摘　　要：研究了以双酚A(BPA)为原料、NaBr-KBrO3作溴化剂合成四溴双酚A(TBA)的工艺条件,并研究了TBA及其与三聚氰胺、磷酰胺-Mg(OH)2复合对PE的阻燃性能.结果表明:TBA的最佳合成工艺为n(BPA)∶n(NaBr)∶n(KBrO3) = 3∶8.8∶4.4,室温反应5.5 h,回流反应2 h,得到淡黄色TBA,产率99.08%,熔点170～174℃;阻燃剂对PE的合适添加量分别为ω(TBA)=15%、ω(TBA-三聚氰胺)=15%、ω[TBA-磷酰胺-Mg(OH)2]=15%.The synthetic conditions of tetrabromobisphenol A(TBA) were studied using bisphenol A(BPA) as raw material,NaBr-KBrO_3 as bromination agent,and the fire retardance of TBA complexed with melamine,phosphoamide-Mg(OH)_2 were researched .Results showed that the synthetic optimum conditions were as follows:n(BPA)∶n(NaBr)∶n(KBrO_3)=3∶8.8∶4.4,reaction time 5.5 h at home temperature,reflux for 2 h ,the yield of product was 99.08%,m.p. 170~174℃. The suitable amounts of composite fire retardance were that TBA 15%,TBA-melamine 15%,TBA-phosphoamide-Mg(OH)_2 15% to polyethylene.
