Description

Technical Field

[0001] The utility model relates to the technical field of tapes, in particular to a special partition tape with anti-twist and easy tear-off properties. Background Art

[0002] CN210885906U discloses a special double-sided tape for building exterior wall partitioning, which is provided with a reinforcing layer on a black PET film, strengthening the bonding firmness of the black PET film and solving the problem that the current masking tape is prone to falling off during exterior wall partitioning. In actual construction, it is necessary to cut the tape with the aid of a cutting tool. And because the PET film is thin and light in weight, the tape is prone to twisting and bending due to factors such as misoperation and wind after being cut. The adhesive layers of the two parts before and after the twisted part of the tape face each other and are bonded together, making it difficult to separate, and only being able to be cut off, resulting in loss. Content of the Utility Model

[0003] Aiming at problems in the prior art solutions such as the tape being prone to twisting and needing to be cut with the aid of a cutting tool, the utility model provides a special partition tape with anti-twist and easy tear-off properties.

Reinforcing layers are provided on both sides of the base layer. An anti-twist net is further provided between the base layer and the adhesive layer. The anti-twist net includes longitudinally and transversely interwoven longitudinal fiber bundles and transverse fiber bundles. The extending direction of the longitudinal fiber bundles is perpendicular to the length direction of the tape, and a plurality of the longitudinal fiber bundles are arranged in sequence along the length direction of the tape. The extending direction of the transverse fiber bundles is parallel to the length direction of the tape, and a plurality of the transverse fiber bundles are arranged in sequence along the width direction of the tape. The arrangement density of the longitudinal fiber bundles in the length direction of the tape is greater than or equal to the arrangement density of the transverse fiber bundles in the width direction of the tape, and the linear density of the transverse fiber bundles is less than that of the longitudinal fiber bundles; The base layer is equidistantly provided with a plurality of dotted lines along the length direction, and the dotted lines are arranged between two adjacent longitudinal fiber bundles.

[0005] Preferably, the ratio of the linear density of the longitudinal fiber bundles to the linear density of the transverse fiber bundles is 2 - 5:1.

[0006] Preferably, the arrangement density of the longitudinal fiber bundles in the length direction of the tape is 10 - 50 roots / 10 cm, and the arrangement density of the transverse fiber bundles in the width direction of the tape is 6 - 30 roots / 10 cm.

[0007] Preferably, at least two continuously arranged longitudinal fiber bundles are taken as a group, and a dotted line is arranged between two adjacent groups.

[0008] Preferably, the extending direction of the dotted line is perpendicular to the length direction of the tape.

[0009] Preferably, the transverse fiber bundle extends in an S-shaped curve.

[0010] Preferably, the base layer is a black PET film.

[0016] The following further describes the embodiments of the present utility model in more detail with reference to the drawings and reference signs, so that those skilled in the art can implement it after studying this specification. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0017] The present utility model provides a special anti-twist and easy-to-tear grid tape as Figure 1-2 shown, which includes a base layer 10, a release paper adhered to one side of the base layer 10, and an adhesive layer 20 provided on the other side of the base layer 10. Reinforcement layers 11 are provided on both sides of the base layer 10. The base layer 10 can be a black PET film to replace the black primer; the adhesive layer 20 can be an adhesive such as self-adhesive to adhere the tape to the exterior wall; when spraying real stone paint, the real stone paint adheres the reinforcement layer 11 to the exterior wall, and the release paper protects the base layer from being contaminated by the real stone paint. The edge of the reinforcement layer 11 can be wavy, and through holes 12 are also provided at its wave crests to increase the contact area and bonding strength between the real stone paint and the reinforcement layer; after the real stone paint is sprayed, the release paper is torn off to expose the base layer, and the grid is completed.

[0018] In this embodiment, an anti-twist net 30 is further disposed between the base layer 10 and the adhesive layer 20 to increase the anti-twist performance of the tape and prevent the two parts of the adhesive layer 20 of the tape from sticking together after twisting, resulting in loss. Please refer to Figure 1 , the anti-twist net includes longitudinally and transversely interwoven longitudinal fiber bundles 31 and transverse fiber bundles 32. The extending direction of the longitudinal fiber bundles 31 is perpendicular to the length direction of the tape, and the extending direction of the transverse fiber bundles 32 is parallel to the length direction of the tape. The linear density of the transverse fiber bundles 32 is less than that of the longitudinal fiber bundles 31. The greater the linear density, the thicker the fiber. In this embodiment, the ratio of the linear density of the longitudinal fiber bundles 31 to the transverse fiber bundles 32 is 2-5:1.

[0019] Both the longitudinal fiber bundles 31 and the transverse fiber bundles 32 can be made of synthetic fibers such as glass fibers and polyester fibers. The longitudinal fiber bundles 31 are perpendicular to the length direction of the tape and have a thicker diameter. A plurality of longitudinal fiber bundles are arranged in sequence along the length direction of the tape to enhance the strength of the tape as a reinforcing rib and effectively prevent twisting and bending. The thinner transverse fiber bundles 32 extend along the length direction of the tape. A plurality of transverse fiber bundles are arranged in sequence along the width direction of the tape, and the arrangement density of the longitudinal fiber bundles in the length direction of the tape is greater than or equal to the arrangement density of the transverse fiber bundles in the width direction of the tape. The transverse fiber bundles are relatively sparse and mainly serve to connect the longitudinal fiber bundles 31 and make the tape easy to roll up, facilitating packaging and transportation. Preferably, the transverse fiber bundles 32 extend in an S-shaped curve to slightly increase the strength. Preferably, the warp and weft densities of the anti-twist net are both low to reduce costs while ensuring a certain anti-twist performance. Specifically, the arrangement density of the longitudinal fiber bundles 31 in the length direction of the tape is 10-50 pieces / 10 cm, and the arrangement density of the transverse fiber bundles in the width direction of the tape is 6-30 pieces / 10 cm.

[0020] A plurality of dotted broken lines 40 are equidistantly arranged along the length direction of the base layer 10, and their extending direction is perpendicular to the length direction of the tape. The dotted broken lines 40 are arranged between adjacent two longitudinal fiber bundles 31 to facilitate tearing the tape along the dotted broken lines 40, reducing the dependence on cutting tools during construction and improving efficiency. The thinner and sparser transverse fiber bundles 32 are also beneficial to the tearing of the tape. A plurality of non-connected and linearly arranged grooves can be pressed on the base layer 10 to form the dotted broken lines 40. In this embodiment, taking 2 continuously arranged longitudinal fiber bundles 31 as a group, one dotted broken line 40 is arranged between adjacent two groups. In other embodiments, one longitudinal fiber bundle can be taken as a group, or more longitudinal fiber bundles can be taken as a group. The higher the density of the dotted broken lines 40, the smaller the loss of the tape during construction. The dotted broken lines 40 will reduce the strength of the tape, but the strength requirement for the tape in the grid operation is low, and the anti-twist net also improves a certain strength.

[0021] The above are one or more embodiments of the present utility model, and the description thereof is relatively specific and detailed. However, it should not be construed as a limitation to the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several variations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
