초록

액상고무 변성 에폭시(KR-207), 대두유 변성 에폭시(SWE-700), 지환식 에폭시(ERL-4221), 우레탄 변성 에폭시(UME-305)를 에폭시 수지(YD-128)에 대하여 각각 0 ~ 20 phr 혼합하고 혼합물에 대하여 여러 가지 물성을 시험하였다. 경화시간은 반응성 희석제의 양이 적을수록 경화온도가 높을수록 짧게 나타났다. 반응성 희석제의 종류에 따른 경화시간은 KR-207

The reactive diluents such as rubber-modified epoxy (KR-207), soybean oil-modified epoxy (SWE-700), cyclo-aliphatic epoxy (ERL-4221) and urethane-modified epoxy (UME-305) were mixed to the epoxy resin (YD-128) in 0 ~ 20 phr. Various physical properties were investigated for each of the mixtures. As less amount of reactive-diluent was used an cured the mixture at higher temperature, the shorter gel time was required. The order of gel time required for reactive diluent was UME-305 < ERL-4221 < SWE-700. When the reactive diluent was mixed up to 10 ~ 16 phr, the impact and adhesive strenghts were increased, but over that, the strengths gradually decreased. Mixing in KR-207 to the resin showed the highest impact strength, adhesive strength and solvent-resistance. Adding UME-305 to the resin represented the highest flexural strength at the filler-loaded state, however, mixing in ERL-4221 represented the highest flexural strength at the non-loaded state. Addition of ERL-4221 showed the highest flexural modulus.
