Abstract
The present invention relates to an organic salt cooling fluid for automobiles, which belongs to the technical field of composite organic and inorganic salt. The cooling fluid is characterized in that chemical raw materials comprising chemically pure potassium acetate, sodium benzoate, benzotriazole, sodium metasilicate, sodium tetraborate and the like are added into pure water according to certain portions by weight of constituents. Owing to the addition of solute, the boiling point of a solution is raised, and the freezing point is lowered. The freezing point of the 42% to 60% water solution is from -40 DEG C to -60 DEG C. The chemical raw materials used by the cooling fluid can effectively prevent cooling fluid from eroding ferrous metal, tin, copper, copper alloy, aluminum and aluminium alloy, prevent the invasion of cavitation corrosion and improve the heat conduction speed of cooling fluid and the metal according to the respective performance. As a result, the cooling fluid solves the problems of easy volatilization, easy combustion, easy explosion, low boiling point, high cost and the like existing in the present cooling fluid for automobiles. The cooling fluid provides the antifreeze agent with the functions of boiling prevention, freezing prevention, scale prevention, rust prevention and corrosion prevention and is suitable for water tanks of various automotive vehicles and water circulating systems of various kinds of mechanical equipment. The cooling fluid is suitable to be used at the temperature of -40 DEG C to-60 DEG C.
Description
A kind of organic salt automobile cooling, its starting material wide material sources, the transportation storage security, processing technology thereof is simple and direct, and the scope of application is extensive, compliance with environmental protection requirements.
One, technical field
Belong to the surface chemistry category, be organic and inorganic compounding salt technical field.
Two, background technology
1, to inventing the understanding of " a kind of organic salt automobile cooling "
A kind of organic salt automobile cooling of the present invention, its core are that the boiling point of solution is risen, and zero pour descends.Some character of solution depends primarily on the concentration of contained solute wherein and the character of nonsolute particle itself, and its character is colligative property of solution.Because the affiliation that adds of solute is risen the boiling point of solution, zero pour descends, and the vapor pressure lowering degree of solution depends on the concentration of solution, and the vapor pressure lowering of solution is the basic reason that boiling point rises and zero pour descends.When the aqueous solution reaches zero pour, begin to separate out ice in the solution, along with separating out of ice, the concentration of solution constantly increases, and zero pour constantly reduces, and the concentration of last solution reaches the saturated solution concentration of this solute, and ice and solute are separated out together.Though continue cooling solution this moment, the temperature of solidifying remains unchanged, and till solution all solidified, the principle of Here it is automobile cooling processing and fabricating also was the total technical characterictic of automobile cooling.The selected main raw material of the present invention has: pure water, potassium acetate, Sodium Benzoate, benzotriazole, Starso, sodium tetraborate.These industrial chemicals are through optimum combinations, and development repeatedly, and after a large amount of laboratory and application test, the conclusion that draws is that the present invention has the effect of " five is anti-" is promptly anti-ly boiled, antifreeze, antiscale, antirust, rot-resistant function, and its range of application is very extensive.
2, selected its performance separately of industrial chemicals among the present invention
Potassium acetate can reduce the freezing point of water, and the freezing point of the aqueous solution of its 42%-60% is-40 ℃～-60 ℃, and its boiling point is 118 ℃, can be used as the antifreezing agent of radiator.Benzotriazole can improve the heat conduction velocity of deicing fluid and metal in deicing fluid, and prevents the corrosion of deicing fluid to copper and copper alloy.Sodium Benzoate not only works to reducing freezing point, and can prevent that deicing fluid from producing corrosion to ferrous metal parts.Sodium tetraborate, Starso are good rust-preventive agent.
Three, summary of the invention
1, the purpose of invention " a kind of organic salt automobile cooling "
For solving domestic present employed automobile cooling, problem such as inflammable, explosive, perishable, poisonous and cost height the invention provides a kind of organic salt automobile cooling.It has been paid attention to selecting for use and the technology proportioning of industrial chemicals especially, and has taken into account social benefit and environmental benefit in triturating.It is had anti-boil, antifreeze, antiscale, antirust, rot-resistant function.It is applicable to various Motor vehicles and is furnished with the water circulation system of various mechanical means of water tank and water tank antifreeze.
