利用氢氧化铝(ATH)、硅烷改性聚磷酸铵(APP)及APP/ATH复配阻燃剂与聚乳酸(PLA)、竹粉(BF)共混,制备阻燃型PLA/BF复合材料,并对其进行不同时间的浸水处理,测定阻燃型PLA/BF复合材料的吸水率和浸水处理前后的力学性能。结果表明,浸水处理后复合材料的拉伸强度和冲击强度均有不同幅度的降低,其中,APP/ ATH复配阻燃剂阻燃型复合材料力学性能下降最显著,浸水4 d后,其拉伸强度下降了近90 %;APP和ATH单独阻燃的复合材料在浸水过程中的吸水率和吸水厚度膨胀率均较低,而APP/ATH复配阻燃剂阻燃型PLA/BF复合材料的吸水率最高,尺寸稳定性最差。

Flame retardant poly(lactic acid)/bamboo flour composites were prepared with aluminium hydroxide(ATH),ammonium polyphosphate(APP),and APP/ATH blends as a flame retardant.Water absorption and mechanical properties of APP/ATH blends were tested after being soaked in water for various length of time.The tensile strength and impact strength properties of composites were decreased after being the soak treatment,in which the tensile strength decreased by nearly 90%after being soaked 4d.The blend containing either APP or ATH alone had low water absorption and thickness swelling rate,and those contain...
