Abstract
In order to prepare an anaerobic adhesive which has a good heat resistance, the epoxy acrylate of polyhedral oligomeric silsesquioxanes (POSSEA) -containing was synthesized and was used as a as main composition of adhesive monomers. The anaerobic adhesive was prepared from POSSEA, 2-hydroxyethylacrylate, acrylate, and selecting a suitable redox initiating system. The correlated properties were determined by DSC, TGA, so on. The results show that the appeared reaction order of curing reaction was 0.87 and activation energy Ea was 59.9 kJ/mol. The initial degradation temperature of this adhesive is 302 °C, and followed first order kinetics. The adhesive shear strength of steel plate is 24.6MPa. The results indicated that this anaerobic adhesive has well bonding strength and high temperature resistance property.
