Description

Technical Field

[0001] The utility model relates to the field of adhesive backing, in particular to highly breathable and high-strength adhesive backing. Background Art

[0002] Adhesive is a kind of adhesive material, which is widely used for pasting various materials and surfaces, especially for pasting advertisements. Since the adhesive is not breathable, the air in the adhesive is discharged slowly during the pasting process, which easily generates bubbles after the adhesive is pasted. If it is peeled off and pasted again, its stickiness will be affected, resulting in poor pasting effect. If the bubbles are squeezed out of the adhesive, it is difficult to squeeze out the bubbles due to the large adhesive area of ​​the advertisement, and it is even easy to scratch the advertisement. Utility Model Content

[0003] The purpose of the utility model is to provide a highly breathable and high-strength adhesive to overcome the above-mentioned defects in the prior art.

[0005] Through the above technical scheme, when the glue layer is pasted, it is connected with the outside world through the ventilation groove, so as to reduce the generation of bubbles between the glue layer and the adhered object. At the same time, a plurality of ventilation grooves can divide the glue layer into a plurality of areas. If bubbles are generated in one of the areas, the air in the bubbles in the area can be easily squeezed into the ventilation groove, which is conducive to the elimination of the bubbles.

[0006] The utility model is configured as follows: a plurality of ventilation grooves are interlaced and connected with each other to form a grid shape.

[0007] Through the above technical solution, the plurality of ventilation grooves can divide the glue layer into a plurality of areas of equal size, which can not only effectively reduce the generation of bubbles but also facilitate the extrusion of the generated bubbles.

[0008] The utility model is arranged that: the two ends of the ventilation groove are contracted inwardly to form an exhaust port, so that the ventilation groove forms a structure with a wide middle section and narrow ends.

[0009] Through the above technical solution, the exhaust port formed by shrinkage can not only be used for exhaust but also reduce the dust from entering the ventilation groove through the exhaust port. Meanwhile, the width of the middle section of the ventilation groove is conducive to the discharge of bubbles in the middle of the glue layer.

[0010] The utility model is configured as follows: the glue layer is one of epoxy resin glue, polyurethane glue or organic silica gel water.

[0011] Through the above technical solution, the viscosity of the glue layer is high and the consistency is large, ensuring that the glue layer maintains a stable shape during the pasting process.

[0012] The utility model is configured as follows: a reinforcement layer located on the upper side of the ventilation groove is fixed in the glue layer.

[0013] Through the above technical solution, the reinforcing layer can enhance the tensile strength of the glue layer, further ensuring its stable shape during pasting.

[0014] The utility model is arranged that: the reinforcing layer is in a mesh shape made of polyester fibers.

[0015] Through the above technical solution, the mesh reinforcement layer can be immersed and fixed in the glue layer, the glue layer completely wraps the reinforcement layer, and the polyester fiber has high strength and durability, which can effectively enhance the tensile and tear strength of the back glue.

[0016] The utility model has the following beneficial effects: when the glue layer is pasted, it is connected with the outside world through the ventilation groove, so as to reduce the generation of bubbles between the glue layer and the adhered object; at the same time, a plurality of ventilation grooves can divide the glue layer into a plurality of areas; if bubbles are generated in one of the areas, the air in the bubbles in the area can be easily squeezed into the ventilation groove, so as to be conducive to the elimination of the bubbles; and the reinforcing layer made of polyester fiber has high strength and durability, and can effectively enhance the tensile and tearing strength of the back adhesive.
