NOVELTY - The method for preparing rubber sheath with excellent thermal conductivity and charging characteristics, involves (i) mixing fluorosilicone rubber, butyl rubber, chlorosulfonated polyethylene, potassium titanate whisker, graphene, mica powder, talc powder, montmorillonite, acetyltributylcitrate and epoxidized soybean oil, stirring, adjusting the temperature, maintaining in vacuum to obtain the mixture, (ii) warming the mixture, resting, adding tert-butyl hydroperoxide, accelerator TMTM (tetramethylthiuram monosulfide) and antioxidant, thinning, and vulcanizing twice. USE - Method for preparing rubber sheath with excellent thermal conductivity and charging characteristics, for mobile phone. ADVANTAGE - The rubber sheath has excellent mechanical properties, avoids the damage caused by accidental drop of the mobile phone charging treasure, excellent heat dissipation effect and excellent heat resistance stability. The internal temperature of the charging treasure is effectively reduced, and the normal use of charging treasure is guaranteed.
