Abstract
The invention discloses a special anti-freezing solution for an automobile engine, which comprises the following components in parts by weight: 1-2 parts of benzotriazole, 0.5-1 part of hydrolyzed polymaleic anhydride, 20-30 parts of calcium chloride, 10-12 parts of adipic acid, 1-3 parts of methyl tertiary butyl ether, 1-10 parts of citric colloid and 20-30 parts of deionized water. The added hydrolyzed polymaleic anhydride can form high-viscosity glue and solution, has the characteristics of adhesion, thickening, flowing, emulsion dispersion, forming, water retention, colloid protection, film forming, acid resistance, salt tolerance, suspension and the like, and is physiologically harmless. The anti-freezing solution provided by the invention has high viscosity (8-9Mpa.S), a good attachment effect and a freezing point below minus 48DEG C, and ensures the anti-freezing effect.
Description
Technical field
The present invention relates to a kind of deicing fluid, particularly relate to the special deicing fluid of a kind of motor car engine.
Background technology
The full name of deicing fluid should be anti-freeze cooling liquid, means the cooling fluid of antifreeze function.Deicing fluid can prevent the unfrozen cooling fluid when Cold Winter stops and spalling scatterer and freezing engine cylinder block or lid.But we will correct a misunderstanding, deicing fluid is not only winter, and it should use in the whole year.In automobile maintenance project normally, often travel 1 year, need engine fluid be changed.Railway and bulk granular goods easy freezing in car such as the coal of transport by road and breeze, gave transport and unloaded and bring great difficulty winter, caused great financial loss so not only to railway, harbour and coal consumers, also brought potential safety hazard simultaneously.The deicing fluid that current reality uses, often viscosity is on the low side, its viscosity number is usually at about 3MPaS, when spraying toward interior compartment side, stably can not be present in interior compartment side, cause in the process of spraying, thus produce the phenomenon of freezing car, both waste deicing fluid, had a strong impact on again antifreezing effect, cause the loss of goods.
Summary of the invention
for the deficiency that prior art exists, technical problem to be solved by this invention is, provides the special deicing fluid of motor car engine that a kind of production cost is low, good freezing protection effect, viscosity are larger.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of deicing fluid, is made up of the composition of following weight part:
Benzotriazole 1 ~ 2 part;
Hydrolytic polymaleic anhydride 0.5 ~ 1 part;
20 ~ 30 parts, calcium chloride;
Hexanodioic acid 10 ~ 12 parts;
Methyl tertiary butyl ether 1 ~ 3 part;
Citric acid 1 ~ 10 part;
Deionized water 20 ~ 30 parts.
The advantage of the special deicing fluid of motor car engine of the present invention is: the hydrolytic polymaleic anhydride of interpolation can form full-bodied colloid, solution, has adhesion, thickening, flowing, emulsion dispersion, figuration, water conservation, protective colloid, film forming, acidproof, salt tolerant, the characteristic such as to be suspended; and physiological harmlessness; deicing fluid viscosity of the present invention is high; viscosity number is 8-9MPaS; trailer is respond well; its freezing point, below-48 DEG C, ensure that antifreezing effect.
Embodiment
Below in conjunction with specific embodiment, the present invention is described in further details;
Embodiment 1:
The special deicing fluid of a kind of motor car engine, is made up of the composition of following weight part:
Benzotriazole 1 ~ 2 part;
Hydrolytic polymaleic anhydride 0.5 ~ 1 part;
20 ~ 30 parts, calcium chloride;
Hexanodioic acid 10 ~ 12 parts;
Methyl tertiary butyl ether 1 ~ 3 part;
Citric acid 1 ~ 10 part;
Deionized water 20 ~ 30 parts.
Certainly, above-mentioned explanation is not limitation of the present invention, and the present invention is also not limited to above-mentioned citing; those skilled in the art; in essential scope of the present invention, the change made, remodeling, interpolation or replacement, all should belong to protection scope of the present invention.
