Description

Technical Field

[0001] The utility model belongs to the technical field of tape equipment, and specifically relates to a waterproof and moisture-proof tape. Background Art

[0002] According to the patent document with the authorization announcement number "CN216513642U" and the invention name "A waterproof tape", it is recorded in the specification: When the tape is needed, first tear off the fitting isolation layer, and then stick it to the designated position through the adhesive layer. When encountering a water environment, the second waterproof layer can be used for waterproofing, thereby protecting the adhesive layer and preventing the adhesive force of the adhesive layer from decreasing. And water can be absorbed through the water absorption layer and then stored through the silica gel layer, so as to achieve the waterproof effect. Moreover, the elasticity of the tape can be increased through the stress relaxation layer and the elastic rubber layer. When the tape is no longer needed, the protective film layer can be torn off through the tear strip in the groove, but there are still the following defects:

[0003] When the tape adheres to an object, an adhesive layer is formed between the tape and the object. When there is rain, water directly contacts the adhesive layer through the gap between the tape and the object, affecting the adhesiveness of the adhesive layer. Content of the Utility Model

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a waterproof and moisture-proof tape, which effectively solves the problem that water may contact the adhesive layer through the gap between the tape and the object, affecting the adhesiveness of the adhesive layer.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A waterproof and moisture-proof tape, including a tape outer layer, a tape inner layer is provided below the tape outer layer, and an adhesive layer is provided between the tape outer layer and the tape inner layer;

[0006] Among them, the tape outer layer plays an external waterproof role for the adhesive layer, and the tape inner layer plays an inner waterproof role for the adhesive layer.

[0007] Preferably, the tape outer layer includes a first base layer, the adhesive layer is coated on the bottom of the first base layer, a first waterproof layer is provided above the first base layer, and a second waterproof layer is provided above the first waterproof layer. Both the first waterproof layer and the second waterproof layer play an external waterproof role for the adhesive layer.

[0008] Preferably, a rubber protection layer is provided between the first waterproof layer and the second waterproof layer, and the rubber protection layer is used to buffer and protect the tape.

[0009] Preferably, an external protection layer is provided on the side of the second waterproof layer away from the first base layer, and the external protection layer is used to externally protect the tape.

[0010] Preferably, the inner layer of the tape includes a fixed adhesion layer provided below the adhesive layer. Through grooves are equidistantly formed in the fixed adhesion layer, and a separable adhesion layer is provided inside the through grooves.

[0011] Preferably, the fixed adhesion layer includes a second base layer, and a third waterproof layer is provided at the bottom of the second base layer. The third waterproof layer is used to provide inner waterproofing for the adhesive layer.

[0012] Preferably, the separable adhesion layer includes a third base layer disposed inside the through grooves. Adhesive layers are symmetrically installed on both sides of the third base layer and are fixedly connected to the inner side walls of the through grooves. A connecting strip is coated at the bottom end of the third base layer. When the tape is wound, the third base layer adheres to the outer wall of the inner tape through the connecting strip. When the tape is pulled out, the third base layer separates from the inside of the through grooves.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] During operation, when the tape provided is adhered to an object, the third base layer detaches from the inside of the through grooves, and the adhesive layer between the outer layer and the inner layer of the tape adheres to the object through the through grooves to complete adhesion. At the same time, the third waterproof layer contacts the surface of the object to prevent water from contacting the adhesive layer, providing inner waterproofing. The first waterproof layer and the second waterproof layer on the outer layer of the tape provide outer waterproofing, improving the waterproof and moisture-proof effects.

[0015] During operation, the third base layer is provided inside the through grooves through the adhesive layers, and the third base layer adheres to the outer wall of the inner tape outer layer through the connecting strip. When the tape is pulled outwards, due to the third base layer adhering to the outer wall of the inner tape outer layer, under the action of the pulling force, the adhesive layers break, causing the third base layer to remain on the outer wall of the inner tape outer layer, opening the respective through grooves on the fixed adhesion layer at the bottom end of the pulled-out outer layer of the tape, enabling the adhesive layer to adhere to the object, facilitating use.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments; based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment 1, given by Figures 1-5 The present utility model relates to a waterproof and moisture-proof tape, including an outer layer 1 of the tape. A tape inner layer 3 is provided below the outer layer 1 of the tape. An adhesive layer 2 is provided between the outer layer 1 of the tape and the inner layer 3 of the tape. Among them, the outer layer 1 of the tape plays an external waterproof role for the adhesive layer 2, and the inner layer 3 of the tape plays an inner waterproof role for the adhesive layer 2.

[0026] The outer layer 1 of the tape includes a first base layer 101. The adhesive layer 2 is coated on the bottom of the first base layer 101. A first waterproof layer 102 is provided above the first base layer 101, and a second waterproof layer 103 is provided above the first waterproof layer 102. Both the first waterproof layer 102 and the second waterproof layer 103 play an external waterproofing role for the adhesive layer 2. A rubber protection layer 104 is provided between the first waterproof layer 102 and the second waterproof layer 103, and the rubber protection layer 104 is used to buffer and protect the tape. An external protection layer 105 is provided on the side of the second waterproof layer 103 away from the first base layer 101, and the external protection layer 105 is used to externally protect the tape. The inner layer 3 of the tape includes a fixed attachment layer 301 provided below the adhesive layer 2. Through grooves 302 are equidistantly formed in the fixed attachment layer 301. A separable attachment layer 303 is provided inside the through grooves 302. The fixed attachment layer 301 includes a second base layer 3011. A third waterproof layer 3012 is provided at the bottom of the second base layer 3011, and the third waterproof layer 3012 is used to provide inner waterproofing for the adhesive layer 2. The separable attachment layer 303 includes a third base layer 3031. The third base layer 3031 is arranged inside the through grooves 302. Adhesive layers 3032 are symmetrically installed on both sides of the third base layer 3031, and the adhesive layers 3032 are fixedly connected to the inner side walls of the through grooves 302. A connecting strip 3033 is coated at the bottom end of the third base layer 3031. When the tape is wound, the third base layer 3031 adheres to the outer wall of the inner tape outer layer 1 through the connecting strip 3033. When the tape is pulled out, the third base layer 3031 separates from the inside of the through grooves 302. When the tape adheres to an object, the third base layer 3031 detaches from the inside of the through grooves 302, and the adhesive layer 2 between the tape outer layer 1 and the tape inner layer 3 adheres to the object through the through grooves 302 to complete the adhesion. At the same time, the third waterproof layer 3012 contacts the surface of the object to prevent water from contacting the adhesive layer 2 and play an inner waterproofing role. The first waterproof layer 102 and the second waterproof layer 103 on the tape outer layer 1 play an outer waterproofing role to improve the waterproof and moisture-proof effect. The third base layer 3031 is arranged inside the through grooves 302 through the adhesive layers 3032, and the third base layer 3031 adheres to the outer wall of the inner tape outer layer 1 through the connecting strip 3033. When the tape is pulled outwards, due to the third base layer 3031 adhering to the outer wall of the inner tape outer layer 1, under the action of the pulling force, the adhesive layers 3032 break, causing the third base layer 3031 to remain on the outer wall of the inner tape outer layer 1, opening each through groove 302 on the fixed attachment layer 301 at the bottom end of the pulled-out tape outer layer 1, enabling the adhesive layer 2 to adhere to the object and facilitating use.

[0027] Working principle: During operation, first, when the tape is in a wound state, the third base layer 3031 is arranged inside the through grooves 302 through the adhesive layers 3032, and the third base layer 3031 adheres to the outer wall of the inner tape outer layer 1 through the connecting strip 3033;

[0028] When using the tape and pulling the tape outwards, since the third base layer 3031 adheres to the outer wall of the inner tape outer layer 1, under the action of the pulling force, the adhesive layer 3032 disconnects, causing the third base layer 3031 to remain on the outer wall of the inner tape outer layer 1, enabling each through groove 302 on the fixed attachment layer 301 at the bottom end of the tape outer layer 1 to be opened. When the tape adheres, the adhesive layer 2 adheres to the object through the through groove 302;

[0029] Since there is a fixed attachment layer 301 outside the position where the adhesive layer 2 adheres to the object, the third waterproof layer 3012 can prevent the gap between the tape outer layer 1 and the object from contacting the adhesive layer 2, ensuring the adhesion effect. At the same time, the first waterproof layer 102 and the second waterproof layer 103 are provided on the tape outer layer 1, which can play a waterproof role on the outside of the tape outer layer 1, thereby improving the waterproof and moisture-proof effect of the tape.
