description The new medium temperature curing adhesive film (SY-59) is prepared using core-shell particle as the toughening agent. The influence of core-shell particle toughening agent on the microstructure, glass transition temperature (Tg), bonding properties, and high-temperature resistance properties of the medium temperature curing adhesive films are studied. The results show that the tensile shear strength and the floating roller peel strength of the adhesive film improve significantly by adding the core-shell particle toughening agent. The SY-59 adhesive film exhibits characteristics of high strength and high toughness. The optimal content of the core-shell particle toughening agent is 15 phr, and the 23 ℃ tensile shear strength and the 23 ℃ floating roller peel strength of the corresponding adhesive film can reach 40.5 MPa and 10.6 kN·m-1 respectively. Meanwhile, compared with the carboxyl-terminated butadiene-acrylonitrile rubber (CTBN) toughening agents, the Tg of the medium temperature resin system modified core-shell particle toughening agents have no significant changes after being added to the medium temperature curing resin system. It indicates that core-shell particle toughening agents can effectively solve the problem of poor high-temperature resistance properties of rubber toughened medium temperature curing adhesive films, making the adhesive film with good high-temperatures resistance properties. The 120 ℃ and 150 ℃ tensile shear strength of the SY-59 adhesive film can reach 29.8 MPa and 10.2 MPa. Finally, the comprehensive properties of SY-59 adhesive film are evaluated, and the results show that the SY-59 adhesive film has excellent medium resistance properties, environmental resistance properties, batch stability properties and storage stability properties.
