Preparation method of jade glaze daily porcelain with high thermal stability and high strength

The invention provides a preparation method of jade glaze daily porcelain with high thermal stability and high strength. Raw materials of the formula comprise a SiO2 mineral, an AL203 mineral, a K20 mineral, a B203 mineral, a ZnO mineral, a boron-zinc frit, a zirconium white frit and a solvent. The preparation method comprises the following steps of: a, burdening, ball-milling and mixing; b, refining and ageing; c, blank forming; d, drying and cooling; e, glazing and glaze firing; and f, finished product detecting and discharging. Through cooperation of the above procedures, the proportion ofporcelain raw materials can be changed by adding the boron-zinc frit and the zirconium white frit; the reaction among the porcelain raw materials is better; moreover, crystal phase development compactness is promoted, refractory substances such as free quartz are reduced, the density of the porcelain body is improved, cracking of a porcelain finished product in the firing process is prevented, thestrength of the porcelain
