Abstract
Description
Technical Field
[0001] This utility model relates to the field of sealing strip technology, specifically a self-adhesive sealing strip. Background Technology
[0002] Self-adhesive sealing strips are made of materials such as rubber, plastic, or sponge and have a self-adhesive backing. This design makes them widely used in building doors and windows, curtain walls, automotive interiors, and various household appliances. They can easily adhere to various sealing areas and not only possess the excellent sealing performance of ordinary sealing strips, effectively resisting air, moisture, and dust, but also reduce energy consumption to a certain extent due to their excellent thermal insulation properties. The biggest advantage of self-adhesive sealing strips is that installation requires no additional tools or complicated procedures; simply peel off the release paper for a secure bond, greatly saving installation time and labor costs. They provide a simple and efficient solution for improving the sealing quality of living and industrial environments.
[0003] Current self-adhesive sealing strips suffer from adhesion problems when dust or water droplets are present at the application site. This prevents the sealing strip from adhering tightly to the substrate, reducing its strength and sealing performance. To address this, we propose a new type of self-adhesive sealing strip. Utility Model Content
[0004] The purpose of this invention is to provide a self-adhesive sealing strip that allows for the removal of water droplets and dust from the surface of the object to be adhered to before the sealing strip is bonded to the adhesive layer. This improves the tightness between the self-adhesive layer and the object, thereby enhancing the adhesion and sealing performance of the sealing strip. This solves the problem that current self-adhesive sealing strips, when dust or water droplets are present at the desired adhesion point, hinder adhesion, preventing a tight bond between the sealing strip and the object, thus reducing the adhesion and sealing performance of the sealing strip.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-adhesive sealing strip, comprising a sealing strip body and a self-adhesive layer, wherein the self-adhesive layer is disposed on the upper surface of the sealing strip body, a first release film layer is disposed on the upper surface of the self-adhesive layer, a dust-repellent adhesive layer is disposed on the upper surface of the first release film layer, a second release film layer is disposed on the upper surface of the dust-repellent adhesive layer, and a water-absorbing layer is disposed on the upper surface of the second release film layer.
[0006] Preferably, an adhesive strip is provided on the upper surface of the second isolation film layer near the edge. A sealing film layer is provided on the upper surface of the adhesive strip, and the absorbent layer is located between the sealing film layer and the second isolation film layer. The absorbent layer is sealed between the sealing film layer and the second isolation film layer by the sealing film layer and the adhesive strip to prevent water absorption and exposure, thus preventing the absorbent layer from easily absorbing moisture and reducing its water absorption performance.
[0007] Preferably, one end of the sealing film layer is provided with a third extension, which facilitates the removal of the sealing film layer.
[0008] Preferably, a first extension is provided at one end of the first isolation film layer, which facilitates the removal of the first isolation film layer.
[0009] Preferably, one end of the second isolation film layer is provided with a second extension portion, which facilitates the removal of the second isolation film layer.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] 1. This utility model, by setting up a sealing strip body, a self-adhesive layer, a first release film layer, a dust-repellent adhesive layer, a second release film layer, and a water-absorbing layer, achieves the effect of facilitating the removal of water droplets and dust from the surface of the object to be adhered to before the sealing strip is adhered to the adhesive layer, thereby improving the tightness between the self-adhesive layer and the object, and thus improving the adhesion and sealing performance of the sealing strip. Before the sealing strip is adhered, the water-absorbing layer absorbs the moisture on the adhesion area of the object, making the adhesion area dry. Then, the second release film layer is removed, and the dust-repellent adhesive layer absorbs the dust and impurities on the adhesion area. Finally, the first release film layer is removed, and the sealing strip body adheres to the adhesion area of the object through the self-adhesive layer.
[0012] 2. This utility model achieves the effect of preventing the absorbent layer from absorbing moisture and reducing its water absorption performance by setting adhesive strips and sealing film layers. By sealing the absorbent layer between the sealing film layer and the second isolation film layer through the sealing film layer and adhesive strips, the absorbent layer is prevented from being exposed and thus its water absorption performance is prevented from being reduced due to absorbing moisture.

[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0017] Example 1
[0018] like Figure 1 and Figure 2 As shown, this utility model proposes a self-adhesive sealing strip, comprising a sealing strip body 1 and a self-adhesive layer 2. The self-adhesive layer 2 is disposed on the upper surface of the sealing strip body 1, and the sealing strip body 1 is adhered to the object through the self-adhesive layer 2. A first release film layer 3 is disposed on the upper surface of the self-adhesive layer 2, which acts as a sealant to prevent dust, impurities, etc. from adhering to the self-adhesive layer 2 and reducing its adhesive performance. A dust-adhesive layer 4 is provided on the upper surface of layer 3. The dust-adhesive layer 4 can adhere to and remove dust and impurities on the adhesive. A second release film layer 5 is provided on the upper surface of the dust-adhesive layer 4. The second release film layer 5 seals the dust-adhesive layer 4, preventing dust and impurities from adhering to the dust-adhesive layer 4 and reducing the adhesion performance of the dust-adhesive layer 4 to dust and impurities on the adhesive. A water-absorbing layer 6 is provided on the upper surface of the second release film layer 5. The water-absorbing layer 6 is a water-absorbing material such as absorbent paper, which can absorb the moisture on the adhesive.
[0019] Before the sealing strip body 1 is pasted, the water-absorbing layer 6 absorbs the moisture on the pasting part of the object, making the pasting part dry. Then, the second release film layer 5 is removed, and the dust-adhesive layer 4 absorbs the dust and impurities on the pasting part. Finally, the first release film layer 3 is removed, and the sealing strip body 1 adheres to the pasting part of the object through the self-adhesive layer 2, thereby improving the tightness and firmness between the self-adhesive layer 2 and the object, thus improving the adhesion firmness and sealing performance of the sealing strip body 1.
[0020] Example 2
[0021] like Figure 1As shown, the self-adhesive sealing strip proposed in this utility model, compared with Embodiment 1, further includes an adhesive strip 7 disposed on the upper surface of the second isolation film layer 5 near the edge, a sealing film layer 8 disposed on the upper surface of the adhesive strip 7, and an absorbent layer 6 located between the sealing film layer 8 and the second isolation film layer 5. A third extension 11 is disposed at one end of the sealing film layer 8, a first extension 9 is disposed at one end of the first isolation film layer 3, and a second extension 10 is disposed at one end of the second isolation film layer 5. The first extension 9, the second extension 10 and the third extension 11 facilitate the removal of the first isolation film layer 3, the second isolation film layer 5 and the sealing film layer 8.
[0022] In this embodiment, the absorbent layer 6 is sealed between the sealing film layer 8 and the second isolation film layer 5 by the sealing film layer 8 and the adhesive strip 7 to prevent the absorbent layer 6 from being exposed, thus preventing the absorbent layer 6 from reducing its water absorption performance due to absorbing moisture.
[0023] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
