Problems solved by technology

[0003] Ordinary aircraft can only take off and land on the special runway. The takeoff and landing of the aircraft have strong impact and friction. Commonly used cement concrete runways and asphalt runways are prone to damage and cracks: the maintenance of the airstrip is not only time-consuming , laborious, and costly, it also affects normal shipping, and even affects fighter jets during wartime

Abstract

The invention discloses airplane runway maintenance slurry. The airplane runway maintenance slurry mainly comprises an aqueous fluorocarbon emulsion, nanometer white carbon black, aramid pulp, a penetrating agent and a coupling agent as auxiliary agent. The airplane runway maintenance slurry can be mixed with sand and broken stones and then is used for maintenance of injuries and cracks having different sizes and depth values of cement concrete runways and asphalt runways, and the maintained layer has a long service life, good water resistance and excellent impact resistance.

Description

[0001] technical field [0002] The invention relates to the technical field of fine chemicals, in particular to an aircraft runway maintenance slurry. Background technique [0003] Ordinary aircraft can only take off and land on the special runway. The takeoff and landing of the aircraft have strong impact and friction. Commonly used cement concrete runways and asphalt runways are prone to damage and cracks: the maintenance of the airstrip is not only time-consuming It is costly, laborious, and expensive, and it also affects normal shipping, and even affects fighter jets in wartime. Contents of the invention [0004] The purpose of the present invention is intended to solve the deficiencies in the prior art, provide the airstrip maintenance slurry, and its technical scheme is achieved in this way: [0005] A kind of airstrip maintenance slurry: the mass percentage of its components is: the mass percentage of its components is: 60-70% of water-based fluorocarbon emulsion,...
