Technical Field
The utility model belongs to the technical field of thermal-insulated heat preservation, concretely relates to honeycomb aerogel structure vacuum insulation panels.
Background
The Vacuum Insulated Panel (VIP) is a super-insulated heat-insulating material, and has the advantages of thin thickness, small volume and light weight of the heat-insulating layer when meeting the same heat-insulating technical requirements due to extremely low heat conductivity coefficient, so that the Vacuum Insulated Panel (VIP) is suitable for occasions with higher energy-saving requirements and requirements on small volume, light weight and greater technical and economic significance of the heat-insulating material.
Generally, a vacuum insulation panel is composed of a core material, a coating material, and a getter. The coating material can maintain the internal vacuum state for coating the core material, and can prevent the permeation of external air during the use process of the vacuum heat-insulating plate, thereby prolonging the service life of the vacuum heat-insulating plate.
The insulation requirements of vacuum insulation panels are becoming increasingly high on the market, and in order to improve the insulation properties of the panels, the thermal conductivity of VIP products is currently improved by reducing the density of the core, which, although reducing the cost of VIP production, makes the core less robust and more prone to breakage and therefore more difficult to handle during multiple production stages. At too great a reduction in density, the resulting VIP panels have poor dimensional stability, the edges of the panels collapse, and the edge panel envelope wrinkles. Therefore, it is necessary to improve the mechanical properties of the core of the insulation panel on the basis of ensuring the thermal properties and to ensure the dimensional stability of the insulation panel.
Therefore, it is necessary to design a vacuum insulation panel having high thermal insulation performance and better mechanical performance.
