▎ 摘 要
NOVELTY - The method for preparing cable filling material, involves (i) mixing 1,3-butadiene, styrene, peroxide, tetrahydrofuran, sulfur and n-hexane for contact reaction, adding graphene, carbonate, bentonite and nano zinc oxide to a system for foaming reaction, (ii) drying the system and molding to obtain cable filling material. USE - Method for preparing cable filling material (claimed). ADVANTAGE - The method enables simple preparation of cable filling material with excellent moisture resistance and easy available raw materials.
