The invention discloses a preparation method of a high-temperature-resistant lightweight ceramic heat screen. The method comprises the following steps: a, preparing a colloidal ceramic modifier of glass fiber cloth; b, immersing glass fiber cloth into the colloidal ceramic modifier, taking out the glass fiber cloth, and baking and pre-curing the glass fiber cloth at 100-110 DEG C to obtain modified pre-impregnated cloth of the glass fiber cloth; c, the modified prepreg is wound and formed on a mold of a winding machine in a multi-layer mode, then demolding is conducted, and a primary cylindrical profile is obtained; d, putting a product obtained in the step c into a heating furnace, sealing, and then pressurizing into the heating furnace to obtain a cured cylindrical profile; and e, putting the product obtained in the step d into a high-temperature furnace, heating to 1500-1800 DEG C, preserving heat for 4 hours, cooling along with the furnace, cooling to 150-250 DEG C, and discharging to obtain the high-temperature-resistant light ceramic heat insulation screen.
本发明公开了一种耐高温轻质陶瓷隔热屏的制备方法。其步骤是：a.制备玻璃纤维布的胶态陶瓷改性剂；b.将玻璃纤维布浸入胶态陶瓷改性剂后取出，在100℃～110℃烘烤预固化，得玻璃纤维布的改性预浸布；c.改性预浸布在缠绕机的模具上多层缠绕成型，然后脱模得初步筒形型材；d.将步骤c的得品置入加热炉中密闭后升压加热炉内得固化筒形型材；e.将步骤d的得品置入高温炉内，升温至1500℃～1800℃，保温4小时，随炉冷却，降温至150℃～250℃出炉，得耐高温轻质陶瓷隔热屏。
