This invention discloses a preparation method for a bio-based flame-retardant TPE cable material composition, belonging to the field of bio-based flame-retardant TPE cable material preparation technology. The bio-based flame-retardant TPE cable material composition comprises the following material components: MCA 22%, ADP 15%, PPO 6%, silicone masterbatch 2%-4%, titanium dioxide 1%, UV agent 1.1%-1.7%, bio-based synthetic oil 15%-20%, bio-based SEBS 15.7%-25.7%, bio-based polyolefin 7%-15%, and additives 1.2%. The preparation method comprises the following steps: S1, adding bio-based SEBS, bio-based polyolefin, and PPO into a high-speed mixer for thorough mixing to form a mixture; S2, adding additives and flame retardants during the mixture formation process to form a composition; S3, transferring the composition to a twin-screw extruder for melt extrusion granulation to obtain the bio-based flame-retardant TPE cable material. The bio-based flame-retardant TPE cable material composition prepared by this invention is made from partially bio-based raw materials, which is conducive to reducing carbon emissions and achieving sustainable development of polymer materials.
