A kind of foam glass ceramic composite brick and preparation method thereof

Abstract

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.

Description

technical field

[0001] The invention relates to the field of building decoration materials, in particular to a foam glass-ceramic composite brick and a preparation method thereof. Background technique

[0002] Foam glass is a kind of porous inorganic non-metallic material which is made of waste flat glass and bottle glass and foamed at high temperature. Anti-magnetic wave, anti-static, high mechanical strength, good adhesion with various types of mud. It is a heat insulation, sound insulation and waterproof material for building exterior walls and roofs with stable performance. According to reports, foam glass can also be used in heat preservation projects of flue, kiln and cold storage, heat insulation, waterproof and fire prevention projects of various gas, liquid and oil pipelines, subways, libraries, office buildings, opera houses, theaters, etc. Various places that require sound insulation and heat insulation equipment, isolation and sound insulation projects for infr...
