Description

A multi-functional box for repairing microwave absorbing coatings at external factories Technical Field

[0001] This utility model belongs to the field of radar absorbing coating repair technology, and relates to a multi-functional box for repairing radar absorbing coatings in external factories. Background Technology

[0002] In long-term and complex service environments, the exposed coatings of stealth aircraft are subjected to various stresses, including environmental and mechanical stresses. These stresses acting on the coating may cause problems such as discoloration, chalking, blistering, and cracking, leading to reduced coating adhesion and subsequent peeling, ultimately resulting in a deterioration of stealth performance. In severe cases, it may even cause the aircraft to completely lose its stealth capability.

[0003] For failed microwave absorbing coatings, in-situ repair methods are generally used for repair. Specifically, in an outdoor environment, the affected area needs to undergo a series of procedures, including localized paint removal, substrate surface treatment, painting, curing, appearance finishing, and inspection, to repair the problematic area. Given the complexity of outdoor repair conditions, the procedures involved encompass coating removal, substrate sanding, microwave absorbing coating application, coating curing, and coating finishing.

[0004] To ensure the integrity of the coating, tools specifically designed for stealth coating repair must be used. The professional tools required for field repair of radar-absorbing coatings are diverse and numerous. For example, protective equipment for workers includes protective gloves, safety glasses, protective clothing, and protective tape; the coating removal and substrate sanding steps require tools such as scrapers, utility knives, rubber mallets, electric grinders, portable vacuum cleaners, cleaning agents, lint-free cloths, and sandpaper; currently, radar-absorbing coatings are mainly repaired through compressed air spraying, putty filling, and patch application, requiring equipment such as spray guns, paints, putty, patches, adhesives, scrapers, dispersing scoops, and spray gun cleaning tools; the coating curing stage requires a heat gun; and the coating finishing stage uses items such as utility knives, scrapers, sandpaper, and protective tape. In summary, a professional coating repair toolkit is indispensable. Furthermore, during field coating repair work, the short interval between aircraft landing and takeoff often results in insufficient curing time for the coating. Due to their inherent properties, some repaired coatings or resin adhesives cannot cure quickly at room temperature. They require heating and extended curing times to ensure complete curing. If the coating fails to cure completely, it is highly susceptible to peeling, leading to reduced stealth performance and posing a significant risk. In coating repair processes, field repair scenarios may be encountered. In such cases, equipping the equipment with a portable external power source can further expand the applicability of coating repair technology.

[0005] In view of the above, this utility model is hereby proposed. Summary of the Invention
