Unit type vacuum heat insulation plate and vacuum heat insulation composite insulation plate based on unit type vacuum heat insulation plate
The invention discloses a unit type vacuum heat insulation plate and a vacuum heat insulation composite heat preservation plate based on the unit type vacuum heat insulation plate, and belongs to the technical field of building heat preservation materials. Each heat preservation unit comprises a unit gas blocking film bag and a block-shaped heat preservation core material packaged in the unit gas blocking film bag, and each unit gas blocking film bag close to the outer gas blocking film piece on the same layer is provided with an extraction opening. And the surface of the unit gas-blocking film bag around the extraction opening is hermetically connected with the adjacent outer gas-blocking film. According to the invention, one surface of each unit air-blocking film bag, which is not provided with an extraction opening, is compounded with the first layer of outer air-blocking film into a whole through a hot-melting pressing process, so that the air-blocking film bag is convenient to carry and turn over; after vacuumizing, the surface of the unit gas blocking film bag around the extraction opening is connected with the second layer of outer gas blocking film in a sealed mode, independent heat preservation units are formed, only the vacuum degree of the corresponding heat preservation units can be damaged during punching or cutting, and the influence on the heat conductivity coefficient of the whole plate is reduced.
本发明公开了一种单元式真空绝热板及基于其的真空绝热复合保温板，属于建筑保温材料技术领域，包括真空密封在外阻气膜袋中的多个保温单元，各保温单元沿板面方向紧密排列；保温单元包括单元阻气膜袋和封装在单元阻气膜袋中的块状保温芯材，在靠近同层外阻气膜片的各个单元阻气膜袋上开设抽气口；抽气口周围的单元阻气膜袋表面与靠近的外阻气膜片密封连接。本发明中，各单元阻气膜袋未开设抽气口的一面通过热熔压合工艺与第一层外阻气膜片复合为一体，方便搬运及翻转；抽真空后，抽气口周围的单元阻气膜袋表面与第二层外阻气膜片密封连接，形成一个个独立的保温单元，在打孔或者切割时只会破坏对应保温单元的真空度，降低了对整板导热系数的影响。
