AI Technical Summary
Existing halogen-free flame retardants have poor compatibility with toughening agents in reinforced polyolefins, resulting in mediocre flame retardant performance, decreased mechanical properties, and insufficient resistance to damp heat aging, which affects the long-term stability and service life of the materials.
By using modified ammonium polyphosphate, maleic anhydride-grafted polyolefin elastomers, and polybutadiene, a multi-level structural design is formed through inorganic coating, active grafting, and the introduction of elastic segments to form a molecular interpenetrating network, which enhances interfacial adhesion and flame retardant effects and inhibits hydrolytic migration.
It improves the flame retardant and mechanical properties of reinforced plastics, enhances their resistance to damp heat aging, and ensures the stability and service life of materials in high humidity environments.
