Accompanying drawing herein is merged in specification and constitutes the part of this specification, it is shown that meet this
The embodiment of application, and for explaining the principle of the application together with specification.
Detailed description of the invention
Below by specific embodiment and combine accompanying drawing the application is described in further detail.Literary composition
Described in "front", "rear", "left", "right", " on ", D score all with the stretchable adhesive tape in accompanying drawing and
The laying state of stretchable tape product is reference.
As it is shown in figure 1, the application embodiment provides a kind of stretchable adhesive tape, including stretching
Skeleton 10 and adhesive phase 12.Wherein, adhesive phase 12 is along the length direction of stretchable adhesive tape
Extending, for being adhesively fixed with other object, stretching skeleton 10 is then embedded into adhesive phase 12
Inside, as the skeleton of stretchable adhesive tape, be used for preventing stretchable adhesive tape from occurring in drawing process
Fracture.
Stretching skeleton 10 extends along the length direction of stretchable adhesive tape, if stretching skeleton 10 includes the Heavenly Stems and Earthly Branches
Section 100 and bent node 102, adjacent two sections 100 are connected by bent node 102.This
In a little sections 100, at least need the bearing of trend of a section 100 for a part and stretchable adhesive tape
Length direction is an angle, the most non-parallel state.So, when whole stretchable adhesive tape is by edge
During the pulling force of length direction, because the existence of angle, with the section that these and length direction exist angle
100 bent node 102 being connected be subject to the active force of different directions and bend, rotation etc.
Deformation so that the angle of angle tends to reducing, and makes the bearing of trend of these sections 100 the most simultaneously
Reach unanimity with the length direction of stretchable adhesive tape, in turn result in stretching skeleton 10 at length direction
The increase of size.
As long as stretching skeleton 10 can carry out deformation, just will not be pulled off, and without by improving base
The mode of body thickness prevents from rupturing in drawing process.
As shown in Figure 2 and Figure 4, another embodiment of the application also provides a kind of stretchable adhesive tape,
Including stretching skeleton 10, adhesive phase 12 and base layer 14.Base layer 14 and adhesive phase
12 all extend along the length direction of stretchable adhesive tape, and adhesive phase 12 covers base layer 14 and is perpendicular to
The surface of the thickness direction of stretchable adhesive tape, stretching skeleton 10 embeds in base layer 14.The present embodiment
In stretching skeleton 10 structure identical with a upper embodiment.But due to the existence of base layer 14, this
Stretchable adhesive tape in embodiment can possess higher hot strength.Simultaneously with base layer 14 for carrying
Body, adhesive phase 12 can be placed only in base layer and be perpendicular to its of thickness direction of stretchable adhesive tape
In a side surface, constitute the stretchable adhesive tape of one side.And a upper embodiment is due to directly will stretching skeleton 10
It is embedded into the inside of adhesive phase 12, therefore can have in the both side surface being perpendicular to thickness direction simultaneously
Standby adhesive, is merely able to form two-sided stretchable adhesive tape (seeing Fig. 2 and Fig. 4).
In the above two embodiments, in order to meet the stretch range demand of stretchable adhesive tape, typically need
Skeleton 10 to be stretched reduces process by angle, and the size at length direction at least can increase 1.5
More than Bei.
In order to make stretching skeleton 10 take the size of less thickness direction, on stretching skeleton 10 as far as possible
Each section 100 the most all extend along the thickness direction being perpendicular to stretchable adhesive tape, namely edge
The length direction of stretchable adhesive tape and plane that width is constituted extends.In the two
In embodiment, stretching skeleton 10 can include some fiber filaments, a section 100 and bending joint
Point 102 is distributed on every fiber filament so that these fiber filaments all can prolong under a stretching force
The size of long length direction.Further, every fiber filament reduces process by angle, at length direction
Size increase amplitude the most identical.
These fiber filaments each other can be separate, does not occur any actual contact (such as Fig. 4
Shown in Fig. 5).But can also be connected with each other at bent node 102 each other, constitute the most firm,
Complicated structure.The most preferred a kind of mode is the formation water chestnut that is connected to each other by these fiber filaments
Shape network (as shown in Figures 2 and 3), this structure can significantly improve stretching skeleton 10
Structural strength, more efficiently prevent situation about being pulled off from occurring.
For general stretchable adhesive tape, the diameter of fiber filament in 20 μm-50 μ m, its
Fracture tensile strength is greater than 5N, and elongation at break is less than 15%.Namely preferably with
Toughness is relatively large, the fiber filament that hot strength is higher simultaneously.This fiber filament easily bends,
And self-strength is higher, applies and hot strength can be greatly improved in stretchable adhesive tape.In order to full
Can stretch tape length and stretching demand, the continuous length of fiber filament can be at 500m-
Between 4000m, use monofilament or multifilament.
For the selection of fiber filament kind, at least one in artificial regeneration fiber or synthetic fibers.
Wherein, artificial regeneration fiber is selected from viscose rayon, nitrate fiber or acetate fiber；Synthetic fibers
Again selected from PETP fiber, vinylon, polyacrylonitrile fibre, gather
Olefin(e) fibre, vinal, polyvinyl chloride fibre or Fypro.For Fypro,
Such as nylon-66, polyamide fibre-1010 or polyamide fibre-6 etc. all can use.
Another embodiment of the application additionally provides a kind of stretchable tape product, this stretchable adhesive tape system
Product include the stretchable adhesive tape in release liners 2 and previous embodiment.At least one side of release liners 2 is
Pasta 20, uses this pasta 20 to cover stretchable adhesive tape and is perpendicular to a side surface of thickness direction.Right
In the stretchable adhesive tape of one side, it is only necessary to use the release liners 2 of one side pasta, pasta 20 is covered viscous
In mixture layer 12, and for two-sided stretchable adhesive tape, then need to use and two-sided be the release of pasta
Paper 2, covers the adhesive phase 12 in the wherein side of stretchable adhesive tape by the side pasta of release liners 2
Upper (seeing Fig. 2 and Fig. 4), then coiling is deposited.In the case of Ping Chang, gluing on stretchable adhesive tape
Mixture layer 12 is covered by release liners 2, plays protection and is easy to the purpose taken；When needs make
During with this stretchable tape product, release liners 2 can be removed by stripping on stretchable adhesive tape, expose
The adhesive phase 12 of stretchable adhesive tape, carries out bonding with bonded object.
Stretchable adhesive tape provided herein and stretchable tape product can not increase thickness
In the case of be effectively ensured and do not rupture in drawing process.
The foregoing is only the preferred embodiment of the application, be not limited to the application, for
For those skilled in the art, the application can have various modifications and variations.All essences in the application
Within god and principle, any modification, equivalent substitution and improvement etc. made, should be included in the application
Protection domain within.
