Description

A kind of extreme-pressure anti-wear composition for anti-ammonia turbine oil for being applicable chemical industry
Technical field
A kind of extreme-pressure anti-wear composition for anti-ammonia turbine oil for being applicable chemical industry of the present invention belongs to turbine lubricants Field.
Background technology
It is applicable in chemical industry synthesis ammonia and chemical industry heavy load steam turbine, compressor, except there should be special antioxygen Change outside stability, wear-resistant, extreme pressure, rust-preventing characteristic and resistance to emulsion, its most important feature is that to have anti-ammonia performance.Add due to using There is the additive formulations technology of special antirust agent, various soaps sediments can not be generated with ammonia reaction, so as to ensure equipment just Often operation.
Because ammonia is in the presence of having micro-moisture, mixture can be generated with the oxidation product in oil, be precipitated insoluble in oil, When steam turbine high speed heavy duty is operated, powerful centrifugal force can make to be thrown out of insoluble in the various precipitabilities in oil, adhere to Shaft coupling, makes shaft coupling dysequilibrium cause to produce vibration.
The content of the invention
It is an object of the invention to provide a kind of extreme-pressure anti-wear composition for anti-ammonia turbine oil for being applicable chemical industry, connect with ammonia Touch and chemical change generation soaps sediment do not occur, possess the performance such as good emulsion resistance, anti-bubble, froth breaking, anti-oxidant, it is adaptable to Large-scale Fertilizer Plant centrifugal syngas compressor, the lubrication of ice maker and Steam Turbine, cooling, flushing, antirust and sealing, can be protected Card machine is normally run.
The present invention adopts the following technical scheme that solution above-mentioned technical problem：
A kind of extreme-pressure anti-wear composition for anti-ammonia turbine oil for being applicable chemical industry, using the poly alpha olefin of mass ratio 80% SpectraSynTMPAO and 20% oil soluble polyether is compound to coordinate a variety of compound additives as fully synthetic composite foundation oil, Its each mass percent into being grouped into：
Component Mass percentage content

The mass percentage content of above each component is 100%.
Antioxidant is butyl/octyl diphenylamine T357 and 50% of mass ratio 50% complexing agent of derivative containing benzotriazole T532。
Metal deactivator is that the 1,4- dihydroxy anthraquinones and 20% mercaptobenzimidazole of mass ratio 80% are combined.
Antirust agent is the dinonyl naphthalene neobalgin T705A and 40% of mass ratio 60% alkenyl succinic acid half ester T747； Anti-foaming agent is No. 1 composite anti-foam agent.
Anti- emulsion is amine and epoxide condensation product T1001；Antioxidant preservative is 80% dialkyl dithio amino Formic acid esters and 20% molybdates esters.
Extreme pressure agent is oleic acid glycol ester T403C；Antiwear additive is the thio-ammonium phosphate T307 and 50% of mass ratio 50% D2EHDTPA phenyl ester T309.
Corrosion inhibiter is alkyl naphthalene sulfonic acid calcium.
The advantage of the invention is that：The present composition is contacted with ammonia, and chemical change generation soaps sediment, tool do not occur The performance such as standby good emulsion resistance, anti-bubble, froth breaking, anti-oxidant, it is adaptable to Large-scale Fertilizer Plant centrifugal syngas compressor, ice Lubrication, cooling, flushing, antirust and the sealing of machine and Steam Turbine, can guarantee that machine is normally run.
