摘要
利用亚麻油改性酚醛树脂（PF），得到高性能的摩阻材料用树脂基体．综合热分析结果显示改性PF在320～600℃间失重53．11％，普通PF失重73．51％；普通PF热分解峰为400～425℃和540～600℃，而亚麻油改性PF热分解峰为440～470℃和600～660℃，表明亚麻油改性PF的耐热性和热稳定性能均得到很大提高．推导了亚麻油的改性机理和改性PF的结构特征；发现亚麻油参与反应并成为聚合物结构的一部分，亚麻油改性PF固化后的结构特征是互穿聚合物网络（IPN）．
To obtain resin matrix of friction material with high-quality, linseed oil was used to modify phenolic resin. TG-DSC analysis shows that modified PF loses 53.11% weight between 320～600℃, while common PF loses 73.51% weight. The thermal-decomposed peaks of common PF are 400～425℃ and 540～600℃, while those for modified PF are 440～470℃ and 600～660℃, which means that the heat-resistance and heat-stability of linseed oil-modified PF is superior to pure phenolic resin. The modification mechanism and the structure characteristic were reckoned. The results show that linseed oil reacts with phenol and becomes a portion of PF structure, and the structure characteristic of modified resin after curing is INP.
