Description

Cutting assembly type vacuum insulation panel and preparation method thereof
Technical Field
The utility model relates to the technical field of vacuum insulation panels, in particular to a cuttable vacuum insulation panel and a preparation method thereof.
Background
The vacuum heat insulating plate is a heat insulating material manufactured by utilizing a vacuum heat insulating principle, and the principle is that the heat convection of air in the plate and the heat conduction between gases are reduced by improving the vacuum degree in the plate, so that the effects of better energy conservation and heat preservation are achieved. The vacuum heat insulation plate has very low heat conductivity, the heat conductivity coefficient is about 1/10 of that of a common heat insulation material, and the thickness of the vacuum heat insulation plate is only about 1/7 of that of the common heat insulation material, so the vacuum heat insulation plate is widely applied to the fields of aerospace, refrigerated transportation, food industry, medical heat insulation, buildings and the like.
For the vacuum insulation panel, the air is pumped away, so that the air mean free path is larger than the aperture, and the heat conduction of the gas can be greatly inhibited. However, vacuum insulation panels have only one enclosure to protect the vacuum, are easily damaged, and cannot be cut in the field because any damage to the panel can result in a loss of vacuum, thereby degrading the insulation performance.
Chinese utility model CN201821582751.9 discloses a honeycomb type cuttable and bendable vacuum insulation panel, which comprises a bottom plate, a core plate and a surface plate, wherein the bottom plate, the core plate and the surface plate are sequentially arranged from bottom to top in vertical height, the upper surface of the bottom plate is provided with a plurality of grooves, the grooves are provided with a plurality of core materials to form the core plate, the bottom plate, the core plate and the surface plate are vacuumized and the bottom plate and the surface plate are heated and pressed into a whole. The utility model utilizes the honeycomb structure principle to make the vacuum insulated panel into a plurality of independent vacuum units at any angle and any direction, can realize the arbitrary cutting of the X axis and the Y axis, and the more the vacuum units, the less the loss of the vacuum effect after the cutting,
the utility model discloses a manufacturing and cutting method of a multi-section long-strip-shaped vacuum heat-insulating plate, which comprises the steps of drying a plurality of core materials with the same specification, arranging the core materials in a row side by side after taking out the core materials, loading the core materials into vacuum barrier film bags, adjusting the distance between the core materials, sealing the core materials into a plurality of sections of long-strip-shaped vacuum heat-insulating plates, taking out the vacuum barrier film bags, leveling film materials between the core materials, aligning the sealing, heat-sealing the film bags between the core materials, sealing the film bags between the core materials in sequence, separating the sections of long-strip-shaped vacuum heat-insulating plates into a plurality of small vacuum heat-insulating plates, cutting the sections of long-strip-shaped vacuum heat-insulating plates into a plurality of small vacuum heat-insulating plates by using a cutter in the sealing middle between the small vacuum heat-insulating plates, and cutting the small vacuum heat-insulating plates.
Aluminum honeycomb is often used for filling core materials, but aluminum alloy raw materials adopted by the aluminum honeycomb are large in heat conductivity coefficient, and the heat conductivity coefficient of the manufactured vacuum insulation panel is difficult to meet related requirements. The wall thickness of the common upper and lower open-pore honeycombs is smaller, so that the problem that the honeycombs and the surface aluminum plastic film are not tightly sealed exists, and the honeycombs are difficult to form independent vacuum units; the wall thickness is increased to form a plastic frame, so that the cost is increased, and the heat conductivity coefficient is improved; the core material in the honeycomb after cutting is also cut, so that powder leaks and damage is caused.
