Description
Technical Field
The utility model relates to a can move gluey technical field, specifically be a polyurethane can move gluey.
Background
The thermoplastic polyurethane has the characteristics of high tension, good toughness and aging resistance, is a mature environment-friendly material, but has the characteristics of low surface energy and difficult bonding with an adhesive, so that the application of the environment-friendly material as an adhesive tape base material is hindered.
When the existing polyurethane removable adhesive is used for sticking articles such as mobile phone supports, bathroom hooks and the like, the sticking stability is poor, and the polyurethane removable adhesive cannot be reused. Therefore, it is necessary to design a removable polyurethane adhesive.
SUMMERY OF THE UTILITY MODEL
To the above situation, for overcoming prior art's defect, the utility model provides a polyurethane can move gluey, this polyurethane can move gluey novel structure, think about ingeniously, not only have good waterproof performance, and the bonding is firm, but reuse can be used to the pasting of cell phone stand, articles such as bathroom couple.
In order to achieve the above object, the utility model provides a following technical scheme: a polyurethane removable adhesive comprises an adhesive layer, a first release film layer and a second release film layer, wherein the top and the bottom of the adhesive layer are respectively covered with the first release film layer and the second release film layer;
the viscose layer includes first glue layer, PU elastomer layer, PET rete and second glue layer, the bottom on PET rete covers there is the second glue layer, the top on PET rete covers there is PU elastomer layer, the top on PU elastomer layer covers there is first glue layer.
Preferably, the first glue layer is a polyurethane glue layer, and the second glue layer is an acrylic glue layer.
Preferably, the thickness of the first release film layer and the second release film layer is 50 um.
Preferably, the thickness of the PU elastomer layer is 300-800 um.
Preferably, the thickness of the PET film layer is 50-100 um.
Preferably, the thickness of the first glue layer and the second glue layer is 50-180 um.
The utility model has the advantages that:
use PU elastomer layer and PET rete as the base member layer of viscose layer, not only have good waterproof nature, also have certain stretchability and elasticity moreover, first glue layer adopts the polyurethane viscose to make, not only has the characteristics that viscidity is high and can wash, the reuse of being convenient for moreover, second glue layer adopts the ya keli glue film to make, viscidity is high, bonds firmly, the effectual fixed stability of having guaranteed.
