摘要：通过分子设计合成了含有酚羟基的3-甲基邻苯二酚/糠胺型苯并噁嗪(M-f).通过差示扫描量热法(DSC)测得M-f的放热峰值温度(Tp)为172℃,而间甲酚/糠胺型苯并噁嗪(MC-f)的Tp为244℃,表明酚羟基的引入有利于降低苯并噁嗪的开环固化温度.通过非等温DSC法研究2种苯并噁嗪单体的固化动力学,Kissinger法和Ozawa法的计算结果均表明M-f的表观活化能低于MC-f.此外,通过拉伸剪切强度测试考察了聚苯并噁嗪对于金属基材的黏附性能,M-f聚合物对于铝和低碳钢基材的拉伸剪切强度分别为2.53 MPa和3.09 MPa,均高于MC-f聚合物.
3-Methylcatechol/furfurylamine benzoxazine(M-f)containing phenolic hydroxyl group was synthesized to develop a benzoxazine that could be cured at relatively low temperature.The peak exothermic temperature(Tp)of M-f measured by differential scanning calorimetry(DSC)is 172℃,while the Tp of meta-cresol/furfurylamine benzoxazine(MC-f)is 244℃,indicating that the introduction of phenolic hydroxyl groups is beneficial to reduce the ring-opening curing temperature of benzoxazine.The curing kinetics of the two benzoxazine monomers were studied by non-isothermal DSC methods.The calculation results of Kissinger method and Ozawa method both indicated that the apparent activation energy of M-f was lower than that of MC-f.In addition,the adhesion performance of polybenzoxazine to metal substrate was explored by lap shear strength testing.The testing results demonstrated that the lap shear strengths of the M-f polymer to the aluminum and mild steel substrates reached 2.53 MPa and 3.09 MPa,respectively,which were higher than those of the MC-f polymer.
