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 , the present embodiment discloses a reinforced anti-vibration adhesive tape, comprising a base material layer 3, a first adhesive layer 1, a first anti-vibration layer 2, a second anti-vibration layer 4 and a second adhesive layer 5, the base material layer 3 It is a double-layer composite structure, including one layer of foam layer 31 and one layer of PET film layer 32. Specifically, the thickness of the base material layer 3 is 10um; The second anti-vibration layer 4, the acrylic adhesive with high bonding strength can be used as the adhesive, the thickness of the first anti-vibration layer 2 and the second anti-vibration layer 4 is 10um, and the other side of the first anti-vibration layer 2 is bonded to the first anti-vibration layer. Adhesive layer 1, the other side of the second anti-shock layer 4 adheres to the second adhesive layer 2, the thickness of the first adhesive layer 1 and the second adhesive layer 5 are both 10um. Specifically in this e...

Embodiment 2

[0037] see figure 2 , the present embodiment is basically the same in structure as the first embodiment, the difference lies in the thickness setting of each layer, the sandwich layer, the first foam material layer 21, the second foam material layer 22, the third foam material layer 41 , the raw material of the fourth foam material layer 42, and the ratio of the release force of the two sides of the double-sided release paper are different. In this embodiment, the thickness of the substrate layer 3 is 25um, the thickness of the first anti-vibration layer 2 and the second anti-vibration layer 4 are both 17.5um, and the thickness of the first adhesive layer 1 and the second adhesive layer 5 is Both are 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...

Embodiment 3

[0044] see image 3 , the present embodiment is basically the same in structure as the first and second embodiments, the difference is that the thickness of each layer is set, the sandwich layer, the first foam material layer 21, the second foam material layer 22, the third foam material layer The raw materials of the layer 41, the fourth foam material layer 42, and the release force ratio of the two sides of the double-sided release paper are different.

[0045] Specifically, the thickness of the substrate layer 3 is 50um, the thickness of the first anti-vibration layer 2 and the second anti-vibration layer 4 are both 25um, and the thickness of the first adhesive layer 1 and the second adhesive layer 5 are both 50um , The thickness of the double-sided release paper 5 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 10um between the first foam mate...

Abstract

The invention discloses an enhanced rupture-proof shockproof adhesive tape. The adhesive tape comprises a base material layer, a first shockproof layer, a second shockproof layer, a first adhesive layer and a second adhesive layer, wherein the base material layer, with a dual-layer compound structure, comprises a foam layer and a PET film layer; the first shockproof layer and the second shockprooflayer are respectively adhered to two sides of the base material layer; and the first adhesive layer and the second adhesive layer are respectively adhered to the other sides of the first shockprooflayer and the second shockproof layer. The adhesive tape adopting the compound base material layer has certain flexibility, excellent fit performance and certain rupture-proof strength; and the designof the dual-layer shockproof layer can provide great elastic cushion to cargo loading and other situations, has good flatness since the dual-layer shockproof layer cannot be wrinkled due to thermal expansion, and can adapt to large range of temperature difference from negative 20 to 80 DEG C, so that the cargo transportation safety can be greatly improved. The adhesive tape has anticollision andshockproofing functions.

Description

technical field [0001] The invention belongs to the technical field of adhesive tapes, in particular to an enhanced 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, a...
