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
The invention belongs to communication material technology field, especially relate to a kind of double-layered plastic film composite tape and preparation method for making optical cable or cable shield.
Background technology
In existing technology is used, the skin of plastic sheeting composite band only is compounded with the plastic sheeting about one deck 0.05mm, it is with on disposable compound two surfaces that paste metal forming, band of plastic sheeting by high-temperature technology, can't make compound good metal forming, form effect by the double-plastic that cuts separation with the plastic sheeting of single face, can not guarantee the adhesion strength of plastic sheeting and metal forming, band fully, cause the corrosion resistance of composite band poor, service life is short.
Summary of the invention
The object of the invention is to the deficiency for existing plastic sheeting composite band existence, provide the adhesion strength of a kind of plastic sheeting and metal forming high, corrosion resistance is strong, a kind of double-layered plastic film composite tape of long service life.
Another object of the present invention is to provide a kind of preparation method of double-layered plastic film composite tape.
The technical scheme of product of the present invention is: a kind of double-layered plastic film composite tape, and it comprises belt metal foil, the outer surface composite plastic film in metal forming is characterized in that: described plastic foil comprises inner plastic film and outer layer plastic film.
Described inner plastic film and outer layer plastic film all adopt sealed polyethylene plastic, preferred EAA plastic sheeting.
Described inner plastic film and its thickness of outer layer plastic film are 0.025mm.
The technical scheme of the inventive method is: a kind of preparation method of double-layered plastic film composite tape, and it in turn includes the following steps:
(1) the preheating of belt metal foil through the compound front thermal treatment zone and the heat drum thermal treatment zone, make the metal foil surface temperature reach 100～150 ℃;
(2) the rubber roll extrusion cladding of inner plastic film by two levels pasted on two surfaces of belt metal foil;
(3) through thermal treatment zone slaking after compound, make the inner plastic film surface temperature reach 40～100 ℃;
(4) outer layer plastic film is pasted on two surfaces of inner plastic film by two horizontal rubber roll extrusion claddings.
That step (1) makes the preheating of belt metal foil through the compound front thermal treatment zone and the heat drum thermal treatment zone metal foil surface temperature reach 110～130 ℃ as the preferred scheme of the present invention.
As the present invention further preferred scheme be that step (3) makes the inner plastic film surface temperature reach 55～65 ℃ through thermal treatment zone slaking after compound.
Advantage of the present invention is: this double-layered plastic film composite tape is that the appearance at belt metal foil is compounded with the two layers of plastic film, cause on can be the securely compound surface that pastes metal forming of inner plastic film, and outer layer plastic film can be easy to from the inner plastic film peel away, and does not mutually destroy.The plastic sheeting composite band of this structure, vertical bag overlap joint self-adhesion is good in the process of making cable, and composite band has good barrier effect to the intrusion of moisture, thereby has protected cable core.It also has high anti-corrosive properties, because the two-sided coated plastic layer in metal tube mask tape, just is provided with anti-chemical corrosive separation layer between metal assembly layer and corrosive water, gas.In addition, good cementability is arranged between composite band and plastic sheath, screen layer and oversheath form an integral body, so that the intensity of metal assembly combines with extensibility and the fatigue durability of plastic sheath, have improved the mechanical performance of cable.
The preparation method of double-layered plastic film composite tape of the present invention is simple, the technology mature and reliable, the composite band surface that produces should be smooth, smooth, even, free from admixture, non-wrinkle, without piebald and without other mechanical damage defectives, the composite band of cutting should be smooth, and end face should be without crimping, breach, burr and other mechanical damages.When pulling out, the edge is without obvious waveform.
