Abstract
A kind of high efficienct corrosion retarder for IC engine cooling liquid.This inhibiter is made up of sodium tetraborate, Sodium Nitrite, water glass, benzotriazole, polymaleic anhydride, ethylenediamine tetraacetic methene phosphoric acid and deionized water.Raw material resources of the present invention is extensive, cost is low.Slowed down corrosive nature, prolonged turn(a)round part of cooling system such as diesel locomotive steam jacket, water pumps.This inhibiter has corrosion inhibition preferably to aluminum component, can avoid using cast iron water pump, for finned type aluminum-made radiator is applied the condition created on diesel locomotive.
Description
The present invention relates to the additive in the diesel locomotive usefulness cooling fluid.
Beeliner is related to the work-ing life of parts such as steam jacket, body, scatterer water pump, heat exchanger, electric cooler and heat dissipating section with the quality of circulating cooling liquid quality.Good cooling fluid can make the cylinder rapid heat dissipation, so that give full play to locomotive power, saving fuel oil, prolongation locomotive maintenance cycle.
At present, to have adopted silicon be 1#, 2# compound prescription to the circulating cooling liquid that uses of China railways diesel locomotive.This cooling fluid is to cylinder sleeve, the aluminium matter water pump seriously corroded of diesel locomotive.This has not only strengthened maintenance workload, and has increased maintenance cost.Abroad inhibiter has the super freeze-proof rust-preventive agent of Japanese bird Ai Sitong preferably.This rust-preventive agent has corrosion inhibition preferably.Can prolong the work-ing life of diesel locomotive component.But on the surface of cylinder sleeve body, still have cavitation corrosion hole point.Simultaneously, the composition more complicated of this rust-preventive agent, cost is very high, is unfavorable for extensively promoting the use of on diesel locomotives in China.
The invention provides a kind of diesel locomotive cooling fluid high-efficient corrosion inhibitor.It is 1#, 2# compound prescription cooling fluid that the performance of this inhibiter is better than the present general silicon of China.And cost has only one of percentage of the super freeze-proof rust-preventive agent of Japanese bird Ai Sitong.Constituent also lacks than Japanese rust-preventive agent, prepares also easy.
The mechanism of action of high efficienct corrosion retarder for IC engine cooling liquid:
The essence of the inhibition mechanism of high efficienct corrosion retarder for IC engine cooling liquid is " one-tenth film theory ".The thickness of film, intensity and stability are the keys of decision corrosion mitigating effect.Under conditions such as specific temperature, pressure, the content of the various compositions of inhibiter is directly determining the formation and stability of the pH value and the film of solution.Particularly the content of silicon-dioxide is directly connected to the formation of hard silicon fiml in the cooling fluid.Be related to the ability of resisting vibratory cavitation.
Various additive roles are as follows in the inhibiter:
1, sodium tetraborate: it is a kind of pH value inhibiter.(pH value is about 9.0).Iron there is good corrosion inhibition.It is mainly with the topped anode surface at iron of adsorptive type film.Thereby slowed down the anodic electrochemical reaction and reached the purpose of inhibition.The protective membrane that generates at iron surface mainly is Fe
3O
4, Fe
2O
3And intermediate compound.
2, Sodium Nitrite: it is to belong to the anodic corrosion inhibitor that passivation type and adsorptive type have concurrently.Can weaken the anodic electrochemical reaction.Simultaneously, because nitrite ion is adsorbed on the surface of iron, and has occupied the most active position in the lattice, thereby slowed down the response intensity of iron in solution.Make iron be in passive state.Sodium Nitrite also has significant corrosion inhibition to other ferrous metal.
3, water glass: it is a kind of sedimentation type inhibiter.It is insensitive to pH value.When higher or low, can both form harder siliceous protective membrane at pH value in the metallic surface.When silicon film thickness reaches 200～500A °, ferrous metal and non-ferrous metal all there is good corrosion inhibition.
4, benzotriazole: it can play complexing action with copper, generates stable complex protection film.It has fabulous corrosion inhibition to copper and copper alloy, and aluminium is also had good corrosion inhibition.
5, polymaleic anhydride and ethylenediamine tetraacetic methene phosphoric acid: its compound action not only has corrosion inhibition to ferrous metal, and by synergistic effect, skin effect, stabilizing water quality is eliminated residual harness in the water, plays scale effect.
The constituent and the weight percent of the super freeze-proof rust-preventive agent of Japan bird Ai Sitong are:
1, ethylene glycol: 78%
2, Sodium phosphate dibasic: 3.47%
3, trolamine: 2.0%
4, ammonium benzoate: 1.6%
5, benzotriazole: 1.05%
6, Sodium orthomolybdate: 0.93%
7, three oxidation azoles: 0.10%
8, pure water and other: 12.85%
The diesel locomotive cooling fluid with the constituent and the weight percent of high-efficient corrosion inhibitor is:
1, sodium tetraborate: 46.9～50%
2, Sodium Nitrite: 49.9～53%
3, water glass: 0.08～0.1%
4, benzotriazole: 0.008～0.01%
5, polymaleic anhydride: 0.0008～0.001%
6, ethylenediamine tetraacetic methene phosphoric acid: 0.0008～0.001%
The process for preparation of high-efficient corrosion inhibitor is as follows:
The per-cent of at first pressing afore mentioned rules is with sodium tetraborate and Sodium Nitrite grinding powder.Then, drop into polymaleic anhydride and ethylenediamine tetraacetic methene phosphoric acid.At last, make benzotriazole dissolving with ethanol after, in the plastics bag of packing in the lump.During use, the article in the above-mentioned plastics bag are together dropped in the deionized water together with water glass.The total amount of above-mentioned materials and the ratio of deionized water are 1: 157.
Embodiment:
Be 45% sodium tetraborate, 48% Sodium Nitrite grinding powder with content at first, put 0.0009% polymaleic anhydride and 0.0009% ethylenediamine tetraacetic methene phosphoric acid then into.At last, make content be the dissolving of 0.005% benzotriazole with ethanol after, put in the plastics bag in the lump.During use, article in the above-mentioned plastics bag are together dropped in the deionized water together with 0.09% water glass.The ratio of the total amount of article and water glass and deionized water is 1: 157 in the above-mentioned plastics bag.
The present invention compared with prior art has the following advantages:
1, raw material resources is extensive, cost is low, only has the super freeze-proof of Japanese bird Ai Sitong anti-One of percentage of rust agent;
2, slow down the corrosiveness of each parts of combustion motor car cooling system, prolonged turn(a)round;
3, aluminum component there is preferably corrosion inhibition, can avoids using cast iron water pump, for the plate-fin aluminum radiator is applied the condition created at diesel locomotive;
4, easy to use;
5, reduced pollution to environment.
