Description

Waterproof foam adhesive tape

Technical Field

The application relates to the technical field of adhesive tape correlation, in particular to a waterproof foam adhesive tape.

Background

The adhesive tape is composed of two parts of a substrate and an adhesive, and is a multi-layer composition capable of bonding two or more unconnected objects together. The adhesive on the adhesive tape is generally a pressure-sensitive adhesive, and various materials which can be present in the form of a roll can be used as a base material of the adhesive tape, such as organic films, nonwoven fabrics/flannelette base materials, and the like.

The foam adhesive tape is manufactured by using EVA (ethylene vinyl acetate) or PE (polyethylene) foam as a base material, coating a solvent type (or hot melt type) pressure-sensitive adhesive on one surface or two surfaces of the base material and then compounding release paper. Due to the particularity of the base material, the adhesive tape has the functions of shock resistance, buffering, lasting elasticity and excellent sealing performance which are not possessed by the common adhesive tape.

The side and the end of the related foam adhesive tape on the market are not sealed well after being unsealed, so that dust, slag and water are easily adhered to the two sides and the end of the unused silica gel tape after being unsealed, the adhesive effect of the adhesive tape is influenced, and the normal use of the adhesive tape is influenced.

SUMMERY OF THE UTILITY MODEL

In order to improve the sealing performance of foam adhesive tape side and tip, this application provides a waterproof foam adhesive tape.

The application provides a waterproof foam adhesive tape, adopts following technical scheme:

a waterproof foam adhesive tape comprises an adhesive tape body, wherein the adhesive tape body comprises a first waterproof layer, a foam layer and an adhesive layer, one side of the adhesive tape body, which is close to the first waterproof layer, is an upper side, one side of the adhesive tape body, which is close to the adhesive layer, is a lower side, the upper side of the first waterproof layer and the lower side of the adhesive layer are both provided with first release layers, and the left side and the right side of the adhesive tape body are both provided with second release layers; pre-breaking lines are arranged between the two sides of the second release layer and the first release layer; the second release layer comprises a plurality of second release sections which are connected end to end, and two adjacent second release sections are clamped and connected; the length of each second release section is consistent with the width of the first release layer.
