Abstract
A coolant oil used for an automobile engine comprises chemical compositions: 8-22% of de-ionized water, 75-90% of diatomic alcohol, 0.8-5% of monohydric or diatomic fatty acid containing six carbon atoms and 0.5-2.5% of caustic alkali. The coolant oil has the freezing point within the range of -38 to -42 DEG C and the boiling point within the range of 125-140 DEG C, thus adapting to the needs of different engines. The coolant oil has the characteristics of low temperature heat accumulation and high temperature heat dissipation, and is relevant to the working process of the engine, so as to improve the working temperature of the engine by over 10 DEG C and have no corrosiveness.
Description
One, technical field
The present invention relates to a kind ofly for cooling chemical composition, is exactly a kind of cooling oil for car engine.
Two, background technology
Automobile making is a systems engineering.When China is strided forward to automobile making power by automobile making big country, its supporting non-key technologies should be with core technology synchronized development.
China's engine-cooling system is used the deicing fluid of 100～108 ℃ of boiling points as heat-eliminating medium (cooling fluid) always for many years, and when engine temperature surpasses 100 ℃, easily producing steam affects heat-transfer effect.It is reported have and use the water-free cooling ，Dan China too high engine operating temperature of boiling point up to 191 ℃ can affect machine oil viscosity, affect its sealing and lubricant effect abroad.
Three, summary of the invention
The present invention aims to provide a kind of cooling oil for car engine of applicable China's national situation, and technical problem to be solved is cooling oil moderate boiling point and adjustable.
This cooling oil is one group of chemical composition, and each component has following weight percent:
Deionized water 8～22%
Dibasic alcohol 75～90%
Organic acid 0.8～5%
Caustic alkali 0.5～2.5%.
Described dibasic alcohol is selected from one or more mixing dibasic alcohol in ethylene glycol or propylene glycol or hexylene glycol, and during mixing, mutual ratio is any.Preferred propylene glycol.
Described organic acid is selected from more than six carbon atom monobasic or binary of fatty acids as one or more mixing acid in caproic acid, hexanodioic acid, enanthic acid, sad, suberic acid, n-nonanoic acid, nonane diacid, capric acid, sebacic acid, lauric acid etc., and during mixing, mutual ratio is any.The monobasic and the binary of fatty acids that preferably mix.
Described caustic alkali is selected from sodium hydroxide (NaOH) or potassium hydroxide (KOH), preferably KOH.It is 7～8.5 that caustic alkali makes the pH value of cooling fluid.
The technical program is preferred
Deionized water 12～18%
Propylene glycol 80～85%
Organic acid 1～3%
Potassium hydroxide 1～2%.
Dibasic alcohol and the organic acid of metering are in proportion added in modulation kettle, heat and stir, being warming up to 80～100 ℃ of insulations 0.5～1 hour, then adding the deionized water that is dissolved with caustic alkali, cooling outward appearance clarification, the transparent cooling oil of obtaining after stirring, pH value is 7～8.5.
The freezing point of this cooling oil can change at-38～-42 ℃, boiling point between 125～140 ℃, and when deionized water consumption is on the high side, freezing point is higher, boiling point is lower, and instead freezing point is lower, boiling point is higher.This makes this cooling oil can adapt to the needs of different engines.
Engine is when starting, and thermostat and electronic fan are closed, and is intended to reach rapidly working temperature and saves start time.It is slow that this cooling oil dispelled the heat in time below 100 ℃, and in when more than 100 ℃, more approach between boiling section heat-transfer effect better, the working condition of the very proper engine of characteristic of this low-temperature heat accumulating and high temperature heat radiation.Use this cooling oil, the working temperature of engine can improve 10 ℃ of left and right, and does not affect the performance of machine oil.
This cooling oil non-corrosiveness.Applicant once carried out the weightless simultaneous test of static corrosion to six kinds of metals, carried out contrast test with import water-free cooling.Test conditions is constant temperature 336 hours at 101 ℃, constant temperature finish rear cooling, clean, be dried, weigh, to observe weightlessness (mg) situation.Sample is 50 * 25 * 2.5mm standard test piece.Result is as follows:
The weightless standard of this cooling-oil inlet of metal water-free cooling SH-0088
Red copper 0-3-10
Brass 0-2-10
Steel 0 0-10
Cast iron 0+1-10
Scolding tin+1-6.0-30
Aluminium 0+2-30.
Four, embodiment
1, remove 10 parts of ionized waters, 5 parts of hexylene glycols, 80 parts of propylene glycol, drop into be in harmonious proportion in still, stir and are warming up to 80 ℃, then add 0.5 part of enanthic acid, 2 parts of nonane diacids, KOH2.5 part, coolingly after 85 ℃ of insulation half an hour is clarified, the cooling oil of transparent, pH8.4.
2, remove 20 parts of ionized waters, 75 parts of propylene glycol, sad 1.5 parts, 1.5 parts of sebacic acid, KOH2 part, operation is with example 1.Clarified, the cooling oil of transparent pH8.0.
3,15 parts, ion of water intaking, 82 parts of propylene glycol, sad 1 part, 1 part of sebacic acid, 1 part of KOH, operation with example 1. clarified, the cooling oil of transparent pH7.5.
Claims (1)
1. a cooling oil for car engine, is characterized in that: remove 15 parts of ionized waters, 82 parts of propylene glycol, drop into and be in harmonious proportion in still, stir and be warming up to 80 ℃, then add sad 1 part, 1 part of sebacic acid, KOH1 part, 85 ℃ of insulations are cooling after half an hour is clarified, the cooling oil of transparent, pH7.5.
