摘要
以苯酚、甲醛为原料,氢氧化钠(碳酸钠)为催化剂合成酚醛树脂,用硼酸锌改性使其成为具有耐高温性能、阻燃性能的硼酚醛树脂。通过热分析表明,有机硼改性酚醛树脂耐热性优于普通酚醛树脂;通过动力学分析表明,有机硼改性酚醛树脂主要热解阶段热解反应活化能高于普通酚醛树脂,难于反应。
Take the phenol, the formaldehyde as the raw material, the sodiumhydroxide (sodium carbonate) is the catalyst synthesis phenolics, with the zinc borate modification causes it to become has the thermostable performance, the being flarne-resistant performance the boronphenolics. Through the thermal analysis that, the organic boronmodified phenolics thermal stability surpasses the ordinary phenolics; Indicated through dynamics analysis that, the organic boron modifiedphenolics main thermal decomposition stage pyrolytic reaction activity energy is higher than the ordinary phenolics, difficulty withresponded.
