The invention discloses a cold bonding type PVDF wrapping tape for bridge cable protection and a preparation technology thereof.The wrapping tape comprises a fluorine-containing weather-proof film layer, an adhesive layer, a PET film layer, a high-performance sealing adhesive layer and an isolating film layer, the adhesive layer is arranged between the fluorine-containing weather-proof film layer and the PET film layer, the high-performance sealing adhesive layer is arranged between the PET film layer and the isolating film layer, and the performance of the wrapping tape is improved; the preparation process comprises the following steps: unwinding, gluing, drying, compounding, winding, unwinding, gluing, laminating and winding. The heat resistance of the wrapping tape is improved, the wrapping tape is high in bonding strength and more excellent in cold flow penetration and holding power, the fluorine-containing weather-proof film layer and the PET film layer are combined through the preparation process, the surface layer material has excellent aging resistance, corrosion resistance and barrier performance, and the surface layer material is not prone to deformation due to the fact that the butyl rubber layer is coated. The aging resistance, corrosion resistance and barrier property of the surface layer material are combined with the air tightness and water tightness of the high-performance sealant, the advantages of the two materials are fully exerted, and durability and waterproofness are achieved.
本发明公开了一种桥梁缆索防护用冷粘型PVDF缠包带及其制备工艺，缠包带包括含氟耐候膜层、胶层、PET膜层、高性能密封胶层和隔离膜层，胶层设于含氟耐候膜层和PET膜层之间，高性能密封胶层设于PET膜层和隔离膜层之间，提高缠包带的性能；其制备工艺包括：放卷、上胶、烘干、复合、收卷、放卷、涂胶、覆膜和收卷。本发明提高了缠包带的耐热性能，粘合强度高，冷流渗透，持粘性更优异，该制备工艺通过复合将含氟耐候膜层与PET膜层相结合，使面层材料具有优异的耐老化、耐腐蚀、阻隔性能，通过涂丁基胶层，将面层材料的耐老化、耐腐蚀、阻隔性能与高性能密封胶的气密性，水密性相结合，充分发挥两者的优势，做到耐久防水。
