Abstract

The aircraft body surface cleaning agent is a cleaning agent solution made up by using non-ionix surfactant, cationic surfactant and other adjuvant. It is characterized by that it reasonably selects 4-10% of corrosion inhibitor sodium silicate, so that it not only can clean the surface of aircraft body, but also does not corrode or damage alloy material of body surface and its organic glass window and polycarbonate rubber material. It can be applicable to various airplanes.

Description

External surface cleaning agent of airplane body

The present invention relates to chemical industry articles for use field, especially a kind of hard surface cleaner.

At present, the existing at home and abroad external surface cleaning agent of airplane body that occurs, the solvent that contains 10-15% in the prescription as the external surface cleaning agent of military aircraft, this not only pollutes environment, and the infringement operator is healthy, AEO class tensio-active agent is considered to clean the ideal surfaced promoting agent of aircraft outside surface, but when solvent-free nothing exists, the effect of depolluting of this class tensio-active agent obviously reduces, in addition, its foam is lower, and this is unfavorable to the aircraft cleaning operation, in prescription, add alkylol amide class tensio-active agent and can overcome above-mentioned shortcoming, but its shortcoming is the corrosion that can increase the fuselage material.A kind of vapour-phase inhibitor morphine quinoline in the existing clean-out system, though its corrosion mitigating effect is better, it is a kind of volatile organism, and environment is polluted, and also damages HUMAN HEALTH; A kind of inorganic inhibitor Sodium Nitrite commonly used has been listed in carcinogenic substance; In recent years, Starso is not widely adopted because of it does not pollute to the good corrosion inhibition of aluminium gold material with to environment, but this inhibiter compatibility is not good enough, and is unstable in liquor, is difficult to make the transparent clarification of solution.

The objective of the invention is provides a kind of soil removability strong for overcoming the shortcoming of existing airplane cleaning agent, and the fuselage material is not caused corrosion, and the external surface cleaning agent of airplane body that the intensity of materials used on the aircraft is not impacted.

Technical scheme of the present invention is:

1, do not adopt any solvent, reduce pollution environment caused;

2, select a kind of C ₁₂-C ₁₅The mixture of fatty alcohol-polyoxyethylene ether AEO class tensio-active agent and cats product, it can bring into play good clean effect under the situation that does not have solvent to exist, and foaming properties improves simultaneously, does not also increase the corrosion to the fuselage material;

4, adopt a kind of modulus (Na ₂O: SiO ₂) be the water glass of 1.8-2.4 as inhibiter, it can overcome all shortcomings of in the past using inhibiter, and has the good effect of washing that helps, and increases the soil removability of product.

The present invention adopts following weight proportion prescription;

A, mixed surfactant 8-15%

B, potassium pyrophosphate 2-8%

C, water glass 4-10%

D, water surplus

Above-mentioned mixture table adopts at promoting agent, the mixture of AEO tensio-active agent and cats product, as: AEO-3 or AEO-7 or AEO-14 or their mixture, but cats product alkyl amine oxide, wherein alkyl carbon number 8-16.

Set forth most preferred embodiment of the present invention below.

Embodiment one: mixed surfactant 12.5%;

AEO-3 4％

AEO-7 5％

AEO-14?2％

Dodecyl amine oxide 1.5% potassium pyrophosphate 6.5% water glass 7% water surplus

Embodiment two: mixed surfactant 12.5% (weight percent, down together)

AEO-7 7％

AEO-14?4％

Dodecyl amine oxide 1.5% potassium pyrophosphate 6%; Water glass 6% water surplus

Embodiment one and two and production method be: earlier potassium pyrophosphate and water glass are added in the gauge water, are stirred to dissolving fully, add tensio-active agent then successively, mix.

Claims

1, a kind of airframe surface cleaning agent, it is characterized in that: it adopts following prescription:

A, mixed surfactant 8-15%
