Abstract
The invention relates to the technical field of a cooling liquid and particularly relates to a vehicle engine cooling liquid. An additive composition consists of the following components in percentage by mass: 30 to 60 percent of glycol, 0.15 to 0.3 percent of benzotriazole, 0.05 to 0.1 percent of sodium benzoate, 0.5 to 1.5 percent of sebacic acid, 0.1 to 1.0 percent of azelaic acid, 0.5 to 1.0 percent of sodium metasilicate, 0.2 to 0.5 percent of a silicate stabilizer, 0.001 to 0.01 percent of an antifoaming agent, 0.05 to 0.8 percent of potassium hydroxide, 0.002 to 0.006 percent of dye and the balance of deionized water. The vehicle engine cooling liquid adopts a novel mixed formula which uses organic substances as the main materials and uses inorganic substances as the auxiliary materials, has a good anticorrosive effect and a stable performance, has no precipitates, does not comprise substances which pollute the environment and are harmful for human bodies, such as amine substances, nitrite, phosphate and the like, is low in cost, can be widely applied to a vehicle engine cooling system and is suitable to be used in various areas.
Description
Technical field
The present invention relates to cooling fluid technical field, particularly a kind of automobile engine cooling liquid.
Background technology
Engine-cooling system has water-cooled and air-cooled two kinds of types of cooling, and automobile generally adopts cooling by water.Automobile engine cooling liquid is the heat-eliminating medium of car water engine, is to make the requisite integral part of the normal operation of engine.There is the functions such as cooling, protection against corrosion, antiscale be antifreeze.
In recent years, along with the development of automobile technology and material, for reducing automotive dead weight, energy-saving and emission-reduction, the use of aluminum metal parts is more and more extensive, as aluminium alloy heat radiator, cylinder cap, water pump etc.Therefore the protection for engine aluminum alloy seems particularly important.
Meanwhile, people start pay attention to day by day environmental protection, for there being the material that environmental pollution or human body are harmful, as amine substance, nitrite, phosphoric acid salt etc. will progressively be eliminated.The use of conventional inorganic type cooling fluid can be restricted.At present, full organic engine deicing fluid is less, and because production cost is higher, is difficult to be widely used.
Summary of the invention
The present invention is directed to deficiency of the prior art, a kind of automobile engine cooling liquid that organic acid and inorganic inhibitor are used in conjunction with is provided.
Technical scheme of the present invention is:
An automobile engine cooling liquid, described compositions of additives forms according to following quality per distribution ratio: ethylene glycol 30-60%, benzotriazole 0.15-0.3%, Sodium Benzoate 0.05-0.1%, sebacic acid 0.5-1.5%, nonane diacid 0.1-1.0%, Starso 0.5-1.0%, silicate stabilizers 0.2-0.5%, defoamer 0.001-0.01%, potassium hydroxide 0.05-0.8%, dyestuff 0.002-0.006%, deionized water are surplus.
Preferably, described silicate stabilizers is organo-siloxane compounds.
Preferably, described silicate stabilizers is γ-(sodium sulfonate) propyl-siloxane.
Preferably, described defoamer is methyl-silicone oil or methacrylic ester.
Beneficial effect of the present invention:
(1) automobile engine cooling liquid of the present invention adopts and take organism as main, and inorganics is auxiliary novel mixed type formula, can reach long-acting object.
(2) favorable anti-corrosion effect of the present invention, stable performance, without precipitation.
(3) the present invention is containing the environmental pollutions such as amine substance, nitrite, phosphoric acid salt, material that human body is harmful.
(4) cost of the present invention is low, can be widely used in car engine cooling system, is applicable to each area and uses.
