摘要

以双酚A-双苯并(口恶)嗪(DBOZ)和9

10-二氢-9-氧杂-10-磷杂菲-10-氧化物 (DOPO)为原料

合成了双酚A-双DOPO(2DO)

再用其与苯胺、多聚甲醛反应

合成了含双DOPO的双酚A-双苯并(口恶)嗪(2DD).采用红外、核磁共振等分析手段对2DO和2DD的化学结构进行了表征

采用差示扫描量热仪对DBOZ和2DD的固化特性进行研究

使用热重分析仪分析了所得聚苯并(口恶)嗪的热稳定性.结果表明:在N2气氛中

含双DOPO的双酚A-双苯并(口恶)嗪热分解温度为353℃

在442℃分解速率达到最快

800℃时的残碳率为40.40%

300℃的质量变化为3.97%.与未引入DOPO的双酚A-双苯并(口恶)嗪树脂相比

其热分解温度提高了将近41℃

最大分解速率提高了将近70℃

残碳率提高了将近3.21%.

Abstract

The bisphenol A contained double DOPO (2DO) was synthesized by using double benzoxazine based on bisphenol A(DBOZ) and DOPO. And the double benzoxazine contained double DOPO based on bisphenol A (2DD) was synthesized by using 2DO

aniline and paraformaldehyde. FT-IR

NMR were used to characterize the chemical structure of 2DO and 2DD. Curing characteristics were studied with DSC and thermostability was studied with TG. In N2 atmosphere

initial decomposition temperature of 2DD was 353℃. At the temperature of 442℃

the fastest speed of decomposition was achieved. At the temperature of 800℃

carbon residue was 40.40%. Mass-change rate at the temperature of 300℃ was 3.97%. Compared with double benzoxazine based on bisphenol A

initial decomposition temperature increased by nearly 41℃

the fastest speed of decomposition increased by nearly 70℃ and carbon residue increased by nearly 3.21%.
