Description

Technical Field

[0001] This utility model belongs to the field of hot melt adhesive tape technology, specifically relating to a high-adhesion, water-resistant, environmentally friendly PUR hot melt adhesive tape. Background Technology

[0002] Hot melt adhesive tape mainly consists of a substrate and hot melt adhesive. When heated, the hot melt adhesive inside the tape melts and becomes fluid, allowing the tape to be applied to the surface of the object to be bonded. After the hot melt adhesive cools and solidifies, a strong adhesive layer is formed, thus achieving the bonding effect.

[0003] Tearing Deformation: During the tearing process of hot melt adhesive tape, it is difficult to maintain the integrity of the tape's shape due to the material and adhesiveness. Especially when the tearing angle or force is incorrect, the tape is prone to twisting, stretching, and other deformations, affecting its appearance and performance. Shearing Deformation: During the shearing process, if the tool used is not sharp enough or the shearing speed is too slow, the edges of the hot melt adhesive tape will become irregular or even curl. This deformation not only affects the appearance of the tape but may also reduce its adhesive effect. Moisture Penetration: Some hot melt adhesive tapes have poor water resistance and are prone to moisture penetration when exposed to water or humid environments. Moisture penetration can cause changes in the internal structure of the tape, thereby reducing its adhesive strength and durability. Poor Long-Term Water Resistance: Even if hot melt adhesive tape exhibits good water resistance in the short term, its water resistance may gradually decrease after long-term use due to environmental factors (such as temperature and humidity). Causes of air bubbles: Air bubbles are easily generated at the edges of hot melt adhesive tape due to improper handling during the cutting or tearing process. These air bubbles may be caused by air being trapped inside the tape or by poor adhesion between the tape and the substrate. Utility Model Content

[0023] Please see Figure 1-3 The technical solution provided in this embodiment is as follows:

[0024] A high-adhesion, water-resistant, environmentally friendly PUR hot melt adhesive tape, comprising:

[0025] Fusion layer 1;

[0026] A water-resistant component is disposed on the outer wall of the fusion layer 1, wherein: the water-resistant component includes a fiber layer 2, an adhesive layer 3, a film layer 4, a hot melt adhesive layer 6, a waterproof layer 7, and a reinforcing adhesive 9. The fiber layer 2 is sewn to the edge of the outer wall of the fusion layer 1, the adhesive layer 3 is bonded to both sides of the outer wall of the fiber layer 2 and the fusion layer 1, the hot melt adhesive layer 6 is bonded to both sides of the outer wall of the adhesive layer 3, the film layer 4 is attached to the outer wall of the hot melt adhesive layer 6, the waterproof layer 7 is sleeved on the outer wall of the hot melt adhesive layer 6, and the reinforcing adhesive 9 fills the openings in the inner wall of the fusion layer 1.

[0027] In a specific embodiment of this utility model, a multi-layer adhesive structure with water-resistant components is used: the setting of multiple layers such as fiber layer 2, adhesive layer 3, and hot melt adhesive layer 6 further enhances the bonding effect of the tape. The tight bond between these layers makes the tape less prone to detachment or breakage under external force. Waterproof layer 7 is designed: the waterproof layer 7 is fitted onto the outer wall of the hot melt adhesive layer 6, effectively preventing moisture from penetrating into the tape, thus ensuring the tape's water resistance. Coating layer 4 provides protection: the coating layer 4 is attached to the outer wall of the hot melt adhesive layer 6, not only enhancing the overall strength of the tape but also further improving its water resistance. Material preparation: Ensure that all component materials (fusion layer 1, fiber layer 2, adhesive layer 3, coating layer 4, hot melt adhesive layer 6, waterproof layer 7, and reinforcing adhesive 9) meet quality requirements, and prepare the necessary tools and equipment. Pretreatment: Pretreatment of the surfaces to be bonded, such as cleaning, degreasing, and dust removal, is performed to ensure the bonding effect. Positioning and Bonding: Apply the high-adhesion, water-resistant, and environmentally friendly PUR hot melt adhesive tape to the surfaces to be bonded according to the predetermined positions. Ensure that the fiber layer 2, adhesive layer 3, and hot melt adhesive layer 6 are correctly aligned and tightly bonded. Heating and Curing: PUR hot melt adhesive requires a specific temperature to cure; therefore, the tape needs to be heated. Heating can be achieved using a heat gun, oven, or other heating equipment to raise the tape to an appropriate temperature, causing the PUR hot melt adhesive to melt and flow. Applying Pressure: During the heating and curing process, apply pressure to the tape to promote full contact and wetting of the PUR hot melt adhesive with the bonded surfaces. This helps improve bond strength and water resistance.

[0028] Cooling: After heat curing, allow the tape to cool naturally or use a cooling device for rapid cooling. The purpose of cooling is to allow the PUR hot melt adhesive to cure quickly, forming a stable bond. Shaping: As the PUR hot melt adhesive cures, the tape will set into the desired shape and size. At this point, you can check whether the tape's adhesion and water resistance meet the requirements.

[0029] Specifically, an attraction layer 5 is deposited on the recessed inner wall of the coating layer 4.

[0030] In a specific embodiment of this utility model, the attraction layer 5 ensures the stability of the adhesion.

[0032] In a specific embodiment of this utility model, the tearing hole 8 allows for convenient tearing.

[0033] Specifically, the outer wall of the fusion layer 1 has a honeycomb-like opening.

[0034] In a specific embodiment of this utility model, the openings on the outer wall of the fusion layer 1 are honeycomb-shaped, which can ensure structural strength while improving lightweight.

[0035] Specifically, the attraction layer 5 and the adhesive layer 3 are matched with each other.

[0037] Specifically, the outer walls of the fusion layer 1 are recessed on both sides.

[0038] In a specific embodiment of this utility model, the outer walls of the fusion layer 1 are recessed on both sides to facilitate the flow and injection of the reinforcing adhesive 9.

[0039] Working principle:

[0040] The tape utilizes a multi-layered adhesive structure with water-resistant components: The multi-layered structure, including fiber layer 2, adhesive layer 3, and hot melt adhesive layer 6, further enhances the tape's bonding effect. The tight bond between these layers prevents the tape from easily detaching or breaking under external force. Waterproof layer 7 is designed to fit over the outer wall of the hot melt adhesive layer 6, effectively preventing moisture penetration into the tape and ensuring its water resistance. A protective coating layer 4 adheres to the outer wall of the hot melt adhesive layer 6, enhancing both the overall strength and water resistance of the tape. Material preparation: Ensure all components (fusion layer 1, fiber layer 2, adhesive layer 3, coating layer 4, hot melt adhesive layer 6, waterproof layer 7, and reinforcing adhesive 9) meet quality requirements and prepare the necessary tools and equipment. Pre-treatment: Pre-treat the surfaces to be bonded, such as cleaning, removing oil and dust, to ensure effective bonding. Positioning and application: Apply the high-adhesion, water-resistant, environmentally friendly PUR hot melt adhesive tape to the surfaces to be bonded according to the predetermined positions. Ensure the fiber layer 2, adhesive layer 3, and hot melt adhesive layer 6 are correctly aligned and tightly bonded. Heating and curing: PUR hot melt adhesive requires a specific temperature to cure; therefore, the tape needs to be heated. Heating can be done using a heat gun, oven, or other heating equipment to raise the tape to an appropriate temperature, causing the PUR hot melt adhesive to melt and flow. Applying pressure: During the heating and curing process, a certain amount of pressure can be applied to the tape to promote full contact and wetting of the PUR hot melt adhesive with the bonded surfaces. This helps improve bond strength and water resistance.
