Abstract
The invention relates to an engine antifreezing solution which is prepared by mixing the following components to react: glycol, sodium molybdate, sodium hydroxide, isooctanoic acid, sebacic acid, sodium benzoate, benzotriazole, sodium 2-mercaptobenzothiazole, dye and deionized water. The invention adopts a new formula which uses organic matter as main component and inorganic matter as auxiliary component to reach the aim of controlled release on the basis of conventional inorganic and all-organic engine antifreezing solution technologies, wherein the organic acid uses the combination of monoacid and binary acid. The invention does not contain sodium borate and silicate so as to avoid the defect that precipitate is easy to generate due to the existence of sodium borate and silicate in glycol series antifreezing solution and the antifreezing solution is unstable; and the engine antifreezing solution of the invention does not contain amine, nitrate, phosphate and other substances which are harmful to the environment and human body. The researched antifreezing solution has good performances of stability, freeze-proofing, boil-proofing, corrosion-proofing and scale prevention through the cooperative interaction of components so as to perform multi-level anticorrosion protection for the cooling system of the vehicle.
Description
One, technical field
The present invention relates to a kind of low temperature resistant a kind of engine fluid that engine-cooling system is carried out comprehensive multilayer protection, belong to the chemical composition technical field.
Two, background technology
Engine fluid is the heat-eliminating medium of automobile water-cooling formula engine, can prevent effectively that cooling system fouling, metal parts from corroding, and makes normal working of engine.Good, the low price of present widely used engine fluid antiseptic property, but stability is bad.Mainly be that this deicing fluid has adopted silicate as sanitas, borax is as pH value buffer reagent, through after a while storage and use the back easily the formation gelatinous precipitate separate out, bad stability, corrosion inhibition is descended, and gel in use stops up engine pipeline and scatterer easily, reduces heat-transfer effect, causes cooling system failure.Simultaneously, do not wish to contain the material to environment and human body harmful such as amine, nitrate, phosphoric acid salt in the deicing fluid prescription, the use of conventional inorganic type deicing fluid is restricted.
In order to solve the problem of this respect, brought into use full organic engine deicing fluid abroad, and organic engine deicing fluid is owing to market cost height entirely, use is restricted, and its application only limits to a spot of high-grade car.
Three, summary of the invention
The purpose of this invention is to provide a kind of engine fluid, it is on the basis of conventional inorganic type and full organic engine deicing fluid technology, adopts based on organism, and inorganics is the new formulation of assisting, organic acid employing monoprotic acid and diprotic acid are compound, so that reach long-acting purpose.The present invention abandons easily forming inorganic materials silicate, the borax system of gelatinous precipitate, does not also adopt the material to environment and human body harmful such as amine, nitrate, phosphoric acid salt, the stable and environmental protection of the system that reaches.

" a kind of engine fluid " of the present invention prepared as follows:
Ethylene glycol with aequum adds in the reactor earlier, starts and stirs, and adds the benzotriazole of aequum under whipped state, fully stirring and dissolving.Deionized water with aequum slowly adds in the reactor under whipped state then, again Sodium orthomolybdate, Sodium Benzoate, hydrolytic polymaleic anhydride, 2-mercaptobenzothiazole sodium is added stirring and dissolving successively.Then sodium hydroxide, isocaprylic acid, certain herbaceous plants with big flowers diacid are counted in the reactor simultaneously, stirring and dissolving is transparent.Adjust pH to 8.5～10 with sodium hydroxide at last, add defoamer and dyestuff, through the strainer packing by 1 μ m after the assay was approved.
Mainly be described as follows at component of the present invention and characteristic:
1, Sodium orthomolybdate.Sodium molybdate solution can reduce the corrosion of ethylene glycol based antifreeze to cast aluminium alloy scatterer and cylinder cap, prevents aluminium pump cavitation corrosion.Benzotriazole that the present invention selects for use and Sodium orthomolybdate also have synergy, make the deicing fluid prescription can use the Sodium orthomolybdate of lower concentration effectively to reduce corrosion.
2, isocaprylic acid and certain herbaceous plants with big flowers diacid.Monoprotic acid isocaprylic acid of selecting for use and diprotic acid certain herbaceous plants with big flowers diacid have synergy when using together, can reduce cavitation erosion and the spot corrosion of ethylene glycol based antifreeze to metal, improve deicing fluid stability, increase the service life.
3, benzotriazole.The benzotriazole purposes is more, except scolding tin being had the special protection, red copper and brass is all had the certain protection effect.
4,2-mercaptobenzothiazole sodium.2-mercaptobenzothiazole sodium all has the certain protection effect to aluminium, copper and scolding tin, can effectively prevent the thermal etching of metallic surface.Especially when benzotriazole and 2-mercaptobenzothiazole sodium use together, produce good synergy, obvious to the preservative effect of copper and scolding tin material.
5, hydrolytic polymaleic anhydride.Hydrolytic polymaleic anhydride has the ability of metal ion such as calcium magnesium in the very strong treating water, and carbonate, phosphoric acid salt are had very strong restraining effect, can improve the stability of deicing fluid.
6, sodium hydroxide.Sodium hydroxide is used for regulating the pH value of deicing fluid, and the pH value of deicing fluid generally remains on about 7.5～11, can play corrosion-resisting function, preferably remains between 8.5～10.
7, not borax and silicate of the present invention, having avoided borax and silicate is easily to produce precipitation in the deicing fluid and make the unsettled shortcoming of deicing fluid at ethylene glycol, does not adopt the material to environment and human body harmful such as amine, nitrate, phosphoric acid salt.By the interaction between each component, but premium properties such as the deicing fluid of being prepared is had stable, antifreezely to boil, anti-corrosion anti-scale has carried out multi-level corrosionproof protection to automobile cooling system.
