摘要：利用桐马酸酐为原料进行水解制得环氧固化交联性更高的桐油三酸(TOTA),再以不同物质的量比的9,10–二氢–9–氧–10–磷杂菲–10–氧化物(DOPO)和TOTA通过Michael加成反应制得TOTA–DOPO,红外光谱和核磁共振分析结果表明目标产物已成功合成;再将制得的阻燃固化剂TOTA–DOPO与E51环氧树脂(EP)固化后得到一系列刚性固化材料,并对其各项性能进行分析。研究结果表明,固化材料的拉伸强度随着DOPO加成反应量的增加逐渐降低,而其硬度、玻璃化转变温度、阻燃性能则随着DOPO加成反应量的增加逐渐增加;热重分析表明,制得的EP固化材料均具有良好的热稳定性,其热初始分解温度均在340℃以上。
Tung three acid（TOTA） possessing higher epoxy curing cross-linking performance was firstly synthesized using tong methyl maleic anhydride as raw material via hydrolyzation,and then TOTA–DOPO was synthesized by adding different molar ratios of 9,10-dihydro-9-oxa-10–phosphaphenanthren-10-oxide（DOPO） to TOTA via Michael addition reaction;FTIR and 1H–NMR analysis results showed that the target products were successfully synthesized;finally the E51 epoxy was cured by prepared retardant epoxy curing agent TOTA–DOPO and a series of rigid curing epoxy materials were obtained,and their comprehensive properties were studied. The results showed that the tensile strength of curing materials gradually decreased with the increase of DOPO reacted content,and the hardness,glass transition temperature and flame retardant performance gradually increased with the increase of DOPO reactant;thermogravimetric analysis showed that all the prepared cured epoxy materials owned good thermal stability,the heating initial decomposition temperatures were all above 340℃.
