- Extruded to a cable Extruded to a cable (extrusion conditions from 240 to 250 °C (feeder (material feeder) temperature is 240 °C, the rest of the temperature is 250 °C and the speed 80 rpm, 30 m / min (min. ), And the properties of the specimens were evaluated, and the results are also shown in Table 1 below.
- VW-1 Flame retardancy
- -Melt index (g / 10min.): Measured based on ASTM D1238, measured in 1 minute after 4 minutes of stay at 250 °C and 10kg load for 1 minute.
- PPE polyphenylene ether
- PX-100F from Mitsuishi Engineering Plastic (MEP), Japan
- SBC 1 styrene block copolymer
- Kraton SEBS G 1657 (13% styrene), United States
- SBC 2 styrene block copolymer
- Kraton SEBS A 1536 42% styrene
- PP polypropylene
- EC5082 EBR (ethylene butadiene rubber) content of Korea 7%, Melt index: 23g / 10min.
- FR1 metal phosphate as second phosphorus flame retardant; Aluminum diehtylphosphate; Clariant OP 1230 in Japan (phosphorus content 23-24%)
- FR2 Melamine Polyphosphate as nitrogen-based flame retardant; DOOBON NONFLA 601, South Korea (nitrogen content 39-42%, phosphorus content 14-17%)
- FR3 bisphenol-A-diphenylphosphate (BPADP) as a room temperature liquid phosphorus flame retardant; Adeka FP-600 in Japan
- Example 1 As shown in Table 1, in the case of the resin compositions according to the present invention (Examples 1 and 5), it was confirmed that it has excellent flame retardancy while having a proper melt index, and also other mechanical properties such as tensile strength and elongation It has also been found to be particularly useful in the manufacture of electrical wires, including cables that require excellent workability and flame retardancy at the same time. On the other hand, in the case of Comparative Example 1 containing too much room temperature liquid-based phosphorus-based flame retardant, it was confirmed that the negative effect on the mechanical properties (elongation) at the same time increasing the hardness.
- the flame retardant resin composition according to the present invention is excellent in extrudability and excellent mechanical properties by imparting excellent flame retardant properties by using a liquid flame retardant at room temperature in an appropriate amount. It was confirmed that it is suitable for the production of electric wires, including various molded articles, in particular, cables that require.
