摘要
采用一种无卤阻燃剂和自制抗滴落剂对丙纶进行改性试验研究。结果表明,阻燃剂的添加量为 0. 2%时,改性织物的极限氧指数 (LOI)即由改性前的17. 0%提高到26. 2%以上;当阻燃剂和抗滴落剂的添加量分别为0. 7%和 2%时改性效果最佳,改性丙纶的极限氧指数可达到 27. 6%,且无熔滴现象,同时具有良好的可纺性及物理性能。
Experimental research on modification of polypropylene fiber by using a kind of halogen-free retardant agent (NOP) and anti-dripping melt additives (MMP) as modifiers is carried out. The results show that, the limited oxygen index (LOI) of PP fiber can be raised from 17.0% to more than 26.2% when only 0.2% flame retardant agent is added. The optimal amount of addition of flame retardant and anti-dripping melt additives are 0.7% and 2% respectively and the LOI of the modified PP fiber can reach 27.6% with no occurrence of dripping melt, meantime the modified products have good mechanical properties and fit for spinning.
