Description

Technical Field

[0001] The utility model relates to the technical field of foam adhesive backing, in particular to a foam adhesive backing with an inner concave waterproof pasting structure. Background Art

[0002] Foam is a material made of foamed plastic particles, referred to as foam. With the rapid development of social economy, the use of foam adhesive is becoming more and more extensive. Foam adhesive can be used to quickly stick two objects together, so it is widely used in various industries.

[0003] A foam adhesive disclosed in the Chinese utility model patent application disclosure specification CN208266108U has at least one connecting half-punched line on the front release film, and a connecting point is retained on the connecting half-punched line, so that it is convenient to tear off the front release film that needs to be torn off, and the part of the front release film that needs to be bonded first can be torn off, and the remaining front release film can be retained. When it needs to be bonded in another step, the remaining front release film can be torn off to prevent dust and other foreign matter from being stuck on the unbonded foam adhesive layer, thereby ensuring the assembly of other components. However, the foam back adhesive itself has a poor moisture-proof effect. Affected by humid water vapor, it is easy to reduce the bonding effect of the foam back adhesive, thereby failing to effectively play a role in stable bonding between objects. Utility Model Content

[0004] The utility model aims to provide a foam adhesive with a concave waterproof adhesive structure to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a foam backing adhesive with an inwardly concave waterproof adhesive structure, comprising a waterproof film, a foam layer, an adhesive glue and an adhesive film, wherein the foam layers are connected to both sides of the waterproof film, and the waterproof film and the foam layer are fixedly connected, and a tough layer is connected to the middle position of the foam layer, and the foam layer and the tough layer are fixedly connected.

[0006] Preferably, it is characterized in that: one side of the foam layer is connected with adhesive glue, and the foam layer and the adhesive glue are fixedly connected.

[0007] Preferably, an adhesive film is connected to one side of the adhesive glue, and the adhesive glue and the adhesive film are movably connected.

[0008] Preferably, a through groove is provided inside one side of the adhesive film, wear-resistant particles are evenly and equidistantly provided on the top of the adhesive film, and the adhesive film and the wear-resistant particles are fixedly connected.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. The foam adhesive with the concave waterproof adhesive structure can effectively cover the foam layer by setting two sets of grooves on both sides of the waterproof film. At the same time, the waterproof film is made of polyurethane plastic material, which can effectively waterproof the outside of the foam layer. The foam layer is made of polypropylene plastic material, which effectively improves the corrosion resistance of the foam adhesive, thereby effectively ensuring the overall use effect of the foam adhesive;

[0011] 2. The foam adhesive with a concave waterproof adhesive structure has an adhesive film on one side of the adhesive, and two groups of through grooves are provided on the contact surface between the adhesive film and the adhesive. The through grooves can reduce the contact area between the entire adhesive film and the adhesive, thereby reducing consumables and facilitating the rapid tearing of the adhesive film from the surface of the adhesive. At the same time, multiple groups of wear-resistant particles are provided on the outside of the adhesive film to increase the overall wear resistance of the foam adhesive, reduce the loss of the foam adhesive, increase the friction between the foam adhesive and the hand, and improve the stability of the foam adhesive grip.
