High-glossiness reinforced magnesia porcelain and preparation method thereof

Abstract

The invention discloses a strengthened magnesia porcelain with high gloss and a preparation method thereof. The strengthened magnesia porcelain is composed of the following raw materials according to mass percentage: 60-70% of talc, 10-15% of Chaozhou bentonite, and 8-8% of Longyan kaolin 10%, quartz 2‑6%, potassium feldspar 5‑12%. Grind talc, Chaozhou bentonite, Longyan kaolin, quartz, and potassium feldspar respectively, pass through a 200‑400 mesh sieve, weigh them according to the mass percentage, and then form, dry, and fire to obtain strengthened magnesia porcelain. The firing temperature range is 1250-1300°C, the holding time is 0.5-8h. The invention adopts natural mineral raw materials, and through repeated batching tests, the raw materials in the magnesia green body are well matched, and the strengthened magnesia porcelain products with good glaze quality and high gloss are produced, and the performances of the reinforced magnesia porcelain products reach GB / T3532‑1995 According to the standard requirements, the whiteness of its products is above 86 degrees, and the edge impact strength is 0.693J / cm 2 . Thermal shock resistance: 180‑20°C without cracking once. It effectively eliminates the pinholes in the glaze and improves the brightness of the glaze, so it has a broad market prospect.
