The invention discloses a kaolin porcelain body capable of preventing porcelain body deformation, the kaolin porcelain body is prepared from a porcelain body base material and a porcelain body additive, the porcelain body base material comprises the following raw materials by mass: 55-65 wt% of kaolin, 25-35 wt% of modified albite, 5-15 wt% of fused quartz, 1-3 wt% of cooked talc, and 3-10 wt% of alumina micro powder; the ceramic green body additive comprises a tackifying and anti-reflection agent and a toughening and reinforcing agent, the addition amount of the tackifying and anti-reflection agent is 6-10 wt% of the total mass of the green body base material, and the addition amount of the toughening and reinforcing agent is 10-16 wt% of the total mass of the green body base material. According to the invention, after the albite is powdered, Na2O in the powdered albite can form Na2O2 with high thermal stability at high oxygen and high temperature, and the modified albite containing Na2O2 can prevent the Na2O from reacting at high temperature, so that the situation that the viscosity is sharply reduced is avoided, and the deformation of the porcelain body is prevented.
本发明公开了一种防止瓷胎变形的高岭土瓷坯体，由瓷坯体基料和瓷坯体添加剂制得，其中所述瓷坯体基料由按照质量百分比计的如下原料组成：高岭土55～65wt％、改性钠长石25～35wt％、熔融石英5～15wt％、熟滑石1～3wt％、氧化铝微粉3～10wt％；所述瓷坯体添加剂为增粘增透剂和增韧增强剂，所述增粘增透剂的添加量为坯体基料总质量的6～10wt％，增韧增强剂的添加量为坯体基料总质量的10～16wt％。本发明通过将钠长石进行粉末化后，在高氧高温下，使得粉末钠长石中的Na2O可形成热稳定性高的Na2O2，含有Na2O2的改性钠长石可避免了Na2O在高温下产生反应，进而产生粘度急剧下降的情况，防止了瓷胎变形。
