A tungoil-phenol compound(TAP) and the tungoil modified phenolic epoxy resin(TMP) which were synthesized in the presence of acid catalyst, and the structure of these compounds were characterized by FTIR and GPC. FTIR analysis shows that the reaction between tungoil and phenol undermined the conjugate double bond of tungoil molecules, a new substitute product with phenol was formed. When the substitute product reacted with formaldehyde in the acid conditions and further reacted with epichlorohydrine, a tungoil modified phenolic epoxy resin(TMPE) was synthesized. The GPC analysis shows that resin is a mixture of tungoil modified epoxy resin and phenolic epoxy resin, and the molecular weight of tungoil modified phenolic epoxy resin and phenolic epoxy resin were 3 482 and 619 respectively.Solidification performance for the tungoil modified phenolic epoxy resins and E-44 epoxy resin at room temperature were investigated. The results show that when the mass ratio between tungoil modified phenolic epoxy resin and E-44 epoxy resin is at the range of 0.5 to 2.0, the higher tensile strength can be obtained.
