Description

A kind of PET double-sided adhesive

Technical field

The utility model relates to Cellphone Accessories technical field, specially a kind of PET double-sided adhesive.

Background technique

It in the process of manufacture of mobile phone, needs to fix adhesion electrical accessorie by double-sided adhesive, and generally makes at present When PET double-sided adhesive, can guarantee fixed stability, but existing PET double-sided adhesive also deposits some shortcomings when in use Place, such as double-sided adhesive are generally all protected glue-line back through protective layer, are avoided pollution or dry and cracked in storage, and existing Protective layer be mostly simple smooth finished board structure, two sides do not limit, and are not only easy dislocation and can not protect, but also are also easy to It causes glue-line to emerge because of squeezing, influences stickiness, while existing double-sided adhesive PET base layer is also single PET film, tie Structure intensity is low, is easily broken off, and using the inconvenient severing again of continuous reinforcing rib, greatly reduces the convenience used and steady It is qualitative.

Utility model content

The purpose of this utility model is to provide a kind of PET double-sided adhesives, to solve the problems mentioned in the above background technology.

To achieve the above object, the utility model provides the following technical solutions: a kind of PET double-sided adhesive, including PET base Layer, the both side surface of the PET base layer are equipped with protrusion, and the outer surface of the protrusion is coated with acrylic acid glue-line, the PET The fixed adhesion of the both side surface of basal layer has protective layer, and the both side surface of the protective layer is equipped with evacuation groove, described to keep away The inner surface of groove is allowed to be slidably connected to the outer surface of protrusion, the inner upper end of the PET base layer and lower end are fixed respectively It is inlaid with reinforcing fibre item and lower reinforcing fibre item, the upper surface of the PET base layer is equipped with upper angling hole, the PET base The lower surface of bottom is equipped with lower angling hole.

Preferably, the upper reinforcing fibre item and lower reinforcing fibre item are equidistantly staggeredly embedded in the interior of PET base layer Portion surface.

Preferably, the upper angling hole and lower angling hole equidistantly distributed, and be located at upper reinforcing fibre item respectively and it is lower plus Between strong fiber interspace.

Preferably, the PET base layer with a thickness of 0.05 millimeter to 0.1 millimeter.

Compared with prior art, the utility model has the beneficial effects that the PET double-sided adhesive coats third by two sides protrusion Olefin(e) acid glue-line is protected in conjunction with the protective layer with evacuation groove, and stability can be improved and avoid glue-line impaired or pollution, Simultaneously by the reinforcing fibre item of internal broken mosaic, in conjunction with the inclination pore structure being dislocatedly distributed, it is ensured that structural stability While, it is cut convenient for tearing manually, the convenience used and stability can be greatly improved in this way, guarantee bonding positioning Safety.

Fig. 3 is the partial schematic diagram that the upper angling hole of the utility model is arranged.

In figure: 1PET basal layer, 11 protrusions, 12 acrylic acid glue-lines, 13 protective layers, 14 evacuation grooves, reinforcing fibre on 15 Item, 16 lower reinforcing fibre items, angling hole, 18 lower angling holes on 17.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of PET double-sided adhesive, including PET base layer 1, PET base layer 1 with a thickness of 0.05 millimeter to 0.1 millimeter, on the one hand can guarantee structural strength, avoid excessively weak and break It splits, on the other hand convenient for being wound into, the both side surface of PET base layer 1 is equipped with protrusion 11, and the outer surface of protrusion 11 is coated with Acrylic acid glue-line 12 can be pasted with two sides, and convenient for side is connected Cellphone Accessories, and the other side can be fixed and adhere on shell It is fixed, facilitate stabilization, the fixed adhesion of the both side surface of PET base layer 1 has protective layer 13, and the both side surface of protective layer 13 is all provided with Have evacuation groove 14, the upper end of acrylic acid glue-line 12 can be protected, be avoided pollution in this way, but can from both sides sealing, It avoids squeezing out, guarantees the stability of stickiness, the inner surface of evacuation groove 14 is slidably connected to the outer surface of protrusion 11, PET base Fixation is inlaid with reinforcing fibre item 15 and lower reinforcing fibre item 16, upper reinforcing fibre respectively for the inner upper end of bottom 1 and lower end Item 15 and the equidistant interior surface for being staggeredly embedded in PET base layer 1 of lower reinforcing fibre item 16, can be dislocatedly distributed in this way, It can either guarantee the structural strength of support, while can be torn among gap, more convenient cutting improves the convenience used Property, equipped with upper angling hole 17, the lower surface of PET base layer 1 is equipped with lower angling hole 18, upper angling hole for the upper surface of PET base layer 1 17 and lower 18 equidistantly distributed of angling hole, and be located at respectively between upper reinforcing fibre item 15 and lower 16 gap of reinforcing fibre item, this Sample can avoid open upper reinforcing fibre item 15 and lower reinforcing fibre item 16, and then relatively labor-saving, convenience and high-efficiency when cutting.
