为了提高酚醛树脂（ PF）的耐热性能，采用硼酸、桐油、有机化蛭石对其进行了纳米改性、有机物改性和无机物改性相结合的复合改性。对改性树脂进行FTIR和热重分析。结果表明：采用硼酸、桐油改性PF后硼元素及桐油己经插入PF分子链中，使树脂的耐热性能得到提高，而添加适量的有机蛭石，明显提高PF的耐热性能和耐高温性能，其起始热分解温度比未改性树脂提高了40～50℃；复合改性的酚醛树脂能提高摩擦材料在高温下摩擦因数的稳定性，降低磨损率，能有效避免摩擦磨损性能的热衰退。

Nano modification,organic modification and inorganic modification were applied in integration to modify phe?nolic(PF)resin with boric acid,tung oil and organified vermiculite in order to improve its heat resistance performance.A?nalysis with FTIR and TG on modified resin was carried out.The results show that the boron element and tung oil are bond?ed to the molecular chain of PF after modification by boric acid and tung oil,which improves the heat resistance perform?ance of resin.The organified vermiculite can obviously improve the heat resistance and high temperature performances of PF,and the initial thermal decomposing temperature of PF is increased by 40~50℃ than regular phenolic resin.The com?pound modified PF resin can improve the stable friction coefficient of the friction materials under high temperature,reduce the wear rate,and can effectively avoid heat decay of friction and wear performance.
