| 摘 要： | 通过不同偶联剂改性纳米氢氧化铝(ATH)及ATH/红磷复合体系填充阻燃PP,研究了表面改性剂的种类及用量和体系配比对体系阻燃性和力学性能的影响。结果显示:表面改性可有效提高ATH/PP体系的阻燃性和力学性能,硅烷偶联剂较油酸钠和钛酸酯改性效果更好;在PP体系中,其最佳添加用量为ATH质量的2%,体系中PP/ATH质量比为100:50时,改性可使体系氧指数提高14%～30.3%,垂直燃烧等级达FV-1级,且力学性能有较大提高。少量红磷加入可与纳米ATH形成协同阻燃,体系中PP,ATH与红磷质量配比为100:45:5时比单独ATH阻燃效果更好。

| Abstract: | Nano aluminum hydroxide (ATH) surface modified by different modifiers and ATH/red phosphorus composites were used for modifying PP as a flame retardant.The effects of the kind and mass of modifiers,the ratio of components on the flame-retardant and mechanical properties was studied.The results showed that the flame-retardant and mechanical properties of ATH/PP can be improved by surface modification;silane is better surface modifier than titanate and sodium oleate;the best mass ratio of silane is 2% of ATH'... |
