摘要:
为了提高环氧树脂的阻燃性,本文以苯基膦酰二氯(PPD)、3-氨基-1,2,4-三氮唑(TA)为原料,四氢呋喃作溶剂合成了新型含磷阻燃固化剂PPDTA,通过红外光谱对该化合物结构进行了分析并确认。同时采用三因素三水平正交实验研究反应时间、反应温度、反应物摩尔比对产率的影响。结果表明,当反应时间10 h,反应温度70 ℃,TA与PPD摩尔比为2.2∶1时,在惰性气氛下PPDTA的产率可达到86.4%。将产物用于固化环氧树脂,通过极限氧指数(LOI)测试和垂直燃烧(UL-94)测试表征材料的阻燃性能,当环氧树脂体系中磷的质量分数达到2.5%时,LOI值达到32.7%,并通过V-0等级,证明材料阻燃性能良好。
Abstract:
To improve the flame retardancy of epoxy resin,we adopted phenylphosphonic dichloride (PPD) and 3-amino-1,2,4-triazole (TA) as the raw materials and tetrahydrofuran as the solvent and synthesized a new phosphorus-containing flame retardant curing agent PPDTA. The structure of the compound was confirmed by infrared spectroscopy. The effects of reaction time,reaction temperature and ratio of reactants on the yield were studied using three-factor three-level orthogonal experiment. The results show that the yield of PPDTA is 86.4% under the conditions of reaction time of 10 h, reaction temperature of 70 ℃ and the mole ratio of TA to PPD of 2.2∶1 in the inert atmosphere. The product was used to cure the epoxy. The flame retardant properties of the cured epoxy resin were characterized by limiting oxygen index(LOI) test and vertical combustion(UL-94) test. When the mass fraction of phosphorus in epoxy resin system is 2.5%, the LOI value reaches 32.7% and passes the V-0 grade. It is proved that the material has the good flame retardancy.
