摘 要:利用新型含锌离子阻燃剂2-羧乙基苯基次膦酸乙二醇酯锌盐(CEPPA-Zn)合成阻燃聚酯,由于含金属离子的阻燃剂加入,聚合反应过程中,缩聚反应时间缩短,缩聚反应温度降低。利用差示扫描量热仪(DSC)测试阻燃聚酯的热性能,发现阻燃聚酯的玻璃化转变温度、结晶化温度及熔点均提高。热重测试(TGA)结果显示聚酯的热稳定性能提高,而且由于Zn离子的存在使得残炭量增加。极限氧指数(LOI)测试结果显示,当含Zn离子阻燃剂的质量分数达到7%时,阻燃聚酯的LOI值达到36.7%。The flame-retardant polyester was synthesized from TPA, EG and 2-carboxy ethyl phenyl phosphinic acid glycol ester zinc salt (CEPPA-Zn). Polycondensation reaction time is shortened and condensation polymerization temperature is reduced due to the presence of flame retardant agent. The thermal behaviors of the flame-retardant polyester were investigated by differential scanning calori- metry (DSC) and thermogravimetric analysis (TGA) , and it was found that flame retardant polyester's glass transition temperature, crystallization temperature and melting point were increased. TGA test showed that the thermal stability was enhanced, and the quantity of carbon residue was increased due to the presence of Zn ions. Limiting oxygen index (LOI) test showed that LOI value of the flame retardant polyester was up to 36.7% when the mass fraction of the Zn ions-containing flame retardant agent reached 7%.
