Abstract

The invention discloses a low-temperature sintered ceramic glazed tile and preparation method thereof. The ceramic glazed tile comprises a tile blank, a top glaze layer, and a print glaze layer. In tile blank component raw materials, petalite (LiAlSi4O10) is adopted as a tile blank temperature-reducing material. A product is obtained through the steps of blending, ball milling and sieving, drying, press-molding, top glaze applying, roller printing, print glaze applying, and sintering. Sintering temperatures are that: sintering is carried out for 15-20min at a temperature of 970 DEG C when the material is delivered into a kiln; sintering is carried out for 20-25min at a temperature of 970-1150 DEG C; sintering is carried out for 5-10min at a temperature of 1150-1200 DEG C; temperature is maintained for 5-10min at 1200 DEG C; and sintering is carried out for 20-25min at a temperature of 1200-150 DEG C. According to the invention, lithium feldspar in lithium ore tailings is adopted as a tile blank temperature reducing material, such that defects of high sintering temperature and long sintering time of glazed tile in prior arts are overcome. Therefore, glazed tile low-temperature fast sintering is realized, energy consumption is reduced, and resource utilization rate is improved.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a low-temperature fired ceramic glazed tile and a preparation method thereof. Background technique [0002] Judging from the current production cost ratio of building and sanitary ceramic products worldwide, fuel costs account for the largest proportion of production costs, and have already reached more than 40% of the total energy consumption of ceramic industries in various countries. At present, the development of the building and sanitary ceramics industry in the world has been constrained by high energy consumption. Since the prices of oil, electricity, gas and coal have continued to rise in the past 20 years, the development speed of the ceramic industry has also been curbed. There are also many domestic ceramic enterprises due to high energy consumption costs, resulting in rising product prices and reducing market competitiveness. [0003] Moreover, in addition to being...
