摘要:采用季成四醇、三氯氧磷和间苯二酚为反应物,合成了新型添加型阻燃剂:间苯二酚-双[二(季成四醇)
磷酸(RBPP),通过元素分析、FIR和HNMR等测试技术表征了标题化合物的结构,结果表明,所合成的
标题化合物的结构与预期的结构一致。热失重分析结果证明,RBPP质量损失5%时的温度在350.0℃,600℃
残炭率高达57.4%,具有较高的热稳定性能。阻燃性能实验证明,E-51环氧树腊中添加质量分数为15.2%的RBPP
时,极限氧指数达31.8%,UL-94为V-0级。

Abstract: A novel phosphorus-containing flame retardant, resorcinol bis di(2,6,7-trioxa-l-phosphabicyclo
12. 2. 2j-octane-1-0x0-4-hydroxymethyl)] phosphate(RBPP) was synthesized from pentaerythritol
phosphorus oxychloride and resorcinol. The title compound was characterized by elemental analysis
FTIR, and H NMR. The results showed that the structure of the title compound was consistent with
expectation. Thermogravimetry ) investigation on thermal stability of RBPP showed that mass loss
of 5% was at about 350 C and residue at 600 C was as high as 57.4%. The limiting oxygen index
LO ) value coulds reach 31.8% and flame retardancy was UL-94 V-0 when mass fraction in E-51
epoxy resin was 15.2%
Key words: phosphorus-containing flame retardant; thermal stability; charring function; flame
