Abstract

The invention provides a layered composite 3D vacuum insulated panel, which is provided with an accommodating cavity and an opening, and specifically comprises an inner barrier layer, a layered composite core material and an outer barrier layer, the inner barrier layer extends outwards along the opening at the opening position; and the outer barrier layer extends inwards in the opening direction and is compounded with the inner barrier layer on the extending surface. The layered composite core material is formed by stacking multiple layers of composite core materials, and the composite core material is formed by compounding a carrier layer, a powder layer and an anti-radiation layer. Compared with a common core material, the layered composite 3DVIP has the advantages that the 3DVIP thermalinsulation performance can be further enhanced, the thermal insulation time is prolonged, and the layered composite 3DVIP is more energy-saving and environment-friendly. The invention further provides a heat preservation container, and the layered composite 3DVIP is used in the heat preservation container.

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 ...
