Abstract

The invention discloses an X-ETFE (crosslinked ethylene-tetrafluoroethylene) insulating wire or cable with spiral stripe identifications for aerospace and a preparation process for the insulating wire or cable. The preparation process for the insulating wire or cable includes steps of: printing spiral stripe identifications on an insulating layer of an X-ETFE insulating wire directly formed by a single insulating core wire; printing spiral stripe identifications on a sheath layer of an X-ETFE insulating cable formed by a single insulating core wire, a shielding layer and the sheath layer; printing spiral stripe identifications on an insulating layer and/or a sheath layer of an X-ETFE insulating cable formed by a plurality of insulating core wires, the shielding layer and the sheath layer; and printing spiral stripe identifications on an insulating layer and/or a sheath layer of an X-ETFE insulating cable formed by a plurality of insulating core wires and the sheath layer. The insulating core wires consist of conductors and the insulating layers which wrap the conductors. The X-ETFE insulating wire or cable with the spiral stripe identifications for aerospace is easy to be distinguished and identified, convenient to trace back and rapid in checking, and is beneficial to waste wire recovery. In addition, the X-ETFE insulating wire or cable with the spiral stripe identifications for aerospace has excellent high-temperature resistance, low-temperature resistance and radiation resistance, and the mechanical performance of the insulating layer is quite good.

Description

technical field [0001] The invention relates to a spiral stripe marking X-ETFE insulated wire and cable for aerospace and a preparation process thereof. Background technique [0002] The wire and cable industry is the second largest industry in China after the automobile industry, and the product variety satisfaction rate and domestic market share both exceed 90%. Worldwide, China's wire and cable output has surpassed that of the United States, becoming the world's largest producer of wire and cable. With the rapid development of my country's wire and cable industry, the number of new enterprises is increasing, the product categories are becoming more and more diversified, and the classification and recycling of products will become more complicated. [0003] In recent years, the wire and cable industry has more clearly defined the "green" product standards. Product standards such as halogen-free, low-smoke, flame-retardant, and lead-free have become the trend of new envir...
