Abstract
The invention relates to an outer layer hot-melt aluminum foil for a three-screened coaxial cable. The outer layer hot-melt aluminum foil comprises a double-face aluminum foil body, the double-face aluminum foil body comprises a first aluminum foil layer, a plastic reinforcement layer and a second aluminum foil layer, a hot-melt layer is compounded on the outer surface of the second aluminum foil layer, and the first aluminum foil layer, the plastic reinforcement layer, the second aluminum foil layer and the hot-melt layer are sequentially arranged. According to the outer layer hot-melt aluminum foil, the hot-melt layer which is in direct contact with an outer jacket is compounded on the outer side of the second aluminum foil layer, when the outer jacket is manufactured, the hot-melt layer is melted to be well bonded with the outer jacket after being heated, relative sliding between the outer jacket and a special outer layer aluminum foil body is avoided, and the stability of the production structure and the stability of the electric performance are improved. The hot-melt layer which is in direct contact with the outer jacket is compounded on the outer side of the second aluminum foil layer, when the outer jacket is manufactured, the hot-melt layer becomes a main absorption point of heat, and phenomena such as strip breakage caused by excessive heating of a plastic layer on the interior are avoided.
Description
(1) technical field
The present invention relates to the electric wire and cable material manufacture field, specifically, the present invention is a kind of three screened coaxial cables with outer heat molten type aluminium foil.
(2) background technology
In general, the basic composite construction of physical blowing cable TV three screened coaxial cable outer conductor is: aluminium foil vertical bag (internal layer)+aluminum-magnesium alloy wire braiding vertical bag of (second layer)+aluminium foil (skin), the internal layer aluminium foil adopts double-sided self-adhesive aluminum foil, and outer foil adopts double-sided aluminum foil.This structure is the most general application form at present.Technical literature both domestic and external shows, has the three Design and manufacture aspects that shield cable tv coaxs now and has the following disadvantages:
1, outer double-sided aluminum foil is when the vertical bag of sheath production, and aluminium foil easily produces " initial line " phenomenon, thereby it is defective to cause locating the thinnest point of sheath at " initial line ", causes the quality waste larger;
2, after the cable finished product, between technological requirement sheath and outer foil, can not having slides exists, customer requirement sheath and outer foil will be combined closely simultaneously, preferably can realize to a certain degree bonding, this brings very large difficulty for the Design and manufacture of three screened coaxial cables, and this point is also the general character difficult problem that three shielding cable tv coax industries are faced;
3, common outer double-sided aluminum foil is when the sheath operation is produced, and while due to sheath, extruding, temperature is higher, brings a large amount of heats, and aluminium foil is subjected to thermal softening easily to produce broken belt, affects product quality and production efficiency, also produces a large amount of wastes.
(3) summary of the invention
The present invention has overcome above-mentioned shortcoming, a kind of three screened coaxial cables have been proposed with outer heat molten type aluminium foil, the outer double-sided aluminum foil outside (i.e. a side of close sheath) common in tradition increases by a hot melt layer, the aluminium foil of making and the adhesive property of sheath are good, stable, and physical property and processing performance meet the actual production requirement simultaneously.
For this reason, the present invention takes following technical scheme:
A kind of three screened coaxial cables are with outer heat molten type aluminium foil, include double-sided aluminum foil, described double-sided aluminum foil includes the first aluminium foil layer, plastics reinforced layer and the second aluminium foil layer, described the second aluminium foil layer outer surface is compounded with hot melt layer, and described the first aluminium foil layer, plastics reinforced layer, the second aluminium foil layer and hot melt layer are arranged successively.
Described the first aluminium foil layer and the second aluminium foil layer are the alloy aluminium foil, and thickness is 0.009-0.012mm.
Described plastics reinforced layer is the PET polyester film, and thickness is 0.015-0.020mm.
Described hot melt layer thickness is 0.005-0.015mm.
The formula of described hot melt layer is: base resin glue, antioxidant, thickener, curing agent, solvent, its part by weight are 100:(0.5-1.5): (3-5): (0.5-1.5): (250-350).
Before production, first according to above-mentioned formula, prepare glue, then glue is coated in equably to the outer surface of the second aluminium foil on compounding machine, realize solidifying of glue through the baking oven of 70-90 ℃, form good bonding with aluminium foil.
The inventor recommends to realize from following aspect performance judgement of the present invention:
(1) in the second aluminium foil layer outside, be compounded with the hot melt layer that one deck directly contacts with oversheath, when sheath was produced, this hot melt layer melted by heating and sheath were realized good bonding, avoid the relative sliding between oversheath and aluminum foil special for outer layer, improved stablizing of product structure and stablizing of electric property;
(2) in the second aluminium foil layer outside, be compounded with the hot melt layer that one deck directly contacts with oversheath, when sheath was produced, this hot melt layer became the main absorption point of heat, had avoided inner plastic layer to be heated excessively, caused the phenomenons such as broken belt;
While (3) due to sheath, producing, this hot melt layer melted by heating and sheath are realized good bondingly, have also contained to a certain extent the generation of the bad quality such as aluminium foil fold, " initial line ".
(4) accompanying drawing explanation
Fig. 1 is the structural representations of a kind of three screened coaxial cables of the present invention with outer heat molten type aluminium foil.
(5) embodiment
A kind of three screened coaxial cables of the present invention require as follows with the concrete preparation of outer heat molten type aluminium foil:
(1) composite glue is joined glue: the glue prepared must carry out good sealing, to prevent the glue spontaneous curing; Encapsulating method: be wound around with adhesive tape after building capping, guarantee good seal.
(2) hot melt glue is joined glue: the formula of described hot melt layer is: base resin glue, antioxidant, thickener, curing agent, solvent, its part by weight are 100:(0.5-1.5): (3-5): (0.5-1.5): (250-350).The glue prepared must carry out good sealing, to prevent the glue spontaneous curing; Encapsulating method: be wound around with adhesive tape after building capping, guarantee good seal.
(3) first is compound: ground floor alloy aluminium foil layer and a PET laminated polyester film are compound first, compound tight, and middle pore-free is wrinkle resistant, etc.; Compound tense is used composite glue.
(4) second is compound: a second layer alloy aluminium foil layer and compound good PET polyester film face is compound first, require compound closely, middle pore-free, wrinkle resistant, etc.; Compound tense is used composite glue.
