Book cover Handbook of Epoxy Blends

Abstract

The thermal properties of epoxy/rubber blends include glass transition, thermal conductivity, heat capacity, thermal expansion, and thermal stability and are systematically reviewed by a number of thermal analysis techniques including differential scanning calorimetry, thermogravimetric analysis, thermomechanical analysis, and dynamic mechanical analysis. The rubbers include usually used natural rubber, polybutadiene rubber, nitrile rubber, polyurethane rubber, silicon rubber, etc. Generally speaking, the addition of a rubber component to the epoxy resin will result in depression of glass transition temperature of it due to incomplete phase separation and incomplete curing reaction. It depends on the cross-linking density of the blends. The thermal conductivity of the blends is affected by the polar nature of rubber. The conductive rubber which is forming a continuous phase could enhance the thermal conductivity. Heat capacity of epoxy/rubber blends is affected not only by the polar nature of rubber but also the density of the formed blends. The thermal expansion behaviors are not only related to thermal and mechanical history but also depend on the network of modified epoxy resin. And further, the thermal stability of epoxy/rubber blends is mainly depending on the thermal stability of the rubber and the cross-linking density of the formed networks. The higher-heat-resistant rubber leads to higher thermal stability of epoxy/rubber blends.
