Description
Technical Field
The invention belongs to the field of electrical insulating materials, and particularly relates to an ultra-wide winding mica tape with any length and a manufacturing method thereof.
Background
The mica tape for the fire-resistant safety cable is a strip-shaped insulating material which is formed by taking heat-resistant insulating mica paper as a base material, taking electronic grade alkali-free glass fiber cloth (or a film and the like) as a reinforcing material, impregnating the base material with a high-temperature organic silicon adhesive, compounding, baking and cutting the impregnated base material, and wrapping the mica tape on a core wire by a wrapping machine, so that a finished cable product can keep safe operation for a certain time under the condition of flame combustion.
The ultra-wide mica tape mainly refers to a mica tape with the width of more than 20mm, is usually used for wrapping cables with larger wire diameters, is mainly used for wrapping mica tapes of insulating cores such as control cables and optical cables, has the wrapping layers from double layers to more than six layers, and is mainly used in places such as power plants, airports, ships, high-rise buildings and subways, and the demand is increased day by day. Due to the limitation of wrapping equipment, the length of the existing single-coil ultra-wide mica tape is limited, and generally, each coil is within 1000m, so that a client stops and is frequently butted when wrapping, and the quality and the production efficiency of a cable are seriously influenced. Meanwhile, the ultra-wide mica tapes are cut in a single-disc mode at present, and the longest length of a single-disc product cannot exceed 1000 m.

After the width of the mica tape is increased, the more the allowance of the mica tape at the deflection side is, the more easily the mica tape is wrinkled, so that the quality problems of frequent tape breakage and the like in the process of cable wrapping are caused, meanwhile, along with the wider mica tape, the larger the tension required to be provided and the pressure of the winding arm are, the larger the winding difficulty is, and the conventional winding mode is generally suitable for winding the mica tape with the width of 20mm or below.
