Embodiment 1

[0028] The sintered brick produced by using ceramic brick waste slag includes the following raw materials in parts by weight: 40 parts of quartz sand, 15 parts of potassium sodium sand, 50 parts of ceramic edging powder, and 25 parts of waste brick slag.

[0029] 1) Weigh each raw material according to the proportion, add water and carry out wet ball milling until the fineness of the powder is above 200 mesh;

[0030] 2) Making the slurry in step 1) into powder granules with a water content of 6-8wt%, and stale for 24 hours;

[0031] 3) Compress the material obtained in step 2), then dry it through a drying kiln, and finally fire it at 1050-1100°C, keep it warm for 30 minutes, and finally cool down;

[0032] Through the above operations, fired bricks were obtained.

Abstract

The invention discloses a sintered brick produced by using ceramic brick waste slag and a preparation process thereof. The sintered brick comprises the following raw materials in parts by weight: 20-40 parts of quartz sand, 10-15 parts of potassium sodium sand, and ceramic edging powder 35‑50 parts, 15‑25 parts of waste brick slag. In a preferred scheme, it may also include 5-10 parts of raw fly ash, 10-20 parts of clay, 3-8 parts of wollastonite, 5-8 parts of diopside and 1-3 parts of bentonite. It uses ceramic brick waste slag instead of ordinary clay to produce sintered bricks, and the firing temperature is low, which solves the problem that ceramic factory waste cannot be used, reduces production costs, saves resources, and protects the environment.

Description

technical field [0001] The invention belongs to the field of ceramic production, and in particular relates to a sintered brick produced by using waste slag of ceramic bricks and a preparation process thereof. Background technique [0002] The waste slag produced by the production of ceramic tiles is increasing day by day, which not only causes great pressure on the environment, but also affects the sustainable development of ceramic enterprises. Therefore, the utilization of waste slag from ceramic tiles is very important. Ceramic tile waste is currently the most difficult to use and the least used waste in ceramic enterprises. Contents of the invention [0003] The object of the present invention is to provide a kind of sintered brick produced by using waste slag of ceramic bricks and its preparation process. The waste slag is used instead of clay to prepare sintered bricks, which solves the problem that waste from ceramic factories cannot be used, reduces production cost...
