Description

Technical Field

[0001] The utility model relates to the technical field of adhesive tapes, in particular to a highly light-transmitting adhesive tape. Background Art

[0002] Tape is a sticky strip material, usually used for various purposes such as bonding, encapsulation, packaging, and fixation. Tape is usually composed of glue and plastic film. Common types include transparent tape, colored tape, double-sided tape, etc.

[0003] The above-mentioned and existing technologies have the following defects: when producing the tape, the tape is wound on a paper tube, so the glue on the outer ring of the tape will stick to the plastic film on the inner ring of the tape. When the tape is unfolded for use, glue residue is likely to remain on the surface of the plastic film, causing the light transmittance of the plastic film of the tape to decrease, thereby affecting the use effect of the tape.

[0004] Therefore, a highly light-transmitting adhesive tape is proposed. Utility Model Content

[0005] The utility model aims to solve the shortcoming that glue residue is easily left on the surface of the plastic film, which causes the light transmittance of the plastic film of the tape to decrease, and proposes a highly light-transmitting tape.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a highly light-transmitting adhesive tape, comprising a transparent tape and a paper tube, wherein the transparent tape is wound around the arc surface of the paper tube, an adhesive layer is glued to the surface of the transparent tape, and a release film is glued to the side of the adhesive layer away from the transparent tape.

[0007] The effect achieved by the above components is: by sticking a layer of release film on the surface of the adhesive layer, when the transparent tape is wrapped around the arc surface of the paper tube, it can prevent the adhesive layer on the outside from contacting the transparent tape on the inside, thereby preventing the adhesive layer from remaining on the surface of the transparent tape, thereby improving the light transmittance of the transparent tape.

[0008] Preferably, a reinforcing net is fixedly connected to the release film, and the reinforcing net is an aramid fiber woven net.

[0009] The effect achieved by the above components is: since aramid fibers have high strength, the reinforcing mesh woven from aramid fibers can increase the strength of the release film, thereby enabling the release film to better protect the transparent tape.

[0010] Preferably, an anti-pollution film is fixedly connected to a side of the transparent belt away from the adhesive layer, and the anti-pollution film is a polytetrafluoroethylene film.

[0011] The effect achieved by the above components is: since the surface tension of the polytetrafluoroethylene film is small, it is difficult for pollutants to adhere to the surface of the polytetrafluoroethylene film. The anti-pollution film can facilitate the removal of pollutants attached to the surface of the transparent belt and reduce the adhesion of pollutants, thereby improving the light transmittance of the transparent belt.

[0012] Preferably, a flexible film is fixedly connected to a side of the release film away from the adhesive layer.

[0013] The effect achieved by the above components is that after the transparent tape is wound, the flexible film located on the inner side can prevent the release film from damaging the anti-pollution film.

[0014] Preferably, a connecting strip is fixedly connected to a side of the flexible film close to the release film, and the connecting strip is fixedly connected to the release film.

[0015] The effect achieved by the above components is that the connecting strip can improve the connection strength between the flexible film and the release film.

[0016] Preferably, a plurality of scale grooves are provided on a side of the flexible film away from the release film.

[0017] The effect achieved by the above components is that the scale groove can easily grasp the unfolded length of the transparent tape, thereby facilitating the tearing of the tape of appropriate size and reducing the waste of tape.

[0018] Compared with the prior art, the advantages and positive effects of the present invention are:

[0019] In the present invention, by attaching a release film to the surface of the adhesive layer, when the transparent tape is wound around the arc surface of the paper tube, the adhesive layer on the outside is prevented from contacting the transparent tape on the inside, thereby preventing the adhesive layer from remaining on the surface of the transparent tape, thereby improving the light transmittance of the transparent tape.

[0024] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] like Figure 1-Figure 3 As shown, the utility model provides a high-light-transmittance adhesive tape, including a transparent tape 1 and a paper tube 2, the transparent tape 1 is wound on the arc surface of the paper tube 2, the surface of the transparent tape 1 is glued with an adhesive layer 3, and the side of the adhesive layer 3 away from the transparent tape 1 is glued with a release film 4, by sticking a layer of release film 4 on the surface of the adhesive layer 3, when the transparent tape 1 is wound on the arc surface of the paper tube 2, the adhesive layer 3 on the outside can be prevented from contacting the transparent tape 1 on the inside, thereby preventing the adhesive layer 3 from remaining on the surface of the transparent tape 1, thereby improving the light transmittance of the transparent tape 1, a reinforcing net 5 is fixedly connected to the release film 4, and the reinforcing net 5 is an aramid fiber woven net. Since the strength of aramid fiber is relatively high, the reinforcing net 5 woven from aramid fiber can improve the strength of the release film 4, so that the release film 4 can better protect the transparent tape 1.

[0027] like Figure 1-Figure 3 As shown, the side of the transparent tape 1 away from the adhesive layer 3 is fixedly connected to an anti-pollution film 6, and the anti-pollution film 6 is a polytetrafluoroethylene film. Since the surface tension of the polytetrafluoroethylene film is small, it is difficult for pollutants to adhere to the surface of the polytetrafluoroethylene film. The anti-pollution film 6 can facilitate the removal of pollutants attached to the surface of the transparent tape 1 and reduce the adhesion of pollutants, thereby improving the light transmittance of the transparent tape 1. The side of the release film 4 away from the adhesive layer 3 is fixedly connected to a flexible film 7. After the transparent tape 1 is wound, the flexible film 7 located on the inner side can prevent the release film 4 from damaging the anti-pollution film 6. The side of the flexible film 7 close to the release film 4 is fixedly connected to a connecting strip 8. The connecting strip 8 is fixedly connected to the release film 4. The connecting strip 8 can improve the connection strength between the flexible film 7 and the release film 4. The side of the flexible film 7 away from the release film 4 is provided with a plurality of scale grooves 9. The scale grooves 9 can facilitate the grasp of the unfolded length of the transparent tape 1, thereby facilitating the tearing of the tape of appropriate size and reducing the waste of tape.

[0028] The overall working principle is that by attaching a layer of release film 4 to the surface of the adhesive layer 3, when the transparent tape 1 is wound on the arc surface of the paper tube 2, the adhesive layer 3 on the outside is prevented from contacting the transparent tape 1 on the inside, thereby preventing the adhesive layer 3 from remaining on the surface of the transparent tape 1, thereby improving the light transmittance of the transparent tape 1. Since the strength of aramid fiber is relatively high, the reinforcing mesh 5 woven from aramid fiber can improve the strength of the release film 4, so that the release film 4 can better protect the transparent tape 1. Since the surface tension of the polytetrafluoroethylene film is relatively low, it is difficult for pollutants to adhere to the polytetrafluoroethylene film. The surface of the olefin film, the anti-pollution film 6 can facilitate the removal of pollutants attached to the surface of the transparent tape 1 and reduce the adhesion of pollutants, thereby improving the light transmittance of the transparent tape 1. After the transparent tape 1 is wound, the flexible film 7 located on the inner side can prevent the release film 4 from damaging the anti-pollution film 6. The connecting strip 8 can improve the connection strength between the flexible film 7 and the release film 4. The scale groove 9 can facilitate the unfolding length of the transparent tape 1, thereby facilitating the tearing of the tape of appropriate size and reducing the waste of the tape. When using the tape, the release film 4 is peeled off and the transparent tape 1 can be pasted on the surface of the product with the help of the adhesive layer 3.
