N2 - In order to reduce the density of polyurethane resin materials in power, without losing its insulation performance, water absorption and heat resistance, three kinds of insulating glass beads were added to prepare polyurethane composites with different volume fractions. The properties of the composites were characterized by SEM, TGA, DSC and insulation resistance meter, and its density, insulation, water absorption and heat resistance were studied. The results show that the polyurethane composite with the 40% volume fraction of K20 glass bead has the best comprehensive properties, in particular, the insulating property is outstanding because the interface effect after the resin matrix and the glass beads with good insulating properties are combined to get the excellent insulation properties. The density of the best composite material is 0.737 g/cm3, the water absorption rate is 0.049%, the surface resistivity is 3.73×1015 Ω, the volume resistivity is 3.76×1015 Ω•cm, indicating that it can meet performance requirements of ultra high voltage composite insulators.
