Abstract
The invention belongs to the field of cables and discloses ethylene acrylic glue for a composite metal strip. The ethylene acrylic glue for the composite metal strip is prepared by adding a paraffin wax emulsion, a water-based leveling agent and a water-based silica dioxide solution into ethylene acrylic resin, wherein counted by the total weight, the adding amount of the paraffin wax emulsion is 5-8%, the adding amount of the water-based leveling agent is 0.8-1% and the adding amount of the water-based silica dioxide solution is 5-8%. When the ethylene acrylic glue is used in production, a back-sticking phenomenon of the glue can be avoided and the surface of a glue layer is uniform and flat. When the ethylene acrylic glue is used for manufacturing composite metal strips (such as an aluminum foil shield), a 25-micron EAA (ethylene acrylic acid) film on the aluminum foil shield is replaced with a 4-micron glue layer while the mechanical properties and the shielding performance of the obtained aluminum foil shield are superior to those of the existing aluminum foil shield; and the obtained aluminum foil shield and the existing aluminum foil shield have equivalent adhesion strength while the production cost of the obtained aluminum foil shield is greatly reduced.
Description
Technical field
The invention belongs to field of cables, be specifically related to a kind of ethylene acrylic glue for composite metal belt.
Background technology
Existing cable, cable (such as CATV cable and MATV cable) especially for the signal conveying, for preventing cable inside or extraneous electromagnetic interference and rf attenuation, usually coat cable conductor with dielectric isolation layer first, and then clad metal screen layer, now widely used metallic shield layer material is ethylene acrylic acid co polymer Film laminated metal strip, such as aluminum foil shielded, between ethylene acrylic acid co polymer (EAA) film and metal tape base good cohesiveness is arranged, good heat sealability is simultaneously with macromolecular material PP as cable sheath, PE etc. also have good cohesiveness.Because the EAA resin has high cementability, to after-tack phenomenon very serious for glue when directly using EAA to be coated on metal strip, do not obtain practical to the present, therefore, existing this class composite metal belt of producing all adopts thermo-compression bonding method (dry method), being about in type EAA film is attached on the metal strip of preheating at the composite roll place, the shortcoming that adopts this thermo-compression bonding method is that the thickness of EAA film is determined by purchasing product, buying producer can't effectively adjust, when film thickness further reduces, the tensile strength of self also will reduce, thereby increases loss, and the EAA film thickness adopts 25 μ m usually during such as the production aluminum foil shielded.Therefore, be necessary to develop a kind of technology that can directly EAA be coated on the metal strip, in the situation that do not affect the metal compound belt performance, reduce the EAA consumption, to reduce production costs.
Summary of the invention
The objective of the invention is to solve existing EAA glue because after-tacking the shortcoming that causes directly to be coated on the metal strip, a kind of ethylene acrylic glue for composite metal belt is provided.
A kind of ethylene acrylic glue for composite metal belt, it is to obtain by add paraffin wax emulsions, water-based flow agent and water-based silicon dioxde solution in acetate acrylic resin, wherein, by gross weight, the addition of paraffin wax emulsions is 5%～8%, the addition of water-based flow agent is 0.8%～1%, the addition of water-based silicon dioxde solution is 5%～8%.
Further, also be added with dyestuff in the described glue.
Further, also be added with the froth breaking auxiliary agent in the described glue.
Further, adopt above-mentioned ethylene acrylic glue to apply the composite metal belt that obtains, the ethylene acrylic bondline thickness is 4 μ m on the composite metal belt that coating obtains.
Further, described composite metal belt is made of aluminium 9 μ m+polyester belts 15 μ m+aluminium 9 μ m+ ethylene acrylic glue-lines 4 μ m.
Beneficial effect: adopt ethylene acrylic glue of the present invention, when making composite metal belt (such as aluminum foil shielded), EAA on the aluminum foil shielded can be down to the glue-line of 4 μ m by the film of original 25 μ m, but the mechanical property of gained aluminum foil shielded of the present invention is better than existing aluminum foil shielded, both cohesive strengths are suitable, have the shielding properties more stable than existing aluminum foil shielded, production cost then greatly reduces.Aborning, do not have glue and after-tack phenomenon generation, gained glue-line surface uniform, open and flat.
