Description

Technical Field

[0001] The utility model belongs to the technical field of adhesive tapes, and in particular relates to a fireproof adhesive tape. Background Art

[0002] Adhesive tape is composed of a base material and an adhesive, etc., and is used to connect objects together through bonding, or to adhere to the surface of an object for protection. In some applications with fire protection requirements, the adhesive tape is required to have flame retardant and fireproof functions. For this purpose, a functional layer such as a fire retardant is usually coated on the surface of the tape base material, so that the tape has a fire retardant function. At the same time, in order to facilitate transportation and storage, the tape products used by users usually also have structures such as an installation tube, and the tape base material is wound on the installation tube to form a roll.

[0003] When using some existing fireproof tape products, a section of the tape needs to be cut after being pulled out. When using it next time after cutting, it is necessary to find the cut point again and hold up the edge with fingers. This method makes it inconvenient to take out the tape and affects work efficiency. In addition, since the tape substrate also has a fire-retardant and other functional layers, when holding up the edge of the tape with fingers, it is easy to peel off the functional layer at the edge of the tape, causing the functional layer to separate from the substrate, and the section of tape after the separation needs to be discarded, resulting in waste of tape.

[0004] In view of this, the present utility model is proposed. Utility Model Content
