Into.In order to prevent into water, the technique hole on all joints and both ends rib is both needed to encapsulation process.In assembling, in order to keep away
Exempt from, because the technique that rivets or be spirally connected produces destruction to sandwich, to protect technique hole in the puncture site of sandwich
Shield, prevent that honeycomb or foam inside form ponding caused by structure destroys generation rain leakage or steam colds and heat succeed each other, and cause to press from both sides
Rotating fields local area unsticking, glue-joint strength reduce, and ultimately result in the damage of structural member.
Utility model content
The purpose of this utility model：In order to solve the above problems, the utility model proposes one kind to have wear-resistant anti-corrosive properties
Can sandwich, by one layer of protection materials of sandwich edge wrap, making honeycomb core or foam core not by rainwater or
Moisture attacks, and can effectively prevent sandwich from potential corrosion occurs and reduces to wear caused by vibration with other metal materials.
The technical solution of the utility model：A kind of sandwich with wear-resistant antiseptic property, including：First panel,
Two panels and the honeycomb core being arranged between first panel and second panel；
The upper bottom surface of the honeycomb core respectively by stick impregnate window screening respectively with the first panel and the second face
The inner surface of plate bonds；
Protection band wraps up the marginal position of first panel and second panel, and honeycomb core is together wrapped up.
Preferably, protection band fexible film band made of inert polymer material.
Preferably, the inner surface of the protection band is sticking veneer, and the sticking veneer, which is provided with, pastes agent.
Preferably, the metal fastenings installation region of the sticking area of the protection band and the sandwich, which coordinates, sets
Put, the metal fastenings installation region is in the range of the sticking area of the protection band.
Preferably, the fexible film band is made up of fluoropolymer.
The beneficial effect of technical solutions of the utility model：A kind of interlayer knot with wear-resistant antiseptic property of the utility model
Structure, there is advantages below：
1) edge of sandwich is played a protective role；
2) erosion of rainwater, steam and other liquid to honeycomb in sandwich or foam is prevented；
3) prevent that composite, metal material from contacting with each other caused potential corrosion；
4) reduce and rub, wear caused by vibration；
5) easy for installation, simple, it is easy to change.
Brief description of the drawings
Fig. 1 is a kind of structural representation of a preferred embodiment of the sandwich with wear-resistant antiseptic property of the utility model
Figure；
Fig. 2 is the honeycomb core scheme of installation of embodiment illustrated in fig. 1；
Fig. 3 is the stickup schematic diagram of the protection band of embodiment illustrated in fig. 1；
Wherein, 1- first panels, 2- second panels, 3- honeycomb cores, 4- protection bands, 5- window screenings.
Embodiment
To make the purpose, technical scheme and advantage that the utility model is implemented clearer, below in conjunction with the utility model
Accompanying drawing in embodiment, the technical scheme in the embodiment of the utility model is further described in more detail.In the accompanying drawings, from beginning
Same or similar element is represented to same or similar label eventually or there is the element of same or like function.Described reality
It is the utility model part of the embodiment to apply example, rather than whole embodiments.Below with reference to the embodiment of accompanying drawing description
It is exemplary, it is intended to for explaining the utility model, and it is not intended that to limitation of the present utility model.It is new based on this practicality
Embodiment in type, the every other implementation that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example, belong to the scope of the utility model protection.Embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.
In description of the present utility model, it is to be understood that term " " center ", " longitudinal direction ", " transverse direction ", "front", "rear",
The orientation or position relationship of the instruction such as "left", "right", " vertical ", " level ", " top ", " bottom " " interior ", " outer " is based on accompanying drawing institutes
The orientation or position relationship shown, it is for only for ease of description the utility model and simplifies description, rather than indicates or imply and be signified
Device or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to this practicality
The limitation of novel protected scope.
Embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, refers to Fig. 1 to Fig. 3；
A kind of sandwich with wear-resistant antiseptic property, including：First panel 1, second panel 2 and it is arranged on the first face
Honeycomb core 3 between plate and second panel；
The window screening 5 that the upper bottom surface of honeycomb core 3 is impregnated by stick respectively respectively with first panel 1 and second panel 2
Inner surface bonds；
The fexible film band made of inert polymer material of protection band 4, the inner surface of protection band 4 is sticking veneer, is pasted
Face, which is provided with, pastes agent.
The sticking area of protection band 4 and the metal fastenings installation region of sandwich are equipped with, metal fastenings peace
Region is filled in the range of the sticking area of protection band 4, because protection band 4 is a kind of inert nonmetallic materials, avoids folder
When Rotating fields contact with other parts, when will not produce potential corrosion, while be fastened using rivet or bolt, isolation can be also played
