Description

Technical Field

[0001] This utility model relates to the field of highway maintenance technology, and in particular to asphalt joint tape with self-adhesive layer. Background Technology

[0002] Asphalt crack sealing tape with a self-adhesive layer is a self-adhesive road maintenance material used for sealing cracks. It is waterproof, anti-aging, and easy to apply, requiring no heating before application.

[0003] Traditional asphalt joint sealant with a self-adhesive layer consists of an asphalt surface layer, a reinforcing layer, a self-adhesive layer, and a release layer. The release layer protects the self-adhesive layer and prevents it from adhering to other objects. However, when workers attempt to peel off the release layer, its edges are difficult to remove because they are adhered to the self-adhesive layer, increasing the workload for workers. Therefore, this solution proposes an asphalt joint sealant with a self-adhesive layer to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide an asphalt joint sealant with a self-adhesive layer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an asphalt joint sealant with a self-adhesive layer, comprising:

[0006] Asphalt surface layer;

[0007] The reinforcing part is disposed at the bottom of the asphalt surface layer;

[0008] An adhesive layer is disposed at the bottom of the reinforcing part and is used to fix the position of the asphalt surface layer;

[0009] A first isolation section includes a first release paper disposed at the bottom of the adhesive layer, the first release paper being used to protect the adhesive layer, and a separation member for separating the first release paper from the adhesive layer being disposed in the middle of the first isolation section;

[0010] The second isolation section includes a second release paper fixedly connected to the bottom of the first release paper, and a pulling part for pulling the first release paper is provided in the middle of the second release paper.

[0011] Preferably, the reinforcing part includes a geotextile disposed on top of the adhesive layer, and a waterproof layer is disposed on top of the geotextile.

[0012] Preferably, an antibacterial layer is provided on top of the waterproof layer, a heat insulation layer is provided on top of the antibacterial layer, and the heat insulation layer is provided at the bottom of the asphalt surface layer.

[0013] Preferably, the separating element includes a through hole formed in the middle of the first release paper, and a third release paper is inserted and connected inside the through hole, the third release paper being disposed at the bottom of the adhesive layer.

[0014] Preferably, the pulling part includes a mounting groove formed in the middle of the second release paper, and a pulling paper is fixedly connected to the inner wall of one side of the mounting groove.

[0015] Preferably, the horizontal longitudinal section of the third release paper is set as an equilateral trapezoid, and the horizontal longitudinal section of the pull paper is set as a right trapezoid.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] This invention utilizes a design comprising a first release paper, a separating component, a second release paper, and a pulling component. During use, the first and second release papers are fixedly connected. When it is necessary to separate the first release paper from the adhesive layer, the pulling component pulls the second and first release papers, causing the first release paper to move away from the adhesive layer. This separation also causes the adhesive layer to move away from the first release paper, thereby separating the adhesive layer from the release paper and reducing the time required for workers to peel off the release paper.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides, for example Figure 1 The self-adhesive asphalt joint tape shown includes:

[0022] Asphalt surface layer 1;

[0023] The reinforcement section is located at the bottom of the asphalt surface layer 1;

[0024] Adhesive layer 6 is disposed at the bottom of the reinforcing part and is used to fix the position of the asphalt surface layer 1.

[0025] The first isolation section 7 includes a first release paper 701 disposed at the bottom of the adhesive layer 6. The first release paper 701 is used to protect the adhesive layer 6. A separating member for separating the first release paper 701 from the adhesive layer 6 is disposed in the middle of the first isolation section 7.

[0026] The second isolation section 8 includes a second release paper 801 fixedly connected to the bottom of the first release paper 701, and a pulling part for pulling the first release paper 701 is provided in the middle of the second release paper 801.

[0027] It should be noted that the asphalt surface layer 1 is composed of asphalt and various additives; the adhesive layer 6 is made of existing high-viscosity modified asphalt material, which has self-adhesive properties at room temperature and can firmly bond to cracks without heating; the first release paper 701 and the second release paper 801 are both existing silicone oil papers. The opposite sides of the two are first wiped with alcohol to remove silicone oil and dust, and then the two are fixed together by adhesive to protect the adhesive layer 6 and reduce dust from being adhered to the adhesive layer 6.

[0028] Furthermore, during use, the first release paper 701 and the second release paper 801 are fixedly connected. When it is necessary to separate the first release paper 701 from the adhesive layer 6, the second release paper 801 and the first release paper 701 are pulled by the pulling member, so that the first release paper 701 moves away from the adhesive layer 6. The separation causes the adhesive layer 6 to move away from the first release paper 701, thereby separating the adhesive layer 6 and the release paper.

[0029] Specifically, the reinforcing part includes a geotextile 5 placed on top of the adhesive layer 6, and a waterproof layer 4 is placed on top of the geotextile 5.

[0030] It should be noted that the geotextile 5 uses polyester staple fiber needle-punched geotextile 5 to isolate the joint tape materials with different physical properties, so that the two or more materials do not leak or mix, maintain the overall structure and function of the materials, strengthen the load-bearing capacity of the joint tape, and extend the service life of the joint tape; the waterproof layer 4 is made of synthetic rubber and is used to prevent water from seeping downwards during use.

[0031] Specifically, an antibacterial layer 3 is provided on top of the waterproof layer 4, a heat insulation layer 2 is provided on top of the antibacterial layer 3, and the heat insulation layer 2 is provided at the bottom of the asphalt surface layer 1.

[0032] It should be noted that the heat insulation layer 2 is made of polyurethane foam, which is used to prevent heat from being transmitted downwards. The asphalt surface layer 1 on top will absorb heat during long-term traffic or when exposed to direct sunlight in summer, thus preventing the bottom layer of the heat insulation layer 2 from being damaged by high temperature due to heat transmission downwards. The antibacterial layer 3 is made of zinc oxide, which inhibits the growth of microorganisms in the cracks, prevents material degradation caused by biological corrosion, and reduces secondary pavement damage caused by microbial activity in long-term humid environments, thereby extending the service life of the joint sealing strip.

[0033] Specifically, the separating component includes a through hole 702 opened in the middle of the first release paper 701, and a third release paper 703 is inserted and connected inside the through hole 702. The third release paper 703 is disposed at the bottom of the adhesive layer 6. The pulling part includes a mounting groove 802 opened in the middle of the second release paper 801, and a pulling paper 803 is fixedly connected to the inner wall of one side of the mounting groove 802. The horizontal longitudinal section of the third release paper 703 is set as an equilateral trapezoid, and the horizontal longitudinal section of the pulling paper 803 is set as a right trapezoid.

[0034] It should be noted that the through hole 702 is adapted to the third release paper 703, so that the third release paper 703 can be inserted into the through hole 702. When making the second release paper 801, the U-shaped groove is directly cut out by cutting, so that the pull paper 803 is directly formed by cutting. The horizontal longitudinal section of the third release paper 703 is set as an equilateral trapezoid, so that its edge cannot contact the adhesive layer 6, so that it can be directly peeled off from the adhesive layer 6 by pulling the edge of the third release paper 703.

[0035] Furthermore, in use, first remove the release paper 803 from the inside of the mounting groove 802, pull it with one hand, and then put the other hand through the mounting groove 802 to push the third release paper 703 to one side of the adhesive layer 6, thereby separating the first release paper 701 from the adhesive layer 6. Finally, remove the third release paper 703 from the adhesive layer 6.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
