Abstract
The invention relates to a water-free coolant for an engine, particularly relates to a water-free coolant which does not contain a water component and contain not less than 55wt% of propylene glycol used as a main material, and particularly relates to a low-freezing-point, high-boiling-point, corrosion-resistant, energy-saving and environmentally-friendly long-lasting water-free coolant for the engine.
Description
Technical field
The present invention relates to the no water coolant of a kind of engine, particularly a kind of low-freezing, high boiling point, erosion-resisting engine long-acting liquid coolant.
Technical background
The application of engine coolant is along with the life of prolonging of engine and automobile, and year surplus application has 100 is engine to be cooled off as refrigerant with water at first.Along with development of technology, so far, existing water is that base-material mixes and more additional functional agents have constituted water system cooling fluid of all categories or frostproofer with materials such as ethanol, ethylene glycol, Diethylene Glycol, glycerol, propylene glycol.These commercially available type of engine cooling fluids, water content is at 20%-80%, so just there is a common problem, i.e. low, the easy evaporation of the boiling point that brings by water, replenish problems such as water body is frequent, make water as the engine refrigerant separately, also exist and boil, incrustation scale, vapour lock, cavitation erosion, scale, to freeze, even the technical problems such as bad body and corrosion engine-cooling system that expand.
Goal of the invention
The present invention is directed to the deficiency of above-mentioned technology, design is developed does not a kind ofly have water component to participate in, and is main base-material with propylene glycol, and the engine of low-freezing, high boiling point, anticorrosive, energy-saving and environmental protection is with long-acting no water coolant.
Summary of the invention
The present invention is achieved by the following technical solutions:
This engine does not have water coolant and is made of according to weight percent following component:
1.2-propylene glycol, 1.3-propylene glycol, ethylene glycol, Diethylene Glycol, diethylene glycol dimethyl ether, diethylene glycol diethyl ether, diethylene glycol monobutyl ether and dibutyl ethylene glycol ether are wherein a kind of to three kinds of 89.5%-99.909%.
Mercaptobenzothiazole, tolyltriazole, azimido-toluene and phenylpropyl alcohol triazole be one or both 0.03%-3.0% wherein.
Wherein a kind of 0.03%-3.0% of Sodium Benzoate and SODIUMNITRATE.
Sodium orthomolybdate 0.03%-3.0%.
Sodium hydroxide, potassium hydroxide, yellow soda ash and salt of wormwood is one or both 0.001%-1.5% wherein.
Described 1.2-propylene glycol is by weight more than 55%.
When described 1.2-propylene glycol and 1.3-mixed with propylene glycol were used, its mixture was by weight more than 70%.
Described 1.2-propylene glycol, 1.3-propylene glycol, ethylene glycol, Diethylene Glycol, diethylene glycol dimethyl ether, this diethylene glycol diethyl ether of diethyl, diethylene glycol monobutyl ether and dibutyl ethylene glycol ether are the antifreeze/cooling/heat-transfer fluid of non-water system matrix.
Described mercaptobenzothiazole, tolyltriazole, azimido-toluene and phenylpropyl alcohol triazole all are anti-corrosion of metal inhibiter, can prevent the corrosion of copper member, simultaneously aluminium, cast iron are had certain corrosion inhibition.
Described Sodium Benzoate and SODIUMNITRATE all are anti-corrosion of metal inhibiter, can prevent the corrosion of iron or cast iron, and have to a certain degree the inhibition scolder and the corrosion of aluminium.
Described Sodium orthomolybdate also is the anti-corrosion of metal inhibiter, is mainly the corrosion inhibitor of scolder, and the every other corrosion of metal of inhibition is arranged.
Described sodium hydroxide, potassium hydroxide, yellow soda ash and salt of wormwood use as neutralizing agent.
