Medium- and low-temperature environment-friendly ceramic tile and preparation method thereof

The invention relates to a medium- and low-temperature environment-friendly ceramic tile. The ceramic tile is prepared from the following components in parts by weight: 8-13 parts of nontronite, 19-25parts of Jiani (a kind of Yixing clay), 6-11 parts of bauxite clinker, 0.5-1.2 parts of white agate, 1-3 parts of sodium chloride, 4-7 parts of chalkstone, 8-14 parts of quartz, 2-5 parts of wollastonite, 5-10 parts of white clay, 7-12 parts of Jiepai soil, 3-6 parts of expanded perlite and 1-2 parts of graphite fiber. The prepared ceramic tile is high in ceramic surface strength and smooth in hand feeling, the water absorption rate is lower than 0.5%, scratches and cracks are not prone to being generated, and the quality of the ceramic tile can be comparable to that of high-temperature ceramic; and due to the fact that medium- and low-temperature firing is adopted and firing time is short, energy consumption and cost are greatly reduced, and environmental pollution is reduced. 本发明涉及一种中低温环保瓷砖，由以下重量份数的各组分组成：绿脱石8～1
