氮气条件下酚醛的热分析

摘要酚醛树脂(PF)具有良好的耐酸性能、力学性能、耐热性能，广泛应用于防腐蚀工程、胶粘剂、阻燃材料、砂轮片制造等行业。由于酚醛具有苯环结构，所以尺寸稳定，变化率<1%。且化学成分稳定，防腐抗老化，特别是能耐有机溶液、强酸、弱碱腐蚀。安特福酚醛泡沫板在生产工艺发泡中不用氟利昂做发泡剂符合国际环保标准，且其分子结构中含有氢、氧、碳元素，高温分解时，溢出的气体无毒、无，对人体、环境均无害，符合国家绿色环保要求。故此，酚醛是最理想的防火、绝热、节能、美观的环保绿色保温材料。研究表明，不同升温速率下热重曲线形状相似，对DSC曲线的影响较明显；Ozawa法与Kissinger法所求得物质的动力学比较接近。60464

对酚醛的DSC、TGA实验结果进行比较全面的分析，获得热物性的基本特征。在材料可燃性多尺度研究中首先应采用微小尺度的热分析方法获得酚醛热解过程中的特征参数，本课题就是利用热分析方法在氮气环境中对酚醛进行实验研究。

Title thermal analysis of phenolic resin in nitrogen

Abstract

Thermosetting materials with good phenolic resin is not only a kind of fire characteristics. phenolic resin low thermal conductivity, good fireproof performance, easy construction, is the future direction of further development of external insulation materials. It is very worthy of study direction, at least in the property nature of the problem basically has no defect. phenolic resin not only low thermal conductivity, good thermal insulation properties, also has good thermal stability, flame retardant, low smoke, light, low toxicity, high mechanical strength, heat resistance, sound insulation, corrosion resistant ability, good corrosion resistance and other advantages. DSC,TGA results of phenolic resin comprehensive analysis, to obtain the basic characteristics of thermal properties. In the study of Material Flammability multi-scale should first thermal analysis method with small scale to obtain characteristic parameters of phenolic during pyrolysis, the subject is in a nitrogen environment for the experimental study of phenol-formaldehyde using the thermal analysis method.
