Abstract

The invention relates to the technical field of composite materials, and in particular relates to a material for preparing a radome and a preparation method thereof. The material for preparing the radome comprises polycarbonate, hollow glass beads and a methacrylic acid-butadiene-styrene terpolymer. The specific gravity of the composite material can be reduced by the hollow glass beads, and the dielectric constant and dielectric loss of the composite material are relatively small, so that the radome prepared from the material does not easily cause adverse effects on an antenna; moreover, when the material for preparing the radome is prepared, the hollow glass beads are fed from a side feeding cylinder, so that the breakage rate of the hollow glass beads can be reduced, and adverse effects on the specific gravity, dielectric constant and dielectric loss of the composite material due to breakage of the glass beads during extrusion granulation of a granulator are further avoided.
