一种酚醛树脂/蛭石纳米复合基摩阻材料及其制备方法
摘要：
本发明涉及一种摩阻材料及其制备方法。一种酚醛树脂/蛭石纳米复合基摩阻材料，其特征是它是由酚醛树脂/蛭石纳米复合材料、碳纤维、钢纤维、硫酸钡、高岭土、二氧化硅、硅灰石、碳酸钙、石墨、二硫化钼、丁腈橡胶和六次甲基四胺原料制备而成，各原料所占质量份数为：酚醛树脂/蛭石纳米复合材料10～20，碳纤维1～5，钢纤维2～5，硫酸钡15～20，高岭土1～5，二氧化硅1～8，硅灰石1～15，碳酸钙1～15，石墨3～10，二硫化钼2～5，丁腈橡胶2～12，六次甲基四胺0.8～2。由于酚醛树脂/蛭石纳米复合材料具有热分解温度高、韧性好的优点，以该酚醛树脂/蛭石纳米复合材料作为粘结剂制备的摩阻材料具有耐热性能好、摩擦系数稳定、热衰退性小、磨损率低等优点。
摘要（英）：

The invention relates to friction material and a preparation process thereof. Phenol resin/vermiculite nano composite friction material is characterized in that the material is prepared by raw materials that phenol resin/vermiculite nano composite material, carbon fiber, steel fiber, barium sulfate, kaolin, silica dioxide, wollastonite, calcium carbonate, graphite, molybdenum disulphite, butadiene acrylonitrile rubber and hexamethylenetetramine, wherein of each raw material with parts by mass is: 10-20 phenol resin/vermiculite nano composite material, 1-5 carbon fiber, 2-5 steel fiber, 15-20 barium sulfate, 1-5 kaolin, 1-8 silica dioxide, 1-15 wollastonite, 1-15 calcium carbonate, 3-10 graphite, 2-5 molybdenum disulphite, 2-12 butadiene acrylonitrile rubber and 0.8-2 hexamethylenetetramine. Friction material which is prepared using phenol resin/vermiculite nano composite material as binding agent has the advantages of excellent heat resistance property, stable friction parameter, and small heat fading and low wear rate and the like, since the phenol resin/vermiculite nano composite material has the advantages of high heat decomposition temperature and excellent toughness.
