Description

Technical Field

[0001] The utility model relates to the technical field of cutting tapes, and specifically relates to a UV-reduced adhesion cutting tape. Background Technique

[0002] Cutting tapes are mainly applied in the manufacturing process of precision electronic components, such as the cutting and packaging of semiconductor wafers. In addition, it is also used for the processing and cutting of various tiny parts to ensure the stability and accuracy of the parts during the processing.

[0003] The disadvantages of existing cutting tapes mainly include the following aspects:

[0004] I. Environmental protection issues:

[0005] Many traditional cutting tapes use non-biodegradable materials, such as polyvinyl chloride (PVC), etc., which are difficult to handle after use.

[0006] II. Insufficient adhesion control:

[0007] Some cutting tapes may not be flexible enough in adhesion control and cannot be adjusted according to specific requirements.

[0008] III. Poor weather resistance:

[0009] The performance of some cutting tapes is easily affected under extreme environmental conditions (such as high temperature, low temperature, humidity, etc.), resulting in a decrease or failure of adhesion.

[0010] IV. Difficult to peel:

[0011] Traditional tapes may leave marks or residual glue when peeled, causing damage to the surface of the substrate.

[0012] V. Insufficient self-healing ability:

[0013] Most traditional cutting tapes do not have self-healing ability. Once the surface is damaged, only a new tape can be replaced.

[0014] VI. Poor antistatic performance:

[0015] The problem of static adsorption is relatively common in traditional tapes, and it is easy to adsorb dust and impurities. Content of the Utility Model

[0016] The purpose of the utility model is to provide a UV-reduced adhesion cutting tape to solve the problems raised in the above background technique.

[0017] To achieve the above object, the present utility model provides the following technical solution: A UV de-adhesive cutting tape, comprising a base layer, the base layer includes a PVC substrate layer, a temperature stabilizing layer is provided on one side of the PVC substrate layer, an enhanced adhesion layer is provided on one side of the temperature stabilizing layer, an adhesive layer is provided on one side of the enhanced adhesion layer, a UV-responsive layer is provided on one side of the adhesive layer, a customized UV-responsive speed layer is tightly bonded to one side of the UV-responsive layer, an antistatic layer is provided on one side of the customized UV-responsive speed layer, a protective layer is provided on one side of the antistatic layer, and a waterproof and breathable layer is provided on one side of the protective layer.

[0018] An easily peelable edge is provided at the edge of the base layer.

[0019] A nano-enhanced layer and a self-healing layer are embedded in the adhesive layer.

[0020] The PVC substrate layer, the temperature stabilizing layer, the enhanced adhesion layer, the adhesive layer, the UV-responsive layer, the antistatic layer, the protective layer, and the waterproof and breathable layer are tightly bonded by hot pressing or lamination.

[0021] Compared with the prior art, the beneficial effects of the present utility model are:

[0022] 1. Environmental protection: A biodegradable polyester film (such as PLA or PBAT) is used as the PVC substrate layer, reducing environmental pollution after use.

[0023] 2. Strong adhesion and weather resistance: The adhesive layer uses acrylic pressure-sensitive adhesive and is modified by adding nano-enhanced particles, improving the adhesion and weather resistance of the tape, enabling it to maintain a good sticking effect under various environmental conditions.

[0024] 3. UV-responsive de-adhesion: The UV-responsive layer uses a new type of UV-responsive polymer, which can reduce the viscosity under ultraviolet irradiation, facilitating the peeling and reuse of the tape, and improving the operational convenience.

[0025] 4. Customized UV-responsive speed: Through the customized UV-responsive speed layer, the UV-responsive speed of the tape can be adjusted according to actual needs, making it more flexible in different application scenarios.

[0026] 5. Antistatic function: The antistatic layer effectively prevents electrostatic adsorption, reducing the problem of the tape adsorbing dust or impurities due to static electricity during use.

[0027] 6. Temperature stability: The temperature stabilizing layer uses high-temperature resistant materials, ensuring the stability and service life of the tape in high-temperature environments.

[0028] 7. Self-healing ability: The self-healing layer is embedded with microcapsules containing a healing agent. When there are minor damages on the tape surface, it can automatically repair, extending the service life of the tape.

[0029] 8. Waterproof and breathable: The waterproof and breathable layer adopts a microporous waterproof and breathable membrane, which not only ensures the waterproof performance of the tape but also allows the surface under the tape to breathe, preventing the accumulation of water vapor.
