Problems solved by technology

In order to ensure the safety of passengers, when the aircraft is parked at the berth, the operator usually needs to carry out normal maintenance. During this process, some oil will drip on the ground of the berth, which will not only affect the external environment of the entire airport, And if these oils just cover the white line on the airport runway, the driver may not be able to get in place accurately when the plane lands because the white line cannot be seen clearly, thus there is a hidden danger of accidents
At present, water-soluble detergent type sol

Example Embodiment

[0017] Example 1:

[0018] Mix 70 parts of orange oil, 10 parts of sodium dodecylbenzene sulfonate, 12 parts of potassium pyrophosphate and 1 part of triethanolamine in a container, and then add 100 parts of deionized water to In the above-mentioned mixed liquid, stir it evenly, and finally cool it to a temperature of 20-25°C to make an airport road surface oil cleaning agent.

Example Embodiment

[0019] Example 2:

[0020] 75 parts of orange oil and 15 parts of sodium dodecylbenzenesulfonate, 18 parts of potassium pyrophosphate, and 2 parts of triethanolamine mixed in a container, and then at a temperature of 40 ~ 60 ℃ of 100 parts of deionized water were added to the In the above-mentioned mixed liquid, stir it evenly, and finally cool it to a temperature of 20-25°C to make an airport road surface oil cleaning agent.

Example Embodiment

[0021] Example 3:

[0022] Mix 80 parts of orange oil with 15 parts of sodium dodecylbenzene sulfonate, 20 parts of potassium pyrophosphate and 3 parts of triethanolamine in a container, and then add 100 parts of deionized water to In the above-mentioned mixed liquid, stir it evenly, and finally cool it to a temperature of 20-25°C to make an airport road surface oil cleaning agent.

[0023] The surface tension of the airport pavement cleaning agent provided by the present invention is 27.23±0.01~25.00mN / m at room temperature, and the solvent viscosity is 2.000~1.550mm 2 / s, and the flash point (closed) is 50 ℃ ~ 60 ℃, it can be seen that the cleaning agent is an ideal substitute for organic solvents.

[0024] When using the airport road surface oil cleaning agent provided by the present invention to clean the oil pollution on the airport road surface, first use the airport joint operation machinery to pour the cleaning agent into the working vehicle tank, and then spray it on the ...

Abstract

This invention discloses a method for preparing a detergent for cleaning airport runways. The detergent is composed of: orange oil 70-80 parts, sodium dodecyl benzenesulfonate 10-15 parts, potassium pyrophosphate 12-20 parts, triethanolamine 1-3 parts and deionized water 100 parts. The detergent uses orange oil with 80% or more limonene as the major component, which is added with multiple surfactants. The detergent has a low surface tension, thus can effectively remove oil stains on airport runways without any corrosion. Since orange oil is a natural extract from orange peels, it has no harm to the environment or human health. Besides, the detergent is not combustive or explosive, thus is safe for usage. Since the volatilization rate of the detergent is low, it can be recovered after cleaning, and recycled after distillation, thus lowering the cost. The method for preparing the detergent is simple.

Description

technical field [0001] The invention relates to an airport pavement oil stain cleaning agent and a preparation method thereof, in particular to an airport pavement oil stain cleaning agent using natural plants as main raw materials and a preparation method thereof. Background technique [0002] With the rapid development of the aviation industry, the number of aircraft is increasing rapidly, and the parking berth area of ​​each airport is also constantly expanding. In order to ensure the safety of passengers, when the aircraft is parked at the berth, the operator usually needs to carry out normal maintenance. During this process, some oil will drip on the ground of the berth, which will not only affect the external environment of the entire airport, And if these oils happen to cover the white lines on the airport runway, the pilot may not be able to get in place accurately when the plane lands because the white lines cannot be seen clearly, which may cause accidents. At pre...
