Problems solved by technology
The inventor believes that the use of rib structure in the vacuum heat insulation corrugated sandwich panel can improve the performance of the heat insulation panel. However, in the prior art, welding, gluing or bolting are often used to construct the rib structure. Both methods will bring a large workload to the production of vacuum insulation corrugated sandwich panels and increase the difficulty of production

Embodiment 1
[0052] In this embodiment, a vacuum heat insulation corrugated sandwich panel is provided, such as figure 1 As shown, the vacuum insulation corrugated sandwich panel has a shell and a core panel 3;
[0053] The core plate 3 is a corrugated plate; the cross section is a continuous corrugated structure with wave crests and wave troughs; adjacent wave crests and wave troughs form a repeating unit, forming a trapezoidal structure extension.
[0054] The shell is a hollow plate structure, consisting of two sealing plates 1 and four sealing edge strips 2;
[0055] The core plate 3 is fixed in the casing, and the two working surfaces of the core plate 3 are in contact with the two sealing plates 1 respectively; the sealing edge strips 2 are used to seal the cavity formed by the sealing plates;
[0056] A set distance is reserved between the end of the core board 3 and the inner wall of the shell, so that the cavity enclosed by the core board and the shell communicates with each othe...
Embodiment 2
[0061] In this embodiment, a vacuum thermal insulation corrugated sandwich panel is provided, and the vacuum thermal insulation corrugated sandwich panel is made of resin material.
[0062] The cavity between the core board 3 and the two sealing boards 1 is provided with a thermal insulation material; the thermal insulation material is a foamed polymer.
[0063] The sealing edge 2 is a gas barrier film. The rest of the settings are the same as in Example 1.
Embodiment 3
[0065] In this embodiment, a vacuum heat-insulation corrugated sandwich panel is provided, and the vacuum heat-insulation corrugated sandwich panel has a shell and a core panel 3;
[0066] The core board 3 is a corrugated board;

Abstract
The disclosure belongs to the field of vacuum heat-insulation composite materials, and in particular relates to a vacuum heat-insulation corrugated sandwich board. A vacuum heat-insulation material can realize excellent heat-insulation effects by relying on poor heat conduction effects in vacuum environment, and is widely used on refrigerated vehicles and outer walls of energy-saving environment-friendly buildings. A vacuum heat-insulation composite material usually needs to reach a certain thickness to achieve heat preservation effects, a vacuum heat-insulation corrugated sandwich board often adopts a lightweight material, and use strength is insufficient. In view of the above situation, the disclosure studies a stiffener structure of a composite board in order to improve heat-insulation performance and use strength of the vacuum composite board. The disclosure provides a vacuum composite board with a corrugated sandwich core, the core board with the structure has thermal conductivity of 0.03 w / mk or less, has good heat preservation effects, relatively high use strength and simple preparation method, and has good popularization significance.
Description
technical field [0001] The present disclosure belongs to the field of vacuum thermal insulation composite materials, and in particular relates to a vacuum thermal insulation corrugated sandwich panel with a corrugated core panel, a preparation method and application of the vacuum thermal insulation corrugated sandwich panel. Background technique [0002] The disclosure of information in this Background section is only for enhancement of understanding of the general background of the disclosure and should not necessarily be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art. [0003] The vacuum heat insulation technology reduces heat conduction and heat convection through high vacuum, and can achieve excellent heat insulation effect. Among them, the vacuum insulation corrugated sandwich panel is one of the vacuum insulation materials. The vacuum insulation corrugated sandwich p...
