Embodiment Construction

[0015] A stain-resistant ceramic permeable floor tile for urban pavement, prepared from the following raw materials in parts by weight (kg): sewage plant sludge 40, rice husk 6, potassium feldspar powder 4, fly ash 10, water glass 10, Wei Crystal 18, quartz sand 6, silicon nitride 8, titanium dioxide 3, zirconia 5, aluminum dihydrogen phosphate 4, pregelatinized starch 2.

[0016] Said a kind of anti-contamination ceramic permeable floor tile for urban pavement is made by the following specific steps:

[0017] (1) Naturally dry the sludge from the sewage plant, pulverize and pass through a 200-mesh sieve to obtain sludge powder for use; mix half of the sludge powder, rice husk, and potassium feldspar powder, add an appropriate amount of water, and put it into a mixer Stir at a speed of 120 rpm to form sludge, control the water content to 20%, and then send it to a granulator for extrusion and granulation to obtain sludge granules, and control the particle size to 10 mesh;

Abstract

The invention discloses an anti-staining ceramic permeable floor tile for city roads. The anti-staining ceramic permeable floor tile is prepared from the following raw materials in parts by weight: 40-43 parts of sludge from a sewage plant, 6-7 parts of rice hulls, 4-5 parts of feldspar powder, 10-12 parts of fly ash, 10-12 parts of water glass, 18-20 parts of pegmatite, 6-7 parts of quartz sand, 8-9 parts of silicon nitride, 3-4 parts of titanium dioxide, 5-6 parts of zirconium oxide, 4-5 parts of aluminum dihydrogen phosphate and 2-3 parts of pregelatinized starch. The floor tile disclosed by the invention is prepared by adding the components such as pegmatite, titanium dioxide and zirconium dioxide through a series of sintering processes, the compactness and porosity of the product are improved, and the product has high strength, bright and clean surface, high anti-staining property and good permeability and is suitable for gardens, playgrounds and city roads.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a stain-resistant ceramic permeable floor tile for urban pavement. Background technique [0002] Sponge city refers to a city that can be like a sponge and has good "elasticity" in adapting to environmental changes and responding to natural disasters. use. In the process of sponge city construction, the systematic nature of natural precipitation, surface water and groundwater should be coordinated, water supply, drainage and other water recycling links should be coordinated, and its complexity and long-term nature should be considered. As we all know, most of the existing urban street pavements are paved with impermeable materials such as cement concrete, asphalt, stone, and ceramic tiles. This hardened pavement is no longer suitable for the trend of building sponge city pavements. [0003] Permeable bricks have good water permeability and moisturizing properties, wh...
