Low temperature resistance and torsion resistance sheathing materials for wind power cables and manufacture method thereof

Abstract

The invention provides a low temperature-resistance and torsion-resistance sheathing materials for wind power cables and a manufacture method thereof, and relates to chemical materials and a manufacture method. The sheathing materials for cables comprise the compositions of 100 parts of chlorinated polyethylene, 10-40 parts of a plasticizer, 50-100 parts of a reinforcing agent, 2.5-4 parts of a cross-linking agent, 1-3 parts of an auxiliary crosslinking agent, 2-4 parts of an anti-aging agent, 10-30 parts of a fire retardant, and 10-20 parts of an active agent. The manufacture method comprises the following steps of (1) selecting above-mentioned raw materials; (2) mixing the raw materials in an internal mixer; (3) performing a supplement mixing for the mixed raw materials in an open mixing machine, and sorting out films; and (4) putting in a rolling page machine to output the films, extruding to the cables, and obtaining cable sheathes after a sulfuration. The sheathing materials meet the requirements of 1440 degree torsion for 5000 cycles clockwise and counterclockwise under a low temperature of -40 DEG C, have good performances of torsion resistance, cold resistance, oil resistance, corrosion resistance, and the like, and pass the national CT10-4136 identification.

Description

Technical field [0001] The invention relates to a chemical material and a manufacturing method, in particular to a cable sheath material and a manufacturing method. Background technique [0002] At present, the cable sheathing material has poor performance such as torsion resistance, severe cold resistance, oil resistance, and corrosion resistance in a low temperature environment. The cables of wind turbines often work in low temperature environments, and the cables for wind power generation need to have excellent torsion resistance, cold resistance, oil resistance, and corrosion resistance. Therefore, it is necessary to invent a cable sheathing material that has the properties of torsion resistance, severe cold resistance, oil resistance, and corrosion resistance in a low temperature environment. Summary of the invention [0003] The purpose of the present invention is to provide a low-temperature-resistant torsion-resistant wind power cable sheath material and manufacturing met...
