UV硬化性 樹脂와 Alkyd樹脂 複合材料의 硬化擧動과 動的 粘彈性에 관한 연구
A Study on the dynamic viscoelasticity of UV curing polymer and alkyd resin composite materials UV경화성 수지와 Alkyd수지 복합재료의 경화거동과 동적 점탄성에 관한 연구
The ultraviolet(UV)-curable materials wildly have been used as a ink and coating materials. A according to measure UV polymerization phase separation of acryl groups 2,3,4-functional monomer, a few experiments were performed gel fraction, dynamic viscosity of alkyd resin blend system. Dependence of photoiniator concentration and various monomer, alkyd resin content investigated structural changes of films cured by UV irradiation. Curing rate measured UV irradiation under 25℃, cell gap 7cm and film thickness 100㎛. In results, it was through that the viscoelastic properties of films cured with increasing the ratios of monomer/alkydresin contents are network polymer in properties such as viscoelasticity.
