本文报道以酚醛环氧树脂为主并加入适量的增韧剂及树脂改性剂形成的复合物作为粘结剂,和以二硫化钼为主要固体润滑剂且加入适量的稀土化合物及氧化锑等多种添加剂研制而成的PEP型润滑防锈两用干膜润滑剂。摩擦磨损试验结果表明,在给定的条件下,其摩擦系数为0.06～0.10,耐磨寿命比单用酚醛环氧树脂作粘结剂之干膜的提高近1倍,加入稀土化合物又使它的抗磨性能进一步提高;经100h5％NaCl溶液的盐雾试验和两年半时间的露天挂片耐候试验结果表明,喷涂PEP干膜的底材金属无锈蚀现象;这种干膜与法国SDA9干膜在Skoda试验机上的对比试验结果证明,其耐磨性能比后者的好。目前,PEP干膜已代替进口的SDA9干膜在塔式起重机及复印机一些部件上得到了成功的应用。
In this paper, the phenolic epoxy resin-based and adding an appropriate amount of toughening agent and resin modifier complex formed as a binder, and molybdenum disulfide as the main solid lubricant and adding the right amount of rare earth compounds and antimony oxide A variety of additives developed from the PEP-based rust and rust dual-use dry film lubricant. Friction and wear test results show that under given conditions, the friction coefficient of 0.06 ~ 0.10, wear life than single phenolic epoxy resin as a binder of the dry film to increase nearly 1 times, adding rare earth compounds and make it The results of salt weathering test of 100h5% NaCl solution and weathering test of two-and-a-half-day open coupon showed that there was no rust on the substrate metal of sprayed PEP dry film. The dry film was dry with French SDA9 The comparative test results of the film on Skoda testers show that the wear resistance is better than the latter. Currently, PEP dry film has been imported SDA9 dry film in the tower crane and copier some components have been successfully applied.
