Description

Technical Field

[0001] The utility model belongs to the technical field of isolation films, and more specifically, particularly relates to an isolation film for high-temperature vacuum forming. Background Art

[0002] In the high-temperature vacuum forming process, an isolation film is needed. The isolation film is a microporous and porous film, mainly made of PP and PE, and mainly plays an isolation role. According to the material, the isolation film can be divided into: PET isolation film, FEP isolation film, PMP isolation film, PC isolation film, PMMA isolation film, etc. According to the function, the isolation film can be divided into: filling isolation film, protective isolation film, printed film, etc. The existing isolation film cannot withstand high temperatures, and cannot play a good isolation and protection effect when used. The structural strength and anti-corrosion effect are poor, and there is no protective reinforcement structure at the edge, which may cause cracks, and it is not convenient to cut and use.

[0003] Patent application number CN202022942284.X discloses an isolation film for high-temperature vacuum forming, including a winding drum and an isolation film body, both ends of the winding drum are fixed with protective side plates, the isolation film body is arranged on the outside of the winding drum, and the isolation film body includes a PET film layer, an antifouling coating, a PVC carbon fiber film layer, a polylactic acid film layer and a silicone rubber emulsion coating, an antifouling coating is arranged on the upper inner side of the PET film layer, and a PVC carbon fiber film layer is fixed on the lower side of the PET film layer, and a polylactic acid film layer is fixed on the lower side of the PVC carbon fiber film layer. The isolation film for high-temperature vacuum forming is provided with an isolation film body, the PET film layer has high temperature resistance, and has excellent physical properties, chemical properties, dimensional stability, transparency and recyclability, the PVC carbon fiber film layer can enhance the structural strength and main body thickness, and the polylactic acid film layer has good tensile strength and ductility, so that the isolation film body is not easy to tear.

[0004] When the above technical solution is actually used, the installation and disassembly between the mounting plate and the connecting plate and the protective side plate are achieved through locking bolts. Although the cutting mechanism can be reused to reduce the cost of use, the locking bolt body needs to be continuously rotated during the installation and disassembly process, which is more troublesome. If the locking bolt is tightened too much, auxiliary tools need to be used for disassembly, which greatly reduces the efficiency of installation and disassembly and is not convenient for rapid replacement of the take-up drum.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a high-temperature vacuum forming isolation film is provided, in order to achieve a more practical purpose. Utility Model Content
