Preparation and performance study of anaerobic adhesives modified with vinyl-based POSS
This research used ethenyl-functionalized polyhedral oligomeric silsesquioxane(POSS-V)to modify the mechanical properties of anaerobic adhesive connectors to address the issue of their disas-sembly in the maintenance and repair of mechanical equipment.The study characterized the anaerobic adhesive before and after curing using infrared spectroscopy,and combined friction and wear tests,scanning electron microscopy analysis,rheological testing,torque testing,and shear strength testing to thoroughly investigate the impact mechanism of POSS-V on the performance of anaerobic adhesive.The research found that the introduction of POSS-V significantly improved the heat resistance of the anaerobic adhesive.Through cross-linking,the maximum destructive torque could be increased by 64.75%,and the cross-linking reaction between POSS-V and acrylic ester formed spherical particles,effectively reducing the friction coefficient.While increasing the destructive torque of the anaerobic adhesive,it also maintained or even reduced the disassembly torque value,thus optimizing the overall performance of the anaerobic adhesive.
