Abstract
The invention relates to an engine coolant, in particular to the engine coolant with low solidifying point and corrosion resistance. The coolant is composed of following components: glycerol, distilled water, sodium phosphate, phosphoric acid, sodium nitrate, sodium silicate and benzotriazole/borax. The inventive coolant has good corrosion resistance to steel, copper as well as aluminum.
Description
Technical field
The present invention relates to a kind of engine coolant, the cooling liquid for engine of particularly a kind of low-freezing, erosion resistance.
Background technology
Engine coolant is as one of cold district essential product in winter, and it is low to require it to possess zero pour, and metal is not produced corrosive nature.Conventional cooling fluid is maximum with ethylene glycol-water type, the zero pour that this class cooling fluid reduces as pour point depressant with ethylene glycol, thereby reach non-icing requirement, but the feasible in use necessary significant care of the toxicity of ethylene glycol, especially in the open air, under the situation that lacks cleaning water, many inconvenience have been brought to the operator.The potential of hydrogen of cooling fluid also is a very important index, if cooling fluid presents acidity, to the metal in the engine system comparatively intensive corrosion will be arranged, fall the work-ing life of reducing engine greatly, traditional potential of hydrogen relies on adding potassium hydroxide or these highly basic of sodium hydroxide to regulate, but potassium hydroxide or sodium hydroxide only can be regulated potential of hydrogen, can not play other any effect, and price are higher.
Summary of the invention
The present invention overcomes the deficiencies in the prior art just, glycerol with more environmental protection substitutes traditional ethylene glycol, with sodium phosphate and phosphorylated ligand altogether as cooling fluid acidity-basicity regulator and anticorrosive additive, reach and both have low-freezing, has erosion resistance again, simultaneously the also comparatively cheap purpose of cost.
The present invention seeks to be achieved through the following technical solutions:
This cooling fluid is made of according to mass percent following component:
Glycerol: 40-60%,
Distilled water: 38.2-58.2%,
Sodium phosphate: 0.5%,
Phosphoric acid: 0.05%,
SODIUMNITRATE: 0.5%,
Water glass: 0.5%,
The phenylpropyl alcohol triazole: 0.05%,
Borax: 0.2%.
The effect of glycerol is a pour point depressant, the addition of 40%-60% can make the zero pour of cooling fluid reduce to subzero 40 to subzero 60 the degree about, the addition of glycerol is big more, zero pour is low more, corresponds to actual needs very much;
The effect of sodium phosphate is a sanitas, after sodium phosphate is water-soluble, presents alkalescence, and its effect is to suppress the corrosion of cooling fluid to iron and steel and aluminium;
The effect of SODIUMNITRATE also is a sanitas, and its effect is to suppress the corrosion of cooling fluid to iron and steel;
The effect of water glass also is a sanitas, and its effect is to suppress the corrosion of cooling fluid to aluminium alloy;
The effect of phenylpropyl alcohol triazole also is a sanitas, and its effect is to suppress the corrosion of cooling fluid to copper alloy;
The effect of borax is the conditioning agent and the stablizer of cooling fluid potential of hydrogen, and it works the potential of hydrogen of regulating cooling fluid, makes cooling fluid keep the effect of alkalescence, and borax also has the effect of stable cooling fluid potential of hydrogen;
Phosphoric acid is as a kind of strong acid, and it and sodium phosphate cooperate the potential of hydrogen that can regulate cooling fluid, thereby plays the effect of adjusting and stable cooling fluid potential of hydrogen;
The test effect of technical solution of the present invention is as follows:
| Add 40% glycerol | Add 60% glycerol | |
| Zero pour | -38.5℃ | -60.5℃ |
| PH value | 10.5 | 9.8 |
| The cast iron erosion resistance | -0.027 | -0.028 |
| The aluminium erosion resistance | -0.015 | -0.016 |
| The steel erosion resistance | -0.009 | -0.009 |
| The copper erosion resistance | -0.012 | -0.012 |
