Description

Technical Field

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

[0002] Adhesive tape is composed of two parts: a base material and an adhesive. It connects two or more unconnected objects together through bonding. A layer of adhesive is coated on its surface. The earliest adhesives came from animals and plants. In the 19th century, rubber was the main component of adhesives. Various polymers are widely used in modern times. Adhesives can stick to things because bonds are formed between their own molecules and the molecules of the objects to be connected. This bond can firmly bond the molecules together. The composition of adhesives varies according to different brands and types, and there are various polymers.

[0003] Since the tape has a certain thickness, when the tape is adhered to a curved folding surface, due to the influence of its thickness, when it is bent, the inner curved surface is squeezed and wrinkles will appear, making it easy for water to enter the adhesive surface at the wrinkles, thereby causing the adhesive tape to fail and affecting the normal use of the tape. For this reason, we propose a waterproof tape. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a waterproof tape to solve the technical problems mentioned in the above background.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a waterproof tape, comprising a winding shaft, the outer wall of which is wound with tape, and the winding shaft is composed of a smooth winding surface and a hard cylinder, a waterproof layer is provided at the inner top end of the tape to achieve waterproofing of the tape, and an adhesive layer is provided at the inner bottom end of the tape to achieve bonding between the tape and an object.

[0006] By adopting the above technical solution, the waterproof layer can be used to waterproof the tape on a daily basis, thereby extending the service life of the tape and ensuring the use effect, and the waterproof glue can seal and waterproof the folds of the tape, further improving the waterproofness of the tape and significantly enhancing its service life.

[0007] The utility model is further configured that a filling layer is arranged inside the adhesive tape between the waterproof layer and the bonding layer.

[0008] By adopting the above technical solution, the stable use of the adhesive tape can be guaranteed.

[0009] The utility model is further configured that both sides of the end surface of the waterproof layer are provided with indication parts for prompting, and the indication parts are distributed at intervals on the outer wall of the waterproof layer.

[0010] By adopting the above technical solution, the position of the waterproof glue can be indicated.

[0011] The utility model is further configured that grooves are provided on both sides of the filling layer inside the adhesive tape, and the grooves are filled with waterproof glue.

[0012] By adopting the above technical solution, the folds of the tape are sealed and waterproofed.

[0013] The utility model is further configured that a sealing film for sealing the groove is provided at the end of the groove.

[0014] By adopting the above technical solution, a sealing effect is achieved on the groove.

[0015] In summary, the utility model mainly has the following beneficial effects:

[0016] 1. The utility model sets a waterproof layer. First, the two groups of materials to be bonded are placed together, and then the area to be bonded is dusted and dried to ensure the normal bonding of the tape. Then, one end of the tape can be bonded to the connection, and the elongation of the tape can be gradually increased by rotating the winding drum until the bonding area is completely bonded. The tape can be cut off. After the bonding of the tape is completed, the waterproof layer on the top can provide daily waterproofing for the tape, thereby ensuring the use effect of the tape and extending its service life;

[0017] 2. The utility model provides an indicator, a groove and a sealing film. After the tape is bonded, the bonding position of the tape is checked. When wrinkles are found, the waterproof glue in the groove can be squeezed to the wrinkles according to the indicator. Then the tape is pressed hard. At this time, the waterproof glue in the groove will break the sealing film and flow out of the groove to the wrinkles, which can not only fill the wrinkles but also have a waterproof effect. Therefore, the wrinkles of the tape are waterproofed while the wrinkles of the tape have a certain bonding ability, which improves the bonding quality of the tape. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0024] The following describes an embodiment of the utility model based on its overall structure.

[0025] A waterproof tape, such as Figure 1-4 As shown, it includes a reel 1, an outer wall of the reel 1 is wound with an adhesive tape 2, and the reel 1 is composed of a smooth reel surface and a hard tube, a waterproof layer 4 is provided at the top of the inner part of the adhesive tape 2 to achieve waterproofing of the adhesive tape 2, and an adhesive layer 5 is provided at the bottom of the inner part of the adhesive tape 2 to achieve adhesion between the adhesive tape 2 and the object;

[0026] Furthermore, in this embodiment, a filling layer 6 is provided inside the tape 2 between the waterproof layer 4 and the bonding layer 5 .

[0027] See also Figure 1 Both sides of the end surface of the waterproof layer 4 are provided with indication parts 3 for prompting, and the indication parts 3 are distributed at intervals on the outer wall of the waterproof layer 4 to indicate the position of the waterproof glue.

[0028] See also Figure 3-4 Grooves 7 are provided on both sides of the filling layer 6 inside the tape 2, and the grooves 7 are filled with waterproof glue. A sealing film 8 for sealing the grooves 7 is provided at the ends of the grooves 7 to achieve sealing and waterproofing of the folds of the tape 2.

[0029] The working principle of the utility model is as follows: first, two groups of materials to be bonded are placed together, and then the area to be bonded is dusted and dried to ensure the normal bonding of the tape 2, and then one end of the tape 2 can be bonded to the connection, and the elongation of the tape 2 can be gradually increased by rotating the winding drum 1 until the bonding area is completely bonded and the tape 2 can be cut off. After the bonding of the tape 2 is completed, the waterproof layer 4 on the top can waterproof the tape 2 on a daily basis, thereby ensuring the use effect of the tape 2 and extending its service life;

[0030] Furthermore, after the bonding of the tape 2 is completed, the bonding position of the tape 2 is checked. When wrinkles are found, the waterproof glue in the groove 7 can be squeezed to the wrinkles according to the indication part, and then the tape 2 is pressed hard. At this time, the waterproof glue in the groove 7 will break the sealing film 8 and flow out of the groove 7 to the wrinkles, which can not only fill the wrinkles but also have a waterproof effect. Therefore, the wrinkles of the tape 2 are waterproofed while the wrinkles of the tape 2 have a certain bonding ability, which improves the bonding quality of the tape 2.
