Abstract
The present invention provides the sealing strip of a kind of composite construction, including the weatherstrip body that cross section is " E " shape, being provided with cavity inside weatherstrip body, the edge of cavity has sawtooth, it is filled with expanded material in cavity, in expanded material, be provided with the skeleton of four bar shaped carbon fibre composite materials.The present invention is by filling-foam material in weatherstrip body, not only improve the elasticity of sealing strip, simultaneously cost-effective, the sawtooth of cavity can prevent expanded material from misplacing with weatherstrip body, and the bonding jumper bottom the skeleton of the carbon fibre composite material in expanded material and cavity can be strengthened the intensity of sealing strip, prevent the generation of phenomenon of rupture, in addition, flexible silicon glue-line can further enhance the elasticity of sealing strip, improves the quality of sealing strip, extends the service life of sealing strip.It favorable sealing property of the present invention, simple in construction, cheap, reliable and stable is easily achieved again.
Description
Technical field
The present invention relates to technical field of sealing technology, in particular it relates to the sealing strip of a kind of composite construction.
Background technology
In the equipment such as various machineries, chemical industry, metallurgy, in order to prevent the seepage of liquids and gases, need
Equipment interface, and the suitable effective sealing of local offer, to this end, typically use sealing strip, sealing gasket
Deng as most basic sealing original paper.Owing to sealing strip usually works under rugged environment, so having to
Asking sealing strip to have anticorrosive, anti-high and low-temp, the outstanding sealing property such as wear-resistant, guarantee seals effect
Fruit is good for a long time and reliable and stable.
Sealing strip of the prior art typically uses the single constructive layer sealing strip that solids elastomeric material is made, generally
The elasticity showing as sealing strip is poor, phenomenon of rupture easily occurs simultaneously.For the problems referred to above, art technology
Personnel need the sealing strip providing a kind of compound structure for new residence badly.
Content of the invention
The technical problem to be solved in the present invention is: provides the sealing strip of a kind of composite construction, not only improves and seal
The elasticity of bar, prevents sealing strip from rupturing simultaneously.
The technical solution adopted for the present invention to solve the technical problems is: provide the sealing strip of a kind of composite construction,
Including the weatherstrip body that cross section is " E " shape, inside described weatherstrip body, be provided with cavity, described in
The edge of cavity has sawtooth, is filled with expanded material, is provided with four in described expanded material in described cavity
The skeleton of root bar shaped carbon fibre composite material.
Preferably, the bottom of described cavity is provided with a bonding jumper.
Preferably, the flexible layer of silica gel of lateral wall overlying of described weatherstrip body.
Preferably, described sealing strip is structure as a whole, between described flexible silicon glue-line and described weatherstrip body
Bondd by sulfuration.
Preferably, the sawtooth of described cavity is triangular sawtooth.
Preferably, the sawtooth of described cavity is rectangular saw-tooth.
Preferably, the material of described weatherstrip body is rubber.
The invention provides the sealing strip of a kind of composite construction, by filling-foam material in weatherstrip body,
Not only improving the elasticity of sealing strip, simultaneously cost-effective, the sawtooth of cavity can prevent expanded material and sealing
Bar body misplaces, and the bonding jumper bottom the skeleton of the carbon fibre composite material in expanded material and cavity can
Strengthen the intensity of sealing strip, prevent the generation of phenomenon of rupture, additionally, flexible silicon glue-line can further enhance
The elasticity of sealing strip, improves the quality of sealing strip, extends the service life of sealing strip.Sealing property of the present invention
Well, simple in construction, cheap, reliable and stable be easily achieved again.
Brief description
For the technical scheme being illustrated more clearly that in the embodiment of the present invention, below will be to required in embodiment
The accompanying drawing using is briefly described, it should be apparent that, the accompanying drawing in describing below is only the one of the present invention

Other accompanying drawing can be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the sealing strip preferred embodiment of the composite construction of the present invention.
[reference in figure]:
10. weatherstrip body, 20. cavities, 30. sawtooth, 40. expanded materials, 50. skeletons, 60.
Bonding jumper.
Detailed description of the invention
For making present disclosure more clear understandable, below in conjunction with Figure of description, to present disclosure
It is described further.Certainly the invention is not limited in this specific embodiment, those skilled in the art institute
Known to general replacement be also covered by within the scope of the present invention.Secondly, the present invention utilizes schematic diagram to carry out
Detailed statement, when describing present example in detail, for convenience of description, schematic diagram is not according to general ratio
Partial enlargement, should be in this, as limitation of the invention.
Above and other technical characteristic and beneficial effect, by conjunction with the embodiments and the composite junction to the present invention for the accompanying drawing 1
The sealing strip of structure is described in detail.As it is shown in figure 1, Fig. 1 to be the sealing strip of the composite construction of the present invention preferred
The structural representation of embodiment.
As it is shown in figure 1, the present invention provides the sealing strip of a kind of composite construction, including cross section is " E " shape
Weatherstrip body 10, weatherstrip body 10 is internal is provided with cavity 20, and the edge of cavity 20 has sawtooth 30,
It is filled with expanded material 40 in cavity 20, in expanded material 40, be provided with four bar shaped carbon fibre composite materials
Skeleton 50.
For preventing the generation of sealing strip phenomenon of rupture, the bottom of cavity 20 can be provided with a bonding jumper 60.
For improving the elasticity of sealing strip further, the flexible layer of silica gel of lateral wall overlying of weatherstrip body 10,
Being bondd by sulfuration between flexible silicon glue-line and weatherstrip body 10, sealing strip is structure as a whole.Additionally, it is close
The material of strip of paper used for sealing body 10 is preferably rubber.
For preventing expanded material 40 from misplacing with weatherstrip body 10, the sawtooth 30 of cavity 20 is preferably triangle
