一、绪 言 随着生产技术的发展,惯用的润滑油脂已不适应于某些工况,例如,在高负荷、低线速、真空、低温等条件下,油脂难以形成均匀的润滑膜;在腐蚀性介质或溶剂中,油脂常被破坏或溶解;在医药、食品、纺织、造纸生产中,油脂则是造成产品污染的主要原因。所以,具有自润滑特性的聚合物基复合材料,在无油脂润滑技术中显示了它的生命力。首先被研制和应用的是填充复合材料,即把粉末状、片屑状或短纤维状的填料加到聚合物基体中以 First, the introduction With the development of production technology, the conventional grease has not adapted to some conditions, for example, under conditions of high load, low linear velocity, vacuum, low temperature, grease is difficult to form a uniform lubricating film; corrosion In the medium or solvent, the oil is often destroyed or dissolved; In the pharmaceutical, food, textile, paper making, grease is the main cause of product contamination. Therefore, the self-lubricating polymer matrix composites show its vitality in grease-free lubrication technology. First developed and applied is the filling of composite materials by adding powdered, chip-like or short fibrous filler to the polymer matrix
