纳米亚微米矿物改性酚醛树脂及应用研究

以一定比例热稳定性好的纳米、亚微米矿物为载体，经机械力化学改性处理，制备成热塑性复合改性酚醛树脂，用作汽车摩擦材料的粘结剂。结果表明，由于改性树脂细度的提高，不仅改善了树脂在混合料中的分散性和混合均匀性，而且可提高树脂热分解温度，改善摩擦材料高温抗衰退性、降低磨损率，同时可减少树脂用量，降低摩擦材料生产成本。该研究对于高速制动材料的开发具有较大意义。

Study on Nanometer and Submicron Minerals-improved Phenolic Resin and Its Application

Improved thermoplastic compound phenolic resin was prepared with a certain proportion of nanometer and submicron minerals that had good thermal stability as the carrier and by mechano-chemical improvement, which was used as the binder of automobile-use friction material.The results indicated that the increased fineness of the improved resin could not only improve the dispersity and uniformity of the resin in the mixture, but could also raise the thermal decomposition temperature of the resin,improve the high temperature decaying resistance of the friction material and reduce the wear rate,the resin dosage and the production cost of the friction material.This study is of great importance to the development of high speed braking material.
