摘要
以硼酸和丙三醇为原料,采用含带水剂和不含带水剂两种体系合成了硼酸双甘酯(DGB),考察了n(C3H8O3)∶n(H3BO3)、反应时间、反应温度等因素对硼酸转化率的影响。以三氯氧磷和乙二醇为原料合成了二乙二醇基磷酰氯(DDYP)。采用交叉组合试验,研究了n(C3H8O3)∶n(H3BO3)、n(POCl3)∶n(C2H6O2)、n(DGB)∶n(DDYP)对DGB-DDYP阻燃效果的影响。结果表明,不含带水剂体系硼酸的转化率较高,DGB的优化合成工艺条件为:n(C3H8O3)∶n(H3BO3)=3∶1、反应时间4.0 h,反应温度120℃,硼酸转化率可达90.5%。DGB-DDYP的优化合成配比为:n(C3H8O3)∶n(H3BO3)=2∶1、n(POCl3)∶n(C2H6O2)=2∶1、n(DGB)∶n(DDYP)=1∶2,损毁炭长为11.5 cm。
Boric diglycerides (DGB) is prepared with boric acid and glycerol in water-carrying system and non water-carrying system respectively. The effects of n(C3H8O3): n(H3BO3), reaction time and reaction temperature on the boric acid conversion rate are studied. Diglycol phosphorus oxychloride (DDYP) is prepared with glycol and phosphorus oxychloride. The effects of n(C3H8O3) : n(H3B03), n(POCI3): n(C2H6O2) and n(DGB): n(DDYP) on the flame retardant efficiency of DGB-DDYP are studied by cross-over combina- tion experiment. The result indicates that the conversion rate of boric acid is higher in non water-carry- ing agent system. The optimum synthetic process conditions of DGB are: n(C3H8O3):n(H3BO3)=3:1, reaction at 120℃ for 4.0 h, the conversion rate of boric acid could reach 90.5%. The optimum synthetic proportion of DGB- DDYP is: n(C3H8O3): n(H3BO3) =2: 1, n(POCI3): n(C2H6O2) =2: 1, n(DGB) : n(DDYP) =l : 2, the damaged carbon length is 11.5 cm.
