Preparation and Curing Reaction Kinetics of Epoxy Resin Containing Biphenyl Structure/Montmorillonite Nanocomposites
摘要
Abstract
A new type of epoxy resin containing biphenyl structure/organo-montmorillonite nanocomposites was reported, which was based on 3, 3',5 ,5'-tetramethyl-diphenoldiglycidyl ether and O-MMT. The interlayer spacing of the O-MMT, corresponding to the d(001) plane peak was 2. 33 nm. The curing reaction kinetics of the TMBP/MMT system was studied by means of non-isothermal DSC. Based on the Kissinger method, the apparent activation energy (△E) was calculated to be 51. 25 kJ/mol. The reaction order (re =0. 88) was calculated according to Crane theory. The influences of the content of O-MMT on the intercalation and exfoliation structures of TMBP/DDM/MMT composites were investigated by wide X-ray diffraction (WXRD). The X-ray patterns reveal that only at the lower content of O-MMT, could the exfoliation nanocomposites be formed. The mechanical and thermal properties of the composites were measured. The results indicate that the composites have better mechanical properties and higher Tg than the pristine epoxy resin.关键词
