Abstract

The embodiment of the present application provides a high-voltage cable insulation material and a preparation method thereof, the high-voltage cable insulation material comprises a blend prepared fromthe following parts by weight: 90 parts of isotactic polypropylene and 10 parts of a propylene-ethylene copolymer. The preparation method of the high-voltage cable insulation material comprises: mixing the granular isotactic polypropylene and the propylene-ethylene copolymer according to a ratio of 9:1, and then melting at 180 DEG C for 2 minutes; applying 1 ton of pressure for pressing for 1 minute; at 180 DEG C applying 5 tons of pressure for pressing for 3 minutes to obtain an initial film sample; and extracting the initial film sample. The high-voltage cable insulation material can satisfy an existing cross-linked polyethylene product, and improves the low toughness and low electrical performance of a polypropylene material. In addition, the high-voltage cable insulation material finished product has recyclability and no harm to the environment.

Description

technical field [0001] The present application relates to the technical field of composite cable materials, in particular to a high-voltage cable insulating material and a preparation method thereof. Background technique [0002] The basic structure of a power cable consists of four parts: a core (conductor), an insulating layer, a shielding layer and a protective layer. Among them, the insulating layer is used to electrically isolate the wire core from the ground and wire cores of different phases, and is an indispensable component to ensure power transmission. The insulating layer is made of insulating materials, commonly used insulating materials are oil-impregnated paper, plastic and rubber. [0003] High voltage cables generally refer to power cables above 110KV. Currently in high voltage cables, the widely used cable insulation material is XLPE (Cross Linked Polyethylene). XLPE has good dielectric and mechanical properties, but the material is not recyclable. With ...
