Preparing method for wire coating layer

Abstract

The invention discloses a preparing method for a wire coating layer. A same-layer coating layer is prepared with thermoplastic plastic and thermosetting plastic, and when a next-layer coating layer isprepared, directions stacked at this time rotate 90 degrees in the Z-shaft direction; according to the requirements, multiple layers of coating layers are sequentially prepared, and are of spiral structures in the length direction; after multiple layers of the coating layers are completed, thermoplastic treatment is carried out through a press fit mold, then cooling is carried out, and the wire coating layer is obtained. The wire coating layer prepared with the method has enough strength to protect copper wires arranged in the wire coating layer, it is avoided that the wires are snapped whenthe wires suffer from the tension effect, and the service life is effectively prolonged; through the thermosetting plastic, the wire coating layer has the enough shaping, multiple times of folding andwinding of the wires can be met, and the preparing method for the wire coating layer can be applied to wires, cables, earphone cables and various pipes.

Description

technical field [0001] The invention relates to the technical field of electric wire covering layers, in particular to a method for preparing electric wire covering layers. Background technique [0002] At present, the covering layers of electric wires and earphone cables on the market are all made of the same material or multi-layer co-extrusion technology of multiple materials. There is only one material for the same layer, and because the covering layers of electric wires or earphone cables require It has good shape, so that the cladding layer will not break after being folded or wound several times, but it increases the shaping of the cladding layer, and the strength of the cladding layer copper wire is not high. When the wire is subjected to tension, the cladding layer The coating is greatly deformed, so that the copper wire is directly subjected to tension, which in turn causes the copper wire to break, making the entire wire or earphone unable to work normally and scr...
