蛤蜊壳粉在有机陶瓷型摩擦材料中的应用研究

摘要

Organic ceramic friction materials containing clam shells have been prepared using a phenolic resin as a matrix, magnesium oxide as a curing accelerator, wollastonite as a reinforcing fiber, clam shells, zircon, barite and potassium titanate as fillers, graphite as a solid lubricant and vermiculite as a noise reduction agent. The friction performance of the composites was tested by a Chase procedure and evaluated by an extension method. The results showed that clam shells can be employed in organic ceramic friction materials.%以酚醛树脂为基体,氧化镁为固化剂,针状硅灰石为纤维增强体,蛤蜊壳粉、锆英石、重晶石、钛酸钾片晶为填料,石墨为固体润滑剂,蛭石为降噪剂,设计了含蛤蜊壳粉的陶瓷型有机摩擦材料配方.用蔡斯(Chase)摩擦试验机测定了摩擦材料的摩擦性能,用可拓评价法分析了蛤蜊壳粉对摩擦系数和磨损率的影响.实验结果表明,蛤蜊壳粉可以在摩擦材料中应用.
