[0002] Butyl tape can be widely used in the fields of construction, automobile, shipbuilding, electronics, etc. for sealing and bonding, such as waterproof sealing of roofs, walls, carriages, hulls, etc., as well as bonding of metals, plastics, glass and other materials. In short, butyl tape is a high-performance, environmentally friendly sealing and bonding material with broad application prospects and market demand.

[0003] At present, most of the processes of applying butyl tape to automobile bodies are done by manual pressing. During the pressing process, there will be uneven force on the adhesive surface, and the part of the tape that is partially adhered will bulge or part of the tape will fall off due to temperature changes.

[0004] Therefore, the present application adopts a tape structure that can be protected by a double-sided auxiliary layer, which can effectively remove impurities and dust on the outside of the colloid, and at the same time cooperate with the hand to press the roller structure to evenly press the glue application process. This can improve the adhesion between the glue surface and the attachment surface, and it is not easy to bulge or fall off. At the same time, the adhesive layer structure at the tail of the colloid can facilitate the subsequent glue force without touching the colloid itself, ensuring that the glue body achieves the effect of dust-free glue.

[0014] The beneficial effects of the utility model are:

[0015] Compared with the prior art, the present application adopts a tape structure that can be protected by a double-sided auxiliary layer, which can effectively remove impurities and dust on the outside of the colloid, and at the same time cooperate with the hand-pressing roller structure to evenly press the glue-sticking process. This can improve the adhesion between the glue surface and the attachment surface, and it is not easy to bulge or fall off.

DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific implementations. It should be understood that the following specific implementations are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0021] like Figure 1 and Figure 2 As shown, a butyl sealing tape for automobiles includes a colloid; the upper and lower end surfaces of the colloid 2 are pasted with an upper covering layer 1 and a lower covering layer 3; wherein the upper and lower end surfaces of the colloid 2 are installed with two sets of covering layers, and the covering layers are used to protect the colloid 2 from dust and impurities when it is not in use. Moreover, the shape of the colloid 2 can be changed at any time when it is in use.

[0022] The upper covering layer 1 is a double-layer structure, and is composed of a main covering film 6 and a secondary covering film 7. The main covering film 6 has a main adhesive layer 5 extending behind the colloid 2, and the main adhesive layer 5 is folded to be in a close contact state; wherein, the main covering film 6 and the secondary covering film 7 are used as tearing film structures for subsequent operations, which are convenient for manual operation and complete the colloid covering without touching the colloid 2 itself. When in a state to be used, the upper covering layer 1 is in a folded state to avoid exposure and damage.

[0023] The main adhesive layer 5 is extended with a secondary adhesive layer 8 along the rear of the colloid 2, and the secondary adhesive layer 8 is folded and in a close contact state; wherein, similarly, the secondary adhesive layer 8 is the lower layer in the double-layer structure, and cooperates to complete the uniform rolling of the rubber surface without affecting the protective layer of the surface structure of the colloid 2. When in the state of being used, it is in a folded state to avoid being exposed and damaged.

[0024] A peeling film 12 is provided on the back of the lower cover layer 3 along the back of the colloid 2, and the peeling film 12 is integrally connected with the lower cover layer 3. The peeling film 12 is an anti-adhesive film on the back of the colloid 2. After being torn off, it can be used with the colloid 2 to complete the adhesive process.

[0025] like Figure 1 and Figure 2 As shown, the main adhesive layer 5 is laterally attached with an extrusion roller 9 along the intersection of the rear end of the colloid 2. The extrusion roller 9 can cooperate with manual rolling to complete the colloid 2 punching and adhesion process.

[0026] like Figure 1 and Figure 2 As shown, two sets of guide strips 4 are integrally connected to both sides of the main adhesive layer 5, and the inner end surfaces of the two sets of guide strips 4 are in guiding contact with the squeezing roller 9. The guide strips 4 serve as guides to prevent the squeezing roller 9 from shifting during the rolling process.

[0027] like Figure 1 and Figure 2 As shown, the ends of the main covering film 6 and the peeling film 12 are integrally connected with a pull ring 10. The main covering film 6 and the peeling film 12 can cooperate with the pull ring 10 to improve the operation experience.

[0028] like Figure 1 and Figure 2 As shown, the ends of the main adhesive layer 5 and the secondary adhesive layer 8 are integrally attached with a burr layer, and the main adhesive layer 5 and the secondary adhesive layer 8 are in a closed state of adhesion through the burr layer when not in use. The main adhesive layer 5 and the secondary adhesive layer 8 are attached to each other through the burr layer, which can play a protective role when not in use.
