Description
Technical field
The present invention relates to a kind of metal antirusting agent for transformer and preparation method thereof.
Background technology
Metal in an atmosphere, can and oxygen, water and other impurity there is chemical action or electrochemical action under certain condition and produce metallic corrosion.Particularly be in the metallic substance between metalworking procedures, because surfactivity is high, workpiece in processing, carrying, checking, air, hand perspiration and contact with the obnoxious flavour in air through moisture, make workpiece be easy to produce corrosion, cause own processing work scrap or do over again.In order to prevent metal works corrosion between the shelf lives, antirust treatment must be carried out.Traditional antirust treatment has slushing oil process and water-based antirust agent process.
Slushing oil is made up of mineral oil, oil-soluble inhibitor and other additives; form protective oil film by slushing oil in metallic surface, isolated water in air vapour is to corrosion of metal, thus it is antirust to reach the long period; be characterized in simple to operate, there is certain rust-proof effect.But oiliness rust-preventive agent also has high volatile volatile, inflammableness, not easy-clear to need to consume a large amount of oil plant raw materials simultaneously, exacerbate energy consumption, the shortcomings such as waste resource, use oiliness rust-preventive agent also can pollute the Working environment of surrounding simultaneously, and in following process: such as weld, paint, electroplate, assemble and break seal, all need to clean oil removing, not only produce the discharge of a large amount of cleaning oily waste liquor, cause the pollution to environment, and cleaning oil removing is time-consuming, also can increase cost.
Traditional waterborne anti-rust process mainly uses Sodium Nitrite, dichromate and sodium carbonate, water glass etc. composite, be dissolved in the water composition waterborne anti-rust liquid under higher working concentration, be characterized in simple to operate, be applicable to short-term rust prevention between metalworking procedures, but it is short also to there is rust-proof life in this rust-proofing method, wherein main component Sodium Nitrite, dichromate are all highly toxic substances, cause huge harm to environment, operator.
Although also have developed several new water-based antirust agent both at home and abroad in recent years, compared with the requirement of water-based antirust agent, also there is a big difference with current antirust industry, and existing water-based antirust agent can not meet the needs in market.The stability of antirust time, rust protection liquid is all the leading indicator of par water-based antirust agent performance.
Rust preventing emulsion disclosed in Chinese patent CN1035522, by less than 10% polyvinyl alcohol, 1-20% oleic acid, the barium mahogany sulfonate of 2-18%, the trolamine of 1-35%, less than 10% paraffin, all the other are distilled water composition.Though have good rust-proof effect, paraffin is the most original membrane-forming agent, but because of film forming thicker, one is that enter down before one technique must membrane removal, and two is Parafilm membrane removal difficulties, time-consuming.Therefore the place being worth improving is still had.
Environment-friendlylong-life long-life emulsification rust-preventive agent disclosed in Chinese patent 201310066110, it consists of: white oil 40-50%; Oleic diethanola mide borate ester 20-30%; Sorbitan fatty acid ester 5-10%; Sodium dodecylbenzene sulfonate 5-10%; N-oleoyl flesh nitronic acid stearylamine salt 3-5%; Zinc naphthenate 3-5%; Polyoxyethylene nonylphenol ether 2-3%; Benzotriazole 0.5-1%; Water 5-10%.This formula has the following advantages: have good rustless property; This environment-friendly type aqueous rust-preventive agent 4-20 that adds water doubly uses, and still has good rustless property.In can be used for, long-term rust prevention; Meanwhile, easy to clean.Energy-saving and cost-reducing. decrease the harm to environment and workman.But cost of material is high, production cost is high, is unfavorable for applying.
A kind of composite membrane water-based antirust agent disclosed in Chinese patent CN201110119486, by composite to the organic zinc huge legendary turtle compound (5-15wt%) of synthesis, amide surfactants (5-10wt%) and rust inhibitor (0. 1-2wt%) obtained.Its preparation procedure is as follows: (1) adds organic zinc and intercalating agent after adding suitable quantity of water in a kettle., stirring at normal temperature 30 minutes; (2) acid amide of aequum or the derivative of acid amide is added in a kettle., stirring at normal temperature 20 minutes; (3) rust-inhibiting additive of aequum is added in a kettle., stirring at normal temperature 20 minutes; (4) add water to setting volume, continue stirring 20 minutes; (5) leave standstill 10 to 30 minutes, get rid of filling.Its using method is as follows: after described novel aqueous rust-preventive agent tap water being pressed 1:10-1:50 dilution, spray or dipping use; Described novel aqueous rust-preventive agent is added to metal working fluid, grinding fluid, clean-out system metal working fluid by 1:10-1:20 part by weight.
Although the composite membrane water-based antirust agent of this formula has the following advantages: replace slushing oil, fat to be used for sealing up for safekeeping of metal rust prevention during manufacture in intermetallic composite coating and finished product thereof antirust; As the rust-inhibiting additive of the metal working fluids such as metal working fluid, grinding fluid, clean-out system; Reduce the antirust cost in intermetallic composite coating, storage and transport process; In metallic surface without any residuals, keep metal true qualities, exempt cleaning process; Use rust-preventive agent time metal can be with water operate, use after without the need to dry, easy to use; For metal working fluid provides stable basicity, suppress the corruption of metal working fluid, go bad; Be applicable to the antirust of cast iron, steel and multiple steel alloy; Not containing hazardous and noxious substances such as nitrite, chromium, phosphorus, silicon, safety, environmental protection.But its preparation process is loaded down with trivial details, adds production cost.
