Abstract
The utility model discloses a directionally separated double-sided adhesive tape. The double-sided adhesive tape comprises a base material layer, a first adhesive layer, a second adhesive layer, a first release paper layer and a second release paper layer, wherein the first adhesive layer is arranged on one surface of the base material layer; the second adhesive layer is arranged on the other surface of the base material layer; the first release paper layer covers the first adhesive layer; the second release paper layer covers the second adhesive layer; the first adhesive layer is thicker than the second adhesive layer; or the first adhesive layer is a butyl acrylate pressure-sensitive adhesive layer, and the second adhesive layer is an ethyl acrylate pressure-sensitive adhesive layer. By using the structure that the first adhesive layer of the double-sided adhesive tape is thicker than the second adhesive layer or the first adhesive layer of the double-sided adhesive tape is the butyl acrylate pressure-sensitive adhesive layer and the second adhesive layer is an ethyl acrylate pressure-sensitive adhesive layer, when the viscosities of the two adhesive layers of the double-sided adhesive tape are inconsistent and the double-sided adhesive tape is detached, the double-sided adhesive tape is directionally separated and left on the surface of an article with high viscosity.
Description
Technical field
The utility model relates to a kind of adhesive tape of paste, relates in particular to a kind of double sticky tape of directional separation.
Background technology
In the daily life; adhesive tape is a kind of articles for use that people often use; existing adhesive tape custom only has single single face viscosity or all is to have biadhesive; also there be not in the market to find to have the biadhesive adhesive tape alternate with single face viscosity; and the size of the adhesive tape two sides viscosity of the double faced adhesive tape on the existing market all is consistent basically; when needs are separated coherent two objects of double faced adhesive tape adhesive tape again; adhesive tape can be pasted at random on two different objects; thereby two objects that the possibility random corrupted is stuck in removing; and in industrial production; some object is more valuable; need the valuable pasted object of special protection; when particularly relating between the dismounting chase of panel of LCD and the plastic rubber front frame adhesive tape; need to when removing double sticky tape, can allow the adhesive tape orientation stick on the plastic rubber front frame; and then protect valuable and easy impaired liquid crystal panel; this just needs a kind of stickiness of two adhesive layers of adhesive tape to differ greatly, and can realize the double sticky tape of directional separation during dismounting.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model provides that a kind of stickiness of two adhesive layers is inconsistent, can realize the double sticky tape of directional separation during dismounting.
For achieving the above object, the technical solution of the utility model is: a kind of double sticky tape of directional separation comprises substrate layer, the first adhesive layer, the second adhesive layer, the first off-style paper layer and the second off-style paper layer, described the first adhesive layer is arranged on substrate layer one surface, the second adhesive layer is arranged on another surface of substrate layer, the first off-style paper layer covers on the first adhesive layer, the second off-style paper layer covers on the second adhesive layer, and the thickness of described the first adhesive layer is greater than the thickness of the second adhesive layer.
A kind of double sticky tape of directional separation comprises substrate layer, the first adhesive layer, the second adhesive layer, the first off-style paper layer and the second off-style paper layer, described the first adhesive layer is arranged on substrate layer one surface, the second adhesive layer is arranged on another surface of substrate layer, the first off-style paper layer covers on the first adhesive layer, the second off-style paper layer covers on the second adhesive layer, described the first adhesive layer is the butyl acrylate pressure-sensitive adhesive layer, and the second adhesive layer is the ethyl propenoate pressure-sensitive adhesive layer.
Described the first off-style paper layer or the second off-style paper layer distribute for being interrupted, and discontinuities is provided with transition layer, the first off-style paper layer that described transition layer is corresponding with it or the second off-style paper layer consistency of thickness, and described discontinuities is for seamlessly transitting.
Described transition layer is the composite non-woven fabric layer.
Described the first off-style paper layer and the second off-style paper layer are provided with distinguishing identifier.
Adopt above structure, utilize the thickness of the first adhesive layer of double sticky tape greater than the thickness of the second adhesive layer, the first adhesive layer that perhaps adopts double sticky tape is the butyl acrylate pressure-sensitive adhesive layer, the second adhesive layer is the structure of ethyl propenoate pressure-sensitive adhesive layer, the stickiness of two adhesive layers of realization double sticky tape is inconsistent, during the dismounting double sticky tape, make its directional separation, double sticky tape can be stayed the large article surface of stickiness power, the off-style paper layer of double sticky tape of the present utility model distributes for being interrupted, discontinuities is for seamlessly transitting, discontinuities is provided with transition layer, and transition layer can be the composite non-woven fabric layer, has realized the function that single double sticky tape is alternate, and the composite non-woven fabric layer can reduce the transmission ofenergy between the connected piece, strengthens shock-absorbing function.
