Problems solved by technology

[0002] In the current technical application, the outer layer of the plastic film composite tape is only compounded with a layer of plastic film of about 0.05mm. It is a one-time composite paste of the plastic film on the two surfaces of the metal foil and the tape through a high-temperature process. The compounded metal foil and plastic film with one side can form the effect of separating the double-layer plastic film by peeling off, and the bonding strength between the plastic film and the metal foil and tape cannot be fully guaranteed, resulting in poor corrosion resistance and long service life of the composite tape. short

Embodiment 1

[0019] Embodiment 1: as figure 1 Shown, a kind of double-layer plastic film composite tape, it comprises strip-shaped metal foil 1, the inner layer plastic film 2 of 0.025mm thickness and the outer layer plastic film 3 of 0.025mm thickness are composited on the outer surface of metal foil. The inner plastic film 2 and the outer plastic film 3 all adopt polyethylene plastic film.

Embodiment 2

[0020] Embodiment 2: a kind of preparation method of double-layer plastic film composite tape, it comprises the following steps successively: (1) strip-shaped metal foil is preheated through preheating zone and hot drum heating zone before compounding, and metal foil surface temperature reaches 120°C; (2) Extrude and compound the inner plastic film on the two surfaces of the strip-shaped metal foil through two horizontal rubber rollers; (3) After compounding, the heating zone is cured to make the surface temperature of the inner plastic film reach 60° C.; (4) Extrude and compound the outer layer of plastic film to the two surfaces of the inner layer of plastic film through two horizontal rubber rollers.

Embodiment 3

[0021] Embodiment 3: a kind of preparation method of double-layer plastic film compound tape, it comprises the following steps successively: (1) strip-shaped metal foil is passed through the preheating of heating zone before compounding and hot drum heating zone, makes metal foil surface temperature reach 130°C; (2) Extrude and compound the inner plastic film on the two surfaces of the strip-shaped metal foil through two horizontal rubber rollers; (3) After compounding, the heating zone is cured to make the surface temperature of the inner plastic film reach 65° C.; (4) extrude and compound the outer layer of plastic film to the two surfaces of the inner layer of plastic film through two horizontal rubber rollers.

Abstract

The invention discloses a double-layer plastic film composite tape. The tape comprises a strip metal foil, wherein an inner plastic film and an outer plastic film are adhered to the strip metal foil through two-step composition on the outer surface of the metal foil. The outer plastic film of the composite tape can be easily peeled from the inner plastic film, and the inner plastic film and the outer plastic film do not destroy each other. In the process of manufacturing a cable, longitudinal wrapping lap self-adhesion performance is high, and the composite tape has excellent effect of blocking damp invasion, so a cable core is protected. The double-layer plastic film composite tape has higher corrosion resistance because plastic layers are coated on two sides of a metal tube shielding tape, and an isolation layer with chemical corrosion resistance is arranged between the metal component layer and corrosive water and gas. The manufacturing method is simple, the process technology is mature and reliable, and the manufactured composite tape has a flat, smooth and uniform surface.

Description

technical field [0001] The invention belongs to the technical field of communication materials, and in particular relates to a double-layer plastic film composite tape used for making optical cables or cable shielding layers and a manufacturing method. Background technique [0002] In the current technical application, the outer layer of the plastic film composite tape is only compounded with a layer of plastic film of about 0.05mm. It is a one-time composite paste of the plastic film on the two surfaces of the metal foil and the tape through a high-temperature process. The compounded metal foil and plastic film with one side can form the effect of separating the double-layer plastic film by peeling off, and the bonding strength between the plastic film and the metal foil and tape cannot be fully guaranteed, resulting in poor corrosion resistance and long service life of the composite tape. short. Contents of the invention [0003] The purpose of the present invention is ...
