[0022] The technical scheme in the embodiments of the utility model will be apparently and completely described in combination with the drawings in the embodiments of the utility model, and apparently, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without making the creative labor all belong to the range of protection of the utility model.
[0023] Please refer to Figures 1-5 The utility model provides a kind of technical scheme: a kind of anti-warping PET adhesive tape, including PET adhesive tape layer 6, still include,
[0024] The covering layer 1 is fixedly connected with the nanometer film 5 on one side of the PET tape layer 6, and the nanometer film 5 protects the outer side of the PET tape layer 6. The side of the nanometer film 5 away from the PET tape layer 6 is glued to one side of the covering layer 1. The four side edges of the nanometer film 5 and the four side edges of the covering layer 1 are all left with gaps for fingers to stretch in and tear;
[0025] The two ends of the covering layer 1 are fixedly connected with the connecting layer one 2 and the connecting layer two 3, respectively. The connecting layer one 2 and the connecting layer two 3 are both L-shaped and are mutually glued and occluded. The connecting layer two 3 is provided with a groove 4 on the side away from the covering layer 1, for fingers to stretch in and tear the connecting layer two 3 and the connecting layer one 2 apart;
[0026] The surface of the connecting layer two 3 at the opening of the groove 4 is provided with an arc shape, leaving a gap for fingers to stretch in the groove 4 and facilitate operation;
[0027] The PET tape layer 6 is fixedly connected with the shielding layer 7 on the side away from the nanometer film 5. The shielding layer 7 is made of copper foil, which is conducive to shielding electromagnetic waves;
[0028] The shielding layer 7 is fixedly connected with the adhesive layer 8 on the side away from the PET tape layer 6, for being adhered to an object;
[0029] The covering layer 1 is provided with a dotted line groove 9 in the middle, for tearing the covering layer 1 apart from the middle and taking it off the nanometer film 5;
[0030] The opening edge of the dotted line groove 9 is provided with an arc surface, for fingers to stretch in the opening of the dotted line groove 9 and hold the edge on the other side to tear.
[0031] Working principle: The covering layers 1 are glued and adhered together by the connecting layer one 2 and the connecting layer two 3 to form a whole, and are rolled together for convenient storage and keeping the adhesive layer 8 from being contaminated. The nanometer film 5, the PET tape layer 6, the shielding layer 7 and the adhesive layer 8 are adhered together and have the same shape and size. The size of the covering layer 1 is slightly larger than that of the nanometer film 5, so that the edge of the covering layer 1 extends from the edge of the nanometer film 5 by a distance, facilitating fingers to stretch in the gap and tear. The edges of the nanometer film 5 are not torn apart. The nanometer film 5, the PET tape layer 6, the shielding layer 7 and the adhesive layer 8 are in a separated state. The body is not affected when the connecting layer one 2 and the connecting layer two 3 are torn, so as to avoid warping;
[0032] When bonding to the object, the single covering layer 1 in roll shape is pulled into a flat shape by holding the connecting layer one 2, then the fingers of the other hand are inserted into the recess 4 on the other side of the covering layer 1, then the connecting layer two 3 is torn apart from the adjacent connecting layer one 2, the connecting layer one 2 and the connecting layer two 3 are staggered with the PET tape layer 6, so that the tearing process does not affect the flatness of the PET tape layer 6, and the connecting layer one 2 and the connecting layer two 3 are set as L-shaped and mostly overlap, reduce the length of occupation in the state of keeping bonding, avoid excessive material waste, then press the bonding layer 8 on the position needing bonding for a period of time, after the bonding is firm, the fingertips are inserted into the side of the arc surface opening in the dashed line slot 9, the covering layer 1 is slowly torn from the middle and separated from the nanometer film 5, since the covering layer 1 edge and the nanometer film 5 edge have a gap, therefore the covering layer 1 does not affect the nanometer film 5 edge when separating from the nanometer film 5 surface, and the separation from the middle is more stable than the four corners, reduces the warping probability.
