Abstract
The utility model relates to an improved structure of a double-sided foam adhesive tape. The improved structure comprises an adhesive tape substrate layer, wherein a surface adhesive is coated on each of two surfaces of the adhesive tape substrate layer, and a piece of isolating paper is arranged on each of the surface adhesive layers on two sides; a layer of primer coating is arranged between each of the two surfaces of the adhesive tape substrate layer and each surface adhesive layer; and a mixed layer formed by mixing the primer coating with the surface adhesive is arranged between each primer coating layer and each surface adhesive layer.
Description
Technical field
The utility model belongs to the insulation tape field, refers to that especially a kind of foam double sticky tape improves structure.
Background technology
The existing adhesive tape of Shi Yonging, generally the difference with matrix is divided into foam base adhesive tape, fabricbase adhesive tape, paper substrate adhesive tape or resin base adhesive tape.These all kinds of adhesive tapes are to make at face coating one deck glue of the material that is used as matrix respectively.Now the double sticky tape of Shi Yonging is to make at two-sided one deck glue that is coated with respectively of corresponding matrix.
On the other hand, existing adhesive tape is two-layer design, namely make adhesive tape at matrix coating one aspect glue, and face glue can't reach best combination with matrix, and it is loosening that the adhesive tape that therefore can often occur twining occurs, and has viscosity in the outside of the adjacent nexine of adhesive tape.
Particularly for double sticky tape, though double sticky tape has made things convenient for two objects are bonded together, because glue with the bonding force problem of matrix, is easy to cause adhesive tape sticking insecure and separate from the adhesive tape body portion.
The utility model content
The purpose of this utility model is to propose a technical scheme, and this technical scheme can solve double sticky tape bonding dynamics deficiency, easily from the problem of adhesive tape body portion separation, effectively raises the cohesive force of adhesive tape.
The utility model is achieved through the following technical solutions:
A kind of foam double sticky tape improves structure, includes the adhesive tape base layer, all is coated with the face glue-line on two surfaces of described adhesive tape base layer, and the face glue in both sides is respectively arranged with every paper; Between two surperficial coplanar glue of described adhesive tape base layer, also respectively be provided with one deck silane coupling agent; Between described silane coupling agent layer and face glue-line, be provided with the mixolimnion that is mixed by silane coupling agent and face glue.
Described double sticky tape thickness is between the 0.15-0.21mm.
The thickness of described glue is 3-5 times of silane coupling agent thickness.
The beneficial effect that the utility model is compared with prior art is:
It is calm good to have good glueability, weather resisteant energy and glue face.
Description of drawings
Fig. 1 is the expansion synoptic diagram of the utility model cross section.
Embodiment
Below by specific embodiment the technical solution of the utility model is described, following examples are just in order to illustrate the utility model rather than to limit scope of the present utility model.
As shown in Figure 1, a kind of foam double sticky tape includes adhesive tape foam base layer 11, all is coated with face glue-line (41,42) on two surfaces of described adhesive tape base layer, and the face glue-line in both sides is respectively arranged with every paper (51,52); Between two surperficial coplanar glue of described adhesive tape base layer 11, also respectively be provided with one deck silane coupling agent (21,22); Between described silane coupling agent layer and face glue-line, be provided with the mixolimnion (31,32) that is mixed by silane coupling agent and face glue.
Described double sticky tape thickness is between the 0.15-0.21mm.
The thickness of described glue is 3-5 times of silane coupling agent thickness.
Described adhesive tape base layer is prior art in this application, for example is that described foam base layer can be PE Foam base layer, moulding silica gel base layer, sponge base layer or eva base layer, to not clearly influence of the application.
Describedly in this application be generally two-sided separate-type paper every paper.
In the present embodiment, described glue is thermotropic pressure sensitive glue, for resin and rubber make by a certain percentage, in other embodiments, can select different face glue as required, the application is not produced detrimentally affect.
The production method of the technical program is as broad as long with prior art, therefore is not elaborated.
By the adhesive tape that present technique is produced, 180 degree stripping strengths are greater than 6.0N/25mm; Hold viscous force under the 1Kg/25mm situation greater than 30 minutes.
Above embodiment has illustrated the technical solution of the utility model, it will be appreciated by those skilled in the art that to be out of shape or to be equal to replacement by above-mentioned technical scheme, all can access other embodiment of the present utility model.
