Problems solved by technology

In 2013, General Secretary Xi Jinping put forward the "sponge city" urban construction strategic policy. The construction of "sponge city" is a kind of "burden reduction" and "supplement" to the traditional drainage system. The most effective measure is to use water-permeable and moisturizing properties. Permeable bricks pave roads, especially sidewalks, parking lots, squares, sports fields, etc. The performance is poor, and the molding process of sintered ceramic permeable bricks with superior performance above is particularly difficult. When molding, the green body must have a certain strength, and the proportion of small particles in the particle size distribution must be relatively large, but this will block the gap between the particles. Therefore, it is necessary to invent a permeable brick with good formability and strong water permeability.

Abstract

The invention belongs to the technical field of ceramic flooring tiles and in particular relates to an environmental-friendly permeable ceramic brick and a preparation method thereof. The permeable ceramic brick comprises the following components in percentage by mass: 60-80% of waste ceramic chip granules of the ceramic brick, 5-10% of a high-temperature inorganic adhesive, 5-10% of a fluxing agent, 10-20% of a pore forming agent and a low-temperature organic adhesive accounting for 1-1.5% of the mass sum of the previous four basic materials. The preparation method comprises the following steps: mixing all the materials, molding, drying and roasting, thereby obtaining the permeable ceramic brick. The permeable ceramic brick has excellent water permeability, strength and anti-frost property.

Description

technical field [0001] The invention belongs to the technical field of ceramic floor tiles, and in particular relates to an environment-friendly ceramic permeable brick and a preparation method thereof. Background technique [0002] With the construction of urbanization, a large number of impermeable building grounds have replaced the original forests and fields, causing "urban desertification" and accelerating the urban "heat island effect". In 2013, General Secretary Xi Jinping put forward the "sponge city" urban construction strategic policy. The construction of "sponge city" is a kind of "burden reduction" and "supplement" to the traditional drainage system. The most effective measure is to use water-permeable and moisturizing properties. Permeable bricks pave roads, especially sidewalks, parking lots, squares, sports fields, etc. The performance is poor, and the molding process of sintered ceramic permeable bricks with superior performance above is particularly difficu...
