dc.description.abstract | 1,4-Butanediol과 epichlorohydrin을 반응시켜 얻은 1,4-butanediol diglycidyl ether를 다시 acrylic acid와 반응시켜 광경화형 지방족 에폭시 아크릴레이트를 합성하였다. 이것을 3종류의 반응성 모노머(2-hydroxyethyl acrylate, tri(propylene glycol) diacrylate, trimethylolpropane triacrylate)로 희석하여 물성에 미치는 영향을 조사하였다. 점도는 희석 모노머함량의 증가에 따라 감소하였고 모노머의 관능기가 증가할수록 증가하였다. DMA를 이용하여 측정한 tanδ 피이크로부터 측정한 광경화필름의 유리전이온도는 모노머의 관능기가 증가할수록 고온으로 이동하였다. 광경화필름의 열안정성도 유사한 거동을 보였다. 광경화필름의 경도, 내마모성, 인장강도는 모노머의 관능기가 증가할수록 증가하였고 신장율은 모노머의 관능기가 증가할수록 감소하였다. 촉진내후성시험에서 황변 지수값이 모노머의 관능기가 많을수록 증가하였다. Photocurable aliphatic epoxy acrylate was prepared from acrylic acid and 1,4-butanediol diglycidyl ether that was obtained by reacting 1,4-butanediol with with epichlorohydrin. After the dilution with three kinds of reactive monomers (2-hydroxyethyl acrylate, tri(propylene glycol) diacrylate, trimethylolpropane triacrylate), the properties of photocurable aliphatic epoxy acrylate were investigated. Their viscosities decreased with the increased amount of reactive monomers, but increased when higher functionality of monomers were used. Glass transition temperature of UV-cured filn, obtained from tan peak of DMA (dimethylamine), shifted to higher temperatures as the functionality of monomer was increased, and thermal stability exhibited similar behavior. Hardness, abrasion resistance, and tensile strength of UV-cured film also increased with increased functionality of monomer, but elongation was reduced with the higher monomer functionality. In an accelerated weathering test, UV-cured film showed that the value of yellow index increased with increased functionality of monomer. | en_US |
