The aviation cover plate gasket has the advantages that the sealing performance and the corrosion resistance are good, when the aviation cover plate gasket is used, the metal composite material gasket is directly installed, aviation aluminum mesh and fluorine-silicon resin are compressed simultaneously after cover plate screws are locked, so that the aviation aluminum mesh and the fluorine-silicon resin are attached to a cover plate more tightly, the sealing performance is guaranteed, meanwhile, protrusions on the surface of the aviation aluminum mesh can be in contact with the cover plate to provide a good conductive path, and the fluorine-silicon resin tightly combined with the aviation aluminum mesh and the gasket can protect the fluorine-silicon resin, so that the service life is prolonged.
Description
Technical Field
The utility model relates to the technical field of composite materials, in particular to a metal composite material gasket for EMI shielding of an aircraft cover plate.
Background
Gaskets are mechanical seals that fill the space between two or more mating surfaces, typically to prevent leakage from the connected objects or into the engaged object when compressed.
Aviation apron gasket in the existing market can only provide electric conductive property, need collocation seal gasket to use if want to have the leakproofness, and aviation apron gasket's corrosion resisting capability is poor to lead to aviation apron gasket's life cycle short, thereby reduced aviation apron gasket's practicality, in order to solve above-mentioned problem, a metal composite gasket for aircraft apron EMI shielding, urgent need to be developed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a metal composite gasket for shielding EMI (electro-magnetic interference) of an airplane cover plate, which has the advantages of good sealing performance and good corrosion resistance, and solves the problems that an aviation cover plate gasket in the current market can only provide conductive performance, if the sealing performance is required to be matched with a sealing gasket, and the corrosion resistance of the aviation cover plate gasket is poor, so that the service cycle of the aviation cover plate gasket is short, and the practicability of the aviation cover plate gasket is reduced.
In order to achieve the purpose, the utility model provides the following technical scheme: a metal composite gasket for EMI shielding of aircraft cover plates comprises a gasket, wherein a first composite resin is bonded on two sides of the gasket, and a second composite resin is bonded on one side of the first composite resin;
the top surface of the gasket is provided with a through hole in a penetrating way, and aviation lubricating grease is bonded on the inner wall of the through hole;
the outer wall of the gasket is provided with an aviation aluminum net and fluorine silicon resin.
Preferably, the surface of the aviation aluminum net is provided with a bulge.
Preferably, the fluorosilicone resin is bonded with the gasket and the aviation aluminum net through a composite compression molding process.
Preferably, the first composite resin has the same thickness as the gasket, and the second composite resin has a thickness of one half of the thickness of the first composite resin.
Compared with the prior art, the utility model has the following beneficial effects:
the aviation cover plate gasket has the functions of good sealing performance and good corrosion resistance, when in use, the metal composite gasket is directly installed, after the cover plate screw is locked, the aviation aluminum net and the fluorine-silicon resin are simultaneously compressed, so that the aviation aluminum net and the fluorine-silicon resin are more tightly attached to the cover plate, the sealing performance is ensured, meanwhile, the protrusion on the surface of the aviation aluminum net can be contacted with the cover plate to provide a good conductive path, the fluorine-silicon resin tightly combined with the aviation aluminum net and the gasket can protect the fluorine-silicon resin, so that the service life is prolonged, the corrosion resistance of two sides of the gasket is ensured by the matched use of the first composite resin and the second composite resin, meanwhile, the strength of a fastening part with the screw is ensured while the corrosion resistance of the gasket is increased, so that the problem that the aviation cover plate gasket in the current market can only provide the conductive performance is solved, and if the sealing performance is required to be matched with a sealing gasket, and the corrosion resistance of the aviation cover plate gasket is poor, so that the service cycle of the aviation cover plate gasket is short, and the practicability of the aviation cover plate gasket is reduced.
