Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in figure 1, the high-strength energy-absorbing shockproof adhesive tape sequentially comprises an outer layer 10 and an adhesive layer 11, an elastic energy-absorbing layer 12 is arranged between the outer layer 10 and the adhesive layer 11, the upper surface and the lower surface of the energy-absorbing layer 12 are respectively adhered and fixed with the outer layer 10 and the adhesive layer 11, and a strength part 13 is arranged in the energy-absorbing layer 12. In the sticky tape use, adhesion layer 11 adhesion is on the object surface, energy absorbing layer 12 is used for absorbing the energy that vibrations produced, when the object takes place vibrations, the power that vibrations produced makes energy absorbing layer 12 take place deformation, energy absorbing layer 12 that produces deformation absorbs the energy that vibrations produced and restores to the original state under the effect of the resilience of self, thereby absorb the energy that vibrations produced, make the sticky tape break away from the object surface under preventing high frequency vibrations, simultaneously, the displacement of controlling or front and back still can drag the sticky tape produces during vibrations, can make the sticky tape fracture if the sticky tape receives great pulling force, consequently, intensity part 13 produces the displacement pulling force of controlling or front and back when being used for absorbing vibrations, prevent that the sticky tape from breaking.

The strength component 13 comprises a plurality of layers of strength cavities 14 arranged in the energy absorption layer 12, the plurality of layers of strength cavities 14 are arranged at equal intervals along the axial direction of the energy absorption layer 12, and a fiber component 15 is arranged in the strength cavity 14. In this example, because the fibers have strong resilience and strength, several fibers are provided in the strength chamber 14 to absorb the lateral or front-back offset energy generated by the neutralizing shock, preventing the tape from breaking.

As shown in fig. 2, the fiber member 15 includes a plurality of first fiber threads 16 disposed in parallel and at equal intervals, and a plurality of second fiber threads 17 disposed perpendicular to and at equal intervals from the first fiber threads 16, wherein the first fiber threads 16 and the second fiber threads 17 are wound around each other. The first fiber line 16 and the second fiber line 17 are wound in an up-down alternating mode in sequence, the winding mode can increase the friction force between the first fiber line 16 and the second fiber line 17 and increase the connection strength between the first fiber line 16 and the second fiber line 17, the stable structure is ensured, in the process of being stretched, the movement of the first fiber line 16 and the second fiber line 17 can be limited, the strength of the adhesive tape can be enhanced through the winding mode, when the vibration generates left-right or front-back offset force, the offset force is offset through the first fiber line 16 and the second fiber line 17, and the adhesive tape is prevented from being broken.

As shown in fig. 3, the thickness of the strength cavity 14 is 2 times of the thickness of the first fiber line 16 or the second fiber line 17, the ends of the first fiber line 16 and the second fiber line 17 are respectively fixed on the two side end walls of the strength cavity 14, and the first fiber line 16 and the second fiber line 17 are both fixedly connected with the upper end wall and the lower end wall of the strength cavity 14. The first fiber line 16 and the second fiber line 17 are simultaneously fixed with each end wall of the fixed strength cavity 14, so that the strength of the energy absorption layer 12 is increased, the maximum offset force generated by the vibration in the energy absorption layer 12 can be increased, the adhesive tape is prevented from being broken, and the product quality is improved.

The energy absorption layer 12 is a polyurethane foam layer or acrylic acid foam. The energy absorption layer 12 is composed of a foam layer made of foam cotton, the foam layer is environment-friendly, impact-resistant, acid-base-resistant, good in shockproof buffering effect, and secondly, the energy absorption layer 12 is connected with the outer layer 10 and the adhesion layer 11 through an adhesive, so that the tensile resistance can be increased, and deformation and size change are not easy to occur.

The first fiber line 16 and the second fiber line 17 are respectively formed by spirally winding a plurality of fiber thin lines. The plurality of fiber threads are bundled into a bundle, and the end of the bundle of fiber threads is rotated toward the center line thereof and extended to the other end, thereby increasing the strength of the first fiber thread 16 and the second fiber thread 17.

The fine fiber is PTT fiber or polyester fiber. The fiber has good softness and elastic recovery, excellent crease resistance and dimensional stability, weather resistance, especially PTT fiber, excellent characteristics, increased strength of the adhesive tape, and prevention of the adhesive tape from cracking.

The axis of the strength cavity 14 coincides with the axis of the energy absorbing layer 12. When the vibration generates a left-right or front-back offset force, the offset force is transmitted to the strength cavity 14 through the energy absorption layer 12, the axis of the strength cavity 14 coincides with the axis of the energy absorption layer 12, so that the force borne by the strength cavity 14 can be uniformly distributed on the peripheral end walls of the strength cavity 14 as much as possible, the breakage of a certain part caused by the overlarge force at the certain part is prevented, the stability of the adhesive tape is improved, the force borne by the strength cavity 14 is uniformly distributed on the peripheral end walls of the strength cavity 14, the force borne by the peripheral end walls of the strength cavity 14 is smaller, and the maximum pulling force which can be borne by the adhesive tape and is generated by the vibration is indirectly increased.

Because the area of contact between the upper and lower end walls of fibre line and intensity chamber 14 is greater than the area of contact between the end wall about fibre line and intensity chamber 14, the power that makes the upper and lower end wall of intensity chamber 14 can bear is greater than the power that the end wall can bear about intensity chamber 14, consequently in this example, increase the foam thickness in the energy absorbing layer 12 of the end wall side about intensity chamber 14, when vibrations, the foam of the end wall side about intensity chamber 14 can absorb more energy, thereby the end wall receives less power about making intensity chamber 14, the stability of sticky tape is improved.

The thickness of the energy absorbing layer 12 is 1-2 times the thickness of the outer layer 10 and the adhesive layer 11. The energy absorption of the adhesive tape is increased, and the strength and the stability of the adhesive tape are improved.
