Problems solved by technology

And use the metal-plastic composite tape that existing this plastic film is made, because the bonding between the outer sheath layer and the metal-plastic composite tape is quite firm when construction is erected, it is difficult to remove the sheath layer from the metal-plastic composite tape Stripping and removing completely affects the progress of the construction and erection of the optical cable. At the same time, it also causes the core and other materials of the optical cable to not be reused, resulting in waste.

Abstract

The invention relates to a plastic film with a layering control function and a preparation method thereof. The plastic film comprises a bonding layer, an easy-to-tear layer and a stripping layer, wherein the bonding layer is prepared from ethylene-acrylic acid copolymer or ethylene-methacrylic acid copolymer; the easy-to-tear layer is prepared from a blend formed by mixing ethylene-vinyl acetate copolymer, ethylene-methacrylic acid ionic polymer, poly-1-butene, silicon dioxide, beta-propionic acid octade, triphenyl phosphite, N,N'-ethylenebisoctadecanamide, 2,6-Di-tert-butyl-4-methylphenol, oleamide, triphenyl phosphate and oleyl palmitamide according to a certain weight ratio; the stripping layer is prepared from a blend formed by mixing ethylene-vinyl acetate copolymer, low-density polyethylene and a linear low-density polyethylene resin material according to a certain weight ratio. The plastic film with the layering control function ensures that an external sheath layer of an optical cable or an electric cable can be disengaged from the bonding layer and also ensures that a metal-plastic composite belt is free of moisture invasion.

Description

technical field [0001] The invention relates to a communication material, in particular to a plastic film for making an optical cable or a cable shielding layer and a preparation method thereof, belonging to the field of communication materials. Background technique [0002] The overall structure of the optical cable can be divided into three parts: the cable core, the shielding layer (that is, the metal-plastic composite tape layer), and the sheath layer. Among them, the cable core is used for signal transmission; the shielding layer is made of metal-plastic composite tape material, and the cable core is tightly wrapped by the metal-plastic composite tape longitudinally to make it airtight. It plays the role of shielding, armoring, anti-corrosion, and moisture-proof; the sheath layer is made of a polyethylene plastic material, which is melted at a certain temperature and tightly adhered to the plastic on the surface of the metal-plastic composite tape by extrusion Knotted ...
