Abstract

The invention discloses a porcelain tile with high polishing waste content. The porcelain tile comprises the following components by mass percentage: 30-70% of polished ceramic waste, 10-30% of clay,10-25% of sandstone, 10-15% of a low temperature material, 1-10% of a high temperature deoxidizing agent, and 0.3-0.8% of an additive. According to the invention, the high temperature deoxidizing agent is introduced into the formula, the high temperature deoxidizing agent consumes the oxygen around silicon carbide particles in the polished waste to inhibit oxidation of silicon carbide in the polished waste, thus realizing densification application of the polished waste. The prepared porcelain tile has a water absorption rate controlled at 0.5% or below and a shrinkage rate controllable in therange of 5%-15%. The porcelain tile provided by the invention achieves efficient resource utilization of polished ceramic waste, reduces the raw material cost of porcelain tile production, and has high polished waste utilization rate and wide applicability. The preparation method provided by the invention has no need to change the porcelain tile production process and add new equipment, the technology is simple and is easy for industrialization.

Description

technical field [0001] The invention relates to the field of architectural ceramics, in particular to the utilization of ceramic tile polishing waste. Background technique [0002] With the rapid development of my country's ceramic industry, the output of ceramic industry waste, especially polishing waste, which accounts for more than 60%, has also increased sharply. Due to the complex composition of polishing waste, more than 80% of the polishing waste in the industry cannot be recycled. At present, the processing methods of polishing waste are mainly concentrated stacking and landfilling, which not only wastes precious mineral resources, but also occupies land and pollutes water and soil resources. Therefore, polishing waste not only exerts great pressure on the environment, but also restricts the sustainable development of the building ceramics industry. [0003] At present, the recycling of polishing waste is mainly focused on the production of lightweight ceramic tile...
