Background technology
Mover all assemble accomplish dispatch from the factory before; To carry out trial trip to every mover, Here it is so-called test-run a machine, the i.e. normal operation of simulated engine under certain load, running, power and temperature; Whether the quality of debuging of investigating mover has or not the mistakes and omissions dress, can run well; Whether the performance of dispatching from the factory of check mover reaches technical requirements, and carries out early stage preliminary break-in.
The cooling system of mover will pour into test-run a machine liquid in the test-run a machine process.The producer of the universal mover test-run a machine of present domestic professional production liquid is less; Quality product only rests on the antirust requirement of short-term when satisfying test-run a machine; And the level that contains objectionable impuritiess such as nitrite, most of to quality and the higher engine production factory of environmental requirement, what take is directly to pour into the high-performance enginer quench liquid that the production line entrucking uses to carry out test-run a machine; Test-run a machine finishes and bleeds off solution and return storage tank, recycles.Because top temperature is 90 ℃~95 ℃ during the mover test-run a machine, the test-run a machine time is 10~30min, and the test-run a machine solution that uses therebetween will inevitably produce steam; Further working as solution is bled off; Having in the engine-cooling system of complex construction will inevitably residual a spot of test-run a machine solution; Causes system is in the state of the cold liquid phase coexistence of a kind of cold air Xiang –; So, the test-run a machine of mover before dispatch from the factory, being stored in the entrucking during this period of time, the Re Ye Xiang – hot phase that has in fact experienced short-term and secular cold Ye be the alternation corrosion process that coexists mutually of – cold air Xiang.And the quench liquid antiseptic power on the ordinary meaning is strong; Be meant in cooling system and poured into quench liquid, associated components can guarantee that cooling system is not corroded when fully contacting with quench liquid, is bled off but work as quench liquid; When also residual a small amount of quench liquid makes system be in the state of the cold liquid phase coexistence of cold air phase – for a long time in the system; Because quench liquid does not contain the volatile rust prevention composition, its staple is a terepthaloyl moietie, and it is acid that facile hydrolysis is; In fact more be prone to make the cooling system corrosion, thereby influence normal functional quality of mover and work-ing life.
Number of patent application is 200910217784
.2 " three-prevention testing liquid for automobile engine before leaving factory "; Contain Sodium Nitrite in its prescription, because Sodium Nitrite is poisonous, the long-term contact of human body is prone to carcinogenic; It has caused the common concern in market to the harm of human body; And limit in the use, product uses the back discharging of waste liquid to be prone to cause that water pollution works the mischief to environment, so the patented product does not have the feature of environmental protection.
Summary of the invention
The defective that The present invention be directed to the existence of above-mentioned background technology provides a kind of environment protecting type engine test-run a machine liquid; This mover test-run a machine liquid has alternating hot and cold Qi – liquid phase antirust ability to multiple metal, does not contain materials such as nitrite, amine salt, phosphoric acid salt, and is nontoxic, harmless; Free from environmental pollution; Product recycles good stability, and environmental protection safe in utilization can be applicable to all kinds of motor car engines preceding test-run a machine that dispatches from the factory.
For realizing above-mentioned purpose, the invention discloses a kind of environment protecting type engine test-run a machine liquid, it comprises the moity of following concentration: terepthaloyl moietie 120~200g/L; Polycarboxylate (TH-361) 6~15g/L, Sodium.beta.-phenylacrylate 0~2.5g/L, PHB sodium 10~20g/L; Sebacic acid 3~6g/L, sodium phytate 0.5~1.5g/L, Sunmorl N 60S 3.5~8.5g/L; Benzotriazole 0.5~2g/L, 2-mercapto benzothiazole 0.2~1g/L, Starso 2~6g/L; Water-soluble pigment 0.5~1g/L, the deionized water surplus.
Preparing method of the present invention may further comprise the steps:
⑴ the deionized water that take by weighing formula ratio adds in the stainless steel cauldron; Terepthaloyl moietie 120~the 200g/L that adds formula ratio; PHB 10~the 20g/L that under whipped state, slowly adds formula ratio successively, Sunmorl N 60S 3.5~8.5g/L, sodium phytate 0.5~1.5g/L; Starso 2~6g/L stirs 20~30min to dissolving fully;
⑵ take by weighing the benzotriazole 0.5~2g/L of formula ratio, and 2-mercapto benzothiazole 0.2~1g/L slowly joins under whipped state in the mixture of ⑴, continues to stir 15~20min to dissolving fully;
⑶ take by weighing polycarboxylate (TH-361) 6~15g/L of formula ratio, and sebacic acid 3~6g/L slowly joins under whipped state in the mixture of ⑵, continues to stir 5~10min to dissolving fully;
⑷ take by weighing the water-soluble pigment 0.5~1g/L of formula ratio, joins in the mixture of ⑶, stirs 3~5min and be product.
Through the cooperation of said each component materials, thereby can realize following advantage:
1. to comprising that multiple metals such as steel, iron, aluminium, scolding tin, brass, red copper have alternating hot and cold Qi – liquid phase rustless property.
2. nontoxic, the environmental protection of product does not contain nitrite, amine salt, phosphoric acid salt etc., and it is non-stimulated that respiratory system, skin are not had burn into, can not endanger the healthy of operator, and environmentally safe is safe in utilization.
3. recycle stable in properties, long quality-guarantee period.
4. good with the quench liquid intermiscibility, do not influence the antiseptic property of entrucking quench liquid.
5. the Engine Surface coating is had no effect, can satisfy the preceding test-run a machine of dispatching from the factory of all kinds of motor car engines, reach the test-run a machine technical requirements.
