一种尼龙树脂改性专用无卤阻燃增效功能母粒及其制备方法
摘要：
本发明涉及塑料改性加工技术领域，尤其是一种尼龙树脂改性专用无卤阻燃增效功能母粒及其制备方法；所述功能母粒以多重复合包覆二乙基次膦酸铝为磷系阻燃剂，所述功能母粒的质量百分比组成如下：多重复合包覆二乙基次膦酸铝55.0～65.0 wt.%、无水硼酸锌20.0～30.0 wt.%、尼龙6树脂8.0～10.0 wt.%、星形尼龙3.0～5.0 wt.%、苯乙烯–丙烯腈共聚物包覆聚四氟乙烯0.5～1.0 wt.%、分散剂0.5～1.0 wt.%、润滑剂0.3～0.5 wt.%；本发明所制备的功能母粒与传统阻燃功能母粒相比，显著提高了二乙基次膦酸铝的耐热性和热稳定性，使其适应尼龙树脂要求的高加工温度，从而更有效地提升了二乙基次膦酸铝对尼龙树脂的阻燃效果。
摘要（英）：

The invention relates to the technical field of modification and processing of plastics, in particular to special halogen-free flame-retardant synergistic masterbatch for modification of nylon resin and a preparation method of the halogen-free flame-retardant synergistic masterbatch. Multiple-compounded coated aluminum diethylphosphinate is adopted as a phosphorous-based flame retardant of the functional masterbatch, and the functional masterbatch comprises the compositions: in percent by mass, 55.0-65.0% of multiple-compounded coated aluminum diethylphosphinate, 20.0-30.0% of anhydrous zinc borate, 8.0-10.0% of nylon 6 resin, 3.0-5.0% of star-shaped nylon, 0.5-1.0% of styrene-acrylonitrile copolymer-coated polytetrafluoroethylene, 0.5-1.0% of a dispersant and 0.3-0.5% of a lubricant. Whenthe prepared functional masterbatch is compared with traditional flame-retardant functional masterbatch, the heat resistance and thermal stability of aluminum diethylphosphinate are improved significantly, aluminum diethylphosphinate is adaptive to a high processing temperature of nylon resin, so that the flame retardant effect of aluminum diethylphophinate on nylon resin is improved more effectively.
