Abstract

The invention discloses a bionic nanometer self-organizing lubricating oil additive and making method, which comprises the following parts: 0. 5-5% self-organizing molecule, 0. 8-10% phase-transmitting catalyst, 2-15% micro-emulsifying surface-activator, 3-20% micro-emulsion adjuvant and 0. 5-10% boundary modifier. The invention widens the usage without any side effect, which solves kinds of difficulties due to friction, abrasion, lubricating culturing or maintaining.

Description

technical field [0001] The invention relates to lubricating oil additives, in particular to nano bionic self-organized lubricating oil additives and a preparation method thereof. Background technique [0002] At present, there are many lubricating oil additives published in patents, but most of them belong to the traditional anti-extreme pressure additives containing organic metal salts, phosphorus, sulfur and the like. Containing organic metal salts, such as Chinese patent application 02148328.0 discloses an engine anti-wear additive; containing phosphide, such as Chinese patent application 01130775.7 discloses an industrial gear oil additive composition, and Chinese patent application 01130774.9 discloses a lubricating oil Additives etc. Although these additives can play a role in reducing friction, due to the addition of sulfur, phosphorus, etc., long-term use will cause certain corrosion to mechanical equipment. [0003] As we all know, human joints transmit both load ...
