Abstract

The invention belongs to the technical field of building materials, and particularly relates to a polished tile and a making method thereof. The polished tile comprises, by weight, 4%-20% of kaolin, 2%-8% of bentonite, 6%-50% of potassium feldspar, 3%-25% of albite, 1%-6% of crushed waste bricks, 1%-25% of sediment mud, 2%-18% of pyrophyllite, 1%-8% of high diaspore and 1%-12% of silica sand. According to the polished tile and the making method, solid waste generated in the polished tile production process is used to the maximum degree, the using rate of the raw materials in the polished tile production process is used to the maximum degree, solid waste discharging in the polished tile production process is accordingly reduced, and mineral resource waste and the pressure on the environment in the polished tile production process are reduced.

Description

technical field [0001] The invention belongs to the technical field of building materials, and particularly relates to a polished tile and a preparation method thereof. Background technique [0002] The shortage of energy and resources is a century-old problem faced by human beings at present. The resulting energy and resource crisis has attracted widespread attention from countries around the world on energy conservation and consumption reduction, energy conservation and consumption reduction technologies and low-carbon economy. As an industry with high resource consumption, high energy consumption and high pollution, the construction industry should conform to the trend of the times, develop new technologies for energy conservation and consumption reduction, and promote the realization of my country's energy conservation, material conservation and emission reduction goals. [0003] Sedimentation mud refers to the sum of various waste residues of polishing lines in polished...
