Abstract
The utility model discloses an ultra -thin double -sided tape, including PET sheet layer (1), ya keli glue film (2), from type layer (3), ya keli glue film (2) thickness be 5 mu m-20 mu m, the coating is in the both sides on PET sheet layer (1), cover in ya keli glue film (2) the outside (b) from type layer (3), (B, ) the utility model provides an inferior gram force adhesive thickness is 5 mu m-20 mu m, and viscidity can reach 2000-3000g25mm, current ultra -thin double -sided tape on the market, and under equal sticky prerequisite, adhesive thickness has reduced by 10 mu m, can satisfy most ultra -thin electronic demand on the market.
Description
Technical field
The utility model relates to adhesive tape, particularly relates to a kind of ultrathin double-face adhesive tape.
Background technology
At present, domestic application is in the double sticky tape of electronics industry, and in order to meet close-burning performance requriements, general one side bondline thickness is at 30-30 μm, and thickness is relatively thick, can not meet ultra-thin requirement to some ultrathin electronic product.Chinese patent publication No. is that the patent of invention of CN102965044A discloses " a kind of ultrathin double-face adhesive tape ", this adhesive tape is primarily of PET release film, vinylformic acid glue, PET transparent film composition, integral thickness is about 0.1mm, has processibility and the excellent beneficial effect of workability.But this adhesive tape is in order to reach ultrathin design requirement, and vinylformic acid glue thickness is designed to 4 μm, adhesive tape viscosity is not enough, is of limited application.
Utility model content
The purpose of this utility model overcomes above-mentioned defect, while reduction tape thickness, meet the adhesive requirement of glue, not only be applicable to ultrathin electronic product field, also can be widely used in leather, the field such as inscription plate, stationery, automobile edging are fixed, footwear industry, paper processed, handicraft stickup location.
The utility model realizes by the following technical solutions: ultrathin double-face adhesive tape, comprise PET sheet layer (1), acrylic glue-line (2), release layer (3), described acrylic glue-line (2) thickness is 5 μm ~ 20 μm, be coated in the both sides of PET sheet layer (1), described release layer (3) covers acrylic glue-line (2) outside.
Further, the one that described acrylic glue-line (2) is acrylate glue water layer or pressure sensitive adhesive water layer.
Further, acrylic glue-line (2) thickness being coated in the both sides of PET sheet layer (1) is identical.
Further, described PET sheet layer (1) thickness is 23 μm ~ 150 μm, and the thickness of described release layer (3) is 23 μm ~ 150 μm.
Owing to have employed said structure, acrylic bondline thickness in the utility model is 5 μm ~ 20 μm, PET sheet layer two rear flank is coated in through coextru-lamination technique, tape thickness is even, viscosity can reach 2000 ~ 3000g/25mm, and more existing ultrathin double-face adhesive tape on the market, under the prerequisite of equal viscosity, bondline thickness reduces 10 μm, can meet the demand of most of super-thin electronic on the market.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with the drawings and the specific embodiments, the utility model is described further.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, ultrathin double-face adhesive tape, comprises PET sheet layer 1, acrylic glue-line 2, release layer 3, and described acrylic glue-line 2 thickness is 5 μm ~ 20 μm, is coated in the both sides of PET sheet layer 1, and described release layer 3 covers outside acrylic glue-line 2.
Embodiment 1:
