Abstract

The invention discloses a preparation method of a water-permeable ceramic brick. The preparation method comprises the following steps: preparing of raw materials, dosing, mixing, forming, drying and sintering, wherein the raw materials are composed of the following components in parts by weight: 86-92 parts of ceramic tile waste ceramic particles, 5-12 parts of a high-temperature inorganic binder, 2-4 parts of water glass and 0.5-2 parts of a low-temperature organic binder, wherein the mass concentration of the water glass is 1.3-1.5 g / cm<3>. The preparation method can improve the strength of a green body in the sintering process and the utilization rate of the ceramic tile waste ceramic particles and reduce the cost of the binder; the prepared water-permeable ceramic brick has high compressive and bending strength.

Description

technical field [0001] The invention belongs to the technical field of inorganic non-metallic materials, and particularly provides a preparation method of ceramic permeable bricks. Background technique [0002] In recent years, due to the country's advocacy and the improvement of people's awareness of environmental protection, the application of permeable bricks has become more and more common. Ceramic permeable bricks are processed and sintered from construction and industrial waste, and have the characteristics of high strength and good water permeability. Compared with the small raw materials used in general floor tiles, ceramic permeable bricks are formed with large particles of 0.5 to 3.5 mm, so special binders are required for bonding. Most of the binders used in ceramic permeable bricks currently on the market are CMC, Organic binders such as dextrin, although these binders have good effects, are expensive, and they basically volatilize completely at about 500°C, losi...
