The utility model has the advantages of tensile strength is strong, cladding effect and electromagnetic shield are effectual.
Description
Technical Field
The utility model relates to an aluminium-plastic composite belt field, more specifically say, it relates to a hot melt aluminium foil.
Background
The traditional hot-melt aluminum foil belt is formed by compounding a PET (polyethylene terephthalate) base band, polyurethane glue and an aluminum foil, and has excellent shielding effect and mechanical and physical properties. The PET as a base material has good tensile strength, elastic modulus, acid and alkali resistance and weather resistance, but the rigidity of the PET material is high, the wrapping is not tight due to stress release and other conditions after the cable is wrapped, and in order to ensure the wrapping effect, the tension of the hot-melt aluminum foil needs to be increased, but the hot-melt aluminum foil is easy to deform after being subjected to high tension, so that the shielding effect is influenced, and even the quality problems such as belt breakage and the like occur.
Therefore, a new solution is needed to solve this problem.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model aims to provide a hot melt aluminium foil has tensile strength can be strong, cladding effect and the effectual advantage of electromagnetic shield.
The above technical purpose of the present invention can be achieved by the following technical solutions: the utility model provides a hot melt aluminum foil, includes BOPP rete, polyurethane glue layer, aluminium foil layer and vinyl chloride-vinyl acetate resin hot melt adhesive layer, BOPP rete and aluminium foil layer pass through the polyurethane glue layer and connect, vinyl chloride-vinyl acetate resin hot melt adhesive layer sets up the one side that deviates from the polyurethane glue layer on the aluminium foil layer.
In one embodiment, the thickness of the vinyl chloride-vinyl acetate hot melt adhesive layer is 2um to 5um.
In one embodiment, the aluminum foil layer has a thickness of 9um.
In one embodiment, the BOPP film layer has a thickness of 20um.
In one embodiment, the polyurethane glue layer has a thickness of 3.0um to 3.2um.
To sum up, the utility model discloses following beneficial effect has: 1. through the arrangement of the BOPP film layer, the tensile strength of the BOPP film layer is more than 150% of that of a common PET film layer, so that the problems of low strength, easy deformation and the like of a common hot-melt aluminum foil are solved, the hot-melt aluminum foil is more tightly coated with a cable core of a cable, and the structural stability and the electrical performance of the cable core are improved; 2. the density of the BOPP film layer is only about 65% of that of the PET film layer, and the low density means low price, so that the material cost can be effectively reduced, and the comprehensive cost performance of the product is improved; 3. through the arrangement of the vinyl chloride-vinyl acetate hot melt adhesive layer, the vinyl chloride-vinyl acetate hot melt adhesive has the characteristics of high toughness, corrosion resistance and strong viscosity, and when the cable is used, the vinyl chloride-vinyl acetate hot melt adhesive layer can be bonded with the sheath of the cable core after being heated, so that the structural strength of the cable can be further enhanced, and the cable can be cut and stripped more conveniently and quickly in the subsequent process; 4. the aluminum foil is used as the base layer, the aluminum foil is cheaper than a copper foil and is more suitable for being used in cables with low quality requirements, and the aluminum foil can form a compact oxide film to protect the aluminum foil after contacting with air, so that the reaction between the aluminum foil and a vinyl chloride-vinyl acetate hot-melt adhesive layer can be avoided, and the stability is better.
