In the incineration process, no harmful substances such as dioxin are generated, and in the landfill process, it relates to an optical fiber code that releases little harmful substances such as heavy metal compounds. Background art
- non-halogen flame-retardant coating materials in which polyolefin resin components are filled with a high concentration of metal hydrate instead of coating materials containing halogen such as polyvinyl chloride
- Japanese Patent Application Laid-Open No. Hei 9-337770 discloses an example of a material used as a coating material for optical fiber cores and optical cords.
- this conventional example was characterized only by the non-halogen flame retardancy of the conventional optical fiber cord, and no investigation was carried out including reduction in diameter.
- the modulus of elasticity is required to mix the flame retardant with high dispersibility and high concentration as the base resin of the coating material. Therefore, it was difficult to obtain the mechanical properties such as bending stiffness required for the optical fiber code.
- the outer diameter of the optical fiber cord is 1.2 mm or less, it is necessary for the optical fiber cord when a single layer of the composition highly filled with metal hydroxide is used as the optical fiber cord coating. There was a problem in that a predetermined bending stiffness could not be obtained, or that the bending habit remained easily after being held at a constant bending diameter for a long time and released.
- the optical fiber code is used for jumping (switching the optical wiring). It is necessary to remove any optical fiber cord end from the bundle of optical fiber cords wired with high density, and to bend more than a certain value to avoid buckling of the cord during the work. Rigidity is required.
- the present invention has been made to solve the above-mentioned problems, and an object of the present invention is to reduce the diameter of an optical fiber cord to 1.2 mm or less so as to achieve excellent flame retardancy, mechanical properties, and handling properties. O to provide optical fiber code
- FIG. 1 is a sectional view showing an example of an optical fiber cord.
- FIG. 2 is an explanatory diagram showing a method for evaluating the bending stiffness of an optical fiber cord.
- FIG. 3 is an explanatory diagram showing a method of a 90-degree bending test of an optical fiber cord with a connector. Disclosure of the invention
- the coating layer is a resin component containing at least one selected from the group consisting of a polyamide-based thermoplastic resin, a polyamide-elastomer-based thermoplastic resin, and a polyester-elastomer-based thermoplastic resin.
- the coating layer contains at least one or more selected from the group consisting of a polyamide-based thermoplastic resin, a polyamide-elastomer-based thermoplastic resin, and a polyester-elastomer-based thermoplastic resin.
- the composition is characterized in that the composition is obtained by mixing 180 to 60 parts by mass of a flame retardant composed of ammonium polyphosphate and a nitrogen-containing compound with respect to 100 parts by mass of the resin component. ).
- the optical fiber code having excellent flame retardancy, mechanical properties, transmission properties, and hand-ring properties.
- BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the optical fiber code according to the present invention will be described with reference to the drawings.
- FIG. 1 is a cross-sectional view of an optical fiber cord according to the present invention, in which 1 indicates an optical fiber cord, 2 is an optical fiber core, 3 is a tensile strength fiber layer, and 4 is a coating layer as a jacket. It is.
- the optical fiber used in the present invention refers to an optical fiber itself or an optical fiber obtained by applying a surface treatment such as resin coating thereon.
- the outer diameter of the resin-coated optical fiber core used in the present invention is preferably 0.25 mn! ⁇ 0.70mm, more preferably 0.4mn! ⁇ 0.6 mm. If the outside diameter is too small, the transmission loss increases due to bending of the optical code, and the lateral pressure characteristics decrease significantly.If the outside diameter is too large, it becomes difficult to achieve a loose structure with the outside diameter of the optical fiber of 1.2 mm or less. If the loose structure is not maintained, there is a risk that the core wire will buckle when the connector is connected.
- the loose structure means that the core wire in the optical fiber does not adhere to the tensile strength fiber or the outer jacket except for surface friction, and the optical fiber core does not buckle when the connector is connected. Is pushed into the inside of the card and stored for an extra length. In this case, if the amount of tensile strength fiber is reduced to maintain the loose structure, the required tensile properties cannot be satisfied.
- the tensile strength fiber As the tensile strength fiber, aramid fiber (trade name: Kevlar, Twaron, etc.) or PBO (poraf dienbenzo bisoxazole) fiber (trade name: ZYL0N) is used. It is preferably used. Tensile properties required for optical fiber cords and less than 1.2 mm ⁇ ⁇ In order to achieve the outer diameter of the optical fiber cord, the tensile modulus of the tensile strength fiber is preferably in the range of 70,000 to 120, OOOMPa. It is preferable that the total amount in a state where a plurality of fiber bundles are stretched is 100 to 220 mg / m (1000 to 220 decitex). Among these tensile strength fibers, PBO fiber has more than twice the elastic modulus of the aramid fiber, so the degree of freedom in designing the optical fiber code structure can be expanded.
- the tensile strength fiber layer is disposed on the outer periphery of the optical fiber core as shown in FIG.
- This tensile fiber layer is located between the central optical fiber core and the sheath resin layer, and does not come into contact with the optical fiber core or the sheath resin layer except for surface friction, and is vertically attached around the optical fiber core. Or are twisted.
- the area occupancy of the tensile fiber layer in the cross section of the optical fiber cord is not particularly limited, but is preferably 10 to 70%, and more preferably 30 to 50%.
- the thermoplastic resin constituting the outer periphery of the optical fiber core and the tensile strength fiber can be composed of one or more layers, but the outer diameter is 1.2 mm or less.
- the thickness of the coating layer as the jacket is 0.10 to 0.30 mm, and the bending elastic modulus of the base resin component of the coating material is 500 MP in view of the bending rigidity of the cord. It is preferable to have a to 1,30 OMPa. If the thickness of the coating layer is too small, the optical fiber cord tends to be flattened, and even if a coating material having a bending elastic modulus of about 1,30 OMPa is used, the bending required for the optical fiber code can be achieved.
- the non-halogen flame-retardant resin means that the resin composition is included, and here, "flame retardant" passes the flame retardancy in the horizontal burning test of JISC305 as described later.
- the coating layer made of a non-halogen flame-retardant resin may have a single-layer structure or a multilayer structure.
- At least the outermost layer is a polyamide thermoplastic resin, a polyamide elastomer thermoplastic resin or a polyester elastomer thermoplastic resin.
- a resin containing at least one of the thermoplastic resins based on 100 parts by mass of the base thermoplastic resin, preferably 18 to 60 parts by mass of an ammonium polyphosphate flame retardant It is blended, more preferably 25 to 50 parts by mass, and particularly preferably 25 to 40 parts by mass. If the amount of ammonium phosphate-based flame retardant is too small, the flame retardant properties of the optical fiber cord cannot be obtained, and if it is too large, the habit of bending the optical fiber cord for a long time tends to remain. The subsequent wiring work will be hindered. In addition, the mechanical properties of the coating material are significantly reduced. S.
- ammonium phosphate flame retardants include: Trade name “Hostaflam” (Clariant), “TERRA JU” (Chitz), “Sumisafe PM” (Sumitomo) Chemical Co., Ltd.).
- ammonium phosphate itself is soluble in water, but by using a powder coated with a surface coating, this water resistance problem can be overcome.
- TERRAJU is an example of such a surface-treated ammonium phosphate.
- melamine cyanurate When, for example, melamine cyanurate is used in combination with phosphorus-based ammonium phosphate as a nitrogen-based flame retardant, the flame-retardant properties are significantly improved. Therefore, it is possible to reduce the amount of the phosphorus-based flame retardant. It is preferable to use ammonium phosphate and a nitrogen-containing compound as flame retardants as a mixture.
- the melamine cyanate include “MC” manufactured by Nissan Chemical Industries, Ltd.
- phosphorus-based flame retardants have the effect of reacting with oxygen during combustion to form a film on the resin surface and block the supply of oxygen to the resin side. It is said that it has the effect of decomposing during combustion to generate nitrogen gas and create an inert atmosphere. In the present invention, it is considered that both act synergistically to significantly improve the flame retardancy.
- the total amount of ammonium phosphate and the flame retardant of the nitrogen-containing compound is 18 to 60 parts by mass, preferably 25 to 50 parts by mass, based on 100 parts by mass of the base resin. It is preferably 25 to 40 parts by mass. If the amount is too small, the composition does not pass the flame retardancy, and if it is too large, the bending tendency of the optical fiber cord tends to remain. ⁇ When a mixture of ammonium phosphate and a nitrogen-containing compound flame retardant is used, the proportion of the ammonium phosphate to the total amount of both is preferably at least 50% by mass or more. More preferably, it is at least 60% by mass.
- the amount of the flame retardant is small, so that it is necessary to add the amount exceeding 60 parts by mass from the viewpoint of flame retardancy, and the optical fiber cord is bent for a long time. In such cases, the habit tends to remain, which may hinder subsequent wiring work. In addition, the mechanical properties of the coating material significantly decrease.
