Example Embodiment

[0184] [Example 1]

[0185] 36% by mass of chlorinated polyolefin resin (A-1) and polyolefin resin (B-1) at 170°C using a twin-screw extruder (model name "BT-40", manufactured by the Institute of Plastics Engineering) 25% by mass, flame retardant (C-1) 21% by mass, auxiliary flame retardant (D-1) 6% by mass, auxiliary flame retardant (D-2) 3% by mass, heat stabilizer (E-1) 5% by mass, 1.5% by mass of antioxidant (F-1), 1.5% by mass of lubricant (G-1), and 1% by mass of pigment (H-1) were melt-kneaded to obtain a resin composition.

[0186] The obtained resin composition was supplied to a right-angle head 40mm optical cable coating device for resin coating (manufactured by Sei Seisakusho Co., Ltd.), and a coating layer with a thickness of 0.6 mm was coated on the outer circumference of the optical fiber to obtain a diameter of 2.2 mm Optical cable. The above-mentioned test was performed on the obtained optical cable. The evaluation results are shown in Table 2.

Example

[0187] [Examples 2-13, Comparative Examples 1-6]

[0188] Except having changed the composition of the resin composition as shown in Table 1, it carried out similarly to Example 1, and obtained the optical cable. Table 2 shows the evaluation results of the obtained optical cable. It should be noted that the unit of each numerical value in Table 1 is mass %.

[0189] [Table 1]

[0190]

[0191] [Table 2]

[0192]

[0193] The optical cables obtained in Examples 1 to 13 are excellent in flame retardancy, long-term heat resistance, and mechanical properties.

[0194] On the other hand, the optical cables obtained in Comparative Examples 1, 2, 4, and 5 that did not contain the polyolefin resin (B) had poor long-term heat resistance and mechanical properties. In addition, the optical cables obtained in Comparative Examples 3 and 6 that did not contain the chlorinated polyolefin resin (A) had poor flame retardancy and mechanical properties.

Abstract

Provided is an optical fiber cable having excellent flame retardancy, long-term heat resistance and mechanical characteristics. An optical fiber cable according to the present invention comprises an optical fiber and a cladding layer that is provided on the outer circumference of the optical fiber. The cladding layer contains a chlorinated polyolefin resin (A) and a polyolefin resin (B).

Description

technical field [0001] The invention relates to optical cables and sensors. Background technique [0002] Optical fibers are widely used in communication, sensors, lighting, decoration, display and other purposes. Glass-based optical fibers have excellent optical conductivity over a wide wavelength range, but have problems such as poor processability and mechanical properties. On the other hand, the plastic optical fiber includes, for example, an optical fiber having a structure in which a core made of a high-transparency resin such as polymethylmethacrylate is coated with a high-transparency resin having a lower refractive index than the core. made of the periphery. Compared with glass-based optical fibers, plastic optical fibers are characterized by superior processability and flexibility. In addition, with the improvement of manufacturing technology in recent years, the transmission distance of plastic optical fiber has become longer, and its use has gradually become w...
