[0016] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only 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 person skilled in the art without creative labor belong to the range of protection of the utility model.
[0017] As Figs. 1-2As shown, the embodiment provides a double-layer easy-to-tear adhesive tape, which comprises a first substrate layer 1, a second substrate layer 2 and a non-stick film layer 3 arranged between the first substrate layer 1 and the second substrate layer 2, the width of the second substrate layer 2 is smaller than the width of the first substrate layer 1, the lower surfaces of the first substrate layer 1 and the second substrate layer 2 are adhered with adhesive layers (11, 12), the double-layer structure is formed by the mutual adhesion of the adhesive layer 12 on the lower surface of the second substrate layer 2, one side of the non-stick film layer 3 is adhered with the second substrate layer 2, and the other side extends to the direction of the first substrate layer 1 to form an easy-to-tear edge which is flush with the edge of the first substrate layer 1, the sum of the widths of the second substrate layer 2 and the non-stick film layer 3 after adhesion is equal to or slightly greater than the width of the first substrate layer 1, the width of the second substrate layer 2 is at least twice the width of the first substrate layer 1, and the width of the non-stick film layer 3 is at least half the width of the first substrate layer 1, in the embodiment, the first substrate layer 1 and the second substrate layer 2 are paper tapes, for example, using textured paper, which has good flexibility and is suitable for various surfaces, the non-stick film layer 3 uses plastic film, which is convenient to tear, the adhesive layers (11, 12) can be coated with acrylic adhesive, which has strong adhesion and low cost, the width of the second substrate layer 2 is two-thirds of the width of the first substrate layer 1 or slightly greater than two-thirds of the width of the first substrate layer 1, when the width of the second substrate layer 2 is two-thirds of the width of the first substrate layer 1, the edges of the first substrate layer 1 and the second substrate layer 2 are flush, when the width of the second substrate layer 2 is slightly greater than two-thirds of the width of the first substrate layer 1, the part of two-thirds of the width of the first substrate layer 1 extends along the edge of the first substrate layer 1, and the width of the non-stick film layer 3 is slightly greater than one-third of the width of the first substrate layer 1, the part of one-third of the width of the first substrate layer 1 is the part adhered with the second substrate layer 2, and the other edge of the non-stick film layer 3 and the second substrate layer 2 is flush.
[0018] In use, according to the size of the area to be shielded, the adhesive tape of appropriate length is cut. The adhesive layer on the lower surface of the first substrate layer of the adhesive tape is contacted and pressed with the substrate surface to be shielded, so that the adhesive tape is firmly adhered to the substrate, for example, in the process of painting the indoor wall, the skirting line needs to be shielded, the adhesive tape is pasted along the edge of the skirting line to ensure that the adhesive tape is closely attached to the wall surface without bubbles, wrinkles or gaps, thereby effectively preventing the paint from splashing on the skirting line during the spraying process, and the spraying operation is carried out, after completing the spraying operation once, the operator can easily tear the second substrate layer from the first substrate layer by grabbing the easy-to-tear edge formed by the non-stick film layer, so that the separation between the second substrate layer and the first substrate layer becomes extremely easy without the aid of other tools, and can be completed by hand, after tearing the second substrate layer, the first substrate layer still adheres to the substrate to continue to shield and protect the corresponding area, and the next spraying operation can be carried out at this time.
[0019] The first base material layer and the second base material layer are mutually adhered to form a double-layer structure, and the first base material layer and the second base material layer are separated by the non-adhesive layer; through the unique double-layer structure design, the non-adhesive film layer forms an easy-to-tear edge; after spraying, the second base material layer can be easily torn through the non-adhesive layer, and spraying can be continued; the problem that the traditional single-layer adhesive tape needs to be repeatedly adhered in multiple spraying is solved; the efficiency and convenience of the spraying operation are greatly improved; and the construction time and manpower investment are reduced.
