Background
Anaerobic adhesive is a single-component sealing adhesive prepared by utilizing the oxygen-free radical polymerization inhibition principle, can be used for bonding and sealing, and can be rapidly polymerized and cured at room temperature under the catalysis condition when an adhesive-coated surface is isolated from air.
The main performance index of the anaerobic adhesive is the curing speed, the faster curing speed can greatly shorten the time consumed in gluing, reduce the construction cost, most of the anaerobic adhesives in the current market are slower in curing speed and poorer in curing performance, greatly limit the application of the anaerobic adhesives, and although the curing speed can be improved by spraying a primer accelerator, the construction cost is increased, and the construction cost is greatly shortened. In addition, the strength after solidification directly influences the disassembly difficulty degree of the disassembly fastener after solidification, the disassembly easily causes the loosening of the fastener, and the disassembly difficulty causes great difficulty for later maintenance. For example, patent CN112175568A discloses a high-toughness high-strength anaerobic adhesive and a preparation method thereof, and specifically discloses that the main components of the anaerobic adhesive are polyurethane methacrylate and acrylate monomers, polytetrafluoroethylene is added to enhance the toughness and strength of the anaerobic adhesive, the curing positioning time is as short as 9min, but the shear strength is high, and the anaerobic adhesive is not easy to detach.
