Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
Referring to fig. 1, as an embodiment of the present invention, the present invention provides a UV tape including a substrate 110, a pressure sensitive adhesive layer 130, and an anti-reflection layer 120. The anti-reflection layer 120 is coated on one side of the substrate 110 with a first predetermined thickness. The pressure sensitive adhesive layer 130 is coated on the other side of the substrate 110 to a second predetermined thickness. The material of the substrate 110 is any one of PET, COP, and SRF. The material of antireflective layer 120 is siloxane.
In this embodiment, the pressure sensitive adhesive layer 130 with the second predetermined thickness can directly contact with the wafer or the filter, and has a strong adhesive force to the wafer or the filter, so that the position stability of the wafer or the filter is high. Meanwhile, the pressure sensitive adhesive layer 130 with the second preset thickness has a strong adhesive force to the release film 140, so that the release film 140 is closely attached to the substrate 110 to form a good protection for the pressure sensitive adhesive layer 130, and the possibility of spontaneous falling of the release film 140 is reduced. When the UV tape is in use, the anti-reflection layer 120, the base material 110, and the pressure-sensitive adhesive layer 130 are sequentially disposed from top to bottom. The base material 110 is any one of PET, COP and SRF, PO and PVC materials with 70% -90% of light transmittance and 40% -60% of haze are selected relatively, so that the light transmittance of the UV adhesive tape is greatly improved and the haze is greatly reduced by the base material 110. Here, COP (Cyclo Olefin Polymer) is a cycloolefin polymer and is commercially available from Raynaud corporation. SRF (super retro film) is a super-birefringent PET film available from Toyo (TOYOBO). The anti-reflection layer 120 with the first thickness can effectively improve the light transmittance of the UV tape, reduce the reflectivity of light, and increase the transmittance of light. Specifically, the material of antireflection layer 120 is siloxane. On the whole, the light transmittance of the UV adhesive tape is up to more than 96%, the haze is as low as less than 3%, the focusing difficulty of AOI optical automatic detection equipment during detection is reduced, the detection effect is improved, and the product yield is improved.
In an embodiment of the invention, the first predetermined thickness is 200-400nm, so that the transmittance of the UV tape is further improved. The second predetermined thickness is 10-30 μm, so that the manufacturing cost is reduced, and the working performance of the pressure sensitive adhesive layer 130 is ensured, so that the pressure sensitive adhesive layer 130 has better adhesion to the release film 140, the wafer or the optical filter.
In a specific embodiment of the present invention, the pressure sensitive adhesive layer 130 comprises the following raw materials in parts by weight:
20-60 parts of main resin, 10-40 parts of UV monomer, 0.5-10 parts of photoinitiator and 0.5-10 parts of cross-linking agent, wherein the total is 100 parts. Wherein the main resin is at least one of tackifying resins. Specifically, the main resin is at least one of tackifying resins such as polyacrylic acid, polyacrylate and polyurethane acrylate, the molecular weight is 10-60 ten thousand, and the TG value is-30 ℃ to-10 ℃. In some embodiments, the molecular weight of the host resin is 40-60 ten thousand, the TG value is-25-20 ℃, compared with the traditional host resin, the TG value is higher, the resin hardness is larger, the molecular weight is relatively higher, and the host resin can resist the high temperature generated by laser or cutter wheel cutting in the manufacturing process. Meanwhile, hydrophobic groups are grafted on the molecular branch chains of the main resin, so that the water-resistant resin has good water resistance. The UV monomer is at least one of polyurethane acrylate and aliphatic polyurethane acrylate, and the functional group of the UV monomer is 6 functional group or 8 functional group. The larger functional group is selected, so that the contraction degree of the pressure-sensitive adhesive layer is larger when the pressure-sensitive adhesive layer receives ultraviolet illumination, and the UV adhesive tape and the attached object are easy to separate. The absorption wavelength of the photoinitiator is 200-420nm, and the range of the wavelength capable of being absorbed is wide. Specifically, the photoinitiator is an acetone-based photoinitiator or other type of photoinitiator. The cross-linking agent is at least one of isocyanate cross-linking agent and epoxy cross-linking agent, and the cross-linking agent and the main resin can construct an isocyanate system or an epoxy system. Therefore, the cohesive force of the pressure-sensitive adhesive layer can be effectively improved, and the strength of the pressure-sensitive adhesive layer is enhanced. On the whole, the pressure sensitive adhesive layer 130 has good adhesion to the release film 140, the wafer or the optical filter, has good water resistance, is not easy to remain on a stuck object, has little pollution to the stuck object, has little influence on light transmittance, and is not easy to generate smoke when being cut.
In an embodiment of the invention, the UV tape further includes a release film 140, and the release film 140 is attached to a side of the pressure sensitive adhesive layer 130 away from the substrate 110, so as to protect the pressure sensitive adhesive layer 130 of the UV tape when the UV tape is idle. Specifically, the release film 140 is made of PET or PE.
