Title:
INSULATING MATERIAL COMPOSITION AND INSULATING MATERIAL PREPARED USING SAME
Document Type and Number:
WIPO Patent Application WO/2020/022651
Kind Code:
A1
Abstract:
The present invention relates to an insulating material composition and an insulating material prepared using same, wherein the insulating material composition comprises 50-90 wt% of polypropylene and 10-50 wt% of styrene-based elastomer, and the insulating material composition is prepared as an insulating material and then the insulating material is coated on a conductor of a power cable by extrusion processing to form an insulating layer. In the present invention, by preparing an insulating material without a cross-linking reaction, cross-linking byproducts are not generated and thus, problems such as degradation of insulation performance of a power cable do not arise, mechanical properties are secured due to the efficient mixing ratio of polypropylene and styrene-based elastomer, and extrusion processability is also facilitated.
