The performance of coolant is largely determined by corrosion inhibiter.By chemical composition, can be divided into inorganic type corrosion inhibiter and
Two kinds of organic type corrosion inhibiter.Inorganic type corrosion inhibiter mainly has nitrite/nitrate, chromate/bichromate, phosphate, silicon
Hydrochlorate, borate, molybdate, arsenical etc.；Organic inhibitor mainly has amine, aldehydes, alkynol class, organophosphor/vulcanization
Compound, carboxylic acid and its salt, sulfonic acid and its salt, heterocyclic compound etc..
By corrosion inhibiter to electrode process, corrosion inhibiter is divided into anode suppressive corrosion inhibiter, negative electrode suppressive corrosion inhibiter and mixing
The class of inhibition corrosion inhibiter three.Anodic corrosion inhibitor acts on anode metal, and the anion of corrosion inhibiter shifts to anode, increase anode pole
Change, be that corrosion potential is shuffled, so that anode metal is passivated, there is chromate, nitrite, silicate etc.；Cathode type corrosion inhibiter
Cathodic process can be slowed down, the overpotential that increase hydrogen separates out, be corrosion potential to negative movement, cation is shifted to cathode surface and may be used also
To form the precipitation diaphragm of chemistry or electrochemistry, there are Quadrafos, arsenic ion, antimony ion etc.；As its name suggests, mixed type inhibition
Agent plays inhibitory action simultaneously to negative electrode and anode, and corrosion current can be obviously reduced, the organic compounds category of mainly nitrogenous/sulphur.
If anodic corrosion inhibitor dosage is insufficient, abundant comprehensive diaphragm can not be formed in anode surface, be formed on the contrary
The corrosion cell of the big negative electrode of primary anode, accelerated corrosion.Cathode type corrosion inhibiter is that usage amount deficiency also will not accelerated corrosion.
By formed diaphragm, corrosion inhibiter is divided into type oxide film corrosion inhibiter, precipitation membranous type corrosion inhibiter, adsorbed film type corrosion inhibiter
Three classes.The direct or indirect oxidized metal of type oxide film corrosion inhibiter, layer of metal sull is formed, prevent corrosion reaction from entering
OK.This kind of corrosion inhibiter mainly for can passive metal in nonacidic solutions have good protection effect.
Precipitation membranous type corrosion inhibiter can form etch-proof precipitation membrane with the ionic reaction in medium and in metal surface, and it is thick
Degree is continuously increased with the reaction of corrosion inhibiter component present in medium and its corresponding co-precipitation ion, typically than thickness of oxidation film,
Easily cause fouling, compactness and adhesive force are also poorer than oxide-film, so the corrosion mitigating effect of this kind of corrosion inhibiter is not so good as type oxide film.
Polar group be present in adsorbed film type inhibitor molecular, metal surface can be changed in metal surface absorption film-forming
Property, and the hydrophobic grouping in molecule hinders water and depolarizing agent to reach metal surface, so as to realize inhibition.Film is very thin, but
Stability is slightly worse.
Boiling point, the viscosity ratio of ethylene glycol type engine coolant provided by the invention are more moderate, reduce the effect ratio of freezing point
Preferably.Appropriate inorganic salts and organic acid are added in the engine coolant, and inorganic salts are mainly blunt with metal reaction by itself
Change, generation passivating film reaches the protection to metal, and shortcoming is that depletion rate is fast.Organic acid mainly passes through the active table in metal
Face is adsorbed, and so as to change the electrochemical properties of metal surface, to prevent corrosion of metal, durability is strong, depletion rate ratio
It is slower.Ethylene glycol type engine coolant provided by the invention is by organic inhibitor, inorganic inhibitor, oxidized form corrosion inhibiter, heavy
Shallow lake type corrosion inhibiter combines use.The advantages of making full use of all types of corrosion inhibiter, it is aoxidized, precipitation, energy of adsorption inhibition mechanism
Comprehensive function is produced, preferably protection can not only be produced to metal, can also extend durability, keep long-acting protection.

Company。
In engine water-cooling system, it is a variety of that coolant will touch red copper, brass, steel, cast iron, cast aluminium, scolding tin simultaneously
Metal, various corrosion of metal behavior, absorption and passive behaviors also differ, and to realize the full protection of various metals just needs
Carry out the compounding of corrosion inhibiter.Metal corrosion mechanism in the system of different pH value is different, and the flow velocity of coolant, temperature etc. also can shadows
Ring the effect of corrosion inhibiter.
On the premise of effective inhibition is reached, inhibiter consumption is more few better, in the hope of reducing anti-corrosion cost.Most of inhibition
All there is optimal concentration in the use of agent, dosage is excessive or the very few performance for being all unfavorable for corrosion inhibition.For more metals, single group
Point corrosion mitigating effect it is unsatisfactory, it is necessary to carry out the compounding of corrosion inhibiter, and cooperative effect is existed only between some corrosion inhibiter, and
Its dosage realizes the problem of collaboration avoids antagonism from being one very complicated there is also optimal proportion.At present, the cooperation mechanism of corrosion inhibiter
Unclear, the present invention is molten using the compounding of specific cathode type and anodic corrosion inhibitor, the compounding of different adsorption groups, increase
Solve the compounding of dispersiveness, look after the compounding of different metal protection, obtain the formula of this ethylene glycol type engine coolant.
