The invention relates to the seepage and antiskid colorful tiles made of pyrite cinder and their preparation method. The materials include pyrite cinder, fly ash, water and sediment, electric lime, water fine sand, pebble, stone powder, ordinary portland cement, white cement, complex early strength activator and water. Dry the pyrite cinder and crush it into 100-200 orders powder. Malaxate 10-60% pyrite cinder, 0-60% water fine sand, 20-40% white cement and 4-8% water to get the pavement surface mixtures. Malaxate 25-30% fly ash, 10-30% water and sediment, 5-15% electric lime, 15-30% pebble, 10-15% stone powder, 5-10% ordinary portland cement, 1.5-2.0% complex early strength activator and 8-12% water to get bottom mixtures. Spread the pavement surface and bottom mixtures into the die, pressure molding, demould, stay, palletize and maintain to get the seepage and antiskid colorful tiles made of pyrite cinder. The invention takes full advantages of the color property of the pyrite cinder and the gelling property of the fly ash, water and sediment and electric lime, which changes waste into valuables. Its products have competitive price, light mass, seepage, antiskid, high strength, energy saving and environmental protection.
