Vacuum insulated panel and preparation method thereof
The invention provides a vacuum insulation panel and a preparation method thereof, and belongs to the technical field of thermal insulation materials. According to the composite film, the PE serves as a protective layer, and the aluminum foil and at least one of the PA film, the PVDC film, the EVOH film, the TIE film and the PET film serve as the barrier layer, so that the heat insulation effect of the plate is improved; preparing the composite film into a rectangular groove array structure, then adding core board particles and a bagged getter to obtain second structural bodies, placing the two second structural bodies with the same structure in a mirroring manner, and then sealing and vacuumizing, so that nanopores can be formed in the vacuumizing process by controlling the raw material composition of the core board particles; the nano-pores are insensitive to vacuum air pressure, so that independent honeycomb vacuum units exist in the plate, and the heat insulation effect of the plate is further improved; and finally, one or more third structural bodies are assembled in a multi-layer manner, so that the number of the honeycomb vacuum units is further increased, and the heat conductivity coefficient can be reduced while an opacifying agent is omitted.
本发明提供了一种真空绝热板及其制备方法，属于保温材料技术领域。本发明的复合膜以PE作为保护层，以铝箔和PA膜、PVDC膜、EVOH膜、TIE膜和PET膜中的至少一种作为阻隔层，提高板材的隔热效果；再将复合膜制备成矩形凹槽阵列结构，随后将芯板颗粒和袋装吸气剂加入，得到第二结构体，再将两个相同结构的第二结构体镜像放置，然后进行密封和抽真空，通过控制芯板颗粒的原料组成，能够在抽真空过程中形成纳米孔隙，利用纳米孔隙对真空气压不敏感使得板材内部存在独立的蜂窝真空单元，进一步提高板材的隔热效果；最后将一个或多个第三结构体进行多层组装进一步增加了蜂窝真空单元的数量，能够在省略遮光剂的同时降低导热系数。
