Problems solved by technology

Since a large number of planes frequently take off and land on the airport every day, some rubber tire wear will remain on the airport runway, making the surface uneven and reducing the friction coefficient of the ground. Not only will it affect the external environment of the entire airport, but it will also reduce the safety of the aircraft during take-off and landing, which may cause accidents
Under the premise of ensuring the safety of the airport runway, physical methods such as high-pressure water washing and steel ball friction are currently used to remove these rubber stains at home and abroad, but such treatment will often destroy the ground flatness of the airport runway, thus affecting safe landing of the plane

Embodiment 1

[0016] Mix 70 parts of orange oil and 1 part of sodium petroleum sulfonate in a container, then add 1 part of N, N'-diphenylthiourea and 1 part of formic acid into the above mixture at room temperature and stir evenly Made into airport pavement rubber dirt cleaning agent.

Embodiment 2

[0018] Mix 75 parts of orange oil and 2 parts of sodium petroleum sulfonate evenly in a container, then add 2.5 parts of N,N'-diphenylthiourea and 1.5 parts of formic acid into the above mixture at room temperature and stir evenly Made into airport pavement rubber dirt cleaning agent.

Embodiment 3

[0020] Mix 80 parts of orange oil and 3 parts of sodium petroleum sulfonate evenly in a container, then add 5 parts of N,N'-diphenylthiourea and 2 parts of formic acid into the above mixture at room temperature and stir evenly Made into airport pavement rubber dirt cleaning agent.

[0021] The surface tension of the airport pavement rubber dirt cleaning agent provided by the 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°C to 60°C, it can be seen that it is an ideal cleaning agent for rubber dirt.

[0022] When utilizing the airport pavement rubber dirt cleaning agent provided by the invention to clean the rubber dirt on the airport pavement, at first adopt the airport joint operation machine to pour the cleaning agent into the tank of the working vehicle, and then spray it on the airport pavement with rubber dirt On the surface, the cleaning operation can be completed after the steps ...

Abstract

The present invention is rubber dirt detergent for airstrip and its preparation process. The rubber dirt detergent consists of mandarin oil 70-80 weight portions, N, N'-diphenyl sulforea 1-5 weight portions, sodium petroleum sulfonate 1-3 weight portions and formic acid 1-2 weight portions. The rubber dirt detergent is compounded with mandarin oil containing limonene over 80 % as the main component and several other surfactants, and has relatively low surface tension for effective elimination of rubber dirt. In addition, the rubber dirt detergent has no corrosion to the surface of the washed matter, no harm to human health and environment, high safety, capacity of being recovered and reused, low cost and simple preparation process.

Description

technical field [0001] The invention relates to an airport pavement rubber dirt cleaning agent and a preparation method thereof, in particular to an airport pavement rubber dirt 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. Since a large number of planes frequently take off and land on the airport every day, some rubber tire wear will remain on the airport runway, making the surface uneven and reducing the friction coefficient of the ground. Not only will it affect the external environment of the entire airport, but it will also reduce the safety of the aircraft during takeoff and landing, thereby causing potential accidents. Under the premise of ensuring the safety of the airport runway, at present, physical methods such as hig...
