AI Technical Summary

Technical Problem

Traditional masterbatches suffer from insufficient toughness, uneven dispersion of nanofillers, low impact resistance, and limited processing performance, making it difficult to meet the application requirements of high-toughness materials and nanocomposite materials.

Method used

A high-toughness elastomer composite impact-resistant masterbatch was prepared by hybridizing nano-graphene oxide with eucommia gum and styrene-butadiene-styrene copolymer, combined with microencapsulated antioxidants and twin-screw extrusion molding technology. The uniform dispersion of nano-graphene oxide and the protection of microencapsulated anti-aging agents improve the toughness, impact resistance and processability of the material.

Benefits of technology

It significantly improves the toughness and impact resistance of the masterbatch, extends the shelf life of the anti-aging agent, ensures the long-term stability and processing performance of the masterbatch, and broadens its application areas.
