The invention discloses a preparation method of a high-impact multi-core data connection cable sheath compound, comprising the following steps: Step S1, weighing each raw material according to the following parts by weight: 80-100 parts of modified polyvinyl chloride resin, a 4-5 parts of base acrylate processing aids, 16-20 parts of calcium stearate, 12-15 parts of fillers, 8-10 parts of plasticizer, 1.2-1.5 parts of organotin stabilizer, 0.6-1 parts of antioxidant Step S2, premixing; Step S3, melt, extrude and granulate. The present invention obtains the modified PVC resin matrix with strong impact performance by adopting polybutyl acrylate copolymerization to modify the PVC resin; using the self-made plasticizer for blending and strengthening can not only increase the flexibility of the material, but also improve its impact resistance. In addition, it has synergistic flame retardant effect with Sb 2 O 3 in the filler. The obtained skin compound not only has high impact resistance, but also has good flame retardant performance. The wire plays a good protective role. |
