The vehicle engine fluid has the advantages of good corrosion effect, stable property, excellent corrosion inhibition property, no precipitate and no toxicity, and is not easy to volatilize, can be well absorbed on the surface of metal so as to form an absorption film, and can effectively inhibit corrosion of an antifreeze solution on soldering tin; and the selected additive is cheap and available and has good economic benefits and social benefits, and the like. The vehicle engine fluid can be widely applied to a cooling system of a vehicle engine, especially is used as a vehicle antifreeze solution in a low-temperature region.
Description
Technical field
The invention belongs to the deicing fluid technical field, be specifically related to the deicing fluid of car engine cooling system.
Background technology
Deicing fluid (being called cooling fluid, non-freezing solution again) is the heat-eliminating medium of engine cycle cooling system, has antifreeze, premium propertiess such as prevent boiling summer, annual anti-incrustation scale, protection against corrosion in winter.China starts from the seventies to the research of deicing fluid, product just occurs to the eighties, though development rapidly, but still with external like product obvious gap is arranged.Along with improving constantly of environmental consciousness and quality of life, people are to the demand cumulative year after year of environmental protection, safety freeze-proof liquid.In recent years, because the employing aluminum metal parts that engine system is more and more many, as aluminum cylinder, water pump, water tank, scatterer etc., even all-aluminium engine, therefore anxious deicing fluid to be solved is to the anticorrosion problem of aluminum metal, be badly in need of a kind of low temperature resistant, antirust, protection against corrosion of development, superior performance, moderate, particularly the protection against corrosion of aluminum metal parts had the environment protecting type engine deicing fluid of good economic benefit and social benefit.
Existing automobile engine winterization fluid, as number of patent application: 200910024033.9 " a kind of engine fluid " patent, disclosed deicing fluid is formed through stirring reaction by ethylene glycol, Sodium orthomolybdate, sodium hydroxide, isocaprylic acid, certain herbaceous plants with big flowers diacid, Sodium Benzoate, benzotriazole, 2-mercaptobenzothiazole sodium, hydrolytic polymaleic anhydride, dyestuff, defoamer, deionized water etc.The main drawback of this deicing fluid is: 1. Sodium orthomolybdate belongs to toxic compounds, can cause to a certain degree injury to human body, Europe has begun to limit the use of molybdate, can not contain molybdate as Volkswagen's deicing fluid standard code, and the deicing fluid of part type limits to its addition also; 2. Sodium orthomolybdate costs an arm and a leg, and its consumption is up to 0.3～0.05%, the cost height; 3. isocaprylic acid is a kind of organic compound frowzy, adds this material and can make deicing fluid that peculiar smell is arranged; 4. poor to aluminum metal parts corrosion-resisting function, can not satisfy the demand that Hyundai Motor develops.
Summary of the invention
The objective of the invention is weak point at existing automobile engine winterization fluid; a kind of automobile engine winterization fluid is provided, has low temperature resistant, antirust, protection against corrosion, superior performance, moderate cost, low toxicity, free from extraneous odour, the aluminum metal parts are had advantages such as excellent protective value.
The technical scheme that realizes the object of the invention is: a kind of automobile engine winterization fluid, and its component and mass percent thereof are as follows:
Deicing fluid of the present invention is 5 trades mark such as SH0521-99 standard-No. 25 ,-No. 30 ,-No. 35 ,-No. 40 ,-No. 45, can be applicable to envrionment temperature and be-20 ℃～-45 ℃ low temp area.
The preparation method of deicing fluid of the present invention: earlier with the component of automobile engine winterization fluid of the present invention, and, be positioned over again in the reactor, mix, again through obtaining product after the filter filtering and impurity removing matter by after its mass percent configuration.
After the present invention adopts above technical scheme, mainly contain following effect:
(1) replace Sodium orthomolybdate with sodium stannate, preservative effect is better and nontoxic.Sodium stannate belongs to anodic corrosion inhibitor, mainly is to form the difficulty soluble salt film of passive film or formation even compact by burning and in the metallic surface to reduce ethylene glycol based antifreeze to corrosion of metal.Especially when with the compound use of Sodium Benzoate, have good synergy, the spot corrosion of aluminium cylinder head under ferrous metal and the heat transfer state and aluminium radiator is all had excellent inhibition effect, and littler than other inhibiter consumption.
(2) stable performance, not volatile, nothing precipitates, free from extraneous odour.Sodium salicylate belongs to heat-resisting additive, can strengthen the thermostability of ethylene glycol based antifreeze, reduces its degradation speed, has the obvious suppression Degradation; Hydrolytic polymaleic anhydride belongs to water quality stabilizer, can effectively stop the formation of incrustation scale in the cooling water system, and better with the composite result of use of benzotriazole, has certain corrosion inhibition simultaneously; Do not contain materials frowzy such as isocaprylic acid in the deicing fluid, do not have peculiar smell.
(3) various metals in the cooling water car system all there is excellent Corrosion Protection, especially more outstanding to the protection of aluminum metal parts, can remedy the deficiency that has automobile antifreeze solution now, satisfy the demand of Hyundai Motor development.Mainly show: 1. the certain herbaceous plants with big flowers diacid is a kind of inhibiter that is applicable to deicing fluid system and excellent performance, when itself and benzotriazole are used, because certain herbaceous plants with big flowers diacid molecular volume is less relatively, insert easily in the slit after the ring compound benzotriazole adsorbs, make adsorption layer tightr, therefore corrosion of Carbon Steel is suppressed to have significant synergistic effect; When 2. certain herbaceous plants with big flowers diacid and hexanodioic acid are used, because the slit that long chain molecule certain herbaceous plants with big flowers diacid is adsorbed on behind the metallic surface can be remedied by the hexanodioic acid than small molecules, thereby can better suppress to corrode the particularly generation of local corrosion, protection to aluminium is particularly remarkable, certain herbaceous plants with big flowers diacid and hexanodioic acid are excellent pH buffer reagents simultaneously, progressively can better stablize its pH value in the acidifying process at the deicing fluid life-time service; 3. bi-imidazoline be a kind ofly have no irritating odor, Heat stability is good, inhibiter that toxicity is low, because it contains two nitrogenous five-rings, can better be adsorbed on the metallic surface and form adsorption film, therefore has excellent corrosion inhibition, when itself and 1-carboxyl-2-hexyl-5-(7-carboxylic acid group)-hexamethylene-can effectively suppress the corrosion of deicing fluid when 3-alkene is used to scolding tin.
(4) additive of selecting for use is less expensive, be easy to get, total additive capacity is less than 4.5%, cost is low, do not contain nitrite and the aminated compounds forbidden in the environmental regulation, do not contain and meet the phosphoric acid salt that hard water easily generates calcium, magnesium precipitate, also not containing the mordant traditional inhibiter borax of aluminium, is a kind of low toxic and environment-friendly type automobile engine winterization fluid that does not have amine, no boron, no nitrite, no chlorion, has good economic benefit and social benefit.
The present invention can be widely used in the cooling system of motor car engine, and particularly suitable is made the deicing fluid of the motor car engine of low temp area.
