This invention discloses a release film for multilayer ceramic capacitors and its preparation method in the field of polymer composite materials. The release film uses polyethylene terephthalate as the matrix, combined with a bimodal nanoparticle system composed of specific spherical silica and alumina. It innovatively introduces a bifunctional modifier containing perfluoroalkyl and siloxane groups, as well as a hyperbranched multi-arm block polyester siloxane synergistic interface modifier. The preparation process includes key steps such as nanoparticle surface modification, functional masterbatch melt blending and extrusion, and biaxial stretching molding. Through the synergistic effect of the two special modifiers, the dispersibility of nanoparticles in the matrix is ​​significantly improved, and the interfacial bonding strength is enhanced. This results in a release film with extremely low surface roughness and excellent anti-adhesion properties, while also exhibiting good heat resistance and dimensional stability, fully meeting the requirements of high-end multilayer ceramic capacitor manufacturing processes.

This utility model relates to the field of wire and cable technology and discloses a high-strength, tensile-resistant, and wear-resistant wire, including a wear-resistant sheath. Spherical protrusions are fixedly connected to the surface of the wear-resistant sheath, and reinforcing strips are fixedly connected to the inner cavity of the sheath. This utility model significantly improves the dynamic durability and resistance to mechanical damage of the wire through a multi-layer composite structure design. The three-layer composite sheath, combined with the surface spherical protrusions, forms a gradient wear-resistant system, improving wear resistance compared to traditional single-layer sheaths. Simultaneously, the aramid galvanized steel wire braided structure of the inner support layer and the anti-slip texture within the insulation layer's holes form a three-dimensional interlock, solving the problem of interlayer slippage caused by repeated bending. The multi-strand tinned copper wire strands in the conductor layer work synergistically with the reinforcing strips of the inner support layer, significantly increasing the wire's tensile strength at break and meeting the requirements of extreme working conditions. Furthermore, the precise engagement of the spiral protrusions and anti-slip textures effectively absorbs torsional stress, effectively improving the wire's service life.

This invention belongs to the field of unmanned aerial vehicle (UAV) technology and discloses an aerial docking mechanism for UAVs, comprising: a docking mechanism including a docking rod, wherein a wedge-shaped groove is formed at the connection between the upper and lower parts of the docking rod; and a take-up and take-down mechanism including a take-up and take-down housing, spring torsion plates, a torsion spring, and a rotating assembly. There are two spring torsion plates, symmetrically and horizontally installed within the take-up and take-down housing, with a central groove formed between the two spring torsion plates. The two outer sidewalls of the two spring torsion plates at their closest points are connected to the inner sidewalls of the take-up and take-down housing via the torsion springs; the two outer sidewalls of the two spring torsion plates at their furthest points are rotatably connected to the take-up and take-down housing via the rotating assembly. This invention enables two UAVs to dock in mid-air, achieving docking through the wedge-shaped groove of the docking rod and the UAV with the docking rod installed can also overcome the force of the spring torsion plates to separate, thus solving the problem of UAV docking in mid-air.
