| 目的 利用气凝胶/硅酸铝纤维制备一种保温包装材料，并研究其导热性能。方法 利用真空抽滤成型方法及微波加热的干燥方法制备保温包装材料，利用正交试验得到影响该保温包装材料的主要因素。结果 导热系数测定结果表明，正交实验最佳配方的导热系数为0.0164 W/(m•K)，符合温控包装要求。随着二氧化硅气凝胶加入量的增大，导热系数变小；在最佳体积密度范围51.29~55.09 mg/cm3内，材料的导热系数最低可达到0.013 W/(m•K)。结论 文中方法扩大了气凝胶和硅酸铝纤维材料在包装行业中的应用范围，对于农产品包装具有一定现实意义。 |
| 英文摘要: |
| The work aims to prepare a kind of thermal insulation packaging material with the aerogels/aluminum silicate fiber, and study its thermal conductivity. The thermal insulation packaging material was formed by the vacuum filtration and dried by the microwave heating. The major factor that affected such thermal insulation packaging material was obtained by the orthogonal experiment. The measured results of the thermal conductivity indicated that, the heat conductivity coefficient of the optimal formula in the orthogonal experiment was 0.0164 W/(m•K) and conformed to the temperature-controlled packaging requirements. The heat conductivity coefficient decreased with the addition of silica aerogel. The heat conductivity coefficient of the material could reach 0.013 W/(m•K) to the minimum within the optimal volume density range of 51.29~55.09 mg/cm3. The proposed method expands the application range of aerogels and aluminum silicate fiber material in the packaging industry, and such application has certain practical significance for the agricultural product packaging. |
