Description

Polytetrafluoroethylreal real core hole sealing strip

Technical field

The application belongs to technical field of ship transportation, particularly relates to a kind of polytetrafluoroethylreal real core hole close Strip of paper used for sealing.

Background technology

In macromolecular material, rubber is owing to having good mechanical property and high resilience, elastic modelling quantity The least, therefore it is widely used in anti-vibration article.But on the whole, the machinery of elastomeric material is strong Spending on the low side, wearability is poor, and the frictional resistance produced during motion is big, also has certain in terms of media-resistant Limitation.

On existing freighter, many places need to use rubber part to play the effects such as damping, and rubber used by existing freighter Glue part, causes aliquation to bubble owing to salt fog resistance performance is the best or embrittlement is hardened and aging in surface, is formed Potential safety hazard greatly.

Summary of the invention

It is an object of the invention to provide a kind of polytetrafluoroethylreal real core hole sealing strip, to overcome existing skill Deficiency in art.

For achieving the above object, the present invention provides following technical scheme:

The embodiment of the present application discloses a kind of polytetrafluoroethylreal real core hole sealing strip, including politef Body, described body includes the first noumenon with lower arcuate surface and is formed on described the first noumenon The cross section of side is the second body of inverted trapezoidal, the one side of described second body and the top of described the first noumenon Form a stage portion between face, in the middle part of the end face of described second body recessed be formed bottom one rectangular Groove, the inside of described second body extends along direction and offers the hole of an ellipsoidal cross section.

Preferably, in above-mentioned polytetrafluoroethylreal real core hole sealing strip, the end face of described second body Form zigzag.

Preferably, in above-mentioned polytetrafluoroethylreal real core hole sealing strip, described second body is near it The side of end face is embedded with Magnet.

Preferably, in above-mentioned polytetrafluoroethylreal real core hole sealing strip, described politef body Outside be coated with rubber epidermis.

Preferably, in above-mentioned polytetrafluoroethylreal real core hole sealing strip, described rubber epidermis is with described Glue-line is passed through bonding between politef body.

Compared with prior art, it is an advantage of the current invention that: the present invention uses PTFE stuffing materials, Politef has the most superior chemical stability and low-down coefficient of friction, particularly fills poly- Tetrafluoroethene, owing to adding filler reinforcement material so that it is on the basis of keeping original premium properties, thing Reason mechanical performance is further enhanced so that product hot strength the most significantly exceedes routine >=10Mpa's Index request reaches about 13.4Mpa.

Accompanying drawing explanation

In order to be illustrated more clearly that the embodiment of the present application or technical scheme of the prior art, below will be to reality Execute the required accompanying drawing used in example or description of the prior art to be briefly described, it should be apparent that below, Accompanying drawing in description is only some embodiments described in the application, for those of ordinary skill in the art From the point of view of, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 show the cross section signal of polytetrafluoroethylreal real core hole sealing strip in the specific embodiment of the invention Figure.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out Detailed description, it is clear that described embodiment is only a part of embodiment of the present invention rather than complete The embodiment in portion.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creation Property work on the premise of the every other embodiment that obtained, broadly fall into the scope of protection of the invention.

Shown in ginseng Fig. 1, polytetrafluoroethylreal real core hole sealing strip includes politef body 1, body 1 Including there is the first noumenon 11 of lower arcuate surface and to be formed at the cross section above the first noumenon be inverted trapezoidal The second body 12, form a step between one side 121 and the end face of the first noumenon of the second body 12 Portion 13, recessed in the middle part of the end face of the second body is formed with groove 14 rectangular bottom, the second body Inside extends along direction and offers the hole 15 of an ellipsoidal cross section.

In this technical scheme, body uses polytetrafluoroethylmaterial material, can be greatly improved its mechanical performance And frictional behaviour.

The elastic space of sealing strip in the vertical direction can be improved by hole in the middle part of the second body.

Further, the end face of the second body forms zigzag.

In this technical scheme, by serrated-surface, can improve sealing strip and hatchcover, sealing strip with Sealing between draw-in groove.

Further, the second body is embedded with Magnet near the side of its end face.

In this technical scheme, by arranging Magnet in sealing strip, sealing strip can directly adsorb in cabin On lid or draw-in groove, improve and convenience is installed.

Further, the outside of politef body is coated with rubber epidermis.

Further, bonding by glue-line between rubber epidermis with politef body.

It should be noted that in this article, the relational terms of such as first and second or the like is used merely to One entity or operation are separated with another entity or operating space, and not necessarily requires or imply Relation or the order of any this reality is there is between these entities or operation.And, term " includes ", " comprise " or its any other variant is intended to comprising of nonexcludability, so that include that one is The process of row key element, method, article or equipment not only include those key elements, but also include the brightest Other key elements really listed, or also include intrinsic for this process, method, article or equipment Key element.In the case of there is no more restriction, statement " including ...
