Embodiment 1

[0023] A method for preparing a ceramic panel with water-permeable and water-retaining properties, characterized in that 45 parts by weight of raw material glassy slag, 45 parts of clay minerals, 9 parts of rice husks, 18 parts of water, carboxymethyl cellulose 10 parts are mixed, kneaded, and then rolled out in a cylindrical shape with a vacuum kneader, made on a flat plate using a roller rolling machine, after being irradiated by far infrared rays, dried in a drying oven, and finally sintered at a temperature in the range of 1000°C. After sintering, pass on the surface Grinding with sandpaper, etc., to obtain a finished product.

[0024] The particle size of the rice husk is less than 1mm, the particle size of the glassy slag is less than 0.5mm, and the glassy slag with a particle size of less than 0.15mm accounts for 20% of the total glassy slag weight.

[0025] The glassy slag is garbage molten slag.

Embodiment 2

[0027] A method for preparing a ceramic panel with water-permeable and water-retaining properties, characterized in that 20 parts by weight of raw material glassy slag, 70 parts of clay minerals, 0.5 parts of rice husk, 20 parts of water, carboxymethyl cellulose 10 parts are mixed, kneaded, and then rolled out in a cylindrical shape with a vacuum kneader, made on a flat plate using a roller rolling machine, after being irradiated by far infrared rays, dried in a drying oven, and finally sintered at a temperature in the range of 900°C. After sintering, pass on the surface Grinding with sandpaper, etc., to obtain a finished product.

[0028] The particle size of the rice husk is 0.8mm, the particle size of the glassy slag is less than 0.5mm, and the glassy slag with a particle size of less than 0.15mm accounts for 10% of the total glassy slag weight.

[0029] The glassy slag is a mixture of garbage melting slag and sewage sludge melting slag.

Embodiment 3

[0031] A method for preparing a ceramic panel with water permeability and water retention performance, characterized in that 70 parts by weight of raw material glassy slag, 20 parts of clay minerals, 10 parts of rice husk, 15 parts of water, and 15 parts of water glass are mixed , kneading, and then use a vacuum kneader to roll out in a cylindrical shape, and use a roller rolling machine on a flat plate to make it. After being irradiated by far-infrared rays, it is dried in a drying oven, and finally sintered at a temperature in the range of 1200 ° C. After sintering, use sandpaper on the surface. Tried to get the finished product.

[0032] The particle size of the rice husk is less than 1mm, the particle size of the glassy slag is less than 0.5mm, and the glassy slag with a particle size of less than 0.15mm accounts for 40% of the total glassy slag weight.

[0033] The glassy slag is a favorable quality slag generated during metal smelting.

Abstract

The invention provides a ceramic panel having water permeation and retention performances and a preparation method thereof and belongs to the technical field of ceramic materials. The ceramic panel is prepared from, by weight, 20-70 parts of glassy state ore slag, 20-70 parts of clay minerals, 0.5-10 parts of rice hull, and 2-15 parts of a press-moulding aid. The rice hull for producing the ceramic panel has the water permeation and retention performances so that continuous bubbling is generated and the ceramic panel being light in weight and high in strength, being heat insulating and having high quality can be produced at low cost. The ceramic panel is used for urban construction and belongs to a large-size ceramic sheet material that can improve rain drainage through the water permeation and retention performances. Through the sheet material, not only is load on water drainage equipment reduced when rainwater is gathered, but also temperature increase of the city in summer is inhibited by evaporation due to the retained water in the sheet material.

Description

technical field [0001] The invention discloses a ceramic panel with water permeability and water retention performance and a preparation method thereof, belonging to the technical field of preparation of ceramic materials. Background technique [0002] Improving global warming has become a worldwide issue. Among them, alleviating the urban heat island phenomenon, solving the urban instant drainage problem, and directly reducing the degree of damage to the city due to rainwater. Ceramic plates. [0003] The recent recycling of industrial waste has prompted us to develop products with strong water permeability and water retention using recycled resources. For example, permeable bricks have a permeability coefficient of 0.05cm / sec and a water absorption of 38%, and related red bricks have a permeability coefficient of 0.0002cm / sec and a water absorption of 71%. Products made for the purpose of water permeability have very high (expensive) water permeability , but its water re...
