Embodiment Construction

[0010] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.

[0011] Such as figure 1 and figure 2 As shown, a waterproof adhesive tape with an edge includes a tape base 5, a pressure-sensitive adhesive layer 4 is arranged below the tape base 5, and a release layer 2 is arranged below the pressure-sensitive adhesive layer 4. It is characterized in that the pressure-sensitive adhesive layer 4 Equal to the width of the release layer 2, the width of the tape base 5 is greater than the width of the pressure-sensitive adhesive layer 4, and the left edge 3 and the right edge 1 are arranged below the tape base 5 along its length direction, and the widths of the left edge 3 and the right edge 1 are equal. It is 5-8mm, and the cross-section of both is rectangular. The left edge 3 and the right edge 1 clamp the pressure-sensitive adhesive layer 4 and the release layer 2 in the middle.

Abstract

The invention relates to an edge-bearing waterproof adhesive tape which comprises a tape base, wherein a pressure-sensitive adhesive layer is arranged under the tape base, and a release layer is arranged under the pressure-sensitive adhesive layer. The waterproof adhesive tape is characterized in that the pressure-sensitive adhesive layer and release layer have the same width; the width of the tape base is greater than that of the pressure-sensitive adhesive layer; a left edge and a right edge are arranged below the tape base in the length direction; and the left edge and right edge clamp the pressure-sensitive adhesive layer and release layer in the middle. The edge-bearing waterproof adhesive tape can enable minimum water to contact with the bonding cement, and avoids impregnation of abundant water, thereby greatly prolonging the bonding time of the adhesive tape.

Description

technical field [0001] The invention belongs to a waterproof tape, in particular to a waterproof tape with edges. Background technique [0002] The waterproof tape is used in places with water. Ethylene-propylene rubber is used as the tape base, and the surface is coated with pressure-sensitive rubber cement, which can play a waterproof role and has a good bonding effect. However, even if waterproof materials are used, it is still necessary to avoid water impregnation of the cement as much as possible, otherwise, the bonding effect of the tape will still be affected after a long time. Contents of the invention [0003] Based on this, the object of the present invention is to provide a waterproof adhesive tape with an edge, which aims to avoid the impregnation of the cement by water as much as possible, so as to improve the bonding effect and bonding time of the tape. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: ...
