Abstract
The invention discloses a marine watertight door sealing strip. The marine watertight door sealing strip comprises a polytetrafluoroethylene sponge core and skin wrapping the outer side of the polytetrafluoroethylene sponge core. The skin comprises a first skin body, second skin bodies and a third skin body, wherein the first skin body wraps the top surface of the sponge core and is arranged horizontally, the second skin bodies wrap the left side and the right side, opposite to each other, of the sponge core, and the third skin body wraps the bottom surface of the sponge core and is arranged horizontally; the second skin body comprises upper skin bodies which are arranged oppositely and are spaced from each other by a first distance and lower skin bodies which are arranged oppositely and are spaced from each other by a second distance, the first distance is larger than the second distance, and the top ends of the lower skin bodies are connected to the bottom ends of the upper skin bodies through concave arc-shaped grooves. According to the marine watertight door sealing strip, polytetrafluoroethylene sealing materials are adopted, polytetrafluoroethylene has the extremely excellent chemical stability and the extremely-low friction coefficient, and particularly, the sealing strip is filled with polytetrafluoroethylene; due to the fact that the sealing strip is filled with reinforced materials, the physical and mechanical properties of the sealing strip are further improved on the basis that the original excellent performance of the sealing strip is maintained.
Description
Technical field
The application belongs to technical field of ship transportation, particularly relates to a kind of watertight door weather strip peculiar to vessel.
Background technology
In macromolecular material, rubber is owing to having good mechanical property and high resilience, and modulus of elasticity is very little, is therefore widely used in anti-vibration article.But on the whole, the mechanical strength of elastomeric material is on the low side, and abrasion resistance is poor, the frictional resistance produced during motion is large, in media-resistant, also have certain limitation.
On existing freighter, many places need to use rubber part to play the effects such as damping, and existing rubber part for cargo ship, cause aliquation to bubble or harden embrittlement and aging in surface because salt fog resistance performance is not good, form great potential safety hazard.
Summary of the invention
The object of the present invention is to provide a kind of watertight door weather strip peculiar to vessel, to overcome deficiency of the prior art.
For achieving the above object, the invention provides following technical scheme:
The embodiment of the present application discloses a kind of watertight door weather strip peculiar to vessel, comprise polytetrafluoroethylene (PTFE) sponge core, and the epidermis be coated on outside described sponge core, described epidermis comprises and is coated on described sponge core end face and horizontally disposed first epidermis, second epidermis of relative both sides about being coated on described sponge core, and be coated on described sponge core bottom surface and in horizontally disposed 3rd epidermis, described second epidermis comprises and is oppositely arranged and has the epicuticle of the first spacing distance, and be oppositely arranged and there is the lower epidermis of the second spacing distance, described first spacing distance is greater than the second spacing distance, the top of described lower epidermis is connected to the bottom of described epicuticle by recessed deep-slotted chip breaker.
Preferably, in above-mentioned watertight door weather strip peculiar to vessel, the surface of described first epidermis forms zigzag.
Preferably, in above-mentioned watertight door weather strip peculiar to vessel, the soffit of described 3rd epidermis forms zigzag.
Preferably, in above-mentioned watertight door weather strip peculiar to vessel, the material of described epidermis is rubber.
Preferably, in above-mentioned watertight door weather strip peculiar to vessel, the top of described epicuticle is connected by the transition face tilted with the joining place of described first epidermis.
Preferably, in above-mentioned watertight door weather strip peculiar to vessel, described transition face is horizontal by 30 degree of angles.
Preferably, in above-mentioned watertight door weather strip peculiar to vessel, be connected by mucilage layer between described sponge core with described epidermis.
Preferably, in above-mentioned watertight door weather strip peculiar to vessel, the ratio of the height between described first spacing distance, the second spacing distance and epidermis upper and lower surface is 5:4:3.
Preferably, in above-mentioned watertight door weather strip peculiar to vessel, between described first epidermis and the upper surface of sponge core, also magnet is formed with.
Compared with prior art, the invention has the advantages that: the present invention adopts PTFE stuffing materials, polytetrafluoroethylene (PTFE) has extremely superior chemical stability and low-down friction factor, particularly filled polytetrafluoroethylene, owing to adding filler reinforcement material, make it on the basis keeping original premium properties, physical and mechanical properties is further enhanced, and the index request making product hot strength significantly exceed routine >=10Mpa reaches about 13.4Mpa.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present application or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, the accompanying drawing that the following describes is only some embodiments recorded in the application, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Figure 1 shows that the structural representation of watertight door weather strip peculiar to vessel in the specific embodiment of the invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be described in detail the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to the scope of protection of the invention.
Shown in ginseng Fig. 1, watertight door weather strip peculiar to vessel comprises polytetrafluoroethylene (PTFE) sponge core 1, and the epidermis 2 be coated on outside sponge core, epidermis 2 comprises and is coated on sponge core end face and horizontally disposed first epidermis 21, second epidermis 22 of relative both sides about being coated on sponge core, and be coated on sponge core bottom surface and in horizontally disposed 3rd epidermis 23, second epidermis 22 comprises and is oppositely arranged and has the epicuticle 221 of the first spacing distance, and be oppositely arranged and there is the lower epidermis 222 of the second spacing distance, first spacing distance is greater than the second spacing distance, the top of lower epidermis is connected to the bottom of epicuticle by recessed deep-slotted chip breaker 223.
In this technical scheme, sponge core adopts polytetrafluoroethylmaterial material, can greatly improve its mechanical performance.The Side symmetrical of weather strip is recessed is formed with deep-slotted chip breaker, can increase the elastic space of vertical direction.
Further, the surface of the first epidermis forms zigzag, and the soffit of the 3rd epidermis forms zigzag.
