AI Technical Summary

Technical Problem

Existing metal-plastic bonding technologies suffer from insufficient interfacial bonding strength, poor reliability, complex and costly processes, poor resistance to environmental aging, and insufficient versatility and multifunctionality, making it difficult to meet the needs of lightweight composite materials for widespread application in high-end fields.

Method used

Adhesive additives containing X, Y, and Z groups are used. The X groups form a dense hydrogen bond network, the Y groups generate Si-O-Me covalent bonds, and the Z groups decompose oil stains and form a nanoscale resin coating. Combined with modified nano-SiO2 and zinc borate coated particles, high strength, aging resistance and multi-material compatibility are achieved.

Benefits of technology

It improves the interfacial shear strength between metal and plastic, resolves the technical contradiction of the incompatibility between high strength and high efficiency, ensures that the plastic layer does not peel or flake during high temperature and bending processes, has self-healing properties, and is suitable for a variety of material combinations.
