The invention discloses a radome TPU protective film, which comprises a UV adhesive layer, a TPU composite layer and an antistatic polyurethane layer in order from bottom to top, and the TPU composite layer is covered with a TPU base layer, a first organic silicon composite layer from bottom to top in order layer, the second organosilicon compound layer and the third organosilicon compound layer, the first organosilicon compound layer includes organosilicon resin and aluminum silver paste and mica powder doped with organosilicon resin, the second organosilicon compound layer Including silicone-based resin and TiB 2 and TiC doped in the silicone-based resin, the third organosilicon composite layer includes silicone-modified acrylic resin and SiO 2 and TiO 2 doped in the silicone-modified acrylic resin. The protective film of the present invention is pasted on the surface of the radome, the UV adhesive layer has a strong degree of bonding with the radome, and is easy to replace without residue; the TPU composite layer has high corrosion resistance, repairability and antifouling performance; antistatic The polyurethane layer has electrical conductivity, which can avoid the accumulation of static electricity on the radome, so as to realize the comprehensive protection of the radome. |
