摘要:

使用苯基膦酸将镁铝水滑石(LDHs)与正辛酰胺结合制备表面改性的镁铝水滑石(m⁃LDHs),研究了其对羽毛球场地用PVC地胶面层复合材料的热稳定性、力学性能、耐磨性能、阻燃性能的影响。结果表明,改性前后LDHs的晶体结构未发生明显变化;LDHs通过限制PVC分子链运动从而提高PVC的玻璃化转变温度(Tg)而由于内润滑作用m⁃LDHs的加入可大幅降低Tg;表面改性后的LDHs存在协效阻燃作用,能够有效抑制PVC的燃烧和分解从而表现出更优异的静态热稳定性和阻燃性能;当m⁃LDHs添加量为3 %(质量分数,下同)时,体系的力学性能基本达到了刚韧平衡且摩擦因数相比纯PVC降低了37.3 %;这一结果满足DB 13/T 2662—2018 PVC运动地胶安全规范规定指标的同时也为其作为羽毛球场地地胶面层材料的性能保留了弹力、强度、韧性及减震效果,可以有效减少运动时的肌肉疲劳和微损伤,使其能更好地应用于该领域;但是,过多的m⁃LDHs在PVC基体中仍出现团聚现象,从而导致其改性效果下降。

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.
