Core material containing molten salt and application of core material in nano insulation board
The invention relates to the field of heat insulation plates, and provides a core material containing molten salt and application of the core material in a nano heat insulation plate aiming at the problem that the nano heat insulation plate can shrink after being heated. The preparation method of the core material comprises the following steps: (1) uniformly mixing a heat-insulating filler, reinforced fibers, molten salt and an auxiliary agent to obtain a mixed material, wherein the molten salt is a mixture of zinc chloride and aluminum chloride; and (2) carrying out compression molding on the mixed material, then heating to enable the molten salt to generate phase change, and then cooling to obtain the nano heat insulation plate core material. According to the high-latent-heat nano heat insulation plate, the molten salt is heated at high temperature to be molten and permeate into the heat insulation material, and then is cooled and solidified, so that the internal structure is reinforced, the heat insulation performance is further improved, and the prepared high-latent-heat nano heat insulation plate has excellent compression strength and low high-temperature heat conductivity coefficient. The invention further provides application of the core material in the nano heat insulation plate, and the core material is subjected to vacuum packaging to obtain the nano heat insulation plate.
本发明涉及绝热板领域，针对纳米绝热板受热会收缩的问题，提供一种含熔融盐的芯材及其在纳米绝热板中的应用。芯材的制备方法包括以下步骤：（1）将隔热填料、增强纤维、熔融盐和助剂混合均匀得到混合物料，所述熔融盐为氯化锌和氯化铝的混合物；（2）将混合物料压制成型，然后加热使熔融盐发生相变后再冷却，得到纳米绝热板芯材。通过高温加热熔融盐使其熔融，渗透至隔热材料内部，再冷却凝固，从而加固内部结构，进而提供隔热性能，制得的高潜热纳米绝热板具有优良的压缩强度和较低的高温导热系数。本发明还提供芯材在纳米绝热板中的应用，将芯材进行真空封装，得到纳米绝热板。
