The effects of poly(styrene-ran-glycidyl methacrylate) on thermal, mechanical properties of epoxy resin for paint applications |
| 초록 |
Poly(styrene-ran-glycidyl methacrylate) (RCP) copolymer was synthesized as an additive via free radical polymerization for enhancement of flexibility of epoxy resin. The mixture of phenol novolac and triglycidyl p-amino phenol epoxy resins was cured with aliphatic amine hardener with various catalyst. The thermal and mechanical properties of RCP added epoxy resin were investigated by differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA), respectively. The crosslink density and glass transition temperature of epoxy resins was significantly increased due to the 3-functional epoxy in epoxy system. The tensile strain and contact angle of RCP contained epoxy system were gradually improved as a function of RCP content without any other reduction of tensile strength. The morphology of RCP filled epoxy resin was also analyzed by scanning electron microscope (SEM). |
