一种环烷酸钙基二聚脲润滑脂及其制备方法
摘要：
本发明提供一种环烷酸钙基二聚脲润滑脂及其制备方法。以润滑脂重量为基准，该润滑脂包括以下组分：1）非牛顿体环烷酸钙10-70%；2）二聚脲0.5-30%；3）润滑基础油，10-80%。所述环烷酸钙基二聚脲润滑脂是将牛顿体环烷酸钙进行转化，并与二异氰酸酯、二胺和单胺进行反应得到的。本发明润滑脂具有优良的极压抗磨性和长润滑寿命，同时还具有优良的粘附性、抗水性、胶体安定性、高滴点、热安定性、防腐蚀性、抗盐雾性等性能。
摘要（英）：

The invention provides calcium naphthenate-based dipolyurea lubricating grease and a preparation method thereof. On a basis of the lubricating grease weight, the lubricating grease comprises the following components: 1) 10-70% of non-newtonian calcium naphthenate; 2) 0.5-30% of dipolyurea; 3) 10-80% of lubricating base oil. The calcium naphthenate-based dipolyurea lubricating grease is obtained by converting newtonian calcium naphthenate, and reacting with diisocyanate, diamine, and monamine. The lubricating grease of the invention has excellent extreme-pressure abrasion resistance and long lubricating life, and also has excellent adhesiveness, water resistance, colloid stability, high dropping point, thermal stability, corrosion resistance, salt mist resistance, and the like.
