Although glass-ceramic-ceramic composite bricks have appeared in the prior art, their production costs are still on the high side. At present, industrial waste is either landfilled or piled up in the wilderness, causing serious pollution to the natural environment. Contents of the invention [0003] The purpose of the present invention is to use coal gangue as the...
