Description
Technical field
The present invention relates to a kind of nanometer additive field, particularly a kind of nano-diamond additive for lubricating oil and formula, production technique and application.
Background technology
Extreme pressure anti-wear additives mainly contains sulfur-bearing extreme pressure anti-wear additives, phosphorous extreme pressure anti-wear additives, chloride extreme pressure anti-wear additives, metal extreme pressure anti-wear additives.
Sulfur-bearing extreme pressure anti-wear additives kind is more, mainly includes alkene, sulfuration grease and thioesters, sulphur ortho ester, thiocarbonate, dithiocar-bamate and polysulfide etc.Wherein sulfide isobutene is the best kind of sulfur-bearing extreme pressure anti-wear additives.
China's sulfide isobutene throughput is 1500t/a, and product not only meets domestic needs, but also exports to foreign countries.China also develops 5 products (T324, T324A, T324B, T325 and T325A) such as many alkyl benzyl phenyl sulfide and polysulfide, and its sulphur content is 10% ~ 38%.
The phosphorous extreme pressure anti-wear additives of China has T304 (P), T305 (S/P/N), T306 (P), T307 (S/P/N), T308 (P/N) and T309 (P) six kinds, develop again boronation thio-ammonium phosphate (T301) in recent years, T301 is S/P/N/B agent, its outstanding advantage has better extreme pressure anti-wear, and it is one of ideal composition of preparation universal gear oil compounding agent.
Current chloride extreme pressure anti-wear additives principal item is clorafin and the chlorinated aliphatic acids of the multiple trade mark, and clorafin is active by force, extreme pressure anti-wear is good, is specially adapted to unmanageable metal, as the machining oil of Stainless Steel Alloy steel.But clorafin is under warm and hydrolysising condition, easily release chlorine atom, and then release HCl, cause the corrosion of iron.Clorafin has surrogate in recent years, but the price of surrogate is high, extreme pressure is active not too high, also be unable to do without clorafin to unmanageable metal.
Clorafin commodity thermostability, stability to hydrolysis and corrosion-inhibiting compared with same kind of products at abroad that China produces are poor.
The Typical Representative of metal extreme pressure anti-wear additives is lead naphthenate, zinc dialkyl dithiophosphate (ZDDP) and antimony, antimony dialkyl-dithiocarbamate borate and overbased sulfonate.
ZDDP is one of main additive of engine oil, is to have antioxygen, anti-corruption and wear-resistant multipurpose additive, has commodity selling both at home and abroad, is widely used in engine oil, antiwear hydraulic oil, industrial gear wet goods oil product.Because ZDDP can produce the ash content of the particulate matter in exhaust, and environmental regulation requires to be limited to particulate matter, and the application of ZDDP is restricted.
The extreme pressure property of dialkyl dithio antimony or carboxylamine antimony is better, is mainly used in, in industrial gear oil, having commodity selling both at home and abroad.
The extreme pressure anti-wear that borate extreme pressure anti-wear additives has had, thermal oxidation stability, the feature that burn into odorless is not nontoxic, but it is water-soluble, and should not use in the presence of water, purposes is restricted.There is commodity selling both at home and abroad.
High alkaline calcium sulfonate salt (sodium or calcium) extreme pressure anti-wear additives is immediate development, abroad existing commodity selling, and domestic carrying out is studied but have no commodity.It is mainly used in metal working oil, can be used alone, but extreme pressure anti-wear additives compound use that is normal and sulfur-bearing.It also has rust inhibition, and environmental protection can accept, and therefore can be used as the surrogate of clorafin.
