Problems solved by technology

Ordinary anti-wear agents use chemical film-forming technology, containing Teflon, aluminum, graphite, zinc and other metal components. The chemical protective film formed by it has poor high-temperature stability and is easy to fall off, which will directly aggravate the wear of the engine and block the oil circuit and oil. filter, causing the engine to go into overhaul prematurely
For example: the patent application for invention with the Chinese patent publication number CN1412283A discloses a kind of engine anti-wear additive, and the anti-wear additive contains organic metal salt; The compound contains phosphide; the invention patent application with Chinese patent publication number CN1403547A discloses a lubricating oil additive. Although these additives can reduce friction, due to the addition of sulfur, phosphorus, etc., long-term use will cause damage to mechanical equipment. certain corrosion

Abstract

The present invention discloses nanometer lubricating oil additive, a preparation method and an application. The additive consists of the following components according to the amounts by weight, namely, 0.5 to 5 parts of nanometer adamas, 0.8 to 10 parts of metal nanometer particles, 2 to 15 micro-emulsification surface active agent, 3 to 20 parts of micro-emulsification agent, 0.5 to 10 parts ofanti oxidant additive, and 8 to 20 parts of white oil. The nanometer lubricating oil additive of the present invention can be added into a variety of industrial lubricating oil, to lead the nanometerlubricating oil additive to have more outstanding operational performance, the friction can be obviously reduced, the corrosion of the machine is alleviated, the lubricating oil additive has the protective or reparative effect to the equipment or the parts and components, the service lives of the machine, equipment or the parts and components are effectively prolonged, and a great variety of difficult problems caused by friction and abrasion, the lubrication and the maintenance, or the servicing are solved. In addition, the nanometer lubricating oil additive of the present invention is even and transparent brown yellow liquid, thereby overcoming the defaults of nontransparency and instability, etc. existing in the tradition lubricating oil additive.

Description

technical field [0001] The invention relates to a lubricating oil additive, in particular to a nano-diamond and nano-metal composite lubricating oil additive and a preparation method thereof, belonging to the field of chemical industry. Background technique [0002] There are many existing lubricating oil additives, but most of them are traditional anti-extreme pressure additives containing organic metal salts, phosphorus, sulfur, etc. Pressure additives or anti-wear additives. Under extreme pressure conditions of lubricating oil or when the friction pair is in boundary lubrication, a layer of boundary film with properties different from that of the lubricating medium is formed on the metal surface, which effectively prevents direct contact between metals and reduces friction and wear. However, extreme pressure additives are generally compounds containing toxic molybdenum and chlorine). Ordinary anti-wear agents use chemical film-forming technology, containing Teflon, alumi...
