Description

A kind of environment protecting type engine test-run a machine liquid

Technical field

The present invention relates to a kind of motor car engine test-run a machine liquid, relate in particular to the environment protecting type engine test-run a machine liquid with alternating hot and cold Qi – liquid phase antirust ability, be applied to all kinds of motor car engine industries.

Background technology

Before engine has all been assembled and has been dispatched from the factory, carry out trial trip to every engine, Here it is so-called test-run a machine, in the normal operation of certain load, running, power and temperature Imitating engine, whether the quality of debuging of investigating engine has or not the mistakes and omissions dress, can run well; Whether the performance of dispatching from the factory of check engine reaches technical requirements, and carries out early stage preliminary break-in.

In the test-run a machine process, the cooling system of engine will pour into test-run a machine liquid.The producer of current domestic professional production control apparatus for general purpose engine test-run a machine liquid is less, quality product only rests on the antirust requirement of short-term while meeting test-run a machine, and the level that contains the 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 cooling fluid that the production line entrucking uses to carry out test-run a machine, the complete solution that bleeds off of test-run a machine returns to storage tank, recycles.During due to the engine test-run a machine, top temperature is 90 ℃～95 ℃, and the test-run a machine time is 10～30min, and the test-run a machine solution used therebetween will inevitably produce steam; Further working as solution is let go, having in the engine-cooling system of complex construction will inevitably residual a small amount of test-run a machine solution, the state that causes system to coexist in the cold liquid phase of a kind of cold air Xiang –, so, the test-run a machine of engine from dispatching from the factory, be stored in entrucking during this period of time, in fact experienced the Re Ye Xiang – hot phase of short-term and the alternation corrosion process that long-term cold Ye Xiang – cold air coexists mutually.And the cooling fluid antiseptic power on ordinary meaning is strong, refer in cooling system and poured into cooling fluid, associated components can guarantee that cooling system is not corroded while fully contacting with cooling fluid, but when cooling fluid is let go, during state that in system, also residual a small amount of cooling fluid coexists system for a long time in the cold liquid phase of cold air Xiang –, because cooling fluid does not contain the volatile rust prevention composition, its main component is ethylene glycol, it is acid that facile hydrolysis is, in fact more easily make the cooling system corrosion, thereby affect the normal functional quality of engine 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 formula, because Sodium Nitrite is poisonous, the human body Long Term Contact is easily carcinogenic, its harm to human body has caused the common concern in market, and limited in the use, after product is used, discharging of waste liquid easily causes 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 defect 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 engine test-run a machine liquid has alternating hot and cold Qi – liquid phase antirust ability to various metals, not containing materials such as nitrite, amine salt, phosphoric acid salt, nontoxic, harmless, free from environmental pollution, product recycles good stability, uses safety and environmental protection, can be applicable to all kinds of motor car engines front test-run a machine that dispatches from the factory.

For achieving the above object, the invention discloses a kind of environment protecting type engine test-run a machine liquid, the moiety that it comprises following concentration: ethylene glycol 120～200g/L, polycarboxylate (TH-361) 6～15g/L, Sodium.beta.-phenylacrylate 0～2.5g/L, P-hydroxybenzoic acid 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, MBT 0.2～1g/L, Starso 2～6g/L, water-soluble pigment 0.5～1g/L, deionized water surplus.

Preparation method of the present invention comprises the following steps:

(1) the deionized water that takes formula ratio adds in stainless steel cauldron, ethylene glycol 120～the 200g/L that adds formula ratio, P-hydroxybenzoic acid 10～the 20g/L that slowly adds successively formula ratio under whipped state, Sunmorl N 60S 3.5～8.5g/L, sodium phytate 0.5～1.5g/L, Starso 2～6g/L, stir 20～30min to dissolving fully;

(2) take the benzotriazole 0.5～2g/L of formula ratio, MBT 0.2～1g/L slowly joins in mixture (1) under whipped state, continues to stir 15～20min to dissolving fully;

(3) take polycarboxylate (TH-361) 6～15g/L of formula ratio, sebacic acid 3～6g/L slowly joins in mixture (2) under whipped state, continues to stir 5～10min to dissolving fully;

(4) take the water-soluble pigment 0.5～1g/L of formula ratio, join in mixture (3), stir 3～5min and be product.

By the cooperation of described each component materials, thereby can be achieved as follows advantage:

1. to comprising that the various 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, containing nitrite, amine salt, phosphoric acid salt etc., corrosion-free, non-stimulated to respiratory system, skin, can not endanger the healthy of operator, environmentally safe, used safety.

3. recycle stable in properties, long quality-guarantee period.

4. good with the cooling fluid intermiscibility, do not affect the antiseptic property of entrucking cooling fluid.

5. the Engine Surface coating is had no effect, can meet the front test-run a machine of dispatching from the factory of all kinds of motor car engines, reach the test-run a machine technical requirements.
