specific Embodiment approach 1
[0051] Specific Embodiment 1: In this embodiment, the hot embossing preparation method of Al-plated TPU film drag-reducing micro-grooves for airship skin is carried out according to the following steps:
[0052] 1. Use the ultra-precision micromachining machine tool system to process the Al template with a "V" groove structure on the surface. The "V" groove forms alternate transparent grooves on the surface of the Al template. Each groove The width s is 90-110 μm, and the depth h is 90-110 μm;
[0053] 2. Ultrasonic clean the Al template prepared in step 1 with acetone for 15-20 minutes, and after drying, apply three layers of film cleaning agent, then three layers of sealing agent, and finally three layers of water-based mold release agent , the coating time interval of each layer is 15-20min;
[0054] 3. Using vacuum evaporation technology, an aluminum film with a thickness of 90-110 μm is evaporated on the surface of the TPU film to be imprinted to obtain an Al-coated TPU ...
specific Embodiment approach 2
[0058] Embodiment 2: The difference between this embodiment and Embodiment 1 is that in step 1, the length of the template made of Al is 50-52 mm, the width is 50-52 mm, and the thickness is 5-8 mm. Others are the same as in the first embodiment.
specific Embodiment approach 3
[0059] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: in step 1, the width s of each groove is 95-105 μm, and the depth h is 95-105 μm. Others are the same as in the first or second embodiment.
