Core-film integrated powder core material vacuum insulation panel and preparation method thereof
The invention discloses a core-film integrated powder core material vacuum insulation panel and a preparation method thereof, and belongs to the technical field of building materials. The vacuum insulation panel structurally comprises a powder core material, a coating bag, a grid material and a high-barrier composite film, the grid material is bound with the powder core material and the coating bag to form an integral panel, the integral panel is placed in the high-barrier composite film to be vacuumized, and the high-barrier composite film is fixed to the grid material after hot melting. According to the vacuum insulation panel and the preparation thereof, the problem of potential engineering safety hazards caused by separation between a filling core material and a high-barrier compositefilm due to the fact that the high-barrier composite film of an existing powder core material vacuum insulation panel is easily punctured in the transportation, storage and construction processes is solved, and on the premise that the extremely low heat conductivity coefficient is guaranteed, the powder core material, the core material coating bag, the grid material and the high-barrier compositefilm are bonded into a whole without separation; and the preparation method is simple and convenient to popularize and apply.
本发明公开了一种芯膜一体的粉体芯材真空绝热板及其制备方法，属于建筑材料技术领域。该真空绝热板结构上包括粉体芯材、包覆袋、网格材料和高阻隔性复合膜，网格材料通过捆扎装订与粉体芯材、包覆袋成为一个整体板材，整体板材置于高阻隔性复合膜内抽真空，高阻隔性复合膜热熔后固定在网格材料上；本发明的真空绝热板解决了现有粉体芯材的真空绝热板在运输、存放以及施工过程中高阻隔性复合膜容易被刺破，使得填充芯材和高阻隔性复合膜的分离而导致的工程安全隐患问题，在保证具有极低的导热系数的前提下，使得粉体芯材、芯材包覆袋和网格材料以及高阻隔性复合膜粘接一体不分离，制备方法简单，便于推广和应用。
