In this study, polyurethane-acryl emulsion resins were synthesized from HDI (hexamethylene diisocyanate), IPDI (isophorone diisocyanate), Polyol, 2-HEMA (2-hydroxy ethylmethacrylate), n-BA (n-butyl acrylate) and MMA (methylmethacrylate). The effects of polyol types on the properties of polyurethane-acryl emulsion resin, such as degree of strength and water resistance and on the manufacturing process were investigated. In addition, the results were compared with those of acrylic emulsion. The test results showed that polyester type polyol demonstrated stronger tensile strength and higher water resistance with time than did acrylic emulsion and polyether type polyol.

본 연구에서는 HDI (hexamethylene diisocyanate)와 IPDI (isophorone diisocyanate), Polyol, 2-HEMA (2-hydroxy ethyl-methacrylate), n-BA (n-butyl acrylate) 그리고 MMA (methylmethacrylate)을 사용하여 폴리우레탄-아크릴 공중합 에멀젼 수지를 합성하였다. 또한 폴리올의 종류가 폴리우레탄-아크릴 에멀젼 수지의 제조 방법과 강도 및 내수성 등의 물성에 미치는 영향을 살펴 보았고 이를 아크릴 에멀젼 수지와 비교해 보았다. 실험 결과 폴리에스테르형 폴리올이 폴리에테르형 폴리올이나 아크릴 에멀젼보다 인장강도와 내수성 면에서 더 우수함을 보였다.
