AI Technical Summary

Technical Problem

Existing PVC printed decorative films are insufficient in terms of mechanical properties and environmental resistance. They are prone to tearing, aging, and corrosion, making them difficult to meet the decorative needs of complex indoor and outdoor scenarios.

Method used

Quaternary ammonium salt ionic liquids, epoxy-containing monomers, siloxanes, and composite fillers are used as modifying additives. Through precise proportioning and step-by-step modification, the molecular bonding force, flexibility, and physical strength of the membrane material are improved, forming a cross-linked structure and protective layer, thereby enhancing its tear resistance, UV resistance, and corrosion resistance.

Benefits of technology

It significantly improves the overall performance of PVC film, including tear resistance, UV resistance, hydrophobicity and corrosion resistance, extends service life, and is suitable for a variety of complex indoor and outdoor applications.

Abstract

This application discloses a tear-resistant PVC printed decorative film and its preparation method, relating to the technical field of PVC films. The film uses polyvinyl chloride as the base material, combined with basic additives such as plasticizers, cold-resistant agents, and heat stabilizers, and incorporates a modified additive made from quaternary ammonium salt ionic liquids, epoxy monomers, siloxanes, and composite fillers in a specific ratio. The modified additive is prepared through grafting, photocrosslinking, and composite dispersion steps, with each component acting synergistically and exhibiting good compatibility with the PVC base material. This preparation method not only improves the tensile strength and tear resistance of the PVC film but also endows it with excellent UV resistance, hydrophobicity, and resistance to media corrosion, solving the problems of poor mechanical properties and weak environmental tolerance of ordinary PVC decorative films. It is suitable for various indoor and outdoor decorative and protective scenarios, extending the service life of the film and reducing maintenance costs.
