Problems solved by technology

[0003] With the rapid development of industry, the existing adhesive tapes on the market can meet some of people's needs to a certain extent, but the existing adhesive tapes have a relatively single function, generally only have the function of bonding objects, and do not have other functions.
Some items are easily damaged by impact or vibration during transportation, and the existing anti-shock method is generally to place many bubble bags in the box to isolate the objects to be transported from the box, but the bubble bags are generally smaller in size. Large, takes up a lot of space, requires a larger carton, and the cost of paper is now higher; second, the bubble bag itself can be moved. During transportation, the position between the product and the bubble bag often moves, and the bubble bag No longer has the effect of anti-collision
And the breaking strength of the current tape is low, and the two connected objects are broken due to displacement and tension caused by impact or vibration.

Embodiment 1

[0030] see figure 1 , this embodiment discloses a fracture-resistant and shock-proof adhesive tape, comprising a base material layer 2, a first adhesive layer 1, a shock-proof layer 3 and a second adhesive layer 4, the base material layer 2 is a double-layer composite structure, including a layer of foam Cotton layer 21 and a layer of PET film layer 22, specifically, the thickness of the substrate layer 2 is 10um; the two sides of the substrate layer 2 are respectively adhered to the shockproof layer 3 and the first adhesive layer 1, the substrate layer 2 and the shockproof The layers 3 are connected by a high-strength acrylic adhesive. The thickness of the shockproof layer 3 is 10um. The other side of the shockproof layer 3 is provided with a second adhesive layer 4. The thickness is 10um. Specifically in this embodiment, the other side of the second adhesive layer 4 is also attached with a release layer 5, and the release layer 5 is a double-sided release paper, and the two...

Embodiment 2

[0037] see figure 2 , this embodiment is basically the same in structure as Embodiment 1, the difference lies in the thickness settings of each layer, the raw materials of the sandwich layer 33, the first foam material layer 31, the second foam material layer 32, and the double-sided release material. The ratio of the release force between the two sides of the paper is different. In this embodiment, the thickness of the substrate layer 2 is 25um, the thickness of the shockproof layer 3 is 17.5um, and the thickness of the first adhesive layer 1 and the second adhesive layer 4 are both 30um. The thickness of the double-sided release paper 5 is 75um, and the ratio of the release force on both sides is 1:1.5 (inner side: outer side, that is, side A: side B shown in the figure).

[0038] There is a thickness difference of 5um between the first foam material layer 31 and the second foam material layer 32 .

[0039] Preferably, the raw material of the sandwich layer 33 is bamboo f...

Embodiment 3

[0044] see image 3, the present embodiment is basically the same in structure as embodiment one and two, the difference is that the thickness of each layer is set, the raw material of sandwich layer 33, the first foam material layer 31, the second foam material layer 32, and double The ratio of the release force between the two sides of the release paper is different.

[0045] Specifically, the substrate layer 2 has a thickness of 50um, the shockproof layer 3 has a thickness of 25um, the first adhesive layer 1 and the second adhesive layer 4 have a thickness of 50um, and the double-sided release paper 5 The thickness is 100um, and the release force ratio of both sides is 1:2 (inside: outside, that is, side A: side B shown in the figure).

[0046] Preferably, there is a thickness difference of 10 um between the first foam material layer 31 and the second foam material layer 32 .

[0047] Preferably, the raw material of the sandwich layer 33 is ceramic fiber.

[0048] Prefer...

Abstract

The invention discloses a fracture-resistant and vibration-resistant adhesive tape. The fracture-resistant and vibration-resistant adhesive tape comprises a base material layer, a vibration-resistantlayer, a first adhesive layer and a second adhesive layer, wherein the base material layer is of a two-layer compound structure and comprises a foam cotton layer and a PET film layer; the base material and the vibration-resistant layer are adhered to each other through an acrylic adhesive with high adhesion strength; the first adhesion layer and the second adhesive layer are respectively adhered to the outer sides of the base material layer and the vibration-resistant layer. The adhesive tape using the compound base material layer has certain softness, good adhesion property and certain fracture-resistant strength; through the design of the vibration-resistant layer, elastic buffering is provided for places for loading and transporting goods; the adhesive tape is incapable of cockling dueto heat expansion, and is excellent in smoothness and large in adaption temperature difference range from 20 DEG C below zero to 80 DEG C; the safety of transportation of the goods is greatly improved; and the designed adhesive tape has functions of resisting impact and resisting vibration.

Description

technical field [0001] The invention belongs to the technical field of adhesive tapes, in particular to a fracture-resistant and shock-proof adhesive tape. Background technique [0002] Adhesive tape is composed of base material and adhesive. Two or more unconnected objects are connected together by bonding, and a layer of adhesive is coated on the surface. [0003] Along with the rapid development of industry, the adhesive tapes on the existing market have met people's partial needs to a certain extent, but the existing adhesive tapes have a single function, generally only have the function of bonding objects, and do not have other functions. Some items are easily damaged by impact or vibration during transportation, and the existing anti-shock method is generally to place many bubble bags in the box to isolate the objects to be transported from the box, but the bubble bags are generally smaller in size. Large, takes up a lot of space, requires a larger carton, and the cos...
