Abstract

The application relates to a preparation method and application of a vacuum insulation panel, and belongs to the technical field of heat insulation materials. The method comprises the steps of providing a film material and at least one vacuum heat-insulating core material, bonding one surface of the vacuum heat-insulating core material to the film material, bonding the film material to the other surface of the vacuum heat-insulating core material under a vacuum environment, and packaging the film material around the vacuum heat-insulating core material, so that the vacuum heat-insulating core material is sealed in a vacuum cavity formed by the film material, and thus the vacuum heat-insulating plate is obtained. According to the application, for a plurality of vacuum heat-insulating core materials, the traditional scheme needs to bag and vacuumize each vacuum heat-insulating core material independently, but the application does not need to bag the film material, and after one surface of the vacuum heat-insulating core material is attached to the film material, the other surface of the vacuum heat-insulating core material is directly attached to the film material and packaged in a vacuum environment, so that operations such as bag making of the film material, bagging of the vacuum heat-insulating core material, vacuumize and the like are not needed, and the steps are simpler.
