摘要: 为提升聚磷酸铵(ammonium polyphosphate, APP)在稻秸/HDPE(高密度聚乙烯)复合材料中的相容性,采用氨气冷等离子体对APP进行预处理,研究处理功率(100、200、300 W)和处理时间(1、2、3 min)对稻秸/HDPE复合材料阻燃性能和力学性能的影响。极限氧指数(limited oxygen index, LOI)测试结果表明,APP经过氨气冷等离子体预处理后,稻秸/HDPE复合材料的LOI均高于未处理试样; 当处理功率100 W、处理时间3 min时,LOI达到最大,为30.5%,较未处理时增加了10.9%。力学性能测试与双因素方差分析表明,氨气冷等离子体预处理APP对稻秸/HDPE复合材料的拉伸性能和冲击性能影响不显著,处理功率对稻秸/HDPE复合材料的弯曲强度影响显著。

Abstract: Pretreated by ammonia cold plasma, rice straw/high density polyethylene composites(RPC)with ammonium polyphosphate(APP)were prepared. The treatment power(100, 200 and 300 W)and time(1, 2 and 3 min)were carried out to investigate the effects on flame retard and mechanical properties of RPC. Results of limited oxygen index(LOI)showed that, RPC with APP pretreated by ammonia cold plasma exhibited higher LOI compared with the control sample. At a treatment power of 100 W for 3 min, the LOI of RPC with APP pretreated by ammonia cold plasma was 30.5%, increased by 10.9%. The results of the mechanical properties of RPC and two-way ANOVA analysis indicated that RPC with APP pretreated by ammonia cold plasma exerted no significant effect on the tensile properties and impact strength. The treatment power of ammonia cold plasma exerted a significant effect on the flexural strength of RPC.
