摘要
为研究不同铝源对镁铝水滑石阻燃料阻燃性能的影响,利用常压下一步反应的液相法制备镁铝水滑石试样,采用XRD测试试样的相组成;用DTA-TG测试分析试样的热性能;结果表明:以Al2(CO3)3为铝源制备得的镁铝水滑石的晶粒比以NaAlO2为铝源制备得的镁铝水滑石的晶粒要小;以碳酸铝为铝源制备得的镁铝水滑石的第一次和第二次热分解温度范围比以铝酸钠为铝源制备得的水滑石热分解温度范围要宽;以碳酸铝为铝源制备得的镁铝水滑石阻燃料的氧指数,比以铝酸钠为铝源制备得的水滑石阻燃料的氧指数高。
Effect of aluminum resources on flame-retardant property of the Mg/Al-hydrotalcite flame-retardant materials is investigated. And Mg/Al-hydrotalcite samples are prepared by one step liquid reaction method at atmospheric pressure. Phase composition of the samples is tested by XRD. Thermal property of the samples is tested by DTA-TG. And the results show that the crystal size of Mg/Al-hydrotalcite, which (A) is made from Al_2(CO_3)_3 as the aluminum resource, is bigger than that of the sample, which (B) is made from NaAlO_2 as the aluminum resource. And the range of the thermal decomposition of the former is wider than that of the later. Meanuhile, the oxygen index of PE-EVA/(A) is higher than that of PE-EVA/(B).
