Study on the Preparation and Performance of Epoxy Resin/AlOOH Nano-Composite Materials

Abstract

Using laboratory-made nano-scale r–AlOOH as nanophase raw material, the compounding method characterized by direct solution-blending was adopted to prepare epoxy resin/AlOOH nano-composite material; the influences of various factors, such as the dispersion characteristics of nano-scale AlOOH and its content in composite material, on mechanical and flame retardant properties of composite material were studied. The result indicated that the epoxy resin/AlOOH nano-composite material, compared with the ordinary Al(OH)3/epoxy resin composite material, possessed excellent mechanical and flame retardant properties. When the content of AlOOH was 10%, the tensile strength and the breaking elongation rate of composite material was increased by 189% and 468%, respectively. When the mass ratio of AlOOH/epoxy resin was 70/100, the impact strength was increased by 59%; after it decreased to about 60/100, the vertical combustion reached the level of V-0.
