Abstract:

In this study, magnesium⁃aluminum layered double hydroxide (LDHs) was surface⁃modified by combining phenylphosphonic acid with octanamide to prepare modified LDHs (m⁃LDHs). The effects of m⁃LDHs on the thermal stability, mechanical properties, wear resistance, and flame retardancy of PVC composites for badminton court surface layers were systematically investigated. The results indicate that the crystal structure of LDHs remained largely unchanged after modification. While unmodified LDHs restricted the motion of PVC molecular chains, thereby increasing the glass transition temperature (Tg), the incorporation of m⁃LDHs significantly reduced due Tg to their internal lubrication effect. The surface⁃modified LDHs exhibited synergistic flame retardancy, effectively suppressing the combustion and decomposition of PVC, leading to enhanced static thermal stability and flame⁃retardant performance. At an optimal m⁃LDHs loading of 3 wt%, the composite achieved a stiffness⁃toughness balance in mechanical properties, with a 37.3 % reduction in friction coefficient compared to pure PVC. These results not only meet the safety specifications for polyvinyl chloride (PVC) sports flooring outlined in the Hebei Provincial Standard DB 13/T 2662—2018 but also preserve the elasticity, strength, toughness, and shock absorption required for badminton court surface materials. This effectively reduces muscle fatigue and micro⁃injuries during athletic activities, demonstrating significant potential for practical application in this field. However, excessive m⁃LDHs (>3 wt%) led to agglomeration within the PVC matrix, diminishing the modification effect.
