Abstract
The invention discloses an anhydrous coolant of an automobile engine, which comprises the following raw materials in parts by mass: 100 parts of 1,2-propylene glycol, 0.1-0.5 parts of benzotriazole, 0.5-1.5 parts of polyamino acid, 0.1-0.5 parts of sodium nitrate, 0.5-1.5 parts of sodium molybdate and 0.1-0.3 parts of dimethicone. The anhydrous coolant of the automobile engine is high in stability, overcomes the technical defect of easy boiling of the traditional hydrous coolant, and facilitates operation of the engine at a full load and a high load.
Description
Technical field
The present invention relates to a kind of cooling fluid, particularly relate to a kind of motor car engine water-free cooling.
Background technology
The full name of deicing fluid should be anti-freeze cooling liquid, means the cooling fluid of antifreeze function.Deicing fluid can prevent the unfrozen cooling fluid when Cold Winter stops and spalling scatterer and freezing engine cylinder block or lid.But we will correct a misunderstanding, deicing fluid is not only winter, and it should use in the whole year.In automobile maintenance project normally, often travel 1 year, need engine fluid be changed.
Cooling fluid is mainly used in car engine cooling system, has cooling, antifreeze, antiscale, anticorrosion, the anti-effect such as to boil.Cooling fluid is primarily of compositions such as frostproofer, water, inhibiter, defoamer, staining agents.The gordian technique of cooling fluid is the reasonable interworking of the additive such as various inhibiter and defoamer.The over-all properties of existing cooling fluid product is still not ideal enough.
Containing water coolant, all there is the technological deficiency of easily " boiling " in tradition.
Summary of the invention
One of technical problem to be solved by this invention is to provide a kind of motor car engine water-free cooling.
The present invention, is achieved by the following technical solution:
A kind of motor car engine water-free cooling, be made up of by mass parts following raw material: 1,2-propylene glycol (No. CAS: 57-55-6) 100 parts, benzotriazole (No. CAS: 95-14-7) 0.1-0.5 part, polyamino acid 0.5-1.5 part, SODIUMNITRATE (No. CAS: 7631-99-4) 0.1-0.5 part, Sodium orthomolybdate (No. CAS: 10102-40-6) 0.5-1.5 part, dimethyl silicone oil (No. CAS: 9006-65-9) 0.1-0.3 part.
Described polyamino acid is one in poly-aspartic-acid (No. CAS: 181828-06-8), poly-L-Leu (No. CAS: 25322-63-8) and polyglycine (No. CAS: 25718-94-9) or its mixture.
Preferably, described polyamino acid is the mixture of poly-aspartic-acid and poly-L-Leu, and wherein the mass ratio of poly-aspartic-acid and poly-L-Leu is 4:1-1:4.
Mixed by above-mentioned raw materials, stir, all material mixings can obtain motor car engine water-free cooling of the present invention.Enter interpolation one step ground, motor car engine water-free cooling pH to 8-9 of the present invention can be regulated with sodium hydroxide or potassium hydroxide again.
Motor car engine water-free cooling of the present invention, stability is high, not blocking pipe, and antifreeze, antirust, ant-scaling is high, effectively can prevent the corrosion to ferrous metal, tin, Copper and its alloy, Al and Alalloy, and overcome the technological deficiency of easy " boiling " that tradition exists containing water coolant, be conducive to engine to run under fully loaded, high loading, can guarantee vehicle on plateau, desert, the safety traffic of the severe environment such as cold, be particularly suitable for military vehicle, high-end vehicles and high-power heavy loading lorry and passenger vehicle.
Embodiment
Below in conjunction with embodiment, the invention will be further described.
Embodiment 1-4
