Abstract

The invention discloses a graphene stealth skin primer as well as a preparation method and application thereof, belongs to the technical field of corrosion prevention, and solves the technical problems that an existing aircraft surface skin coating is liable to corrode, low in hardness, poor in toughness, poor in temperature change resistance and liable to generate cracks, and a problem that an aircraft shields radar waves. According to the graphene stealth skin primer disclosed by the invention, bisphenol A epoxy resin in the components can provide excellent salt fog resistance and adhesive force for a coating, graphene modified dispersion liquid greatly improves the hardness, impact resistance, flexibility and salt fog resistance of a paint film, and meanwhile, good static conductivity of the paint film is provided; titanium dioxide with good weather resistance is adopted as coloring pigment, and good covering power is provided for a paint film; the service life of an aircraft skin material can be prolonged, an aircraft is endowed with electromagnetic wave absorption performance, and the material is also applicable to other aircrafts and the like with shielding requirements.

Description

technical field [0001] The invention belongs to the technical field of anticorrosion, and in particular relates to a graphene stealth skin primer and a preparation method and application thereof. Background technique [0002] Aircraft skin coating is not only the exterior decoration material of the aircraft, but also an important material for the aircraft structure to prolong the service life of the aircraft and ensure safe flight. During the flight, the aircraft will encounter high-altitude sudden cooling and sudden heating temperature changes and the strong impact of high-speed airflow. The aircraft may encounter harsh environments such as sand and stone collisions during take-off or landing. Traditional aircraft skin paints generally have good outdoor weather resistance and certain corrosion resistance, but they generally have the disadvantage of poor impact resistance of the paint film in low temperature environments, which leads to the occurrence of corrosion when it en...
