Description
Technical field
The present invention relates to a kind of optical cable non-metallic fibers and strengthen core, a kind of virtue scribbling flexible coat
Synthetic fibre strengthens core and preparation method thereof.
Background technology
Along with the progress of science and technology, optical cable has entered into all trades and professions.Optical cable strengthens the important unit that core is communications optical cable
Part, traditional strengthening core is based on phosphating steel wire.Under humid air, hardware corrosion and biochemical corrosion can produce liberation of hydrogen,
Affect the transfer function of signal.In addition, processing cost when steel wire and optical fiber are prepared as optical cable is higher, and mechanics, corrosion resistant
Erosion performance is all not sufficiently stable.In recent years, non-metallic optical fiber cables center reinforcement starts progressively to apply and popularize, with conventional phosphatizing steel wire
Strengthening core is compared, and fibre reinforced composites optical cable strengthens the feature that core has light weight, corrosion-resistant, hot strength is high.
At present, non-metallic optical fiber cables center reinforcement mainly uses the composite bar that glass fibre or aramid fiber strengthen,
Wherein aramid fiber reinforced composite optical cable enhancing core is because of its lower density, more preferable break resistance, becomes phosphating steel wire light
Cable strengthens the good substitute products of core.But, optical cable prepared by aramid fiber reinforced composite strengthen core still suffer from toughness poor,
The problem such as bright and clean, bending resistance radius is bigger is owed on surface.The method solving above-mentioned technical problem at present mainly uses injection extrusion method
Wrap up layer of polyethylene sheath on aramid fiber reinforced composite bar surface, the aramid fiber that this method can obtain any surface finish is multiple
Condensation material bar, but the injection increased is extruded workshop section and is added significantly to the process complexity of composite material optical cable enhancing core, and this mistake
Journey needs High Temperature High Pressure, and power consumption is big, and strengthens core toughness and still promote limited.
In order to overcome existing aramid fiber composite material to strengthen, core toughness is poor, bright and clean deficiency is owed on surface, and the present invention provides a kind of
Aramid fiber reinforced composite optical cable containing flexible coat strengthens the preparation method of core, the method use twice impregnation, four sections solid
Metallization processes, once completes the preparation of aramid fiber reinforced composite core and the coating of surface flexible layer, it is not necessary to High Temperature High Pressure, technique mistake
Journey green safety, prepared enhancing core is the most lightweight, and surface smoothness is good, owing to the introducing enhancing core of flexible coat is tough
Property improve, bending radius decline, whole process reduce further strengthen core production cost.
Summary of the invention
It is an object of the invention to, it is provided that a kind of aramid fiber reinforced composite optical cable containing flexible coat strengthen core and
Preparation method.
The technical solution of the present invention is as follows: a kind of aramid fiber reinforced composite optical cable containing flexible coat strengthens
Core, the described aramid fiber containing flexible coat strengthens core and is made up of aramid fiber bar core, matrix resin layers and flexible coat.
Described aramid fiber bar core is that aramid fiber forms with matrix resin crosslinking curing.
Described matrix resin layers is that one or more in vinylite, epoxy resin or bimaleimide resin are solid
Change forms.
Described flexible coat is polyvinyl acetate.
The described aramid fiber reinforced composite optical cable containing flexible coat strengthens a diameter of 0.18mm 6mm of core；
Described flexible coat thickness is 0.05mm 2mm；
Described a kind of aramid fiber reinforced composite optical cable containing flexible coat strengthens preparation method (the non-plastic work of core
Skill), use the pultrusion method containing twice impregnation, four sections of curing process steps to prepare, comprise the steps:
1) impregnation for the first time: aramid fiber yarn is fully infiltrated with matrix resin in the first glue groove；
2) first paragraph solidification: matrix resin aramid fiber yarn will be soaked with and add hot extrusion solidification through mould duct；
3) second segment solidification: described step 2) product again through drying tunnel heating again solidify；
4) impregnation for the second time: described step 3) obtains product and infiltrates with polyvinyl acetate emulsion in the second glue groove；
5) the 3rd section of solidification: described step 4) obtains product and is heating and curing through the plastic squeeze of mould duct；
6) the 4th section of solidification: described step 5) obtains product and completes the solidification of flexible coat again through hot blast drying tunnel.
7), after the cooling of described step 6) product air, i.e. can get aramid fiber reinforced composite optical cable and strengthen core finished product receipts
Volume.
First paragraph solidification heating-up temperature 135 ± 10 DEG C, second segment solidifies: high through drying tunnel or post-heater (5) heating-up temperature
In first paragraph temperature 30-50 DEG C；When matrix resin layers selects vinylite, epoxy resin or bimaleimide resin difference
Temperature slightly difference；3rd section of solidification: through Glue Squeezing device (7) after impregnation, through the heating-up temperature 95 ± 10 DEG C of mould (8), the
Post-heater (9) heating-up temperature 110 ± 10 DEG C of four sections of i.e. the 3rd section of solidifications of solidification.
The method have the benefit that the preparation of aramid fiber reinforced composite core and the coating of surface flexible layer once complete, it is not necessary to
High Temperature High Pressure, technical process green safety, prepared enhancing core is lightweight, and surface smoothness is good, due to flexible coat
Introducing and use multistage solidification to make the toughness of enhancing core improve, testing through every physicochemical property, bending strength improves up to 20%,
Bending resistance radius declines up to 30%.Compared to existing plastic technique, the aramid fiber reinforced composite containing flexible coat of the present invention
Optical cable strengthens core its preparation method, and is continuous processing method, and minimizing 70% of consuming energy, product cost is remarkably decreased.
