Synthesis And Properties Of Epoxy Resin Of Bisphenol F And Bisphenol-f / A,

Factors affecting the property of Bisphenol F and Bisphenol F/A epoxy resin, such as BPF/ECH and BPF/BPA ration, temperature and time of etherify were studied. The finest synthetic progress of the Bisphenol F and Bisphenol F/A epoxy resin was decided by orthogonal methodes.The best curing craft of the BPA epoxy resin using TTA was studied too.The performances of the co-condensation and blend epoxy resin were test. IR investigation was used to analysis the main functional groups of those epoxy resin, X-ray diffraction was used to study crystallizing of those epoxy resin, SEM photo investigation was used to observe the feature of the flaw of those epoxy resin, GPC investigation was also used to study the average molecular weight and its distribution of those modified epoxy resin. At last, the curing reaction mechanism of the good performances modified epoxy resin was studied by thermal analysis, and the optimal curing process Parameterwas acquired.Comparing the performances of those cured the co-condensation and blendmodified epoxy resin shows that the viscosity of the all modified epoxy resines can be descent and theirs performances improved. Especially when the mole proportion of BPF/ (BPF+BPA) is 40%, viscosity of the co-condensation modified epoxy resin is 3. 2Pa. s.only 25% of the BPA epoxy resin' s at 25癈, the temperature of viterification is 112C, the point of intenerating is 88癈, the intension of drawing and bending is 82.5 and 171 MPa. when the weight proportion of BPFEP/BPAEP is 1:1, viscosity of the blend modified epoxy resin is 3. 3Pa. s at 25C, the intension of drawing and bending is 79.8 and 168.5 MPa.Accordingly, conclusion is that modification of the BPAEP using BPF or BPFEP is more better co-condensation than blend .
