The invention relates to the field of building decorating materials, in particular to a
foam glass ceramic composite
brick and a manufacturing method thereof. The method comprises the following manufacturing steps that 1,
foam glass raw materials are cleaned; 2, the raw materials in the step 1 and a
foaming agent silicon carbide are mixed according to the ratio to obtain a mixture, ball milling is carried out on the mixture, and a
spray drying tower is used for carrying out
powder spraying and pelleting; 3, the mixture prepared in the step 2 is weighed according to the formula, tiled or pressed to be formed, and then placed into a
mullite or
crystallization silicon carbide die, the bottom and the periphery of the die are padded with a layer of high-temperature-resistant paper or coated with a layer of high-temperature-resistant
slurry; 4, a
ceramic thin plate or a tile is placed on the
powder in the step 3 horizontally, and enters a roller
kiln or a
tunnel kiln to be sintered; 5, products are taken out, and
polishing, edging, chamfering and edge
cutting are carried out on the products. In the
foam glass sintering process, the common tile or the
ceramic thin plate is sintered at the same time, the excellent characteristics of the common tile or the ceramic thin plate are retained, and the products are economical and practical.
