The application discloses a PVD process high-temperature-resistant water-based coating adhesive protective film and a preparation method thereof. The protective film comprises a substrate layer, a water-based adhesive layer coated on one surface side of the substrate layer, and a water-based high-temperature-resistant coating layer coated on the other surface side of the substrate layer. The water-based adhesive layer is formed by coating and curing a first composition comprising a modified water-based acrylate emulsion, a high-temperature-resistant tackifying resin, a crosslinking agent, a first functional additive, and deionized water. The protective film is firmly attached without displacement, and the workpiece surface is free of adhesive residue after peeling. The VOC content of the fully water-based system is extremely low, meeting the requirements of green manufacturing.

This invention relates to the field of tape technology, specifically to an ultra-thin green PET pressure-sensitive adhesive tape with a high gyrometric coating reinforcement. The tape comprises a green PET substrate with a thickness ≤12μm and a primer reinforcement layer and a pressure-sensitive adhesive layer sequentially arranged therefrom. The primer reinforcement layer consists of an anchoring primer layer, an intermediate primer layer, a borate ester dynamic covalent pre-organized layer, an iron-citric acid slow-release coordination layer, a free trivalent iron locking layer, and a pH recovery and shaping layer. Through multi-layer synergistic action, it maintains high surface energy for a long time, significantly improving the interfacial bonding strength with water-based pressure-sensitive adhesives, resistance to damp heat aging, and resistance to die-cutting edge warping, while maintaining the flexibility of the substrate, making it suitable for the field of precision electronic assembly.

This invention relates to the field of adhesive preparation technology, and particularly to an environmentally friendly composite organic adhesive suitable for reinforcing and bonding multifunctional backpack components. The adhesive comprises 35% epoxy resin, 10% polyurethane, 35% ethyl cyanoacrylate, 10% liquid crystal polymer powder, 5% banana oil, and 5% acrylic acid. Synergistic effect of multiple components: epoxy resin provides high strength and rigidity, polyurethane provides flexibility and toughness, ethyl cyanoacrylate provides fast fixation, and liquid crystal polymer powder provides wear and weather resistance. The six components complement each other, achieving a combination of fast curing, high strength, flexibility, and weather resistance. Perfect compatibility with multiple materials: It exhibits excellent adhesion to fabrics such as nylon, polyester, and canvas, as well as ABS, PC, PP, TPU, and polyethylene fibers, with strong interfacial bonding and no selective adhesion defects. Extremely adaptable to various working conditions: It is resistant to repeated bending, friction and wear, water immersion, UV aging, and high and low temperatures, meeting the requirements of complex outdoor environments and long-term dynamic use, and the bonded parts are not prone to failure.
