| Abstract: | The epoxy monomer 1,3,3’-tri-oxirane-2’-methoxy-benzophenone(DEBP)was synthesized with vanillic acid,m-diphenol,epichlorohydrin and so on as raw materials by simple two-step method.And DEBP was structurally characterized and determined via FT-IR,and was then mixed with 4,4'-diaminodiphenylsulfone(DDS),followed by heating and curing to obtain DEBP/DDS epoxy resin.For comparative purpose,commercially used diglycidyl ether of bisphenol A(DGEBA)was cured with the identical curing agent was used as a control.The results showed that DEBP monomer had higher curing activity than that of DGEBA monomer.The glass transition temperature of DEBP/DDS epoxy resin was 183℃,which was higher than that of DGEBA/DDS.The DEBP/DDS epoxy resin outperformed DGEBA/DDS epoxy resin in terms of flexural and tensile properties.The flexural modulus and strength of DEBP/DDS epoxy resin were measured as 2437.8 and 98.6 MPa and the tensile modulus and strength of DEBP/DDS were 2523.4 and 71.1 MPa.The cured DEBP/DDS also demonstrated excellent flame retardant property.The char residue at 800℃reached 35%,the limiting oxygen index(LOI)was 34%,the UL 94 level was V-0 and the total heat release was measured as 17.8 kJ/g.This research suggested that without indroducing any flame retardant element,an intrinsic flame-retarding epoxy resin was synthesized with bio materials. |
