Vacuum insulation panel and preparation method thereof
The invention discloses a vacuum insulation panel and a preparation method thereof, the vacuum insulation panel comprises a core material and a composite coating film, and the core material comprisesan inner core and a filter layer coating the outer part of the inner core; the composite coating film comprises an outer wrapping film and a restraint film, and the core material is coated with the outer coating film; the restraint film has a thermal shrinkage effect, wraps the outer portion of the outer wrapping film and is fused with the outer wrapping film into a whole. The exterior of the vacuum insulation panel prepared by the preparation method has self-constraining force, so that the problems of bag expansion and air leakage caused by expansion deformation of the vacuum insulation paneldue to construction puncture or large internal and external temperature difference change are solved, and the problems that a coating film of the vacuum insulation panel is easy to damage and the thermal insulation performance of the vacuum insulation panel is reduced after damage and air leakage are solved; and the super heat insulation performance of the vacuum insulation plate can be maintained for a long time.
本发明公开了一种真空绝热板及其制备方法，其中真空绝热板包括芯材和复合包覆膜，芯材包括内芯和包覆于内芯的外部的过滤层；复合包覆膜包括外包覆膜和约束膜，外包覆膜包覆于芯材的外部；约束膜具有热收缩作用，约束膜包覆于外包覆膜的外部并与外包覆膜熔融为一体。通过该制备方法制得的真空绝热板的外部具有自约束力，避免了真空绝热板因施工刺破或因内外温差变化大造成其膨胀变形发生胀袋漏气问题，并且解决了真空绝热板包覆膜易被破坏及破坏漏气后真空保温板保温性能下降的问题，使真空绝热板长期维持其超级绝热保温性能得到了保障。
