Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-4, a double faced adhesive tape with waterproof edge strips comprises a double faced adhesive tape main body 1, wherein the double faced adhesive tape main body 1 comprises a base layer 2, the upper surface and the bottom surface of the base layer 2 are respectively provided with a first adhesion layer 3, the width of the first adhesion layer 3 is smaller than that of the base layer 2, the first adhesion layer 3 is positioned in the middle of the base layer 2, the two ends of the upper surface and the bottom surface of the base layer 2 are respectively provided with absorbent cotton 4, and the absorbent cotton 4 is positioned on two sides of the first adhesion layer 3.
Referring to fig. 1-3, the double-sided tape structure of the present utility model is similar to the existing double-sided tape structure, such as the double-sided tape with waterproof edge strips disclosed in the patent with publication No. CN216039383U, and the main improvement of the present utility model is that the waterproof property of the double-sided tape can be increased; when the double-sided adhesive tape main body 1 is used, the base layer 2 connects the two first adhesion layers 3, two objects are bonded through the two first adhesion layers 3, when water flows to the double-sided adhesive tape main body 1, the two absorbent cottons 4 on two sides of the first adhesion layers 3 can absorb the water, so that the water cannot flow to the first adhesion layers 3, the phenomenon that the first adhesion layers 3 can not adhere the objects due to the fact that the viscosity is reduced when the first adhesion layers 3 meet water is avoided, and the waterproof performance is improved.
Referring to fig. 3 and 4, a second adhesion layer 5 is disposed on a side of the absorbent cotton 4 away from the base layer 2, a water inlet hole 6 is formed through one side of the second adhesion layer 5, when the double faced adhesive tape main body 1 bonds two objects, the first adhesion layer 3 and the second adhesion layer 5 bond the objects, and when water is encountered, the absorbent cotton 4 absorbs water through the water inlet hole 6, and the phenomenon of edge warping of the absorbent cotton 4 due to unlimited use of the second adhesion layer 5 is avoided, and the connection strength of the two objects is increased.
Referring to fig. 3 and 4, the water inlet holes 6 are multiple groups, the multiple groups of water inlet holes 6 are uniformly distributed on the second adhesive layer 5, and as the water contacts with the second adhesive layer 5 more and more, the viscosity of the second adhesive layer 5 gradually decreases, through the multiple groups of water inlet holes 6, water flows from the water inlet holes 6 on the outermost layer to pass through the absorbent cotton 4 for absorption, if the viscosity of the outer layer of the second adhesive layer 5 decreases, the water flows from the water inlet holes 6 from outside to inside to pass through the absorbent cotton 4 for absorption, so that the viscosity of the second adhesive layer 5 decreases in a part of the area after meeting water, and the viscosity decreasing speed of the second adhesive layer 5 after meeting water can be reduced, thereby increasing the overall waterproof property.
