Abstract
In order to determine the curing process of N,N-diglycidyl p-aminophenol glycidyl ether epoxy resin (AFG-90)/tetrahydrophthalic anhydride (THPA), curing reaction kinetics was studied by non-isothermal differential scanning calorimetry (DSC) method, and the solid buoyancy material with hollow glass microbeads (HGM) was prepared. Results show that the best ratio of AFG-90/THPA is 1:1. The apparent activation energy (E) and pre-exponential factor (lg A) obtained by Kissinger method are 67.72 kJ•mol-1 and 8.20 s-1, respectively. The most probable mechanism function of curing process can be described as Avrami-Erofeev equation. The curing process is 100 ℃, 1.0 h and 125 ℃, 2.5 h. The density and compressive strength of solid buoyancy material are 0.90 g•cm-3 and 113 MPa, respectively.
