Description

Technical Field

[0001] This application relates to the field of mica composite materials technology, and in particular to one-time peelable tape and irregularly shaped mica parts produced using the tape. Background Technology

[0002] Irregularly shaped mica components are typically made by hot pressing multiple layers of mica paper using an irregularly shaped mold. Due to their excellent high-temperature resistance, electrical insulation, fire retardancy, and thermal insulation properties, they are widely used in electric vehicle battery packs, aircraft thermal insulation components, automotive engines, chemical equipment, and other fields. Irregularly shaped mica components are particularly suitable for electric vehicle battery packs, as they can improve the thermal runaway stability of electric vehicle battery packs.

[0003] Currently, irregularly shaped mica components used in electric vehicle battery packs are typically fixed using adhesives, thus requiring an adhesive coating process. Specifically, the irregularly shaped mica component includes a reference surface, which has recesses and protrusions. Double-sided adhesive is applied to the reference surface between the protrusions. In existing production lines, the adhesive coating process involves manually attaching multiple double-sided adhesive tapes to the designated reference surface of the irregularly shaped mica component.

[0004] In summary, the existing adhesive coating process for irregularly shaped mica parts is time-consuming and labor-intensive, which increases the overall production cost of these parts. To optimize the production cost of irregularly shaped mica parts, this application provides a one-time peelable adhesive tape and irregularly shaped mica parts produced using it. Utility Model Content

[0005] To address the time-consuming and labor-intensive adhesive coating process for irregularly shaped mica parts in existing technologies, this application provides a one-time peelable adhesive tape and irregularly shaped mica parts produced using it.

[0006] The disposable peelable tape provided in this application is achieved through the following technical solution:

[0007] A one-time peelable tape includes a release film and several adhesive strips. The release film includes a release film substrate and a silicone release agent layer laminated on the surface of the release film substrate. The adhesive strips are laminated on the silicone release agent layer of the release film. The release film has several sets of deformable holes.

[0008] The tape in this application can be peeled off in one go, which effectively improves the release paper peeling effect of irregular mica parts, thereby improving the overall production efficiency of irregular mica parts.

[0009] Preferably, a single group of deformable holes includes a plurality of deformable holes, wherein the deformable holes are elliptical holes, and the standard equation of the elliptical holes is (X... 2 / a 2 )+ (Y 2 / b 2)=1, a>b>0, a is 3 to 4 times b.

[0010] By adopting the above technical solution, the tearing of the release film can be avoided, which would affect the overall coating efficiency of irregularly shaped mica parts.

[0011] Preferably, the single group of deformable holes includes a plurality of deformable holes, and the spacing between adjacent deformable holes in the single group of deformable holes is equal.

[0012] More preferably, the release film is divided into an adhesive composite area and a non-adhesive composite area, and a plurality of deformable hole groups are formed in the non-adhesive composite area of ​​the release film. Each deformable hole group includes a plurality of deformable holes, and the deformable holes are evenly distributed in the non-adhesive composite area of ​​the release film.

[0013] By adopting the above technical solution, the stamping and cutting of release film is facilitated, and the production cost of release film is reduced.

[0014] Preferably, the thickness of the release film is 25µm, 40µm, or 50µm.

[0015] More preferably, the thickness of the release film is 25µm, 40µm, or 50µm.

[0016] Preferably, the release film is a PET film, a PE film, an OPP film, a PC film, a PS film, a PE film, or a TPX film.

[0017] More preferably, the release film is a PET film with a thickness of 40µm.

[0018] By adopting the above technical solution, it can be ensured that when the adhesive strip is applied to the adhesive strip pasting area of ​​the irregular mica part, the release paper will not break as a whole, thus facilitating the one-time peeling of the release paper.

[0019] The irregularly shaped mica parts produced using disposable peelable tape provided in this application are achieved through the following technical solution:

[0020] An irregularly shaped mica part produced using disposable peelable tape includes an irregularly shaped mica part substrate and a disposable peelable tape. The irregularly shaped mica part substrate has several protrusions and several grooves. The irregularly shaped mica part substrate has an adhesive strip pasting area. The adhesive strip in the disposable peelable tape is bonded to the adhesive strip pasting area of ​​the irregularly shaped mica part substrate.

[0021] By adopting the above technical solutions, the efficiency of overall adhesive coating of irregularly shaped mica parts can be improved.

[0022] In summary, this application has the following advantages:

[0023] 1. The one-time peelable tape in this application can be applied to irregularly shaped mica parts in one go, effectively improving the coating effect of irregularly shaped mica parts, thereby improving the overall production efficiency of irregularly shaped mica parts.

[0024] 2. The one-time peelable tape in this application can be applied to irregularly shaped mica parts in one go and the release paper can be removed in one go, which effectively improves the release paper peeling effect of irregularly shaped mica parts and thus improves the overall production efficiency of irregularly shaped mica parts.
