Therefore, there is still a need for a composite thermal insulation mica plate structure and a method for preparing the same to solve the above-mentioned problems. Disclosure of utility model The utility model provides a composite heat insulation mica plate structure for solving the problems and a preparation method thereof. The utility model adopts the following technical scheme: a composite heat insulation mica plate structure comprises a sandwich layer and supporting plates respectively positioned at two sides of the sandwich layer, wherein the thickness of each supporting plate is 0.2-0.5mm, and the thickness of the heat insulation sandwich layer in an original state is 0.8-1.5mm. In one embodiment, the compressed thickness of the sandwich layer is 0.4-1mm, and the sandwich layer is a heat insulation sandwich layer or a toughening sandwich layer. In one embodiment, the sandwich layer has an initial thickness to thickness ratio of (1.2-2) 1 after compression. In one embodiment, the method further comprises the step of sequentially combining the sandwich layers and the support plates on any side of the support plates in an alternating distribution sequence. In one embodiment, the number of support plates is 3 and the number of sandwich layers is two. In one embodiment, the number of support plates is 5 and the number of sandwich layers is three. A method for preparing a composite heat-insulating mica plate structure, which is used for preparing the composite heat-insulating mica plate structure according to any one of the above, and comprises the following steps: s1, providing a plurality of support plates and sandwich layers, polishing two sides of the support plate positioned in the middle, and polishing one side of the other two support plates serving as outer walls; S2, coating glue on the polishing surface of the supporting plate serving as the outer wall; S3, attaching a sandwich layer on the supporting plate through glue; s4, attaching another supporting plate to the top of the sandwich layer through glue; s5, hot-pressing the stacked sandwich layer and the support plate; and S6, demolding and taking out the finished product. Preferably, the polishing includes: And (3) polishing one surface of the supporting plate by adopting 200-mesh sand paper, wherein the removal amount is 0.02-0.03mm. Preferably, when the number of support plates of the composite heat insulation mica plate structure is 3, repeating 3 times S3. Preferably, when the number of support plates of the composite heat insulation mica plate structure is 4, S3 is repeated 4 times. Compared with the prior art, the utility model has the beneficial effects that at least: Through experimental verification, the thickness of the supporting plate is 0.2-0.5mm, the thickness of the original state of the heat insulation sandwich layer is 0.8-1.5mm, wherein the heat insulation sandwich layer has elastic performance and stronger tensile toughness, and when the heat insulation sandwich layer is coated on the outer surface of a battery, the heat insulation sandwich layer can provide good anti-damage capability, stably coats the outer surface of the battery pack and has the heat insulation and fire insulation capability.
