Abstract

The invention relates to a nano-diamond lubricant additive as well as a formula, a production process and an application thereof. The invention provides the nano-diamond lubricant additive as well as the formula, the production process and the application thereof. The product of the invention is characterized in that the product appearance is white, the smell is nonirritant, the specific gravity is 1.25-1.30g / cm<3>, the viscosity index is 179-185, and the flash point is 288-290 DEG C. The preparation formula of the additive comprises the following components in parts by weight: 26-28 parts of a borate anti-wear reagent at extreme pressure, 27-29 parts of a silane coupling agent and 1.5-3 parts of a metal deactivator, wherein the borate anti-wear reagent at extreme pressure comprises pentadecyl calcium borate and hexadecyl calcium borate, and the silane coupling agent comprises hexadecyl trimethoxy silane and dodecyl trimethoxy silane. The production process comprises the following step: mixing and stirring the components to obtain the product, wherein the temperature during stirring is 75-85 DEG C and the stirring time is 14-16 minutes.

Description

technical field [0001] The invention relates to the field of nano additives, in particular to a nano diamond lubricating oil additive and its formula, production process and application. Background technique [0002] Extreme pressure antiwear agents mainly include sulfur-containing extreme pressure antiwear agents, phosphorus-containing extreme pressure antiwear agents, chlorine-containing extreme pressure antiwear agents, and metal extreme pressure antiwear agents. [0003] There are many varieties of sulfur-containing extreme pressure antiwear agents, mainly including alkenes, sulfurized oils and thioesters, sulfonate esters, thiocarbonates, dithiocarbamates and polysulfides. Among them, sulfurized isobutylene is the best type of sulfur-containing extreme pressure antiwear agent. [0004] The production capacity of sulfurized isobutylene in my country is 1500t / a, and the products not only meet domestic needs, but also are exported abroad. my country has also developed 5 ...
