AI Technical Summary

Technical Problem

Ordinary Teflon tapes have limitations in terms of strength, making them unsuitable for some scenarios that require high tape strength, thus reducing their practicality.

Method used

It adopts a multi-layer composite structure, including a surface fireproof protective layer, a fireproof barrier layer, a Teflon main layer, an aramid fiber reinforcement layer, and a bottom adhesive layer. The strength is improved by the design of the fireproof polyimide film and the fireproof barrier layer and the aramid fiber reinforcement layer, and a porous foam carbonized layer is formed in high temperature or flame environment to prevent heat transfer.

Benefits of technology

It significantly improves the tensile strength and tear resistance of the tape, and has excellent fire-retardant properties. It is suitable for industrial fireproof sealing in complex environments, installation of building fire protection facilities, fireproof wrapping of power cables, and protection of household kitchen appliances and high-temperature equipment.

Abstract

This utility model relates to the field of Teflon tape technology, specifically disclosing a multi-layer composite reinforced Teflon tape, including a surface fire-resistant protective layer, a fire-resistant barrier layer disposed below the surface fire-resistant protective layer, a Teflon main body layer disposed below the fire-resistant barrier layer, an aramid fiber reinforcement layer connected to the lower surface of the Teflon main body layer, and a bottom adhesive layer fixedly connected to the lower surface of the aramid fiber reinforcement layer. This multi-layer composite reinforced Teflon tape, with its aramid fiber reinforcement layer, effectively improves the tensile strength of the tape compared to ordinary Teflon tape and significantly enhances its tear resistance. The fire-retardant design of each layer includes a fire-retardant polyimide film, fire-retardant treated aramid fibers, an optimized Teflon main body layer, an intumescent fire-retardant coating, and an adhesive with added flame-retardant components, giving the tape excellent fire-retardant properties, effectively resisting flame attack and preventing the spread of fire.
