Abstract

The invention discloses a novel crusted fire-resistant mica tape and a production process thereof. The novel crusted fire-resistant mica tape comprises enhanced protective layers, bonding layers and mica paper, wherein the enhanced protective layers are respectively arranged at the upper side and lower side of the mica paper through the bonding layers, and the bonding layer comprises waterborne ceramic silica gel and tritium trioxide. The novel crusted fire-resistant mica tape solves the technical problems of easy layering, easy breakage, no elasticity and environmental pollution of the fire-resistant mica tape in the prior art.

Description

technical field [0001] The invention relates to the technical field of wrapping materials in cables, in particular to a novel encrusted refractory mica tape and a manufacturing process thereof. Background technique [0002] At present, fire-resistant cables are made by covering the surface of the conductor with fire-resistant mica tape. Due to the high temperature resistance of the mica tape (the temperature resistance of natural phlogopite is about 850°C, and the temperature resistance of synthetic calcined mica is about 1100°C), so it is used for it. Special material for fire-resistant cables. At present, glass fiber cloth and film are used as protective reinforcement layer in the production of refractory mica tape, and diluted silica gel is used as adhesive to make glass fiber cloth, mica paper or film (PE or PET) through bonding and drying. , double-sided fire-resistant mica tape structure and single-sided fire-resistant mica tape structure, because the middle mica pape...
