AI Technical Summary

Technical Problem

The existing edge sealing tape is not waterproof enough. Rainwater can easily seep through the side of the edge sealing tape and come into contact with the adhesive layer, causing water to enter the adhesive layer and separate from the material, resulting in problems such as edge curling or peeling.

Method used

The waterproof layer is made of ethylene propylene rubber, combined with a PVC substrate layer, and features sloping edges and connecting holes. It is also equipped with a highly absorbent resin water-absorbing layer and a sponge layer to form a multi-layer structure to enhance waterproofness and stability.

Benefits of technology

It effectively prevents water penetration, with the sponge layer quickly absorbing moisture and the absorbent layer promptly removing excess moisture, thus improving the waterproof effect and stability of the tape and preventing water retention from damaging the adhesive's adhesion.

Abstract

本实用新型属于胶带技术领域，尤其为一种高阻水封边胶带，包括基材层，所述基材层的顶部设置有防水层，所述防水层的底部设置有胶水层，所述基材层的两侧设置有对称分布的吸水层，所述吸水层的底部设置有海绵层，所述海绵层位于防水层的两侧，所述防水层采用乙丙橡胶作为原材料制作而成。该一种高阻水封边胶带，通过防水层的设计可以很好地防水来自胶带顶部的水渗透，通过海绵层与吸水层的设计，在胶带侧边沾水时，海绵层可快速将水吸附，同时吸水层将海绵层内的水吸走，从而使得水远离胶水层，如此极大地提高封边胶带的防水效果，避免水滞留在胶水层的两侧对胶水的粘性造成破坏。
