A kind of rust-proof oil containing Tripolyglycerol monostearates
Technical field
The present invention relates to metal conditioner field, is exactly a kind of rust-proof oil containing Tripolyglycerol monostearates.
Background technology
Metal conditioner refers to the general name of chemical agent metallic surface being carried out to various process.Metal finishing includes oil removing, rust cleaning, phosphatization, the substrate pretreatment such as antirust, and for metal coating techniques, metal protection technology are prepared, the use of substrate pretreatment quality to after this coating preparation and metal has a great impact.
Oil-soluble antirust agent is also known as oil-soluble inhibitor.Great majority are for having the Long carbon chain organic compound of polar group.Polar group in its molecule relies on charge effect closely to adsorb on the metal surface; Non-polar group Long carbon chain hydrocarbon, then towards the outside of metallic surface, and together with dissolving each other with oils, thus makes rust-preventive agent molecular orientation be arranged in metallic surface, forms adsorptivity protective membrane, make metal not be subject to the erosion of water and oxygen.Can be divided into five classes by its polar group: 1. Sulfonates, chemical general formula is (R-SO3.Generally use basic metal or the alkaline-earth metal salt of mahogany acid, as barium mahogany sulfonate, petroleum sodium sulfonate, dinonyl naphthalene sulfonate barium etc.2. carboxylic acid and soap class thereof, chemical general formula is R-COOH and (R-COO) nMm.Carboxylic acid as rust-preventive agent has the lipid acid of vegetable and animals oils, as stearic acid, oleic acid etc., separately has the carboxylic acid that oxidized petrolatum, alkenyl succinic acid etc. synthesize, and also has petroleum products naphthenic acid etc.The polarity of the metallic soap of carboxylic acid is stronger than corresponding carboxylic acid, therefore rust-proof effect is better, but oil soluble is less.And chance water can be hydrolyzed, when disperseing in oil, stability is poor, sometimes separates out from oil.3. ester class, chemical general formula is RCOOR '.Lanolin, beeswax are natural ester compounds, are also good metal rust preventing sealing-up materials.The ester class rust-proof effect of polyvalent alcohol is fine, and such as single pentaerythritol oleate, sorbitan monooleate (Span-80), be all good metal antirusting agent, applies comparatively extensive.4. amine, chemical general formula is R-NH2, such as stearylamine etc.But the rust-proof effect of simple amine in mineral oil is good not, and conventional be the amine salt that generates of amine and organic acid or other mixtures, as oleic acid octadecylamine, stearic acid hexahydroaniline etc.5. sulphur, nitrogen heterocyclic, being sulfur-bearing or nitrogenous heterocycle and some derivative, is also good metal antirusting agent, the alkyl phosphate salt of such as tetrahydroglyoxaline, benzotriazole and alpha-mercapto benzothiazole etc.Imidazolines can be used for ferrous metal and non-ferrous metal is antirust, and it is antirust that benzotriazole etc. are then mainly used in the non-ferrous metals such as copper material.
Summary of the invention
