[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Embodiment 1:

[0019] A continuous release material-supported aerogel thermal insulation pad packaging structure, such as Figure 1 As shown, it includes a release material layer 1, and the release material layer is a release paper or a release film. A plurality of thermal insulation pad pasting units are arranged on the release material layer 1, and a spacing I4 is reserved between adjacent thermal insulation pad pasting units; the spacing I is based on the spacing between adjacent double-sided adhesive tapes, and each of the thermal insulation pad pasting units includes a double-sided adhesive tape 2 and an aerogel thermal insulation pad 3, and a spacing II5 is reserved between adjacent aerogel thermal insulation pads 3. The release material layer is continuous, and a plurality of aerogel thermal insulation pads are directly arranged on the release material layer to realize the overall packaging of a plurality of aerogel thermal insulation pads, which can be realized by automation and reduce the packaging cost.

[0020] Moreover, the release material layer of the thermal insulation pad pasting unit can be arranged in a zigzag stacking arrangement or in other arrangements. When the zigzag stacking is arranged in the packaging box, the spacing I is greater than the spacing II. The spacing I is the corner position of the stacking, and the spacing II is the distance between the double-sided adhesive tapes corresponding to the adjacent aerogel thermal insulation pads, such as Figure 1 As shown, the width of the aerogel insulation pad is fully considered when the spacing I and spacing II are reserved, and the width of adjacent aerogel insulation pads will not affect the folding and subsequent separation.

[0021] As for the correspondence between the double-sided tape and the aerogel insulation pad, the present embodiment adopts a one-to-one correspondence, that is, each aerogel insulation pad corresponds to a double-sided tape, and the contact area between the double-sided tape and the aerogel insulation pad is 25%-50% of the contact end surface area between the aerogel insulation pad and the double-sided tape. It is preferred to paste the double-sided tape at the center of the aerogel insulation pad, and the paste area ratio can have good viscosity while maintaining the mechanized equipment being able to be peeled off well. And the distance between the two double-sided tapes of the same insulation pad pasting unit is spacing II, and the distance between the two adjacent double-sided tapes of two adjacent insulation pad pasting units is spacing I. Because it needs to be folded, spacing I is relatively large to ensure overall folding.

[0022] Because the aerogel insulation pad will eventually be torn off for use, the 180° peeling force of the double-sided adhesive and release material layer is 15gf / 25mm-50gf / 25mm, which is suitable for aerogel insulation pad products of different weights.

[0023] Of course, the correspondence between the double-sided tape and the aerogel insulation pad can also be achieved by using the double-sided tape of the same insulation pad pasting unit as an integrated structure, the aerogel insulation pads are pasted on the double-sided tape at intervals, and the double-sided tapes between adjacent aerogel insulation pads are attached with an anti-sticking film.

[0024] During production, first adapt the release film or release paper to the peeling force of the double-sided tape, then cut the roll of double-sided tape into the required shape, and then adhere the double-sided tape to the continuous release paper or release film, and reserve spacing I and spacing II. Before attaching the aerogel insulation pad, it is necessary to match the double-sided tape with a carrier film to protect the adhesive surface. The carrier film used is generally a release film made of a polymer plastic material with a thickness of less than 50μm, and the release force between the double-sided tape and the double-sided tape is less than 3gf / 25mm, ensuring that the double-sided tape will not be reversed during use.

[0025] When the aerogel insulation pad is adhered, the carrier film is removed, and the spacing between the aerogel insulation pads is controlled by automated equipment according to spacing I and spacing II for precise positioning and pasting. After pasting is completed, press Figure 2 The zigzag stacking is carried out in the manner shown and stored in the packaging box 6, and then transported to the end customer in a centralized manner.

[0026] Embodiment 2:

[0027] A continuous release material-carrying aerogel thermal insulation pad packaging structure is provided, wherein a release material layer of a thermal insulation pad pasting unit is wound, with spacing I being equal to spacing II, and the structure is wound into a cylinder for placement and transportation, and the rest is the same as Example 1.

[0028] In the description of this specification, the description of reference terms such as "one embodiment", "example", "specific example", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
