제목 | The Characteristics of Complex Foaming Composites' Normal Pressure Foaming of Using Rubber and Environment-Friendly Materials |
초록 | There are many types of foam molding methods. The most commonly used methods are the pressure foaming method which foams resin mixed with a foaming agent at high temperature and high pressure and the normal pressure foaming method, which foams it at high temperature without pressure. The polymer resins used for foaming have their own viscosity. They need to be designed and analyzed for optimal foaming conditions of resins with low melt-viscosity or narrow optimal viscosity range for foaming under normal pressure. In this study, the characteristics of molded foam according to changes of viscosity, molding temperature, and cross-link foaming conditions were researched by blending rubber polymer with biodegradable resin. The properties according to cross-link/foaming viscosity were analyzed through a foam curemeter (FDR) and the optimal normal pressure foaming conditions according to torque were studied. Also, the correlation in foaming characteristics was studied through the analysis of tensile strength and elongation, which are mechanical properties of foaming composites. |
