Description
Technical Field
The invention relates to a heat insulation material, in particular to a vacuum heat insulation plate.
Background
The vacuum insulation panel (VIP panel) is one of vacuum insulation materials, is formed by compounding a filling core material and a vacuum protection surface layer, and effectively avoids heat transfer caused by air convection, so that the heat conductivity coefficient can be greatly reduced to 0.002-0.004 w/m.k, which is 1/10 of the heat conductivity coefficient of the traditional insulation material.
The vacuum insulation consists of core insulation, gas adsorbent, desiccant and barrier membrane. The core material and the barrier film are vacuumized, and the heat transfer of gas in the heat insulation plate is reduced, so that the heat insulation effect is achieved.
The existing manufacturing process of the vacuum insulation panel mainly adopts the steps that firstly, a barrier film is manufactured into a bag with an opening on one side, then a core material made of glass fiber is put into the bag, the whole body is put into a vacuum chamber for vacuumizing, and after the required vacuum degree is reached, the edge sealing is heated and sealed.
The prior art has the following disadvantages:
1. the vacuum pumping is difficult: in order to obtain a vacuum insulation panel with a relatively small heat conductivity coefficient, the inside of the barrier film must be vacuumized to a relatively low vacuum degree, and after the vacuum insulation panel is vacuumized to a certain vacuum degree, gas comes out of the bag randomly through free movement of gas molecules (rather than flowing out through pressure difference). The folded edge damages the structure of the barrier film to cause leakage rate; the barrier film is vacuumized and packaged by the prior art, an edge seal is inevitably formed in the middle of the periphery of the vacuum insulation panel, and the vacuum insulation panel needs to be attached to the surface of a refrigerator shell or other refrigeration equipment in the use process of the vacuum insulation panel, so that the edge seal needs to be folded to the surface of the insulation panel to form a regular shape. Because the barrier film has certain hardness, the barrier film can form a plurality of tiny air holes in the folding process of the barrier film, so that external air can enter, and the service life of the vacuum insulation panel is greatly influenced. Even when a relatively large leak rate is formed, the heat insulation plate can enter a large amount of gas, and the heat conductivity coefficient is greatly increased, so that the heat insulation plate directly fails.
2. Overlong edge sealing: because the core material made of the glass fiber has higher filling power, in order to meet the bagging process, the bag needs to be made larger, the core material can be put into the bag, and the bag is inevitably subjected to vacuum-pumping compression to form a longer edge sealing. Such a manufacturing process also results in waste of barrier film material.
