The engine outer surface washing agent is prepared from environment-friendly nontoxic raw materials, possesses excellent corrosion resistance, and is a water-based washing agent with alkalescence; plastic and rubber parts are not damaged by application of the engine outer surface washing agent; and product stability is ensured.
Description
Technical field
The invention belongs to chemical technology field, more particularly to a kind of environment-friendly cleaning agent with high-effective cleansing effect,
It is mainly used in the cleaning of electromotor outer surface.
Background technology
During life-time service, electromotor outer surface can produce a lot of greasy filth to automobile, and these greasy filth clean meeting not in time
Cause the continuous accumulation of engine surface dust, make rubber parts aging, cracking, corrosion, have a strong impact on its using and safety.Separately
Outward, the automotive wire bundle of electromotor outer surface is chronically at strong voltage and is exposed in the environment of high temperature hostile, easily aging, Testudiniss
Split, the problem leaked electricity occurs, thus leading to that engine operating condition is deteriorated, oil consumption is increased, be increased maintenance cost, gently then damaged circuit
Part is heavy then be likely to result in self-burning of vehicle.Driving for greater safety rides in an automobile, more and more necessary to the cleaning of electromotor.
At present, common on market electromotor external surface cleaning agent mainly has two kinds, and one kind is solvent-borne type, its cleaning capacity
Relatively strong, but abnormal smells from the patient is very big, and also toxicity is stronger, and human body and surrounding are harmful to；Another kind is aqua type, its cleaning function
Preferably, but great majority be strong basicity, electromotor can be caused damage.For synthesis, existing electromotor external surface cleaning agent
High-effective cleansing, environmental protection, the comprehensive cleaning requirement such as safe and nontoxic, harmless to electromotor can't be reached, need to develop a kind of
It is specifically designed for the abluent of electromotor outer surface.
Content of the invention
Goal of the invention：For the defect of prior art, the invention provides one kind has high-effective cleansing effect and environmental protection
Nontoxic electromotor external surface cleaning agent.
Technical scheme：The electromotor external surface cleaning agent of the present invention, comprises the raw material of following weight percentage：
Described anion surfactant has preferable decontamination, moistening and emulsification, preferably lauryl sulphate acid
At least one in sodium, polyoxyethylenated alcohol sodium sulfate and α-sodium olefin sulfonate.
Preferably, in described anion surfactant, the content of polyoxyethylenated alcohol sodium sulfate is 30-100%.
It is further preferred that the content of polyoxyethylenated alcohol sodium sulfate is 80- in described anion surfactant
100%.
Described nonionic surfactant has splendid infiltration, emulsifying, dispersion and reduces capillary effect, this
It is preferably in fatty alcohol-polyoxyethylene ether, alkyl polyglucoside, alkylphenol polyoxyethylene and coconut oil diethanol amide in invention
At least one.
Preferably, in described nonionic surfactant, the content of fatty alcohol-polyoxyethylene ether is 40-50%.
Entered with nonionic surfactant using anion surfactant in the electromotor external surface cleaning agent of the present invention
Row is compounding, has strong osmotic, demulsibility energy, removes greasy filth, the dirt of engine surface, brings electromotor outer surface high
The cleaning protection of effect, is easy to engine radiating.
Described metal inhibitor has the Corrosion Protection of fabulous ferrum and steel, will not corrode the metal that abluent is contacted
Part, at least one in preferred triethanolamine borate, oleic diethanola mide borate ester and sodium gluconate in the present invention.
Preferably, described metal inhibitor be triethanolamine borate and sodium gluconate, and triethanolamine borate and
The weight of sodium gluconate is than for 1:0.5-1.5.
It is further preferred that described metal inhibitor is triethanolamine borate and sodium gluconate, and triethanolamine boron
The weight of acid esters and sodium gluconate is than for 1:1.
Described environment-friendly type solvent is D- hesperidene, and it is the high environment-friendly type solvent of safety.
Described acid-base modifier is at least one in sodium carbonate, sodium bicarbonate and triethanolamine.
Preferably, described acidity regulator is triethanolamine.
Using during acid-base modifier, in order to adjust the acid-base value of gained cleaning agent further, general cleaning agent is strong basicity,
Electromotor can be caused to damage.The electromotor external surface cleaning agent of the present invention is in alkalescence after being adjusted by acid-base modifier
Aqua type abluent, be different from solvent-borne type and strong alkaline cleaner, lossless plastics and rubber parts, more stable.
The electromotor external surface cleaning agent of the present invention can using the preparation of this area conventional method, will each composition press proportioning by
Mixed in individual addition deionized water, and stirred.During use, this cleaning agent is sprayed on engine cylinder by watering can
External surface, infiltrates 5-10 minute naturally, is rinsed with low pressure tap water and can remove the obstinate oil stain being attached to outer surface and amass
Charcoal, recovers the original gloss of engine surface, simple to operate, quick and easy.
Beneficial effect：It is compared to prior art, the motivation external surface cleaning agent of the present invention adopts the raw material of environment-protecting asepsis
Allotment forms, and has superior Corrosion Protection；Be in weakly alkaline aqua type abluent, lossless plastics and rubber parts it is ensured that
The stability of product.
Specific embodiment
Table 1 material source explanation table
Embodiment 1-7
The electromotor external surface cleaning agent of embodiment 1-7 is raw materials used and corresponding weight percentage is as follows：
Table 2
Preparation method：Electromotor external surface cleaning agent in embodiment 1-7 is by adding each raw material one by one by formula ratio
Enter in deionized water, stir acquisition.
Performance test：
Steady to the washing power of the electromotor external surface cleaning agent of embodiment 1-5, corrosivity, high-temperature stability and low temperature below
Qualitative test：Tested by QB/T 2117-1995 general water-base metal detergent requirement, test result is shown in Table 3 and table 4；Its
He the results are shown in Table 4 by testing performance index.
Table 3 high-efficiency environment friendly h type engine h external surface cleaning agent washing power test result
