Preparation and Properties of Anaerobic Adhesive Containing 2,3-Glycidyloxypropyl-POSS-Acrylate/Epoxy Acrylate

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 E_a 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.
