Examples
preparation example 1）
[0022] See figure 1 and figure 2 , the aluminum-plastic composite tape of this preparation example is composed of an aluminum foil layer 1, an adhesive layer 2, and a plastic film layer 3. The adhesive layer 2 is located between the aluminum foil layer 1 and the plastic film layer 3, and bonds the aluminum foil layer 1 and the plastic film layer 3 together. The thickness of the aluminum foil layer 1 is 0.01-0.05 mm. The thickness of the plastic film layer 3 is 0.005-0.05 mm, and the plastic film layer 3 is a polyester tape layer. The adhesive layer 2 includes the following materials in parts by weight: 100 parts of epoxy resin, 6-15 parts of butylene phthalate or phospholipid diphenol ester, 2-5 parts of polyamide resin, silane coupling 2-5 parts of epoxy resin, 3-3 parts of epoxy curing agent, 1-3 parts of magnesium oxide, 2-5 parts of glycerin epoxy resin, 2-5 parts of aluminum oxide, and 3-8 parts of aluminum hydroxide. The adhesive layer 2 is continuously distributed ...

Embodiment 1）
[0027] See Figure 4 and Figure 5 , this embodiment is a system for manufacturing the aluminum-plastic composite tape described in Preparation Example 1 or Preparation Example 2. The system of this embodiment includes an aluminum foil layer release device, a plastic film layer discharge device, a composite tape forming device, a drying device, a composite tape traction device, and a composite tape winding device.
[0028] The plastic film layer 3 coiled on the raw material tray is released from the plastic film layer discharge device and enters the composite tape forming device and is maintained. The aluminum foil layer 1 coiled on the original plate is released from the aluminum foil layer discharge device and enters the composite tape forming device, and makes it above the plastic film layer 3 .
[0029] In the composite tape forming device, the adhesive layer 2 is coated between the aluminum foil layer 1 and the plastic film layer 3, and the initial composite tape is for...
