技术领域 technical field
本发明涉及到一种自润滑材料及其制备方法，尤其是一种具有高孔隙度的多层复合自润滑材料及其制备方法。The invention relates to a self-lubricating material and a preparation method thereof, in particular to a multi-layer composite self-lubricating material with high porosity and a preparation method thereof.
背景技术 Background technique
压缩机工作时需要可靠稳定的润滑。当压缩机缺少润滑剂或润滑不合理时，压缩机内部就会产生严重异响，严重时还会造成压缩机部件的磨损失效。为保证压缩机运动部件的稳定性，需要对自润滑轴承表面进行切削或研磨加工，以防由于轴承磨损产生过大的间隙而导致压缩机产生过大的噪声。由于轴承主要是在边界润滑条件和缺油或少供油的条件下长时间运行，因而研制具有良好自润滑性能和长寿命稳定性的滑动轴承显得非常重要。The compressor needs reliable and stable lubrication when it is working. When the compressor lacks lubricant or the lubrication is unreasonable, serious abnormal noises will occur inside the compressor, and in severe cases, it will also cause wear and failure of compressor components. In order to ensure the stability of the moving parts of the compressor, it is necessary to cut or grind the surface of the self-lubricating bearing to prevent the compressor from generating excessive noise due to excessive clearance due to bearing wear. Since the bearing mainly operates for a long time under the condition of boundary lubrication and lack of oil or less oil supply, it is very important to develop sliding bearings with good self-lubricating performance and long-life stability.
美国达纳公司提出的中国发明专利(公开号CN1292852A，专利名称为“滑动轴承”)利用球形的铜合金粉，通过一定温度下烧结在覆铜钢板上，表面上烧结以聚四氟乙烯(PTFE)为主要树脂的高分子材料，通过卷制工艺制造轴承。此发明的缺点是由于孔隙率较小，在高载条件下表面聚合物改性层磨损后，虽然可以保持一段时间的稳定磨损期，但随着轴承的长时间运动，摩擦界面上露出的金属逐渐增多，导致轴承寿命急剧下降，并且易咬合对偶摩擦副。The Chinese invention patent (publication number CN1292852A, patent name "sliding bearing") proposed by Dana Corporation of the United States uses spherical copper alloy powder to be sintered on a copper-clad steel plate at a certain temperature, and is sintered with polytetrafluoroethylene (PTFE) on the surface. ) is the polymer material of the main resin, and the bearing is manufactured by the rolling process. The disadvantage of this invention is that due to the small porosity, after the surface polymer modified layer is worn under high load conditions, although it can maintain a stable wear period for a period of time, as the bearing moves for a long time, the exposed metal on the friction interface Gradually increasing, resulting in a sharp decline in bearing life, and easy to occlude the dual friction pair.
日本Taiho Kogyo Co.Ltd申请的美国专利(申请号为USP5217814，名称为“Sintered Sliding Material”)利用粒径为30～200μm的铜或铜合金粉烧结在钢板表面上，保证烧结的合金层孔隙率为5～70％，表面层烧结二硫化钼和铅粉等填充的聚四氟乙烯树脂，从而制备出滑动材料，可以显著提高材料的耐磨性。The U.S. patent (application number USP5217814, named "Sintered Sliding Material") applied by Japan's Taiho Kogyo Co. Ltd uses copper or copper alloy powder with a particle size of 30-200 μm to sinter on the surface of the steel plate to ensure the porosity of the sintered alloy layer The sliding material is prepared by sintering polytetrafluoroethylene resin filled with molybdenum disulfide and lead powder on the surface layer, which can significantly improve the wear resistance of the material.
日本Daido Metal公司申请的美国专利(申请号为USP5447774，名称为“Composite Sliding Member with High Porosity Sintering Layer”)将低表观密度的合金铜粉烧结在金属板材上，保证烧结后合金层的孔隙率达到50～80％，然后表面上覆盖以聚四氟乙烯为主要树脂的高分子改性层，通过烧结再轧制的工艺保证聚四氟乙烯树脂嵌入合金粉中，通过卷制制备自润滑轴承，可以有效地提高轴承的耐磨性。The U.S. patent (application number USP5447774, named "Composite Sliding Member with High Porosity Sintering Layer") applied by Japan's Daido Metal Company sinters alloy copper powder with low apparent density on the metal plate to ensure the porosity of the alloy layer after sintering It reaches 50-80%, and then the surface is covered with a polymer modified layer with polytetrafluoroethylene as the main resin. The sintering and rolling process ensures that the polytetrafluoroethylene resin is embedded in the alloy powder, and the self-lubricating bearing is prepared by rolling , can effectively improve the wear resistance of the bearing.
但上述这些发明的不足之处在于较高的孔隙率会导致金属合金粉与金属板的粘结性能下降，从而导致合金层的承载能力下降。同时，由于部分孔隙是闭孔，没有完全暴露在合金层的表面，导致表面聚合物无法渗入。另外，由于主要的润滑剂是以PTFE乳液为主体的糊状物，使得糊状物中的水分进入孔隙间，虽然水分在干燥后会蒸发，但具有粘弹性的聚合物材料并不易完全嵌入孔隙中，从而无法获得优异的自润滑性和耐磨性能，并且材料的机械性能呈下降趋势。However, the disadvantage of the above-mentioned inventions is that the higher porosity will lead to a decrease in the bonding performance between the metal alloy powder and the metal plate, thereby resulting in a decrease in the bearing capacity of the alloy layer. At the same time, because part of the pores are closed pores, they are not completely exposed on the surface of the alloy layer, so that the surface polymer cannot penetrate. In addition, since the main lubricant is a paste with PTFE emulsion as the main body, the water in the paste enters the pores. Although the water will evaporate after drying, the viscoelastic polymer material is not easy to completely embed in the pores. In this way, excellent self-lubricating and wear-resistant properties cannot be obtained, and the mechanical properties of the material show a downward trend.
