Problems solved by technology

Due to the use of local clay raw materials and firing at a low temperature below 1100°C, traditional terracotta tiles have high water absorption (above 10% water absorption) and low strength, and cannot be used in severe cold (minus 30°C). Clay is used as raw material, which is easy to cause environmental problems such as soil erosion and reduction of cultivated land.

Abstract

The invention discloses a low-temperature sintered terracotta blank and a preparation method thereof. The preparation method comprises the following steps: by taking waste terracotta, shale and clay as raw materials, uniformly processing, and mixing; the low-temperature sintered terracotta blank comprises the following raw materials in parts by weight: 0-80 parts of clay, 0-20 parts of waste terracotta and 15-50 parts of shale. The blank is fast in low-temperature sintering speed, high in sintering degree, low in water absorption, and high in strength, and sintered products can be used under severely cold weather condition.

Description

technical field [0001] The invention relates to the technical field of ceramic production, in particular to a low-temperature sintered ceramic tile blank and a preparation method thereof. Background technique [0002] The history of terracotta tiles has a long history in China, dating back to the Han Dynasty. In the archaeological circles, there is the saying of Thai bricks and Han tiles. Traditional terracotta tiles have a classical, natural and simple artistic beauty, and are deeply loved by people. However, most traditional terracotta tiles are They are fired at a low temperature below 1100°C, and the firing time is more than 15 hours. Due to the use of local clay raw materials and firing at a low temperature below 1100°C, traditional terracotta tiles have high water absorption (more than 10% water absorption) and low strength, and cannot be used in severe cold (minus 30°C). Clay is used as a blank, which is likely to cause environmental problems such as soil erosion and...
