Abstract

The invention discloses a nanometer neodymium oxide lubricating oil additive, which is characterized by comprising nanometer neodymium oxide subjected to surface modification. A preparation method ofthe additive comprises the following steps of mixing Tween 60, Span 20, Span 80 and polyether according to a mass ratio of 2:1:1:3 to obtain a surfactant; then, adding 15 mass percent of the nanometerneodymium oxide into 85 mass percent of the mixed surfactant. The lubricating oil additive has the characteristics that the preparation method is simple; the energy conservation and environment protection are achieved; the abrasion reduction and good self restoration performance are realized.

Description

technical field [0001] The invention relates to a nano lubricating oil additive, in particular to a nano neodymium oxide lubricating oil additive. Background technique [0002] Lubricating oil is a commonly used lubricating material, which can reduce equipment wear, prolong equipment life and reduce maintenance costs. Lubricating oil is composed of different types of base oils and various additives with different properties. Among them, additives can make up for the lack of performance of base oils and are an important factor in improving the properties and quality of oil products. With the increasingly harsh working conditions of equipment and the strict requirements of environmental protection, traditional additives containing active elements such as S, P, and Cl can no longer meet the demand. Rare earth elements have a special 4f electronic structure, and their compounds have a hexagonal crystal layer structure. Compared with other metals with the same crystal structure,...
