AI Technical Summary

Technical Problem

Existing cable protection pipe materials are insufficient in terms of flame retardancy, toughness, and weather resistance. They are particularly prone to aging and cracking in outdoor environments, and cannot meet the application requirements of special fields.

Method used

Organic-inorganic hybrid flame retardant materials were prepared using TiO2@NiCo-LDHs and phosphorus-doped polyaniline. The core-shell structure of the materials was formed by grafting poly(ethylene-octene) with thermoplastic acetic starch and maleic anhydride to improve their flame retardancy and toughness.

Benefits of technology

It improves the flame retardant and toughness of cable protection pipes, enhances their anti-aging and UV resistance, and extends the service life of the materials.
