Abstract

The invention provides an opening hemming 3D vacuum heat insulation plate. The vacuum heat insulation plate is provided with a containing cavity and an opening communicating with the containing cavity; the vacuum insulation plate specifically comprises an inner barrier layer, a middle core material and an outer barrier layer; the inner barrier layer extends outwards in the radial direction of theopening at the opening position and then is folded downwards in the axial direction of the opening to form hemming; the side, close to the opening, of the outer barrier layer extends upwards in the axial direction of the opening, extends towards the inner barrier layer in the opening direction and then extends upwards in the axial direction of the opening to form an extending face, and at least one part of the outer side face of the extending face is wrapped by the hemming; and a sealing material is arranged between the hemming and the extending face. The vacuum insulation plate has no marginal effect and cold bridge, greatly enhances the heat preservation performance, and prolongs the heat preservation time, so that the cost performance of VIP application is improved, and the vacuum insulation plate is more energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the field of thermal insulation materials, in particular to a 3D vacuum insulation panel. Background technique [0002] At present, most vacuum insulation panels are two-dimensional flat plates, and there are also VIP panels that roll flat plates into rings, but the process is complicated, and it also damages the barrier film of the VIP itself, affecting the performance and life of the VIP. The current barrel-type insulation and box-type insulation are commonly used for multi-face splicing of flat VIP panels; the marginal effect of VIP panels of this structure is obvious, and the cold bridge at the splicing of VIP panels seriously affects the overall thermal insulation performance. Therefore, although the thermal conductivity of VIP is 2.5mW / m·k, the thermal insulation performance is about 7 to 9 times better than that of pure PU, but the thermal insulation performance in the actual box is only 2 to 3 times better than that of ...
