[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0022] REFERENCE Figs. 1-3The utility model provides a kind of embodiment: a composite waterproof tape, including fixed shaft 1, the both sides of fixed shaft 1 are fixedly connected with limiting plate 2, such design can effectively prevent rotating roller 4 from producing transverse displacement in use process, to improve the stability of tape whole.

[0023] Fixed shaft 1 is rotatably connected with rotating roller 4 (reference Fig. 2 ), rotating roller 4 can rotate flexibly, so that it is more smooth when pulling tape, reduces the resistance of tape pulling. The outer bonding of rotating roller 4 has release film 5, release film 5 can well protect tape main body 6 when tape is not used, avoid dust and moisture contact tape adhesive surface, keep the adhesion and waterproof performance of tape.

[0024] The inner wall of release film 5 is bonded with tape main body 6, tape main body 6 is the main part of waterproof tape, has excellent adhesive property, can be firmly pasted on various substrates. The similar side of two limiting plates 2 is in contact with the outside of rotating roller 4, this design can prevent rotating roller 4 from separating from fixed shaft 1 due to external force, so that the stability of tape in use process is further improved.

[0025] The inside of tape main body 6 is provided with a reinforcing assembly for improving strength, which can increase the tear resistance of the tape when stretched, making it suitable for more severe use environment. The reinforcing assembly includes inner layer 7, which is polyurethane glue. This material has excellent waterproof performance, can effectively prevent external moisture penetration, and ensure the waterproof effect after pasting.

[0026] The inner wall of tape main body 6 is fixedly connected with inner layer 7, which enhances the overall strength of tape main body 6 and prevents delamination or peeling of inner layer 7 due to external force. One side of inner layer 7 is fixedly connected with middle layer 8, which is a PE film. This layer of PE film has good moisture resistance and certain flexibility, which can adapt to the bending of different surfaces and improve the applicability of the tape.

[0027] The end of middle layer 8 away from inner layer 7 is fixedly connected with reinforcing layer 9, which is a non-woven fabric. Non-woven fabric has high tensile resistance and wear resistance, which can improve the overall strength of the tape and prevent it from tearing during use, prolonging its service life. The end of reinforcing layer 9 away from middle layer 8 is fixedly connected with outer layer 10, which is an aluminum foil. Aluminum foil has good heat insulation and corrosion resistance, which can resist external light, moisture and chemicals, further improving the protection performance of the tape.

[0028] Working principle: when the adhesive tape is needed, the release film 5 is opened, at this time the release film 5 can drive the adhesive tape main body 6 to be opened, at this time the user can hold the handle 3, hold the adhesive tape, at this time the release film 5 can be normally pulled, the rotating roller 4 is rotated outside the fixed shaft 1, so that the use of the adhesive tape is facilitated, the convenience is improved;

[0029] The reinforcing assembly includes multiple layers of materials: the inner layer 7 is polyurethane glue, which has excellent waterproof performance, effectively isolates external moisture, and ensures the waterproof effect after pasting; the middle layer 8 uses PE film to provide moisture resistance and flexibility, so that the adhesive tape can adapt to different surface shapes; the reinforcing layer 9 is made of non-woven fabric, which has good tensile resistance and wear resistance, prolonging the service life of the adhesive tape; the outer layer 10 is aluminum foil, which has heat insulation and corrosion resistance functions, and can prevent the influence of light, moisture and chemicals on the adhesive tape. The overall structural design ensures the high strength, durability and protection performance of the adhesive tape, which is suitable for various environments.
