Description
Technical field
The present invention relates to optical cable manufacturing technology field, relate in particular to a kind of manufacture method of colored optical fiber.
Background technology
Optical cable is the main delivery means of the various Information Networks of current information society, and wherein optical fiber is the core component of optical cable.Be the optical fiber in identification optical cable or the fibre ribbon, so as in the installation of optical cable, continue, can correctly find required optical fiber rapidly when safeguarding, at present in the industry institute generally the method for employing be to label with color, distinguish different optical fiber with distinct colors.Make the method for different colours on the fibre ribbon mainly contain painted at present and two kinds of lock looks, the optical fiber of being produced is called colored optical fiber and lock coloured light fibre.
Usually the coat of optical fiber has two-layer, adopt two kinds of different coating respectively: the first layer is a kind of soft buffer coating, modulus is in 10Mpa, and its function is protection optical fiber and the isolated external stress that can cause little loss on transmission consumption, improve optical fiber tensile strength, make the minimizing microbending loss; The second layer is a kind of tough and tensile coating, and modulus is at hundreds of Mpa, and its function is to improve optical fiber anti-pressure ability and wear-resistant ability, makes it have certain mechanical strength for the enough protections of optical fiber.
The chemical ingredients that true qualities optical fiber applies in the coating is mainly acrylic resin chain prepolymer and Acrylic Acid Monomer and auxiliary agent and light trigger.Wherein acrylic resin prepolymer and monomer are the backbone structure of prescription in the composition, and they have determined the basic physical property of coating, and physical and mechanical propertiess such as the hardness of coating, snappiness are had tangible influence.Light trigger can produce free radical under UV light, and the two keys in these free radical bump coating make acrylic resin prepolymer and monomer polymerization reaction take place, forms the solid polymer of intersection chain structure then, and this is the process of paint solidification just.The crosslinking degree that final fiber strength depends primarily on the intersection chain is a degree of cure.
Painted is the method that makes color on the fibre ribbon that present most of optical fiber cable manufacturer uses, its optical fiber structure such as Fig. 4, a covering is contained at its center, and the covering outer circumferential side is provided with the first true qualities coating and the second true qualities coating, is provided with the colored ink layer at the outer circumferential side of the second true qualities coating.Paintedly normally finish true qualities optical fiber surface after overtension screening in wire drawing, be coated with once more and be covered with the coloured coloring printing ink of very thin one deck, after UV curing, the optical fiber all surface is just covered by thin and firm polymer layer, and pigmented layer thickness is generally about 5 μ m.Because of pigmented layer is thinner, be easy to solidify, so the pigment ratio is relatively large in the coloring printing ink, colored optical fiber is bright-colored.Because of painted be with the optical fiber unwrapping wire of having received on the dish once more, apply coloring printing ink, UV is received on the wire spool after solidifying again, the diameter of true qualities fibre is wayward, cause the optical fiber external diameter wider distribution after painted, in addition, the clean-up performance of painted mould, whether the center of flowline centering, the control of retractable cable tensile, the control of gas in the color solidification, the cleaning of coloring printing ink and degree of uniformity, the working order of UV lamp, even the clean situation of true qualities optical fiber to be colored and surrounding working environment, all be to produce dysgenic hidden danger to the optical fiber quality in the coloring process, in case any one details goes wrong, the capital causes optical fiber the surface decolouring to occur, in the colored optical fiber coating bubble is arranged, the pigmented layer concentricity is bad, and serious meeting causes optical fiber attenuation to increase or the PMD deterioration.After the colored optical fiber that is up to the standards dispatches from the factory, also often have to overlap to mould and find in the production that pigmented layer fades, even the fine accident that comes off at optical cable construction field optical fibers pigmented layer, breaks also happens occasionally.In sum, although the colored optical fiber color and luster is lucid and lively, paintedly itself also bring " potential threat " for optical fiber.
It is the lock look that another kind makes on the fibre ribbon method of color, i.e. 12 kinds of color paints formulating according to international standard, color directly is added to the second time of optical fiber in the coat, its optical fiber structure such as Fig. 5, a covering is contained at its center, and the covering outer circumferential side is provided with the first true qualities coating, is provided with second coloured coating at the outer circumferential side of the first true qualities coating, from wire-drawer-tower, directly pull out coloured optical fiber, do not need again the painted cover that is directly used in to mould production afterwards.Produce the product that directly obtains because of lock coloured light is fine for wire drawing, so compare with colored optical fiber, outside diameter control is better, and incomparable homogeneity of colored optical fiber and homogeneity are arranged, and also can avoid the improper detrimentally affect that optical fiber is caused of coloring process in addition.Because of the thickness of second coloured coating is about 25 μ m, thick more a lot of than the pigmented layer (5 μ m) of colored optical fiber, so can avoid the phenomenon of decolouring, fade, fading fully.
The fine used coating of lock coloured light, the first layer is similar to the true qualities optical fiber coatings, the second layer is a colo(u)r coating, promptly in coating, add suitable pigment, the effect of pigment is to pigment dyeing, makes optical fiber just be with color after the second layer applies, but simultaneously also can the shield portions UV-light, if select incorrectly, then can cause negative influence to the curing of coating.Because of locking the fine second layer coating thickness of coloured light almost at 25 μ m, thickness than 5 μ m of colored optical fiber pigmented layer is howed a lot, so, the granularity of the pigment in the colo(u)r coating of the fine usefulness of requirement lock coloured light, dispersity and transparence, should make and be coated with color on the strip, can not absorb and cover too much UV-light again, cause locking the coloring printing ink of the relative colored optical fiber of colo(u)r coating of the fine usefulness of coloured light, wherein the pigment ratio is less, because of the shading reason can't be added some highlighted material, color is bright inadequately mostly, and this is to the optical cable construction of frequent need under the darker environment of light, especially piping installation can't but be kind of a shortcoming.In addition; fine because the reason that second layer color layer is thicker of lock coloured light to the second layer solidifying requirements of optical fiber than higher; to the requirement of production technique and equipment also than higher; power as curing oven and UV lamp; oxygen concn control in the curing oven silica tube; real-time monitoring of the intensity of illumination of UV lamp or the like; in addition; the variation of drawing speed; one deck applies the fluctuation of external diameter; even the degree of stability of service voltage or the like; the capital has influence on the curing of the second color layer coating; in case two layers solidify not enough; will occurring of the interface of two layers and one deck in conjunction with insecure phenomenon; then take place one; separate two bed interfaces; reduction is to the provide protection of optical fiber; reduce mechanical fiber optic intensity, thereby and under the bigger situation of temperature variation, shrink asynchronous the unusual of decay index that cause, serious meeting causes disconnected fine.The harshness of this equipment and technology controlling and process requires to be mainly reflected in and to solidify related aspect, has also limited to the popularization of the fine technology of lock coloured light.
Summary of the invention
