Problems solved by technology

[0002] Aircraft skin coating is an important functional material to ensure the normal use of aircraft. In addition to meeting specific physical and chemical properties, it also needs to have good anti-contamination and easy-to-clean properties to ensure the cleanliness and maintainability of the aircraft surface. The change of the gloss index of the skin paint from glossy to dull leads to an increase in the surface micro-roughness of the skin paint, and thus the anti-fouling performance of the skin paint is greatly reduced

Embodiment Construction

[0025] A kind of spraying process of fluorocarbon surface coating, it is characterized in that comprising the following steps:

[0026] 1) Cleaning and polishing:

[0027] 1.1) In a clean container, mix 1 part of metal cleaning agent with 20 parts of warm water at 70~80°C in a clean container to prepare an aqueous solution, stir well and set aside. The metal cleaning agent can be 761 metal cleaning agent ;

[0028] 1.2) Dip the prepared metal cleaning agent aqueous solution with a clean natural-color fine flat cloth, and then wipe the marked parts to be processed. Reach the water film continuously for 30s;

[0029] 1.3) Use 320# water abrasive paper to polish the skin surface of the workpiece to be processed evenly, and wipe the polished surface with a clean cloth;

[0030] 2) Spray primer:

[0031] 2.1) Spray a layer of zinc yellow acrylic polyurethane primer evenly on the surface of the cleaned test piece. The zinc yellow acrylic polyurethane is the primer type TB06-9 pr...

Abstract

The invention relates to spraying a process for fluorocarbon surface layer paint, which comprises the following steps of: (1) cleaning and grinding; (2) primer spraying; (3) finish spraying; and (4) fluorocarbon surface layer paint spraying. The aircraft skin processed by the process has strong stain resistance, and the easy cleaning property is obviously improved.

Description

technical field [0001] The invention relates to a spraying process of fluorocarbon surface coating, which is used for the treatment process of the outer surface of aircraft skin. Background technique [0002] Aircraft skin coating is an important functional material to ensure the normal use of aircraft. In addition to meeting specific physical and chemical properties, it also needs to have good anti-contamination and easy-to-clean properties to ensure the cleanliness and ease of maintenance of the aircraft surface. The change of the gloss index of the skin paint from glossy to dull leads to an increase in the surface micro-roughness of the skin paint, and thus the anti-fouling performance of the skin paint is greatly reduced. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a spraying process of fluorocarbon surface coating, the aircraft skin treated by the process has strong anti-pollution and stain resistance, a...
