A preparation method of the abrasion-resistant and corrosion-resistant optical cable comprises the following steps:
the method comprises the following steps: firstly, selecting an optical fiber with excellent transmission characteristic and qualified tension, coating ultraviolet curing ink on the surface of the optical fiber through a coloring mold by using an optical fiber coloring machine, and then fixing the optical fiber on the surface of the optical fiber after curing by using an ultraviolet curing furnace to form the optical fiber easy for color separation, thereby coloring the optical fiber, wherein the standard after coloring the optical fiber meets the following requirements, the color of the colored optical fiber is not transferred and faded, the optical fiber is arranged in a neat and flat manner, the optical fiber is not subjected to disorder and line pressing, the attenuation index of the optical fiber meets the requirements, the OTDR test curve has no step phenomenon, and the coloring work of the optical fiber is completed;
step two: selecting a proper high polymer material, adopting an extrusion molding method, sleeving loose tubes on optical fibers by a secondary plastic sleeving machine under a reasonable process condition, filling cable core fillers between the loose tubes and the optical fibers, then performing yarn binding work on six loose tubes by operating an optical cable cabling machine, and adding a central reinforcement between the six loose tubes for reinforcing and supporting, so that the flexibility and the flexibility of the optical cable are increased by a yarn binding layer, the tensile strength of the optical cable is improved, the temperature characteristic of the optical cable is improved, the optical cable is manufactured by combining the six loose tubes, and the tube fillers are filled in the yarn binding layer;
step three: selecting a polyethylene material, fixedly sleeving a polyethylene inner sheath outside the yarn binding layer through an optical cable sheath plastic extruding machine, then winding and fixing a steel-plastic composite belt outside the polyethylene inner sheath, fixedly adhering the steel-plastic composite belt and the outer wall of the polyethylene inner sheath through non-corrosive strong glue, fixedly sleeving a thin steel wire armor layer on the outer wall of the steel-plastic composite belt through the optical cable sheath plastic extruding machine again, and after the thin steel wire armor layer is sleeved, fixedly sleeving a polyethylene outer sheath on the outer wall of the thin steel wire armor layer through the optical cable sheath plastic extruding machine;
step four: and then painting, firstly painting two epoxy zinc-rich primers on the outer wall of the polyethylene outer sheath, and after the epoxy zinc-rich primers are required to be dried up, the dry film thickness of the epoxy zinc-rich primer coating is 2 x 50 mu m, then painting two epoxy micaceous iron intermediate coatings on the outer wall of the epoxy zinc-rich primer coating, and after the epoxy micaceous iron intermediate coatings are required to be dried up, the dry film thickness of the epoxy micaceous iron intermediate coating is 2 x 50 mu m, finally painting two fluorocarbon finish coatings on the outer wall of the epoxy micaceous iron intermediate coating, and after the fluorocarbon finish coatings are required to be dried up, the dry film thickness of the fluorocarbon finish coatings is 2 x 50 mu m, and then after the fluorocarbon finish coatings are dried up, fixedly sleeving the nylon outer sheath on the outer wall of the polyethylene outer sheath by operating an optical cable sheath extruding machine, thereby completing the manufacture.
Compared with the prior art, the invention has the beneficial effects that:
1. according to the invention, the thin steel wire armor layer, the polyethylene outer sheath, the polyethylene inner sheath and the steel-plastic composite belt are arranged, so that the optical fiber in the optical cable can be subjected to primary wear-resistant protection through the polyethylene outer sheath and the thin steel wire armor layer, and then the optical cable is subjected to secondary wear-resistant protection through the steel-plastic composite belt and the polyethylene inner sheath, so that the optical cable can be subjected to multiple protection, the protective layer of the outer ring of the optical cable is more wear-resistant, the outer ring of the optical cable is prevented from being damaged easily due to wear, and the optical fiber in the optical cable is damaged due to external influence The epoxy micaceous iron intermediate coat and the fluorocarbon finish coat are combined and smeared, so that the corrosion resistance of the optical cable is better, the optical fiber inside the optical cable is prevented from being damaged due to corrosion caused by external reasons when the optical cable is used, the transmission work is influenced, and the fluorocarbon finish coat can be prevented from being worn by arranging the nylon outer sheath, so that the corrosion resistance effect is influenced.
2. By arranging the installation mechanism, because the optical cable is generally fixedly installed through the installation sleeve and the expansion screw when being installed, when the optical cable needs to be replaced or maintained, the expansion screw needs to be removed when the optical cable needs to be removed, so that the optical cable needs to be removed too inconveniently, the fixed plate is fixedly connected with the installation surface through the expansion screw, the optical cable is inserted in the fixing grooves in the first fixing seat and the second fixing seat, the optical cable is fixed through the first fixing seat and the second fixing seat, when the optical cable needs to be removed, the limiting disc only needs to be pulled to one side, the positioning rod is separated from the first positioning groove, the control rod is then moved downwards and can be inserted in the second positioning groove, the control rod moves downwards, and the control rod drives the control block to move to the inside of the storage groove, consequently there is not the support of control block, control spring can rebound and remove the movable plate to locating piece department, thereby the movable plate can promote the locating piece, make the locating piece move to the inside of sliding tray, and one side of later movable plate is laminated with one side of plug socket, the locating piece can remove the inside to the sliding tray completely, and a side end face of locating piece can be in same vertical plane with a side end face of plug socket, thereby the locating piece can't carry on spacingly to the plug socket, the plug socket can directly separate with the plug socket, consequently the staff can directly shift out the second positioning seat, later shift out the optical cable, thereby need not to demolish the inflation screw, when making demolish the optical cable, only need the spacing dish to remove, later just can accomplish the demolishment with the control lever is shifted down, make the convenience of demolising more.
3. When the optical cable needs to be installed again, after the optical cable is placed in the fixed groove, the limiting disc only needs to be pulled, then the control rod is moved, the control rod pushes the control block to move upwards in the movable groove, then the upper end face of the control block moves to be attached to the upper inner wall of the movable groove, one end of the positioning rod is inserted into the first positioning groove to be limited, the control block can push the limiting blocks on the two sides to the two sides, so that one end of the positioning block moves to one side of the inserting seat, the positioning block can push the movable plate to compress the control spring, one end of the positioning block can be located above the first fixing block, the inserting seat cannot be separated from the inserting groove through the limiting of the positioning block, the first fixing seat cannot be separated from the second fixing seat, and the optical cable body can be extruded and fixed through the rubber pad by the fixed groove in the first fixing seat and the second fixing seat, the installation is completed, so that the installation is more convenient, the installation can be completed only by operating the limiting disc and the control rod, and the expansion screw does not need to be installed again.
