摘要
通过共聚法合成得到一种含有新型磷-氮阻燃剂Fyrol-6的阻燃聚酯,并通过改变反应温度、反应时间和催化剂用量,得到了优化的合成反应条件。在优化条件下,分别合成了阻燃剂添加量为对苯二甲酸双羟乙酯(BHET)质量的5%、10%、15%、20%的阻燃聚酯,对合成的阻燃聚酯进行了红外光谱(FTIR)、热失重(TG)和极限氧指数(LOI)测试。结果表明,合成的阻燃聚酯中含有BHET、Fyrol-6和OPA三种原料的结构特征;阻燃剂进入到聚酯分子链中后,其热稳定性提高,所制得的阻燃聚酯具有较高的LOI值,这种新型阻燃聚酯有望作为一种添加型阻燃剂应用于PET的阻燃改性。
The flame-retardant polyester containing the new phosphorus-nitrogen flame retardant Fyrol-6 was synthesized by copolymerization method, the optimized reaction conditions by changing the reaction temperature, reaction time and amount of catalyst was got. Under the optimized conditions, the flame retardant polyester, with the flame retardant quality content of 5%, 10%, 15%, 20% of the terephthalic acid bis-hydroxyethyl methacrylate （BHET） , were synthesized which were characterized by means of Fr-IR, TG and LOT. The results showed that the flame-retardant polyester contained the structure features of BHET, Fyrol-6 and OPA. After the flame retardant agent was added into the molecular chain of PE, the thermal stability was improved. The obtained flame retardant polyester had a higher LOI value. The new flame-retardant polyester WAs expected to be applied to PET retardant modified as an additive flame retardant.
