Thermal-insulating material composition and thermal-insulating pad and preparation method thereof and electric cooking appliance

The invention discloses a preparation method of a thermal-insulating material composition and a thermal-insulating pad, a thermal-insulating pad prepared by using the preparation method of the thermal-insulating pad, and an electric cooking appliance with the thermal-insulating pad. The thermal-insulating material composition comprises the following components in percentage by weight: 20-70% of gas-phase method silica and 2-20% of a high-silica fiber. By adopting the technical scheme of the invention, the thermal-insulating pad has the advantages of good thermal insulation effect, low moistureabsorption rate and low packaging cost. 本发明公开种隔热材料组合物、种隔热垫的制备方法、由该隔热垫的制备方法制得的隔热垫、及应用该隔热垫的烹饪电器。其中，按重量百分比计，所述隔热材料组合物包括气相法二氧化硅，20％-70％；高硅氧纤维，2％-20％。本发明的技术方案制备的隔热垫具有隔热效果好、吸湿率低及包装成本低的优点。
