Description
Technical field
The invention belongs to field of airplane structure, and in particular to a kind of electromagnetic protection technology of airplane hatch cover.
Background technology
Lid on aircraft is below deck equipment detection, change and maintenance indispensable passage, be indispensable removable of aircraft
Structure is unloaded, should typically have the functions such as watertightness, quick dismounting property and electromagnetic protection performance.In order to ensure lid watertightness and
The lap-joint of dismounting agility, lid and mouth frame, lid border typically all leave enough gaps, and coat waterproof in gap location
Lid, is then pressed on mouthful frame by glue by screw or quick-detachable lock.But because marine glue is electromagnetic wave transparent material, does not possess electromagnetism and prevent
Protective function, electromagnetic wave can be coupled into interior of aircraft by gap, and the electronic equipment around lid is impacted.
At present, the existing method of airplane hatch cover electromagnetic protection is coated and led in the lap-joint of lid and mouth frame, lid border
Electric glue, makes lid have certain electromagnetic protection ability.But the hardness of conducting resinl is big, compress variation is small after colloid solidification,
To lid and the compensatory difference in mouth frame gap, thus water resistance is also poor.Simultaneously as the coating processes of conducting resinl are complicated,
In outfield in use, replacing maintainability is poor.
The content of the invention
The present invention proposes the electromagnetic protection method and conductive seal bar of a kind of airplane hatch cover, can not only meet the watertight of lid
Property require, and disclosure satisfy that electromagnetic protection requirement.
A kind of electromagnetic protection method of airplane hatch cover, comprising lid, mouth frame and conductive seal bar, conductive seal bar is bonded in
On mouth frame, it is characterised in that described conductive seal adhesive tape is a composite seal bar, is formed by the usual silicone rubber of side
Band and the buffer zone formed by conductive rubber of opposite side be attached in the enhancing tissue layer of bottom and constitute side by side, lid
During closing, lid compresses conductive seal adhesive tape, by the usual silicone rubber band of conductive seal bar realize lid watertight and
It is airtight to require, the electromagnetic protection requirement of lid is realized by the conductive rubber buffer zone of conductive seal bar.
The advantage of the invention is that：Sealed by usual silicone rubber band and the compound tooth form of conductive rubber buffer zone
Bar, realizes the water-stop function and electromagnetic protection function of lid；Conductive seal bar is connected on mouthful frame by bonding agent, realized
Being rapidly assembled and disassembled of conductive seal bar, and convenient use safeguards.
The present invention is described in further detail below in conjunction with specific embodiments and the drawings.

Embodiment
As illustrated, a kind of electromagnetic protection method of airplane hatch cover of the invention, includes lid 1, mouth frame 2 and conductive seal bar
3, it is characterised in that the conductive seal bar 3 is bonded on mouthful frame 2, when lid 1 is closed, lid is compressed by screw 4, so that
Conductive seal bar 3 is compressed, it is ensured that the watertightness requirement and electromagnetic protection requirement of lid 1.Described conductive seal bar 3 is one
With sealing tooth composite seal bar, by side usual silicone rubber band 5 and opposite side conductive rubber buffer zone 6 simultaneously
Row are attached in the enhancing tissue layer 7 of bottom and constituted, and described usual silicone rubber band 5, is to be mixed into reinforcement by polysiloxanes
Tentatively vulcanization is formed under certain temperature and pressure for filler and other additives, with high resiliency, high life, environmental suitability
Good the features such as, described conductive rubber buffer zone 6 is to add metal-powder, coupling agent etc. by a certain percentage in elastomeric material
Mixing is formed, the characteristics of with electromagnetic protection performance, but the hardness of conductive rubber is big compared with usual silicone rubber, and both use docking sides
Formula composite sulfuration shapes.Elastomeric usual silicone rubber band 5 ensures the watertightness of lid, and conductive rubber buffer zone 6 ensures
The electromagnetic protection performance of lid, the enhancing tissue layer 7 of bottom improves the tearing toughness of conductive seal bar.Usual silicone rubber is sealed
With 5 using the structure type that high tooth 8 and deep chute 9 are designed is sealed, deep chute 9 ensures that the high tooth 8 of sealing has enough deformation spaces,
And conductive rubber buffer zone 6 is larger due to hardness, the decrement of the relatively common silastic structure of decrement is small, therefore uses and seal low
The structure type that tooth 10 and shallow chute 11 are designed.That is, the difference in height for sealing high tooth 8 and deep chute 9 is more than the low tooth of sealing
10 and the difference in height of shallow chute 11, the height for sealing high tooth 8 is more than the height for sealing low tooth 10.It is conductive close when lid 1 is closed
Strip of paper used for sealing 3 seals high tooth 8 and seals low tooth 10 and compressed, the depth that side is squeezed into respectively is slipped under the squeezing action of lid 1
In groove 9 and shallow chute 11, it is ensured that sealing tooth is completely attached to lid 1, so as to ensure the water-stop function and electromagnetic protection of lid 1
Function.
The compression deformation rate of rubber controls most important, the compression deformation rate of usual silicone rubber band 5 in implementation process
Scope is 16%~56%, and conductive rubber buffer zone 6 has the compression deformation rate scope to be 8%~26%.In addition, the number of sealing tooth
Amount need to be adjusted according to the width of mouth frame 2, and the height of sealing tooth need to be carried out according to the gap length between lid 1 and mouth frame 2
Adjustment, it is important to ensure the water-tight function and electromagnetic protection function of conductive seal bar 3.Using airplane equipment cabin safeguard lid as
Example, the gap between lid and mouth frame is 1.5mm, and the height of the high tooth 8 of sealing of conductive seal bar design is 2.2mm, deep chute 9
Height 1.4mm (i.e. deep chute depth is 0.8mm), the height for sealing low tooth 10 is 1.85mm, and the height of shallow chute 11 is
1.5mm (i.e. shallow chute depth is 0.35mm).
The present invention realizes lid by usual silicone rubber band 5 and the compound tooth form sealing strip of conductive rubber buffer zone 6
1 water-stop function and electromagnetic protection function；Meanwhile, conductive seal bar 3 is connected on the mouth frame 2 of aircraft by bonding agent,
Being rapidly assembled and disassembled for conductive seal bar 3 is realized, and convenient use is safeguarded.
The above-mentioned conductive seal bar for airplane hatch cover sealing, can be used for other needs to seal and electromagnetic protection
Sealing place.
Above disclosed is only the preferred embodiment of the present invention, it is impossible to the interest field of the present invention is limited with this.
Therefore shape, height and the quantity of the equivalent variations made according to patent of the present invention, such as change sealing tooth, still fall within institute of the present invention
The scope covered.
