Problems solved by technology
However, for ordinary PVC wires, the use temperature is limited. For wires with unlimited use temperature, the resist will also undergo thermal degradation under high temperature conditions, which cannot achieve both high temperature resistance and corrosion resistance; at the same time, it will decompose and release when burned. Black smoke, and highly toxic and corrosive gases such as hydrogen chloride, are the main causes of death in fires

Embodiment Construction
[0019] Below in conjunction with accompanying drawing and specific embodiment the present invention will be further described:
[0020] Such as figure 1 , figure 2 and image 3 As shown, the hydrolysis-resistant and high-temperature-resistant electric wire includes a core wire and a sheath 3. The core wire is a conductor 1 formed by twisting multiple bare copper wires and an insulating layer 2 of radiation-free low-smoke and halogen-free material outside the conductor 1. Composition, the TPU material sheath 3 is covered outside the core wire.
[0021] A method for preparing a hydrolysis-resistant and high-temperature resistant electric wire includes the following steps:
[0022] (1), a plurality of strands of bare copper wires are twisted together to form a stranded conductor 1;
[0023] (2) Overlay the insulation layer 2 of radiation-free low-smoke and halogen-free material on the outside of the stranded conductor 1 to make a core wire;
[0024] (3) Overlapping the shea...

The invention belongs to the field of transmission data lines of calorimeters of heating pipelines, and relates to a hydrolysis-resisting high-temperature resisting wire and a preparation method thereof. The wire comprises a core wire and a sheath. The core wire is formed by a conductor formed by twisting multiple strands of bare copper filaments and an irradiation-free low-smoke zero-halogen insulation layer outside the conductor. The sheath is made of TPU materials and covers the core wire. The wire is low in cost, environmentally-friendly, high-temperature resisting, hydrolysis-resisting, not liable to mildewing and widely used as a transmission data line of a calorimeter of a heating pipeline.
Description
technical field [0001] The invention relates to a data transmission line for a heat meter of a heating pipeline, in particular to a hydrolysis-resistant and high-temperature resistant wire and a preparation method thereof. Background technique [0002] Heating pipeline heat meter transmission data lines are required to have high temperature resistance and hydrolysis resistance. However, for ordinary PVC wires, the use temperature is limited. For wires with unlimited use temperature, the resist will also undergo thermal degradation under high temperature conditions, which cannot achieve both high temperature resistance and corrosion resistance; at the same time, it will decompose and release when burned. Black smoke, and highly toxic and corrosive gases such as hydrogen chloride, are the main causes of death in fires. Therefore, it is imperative to find suitable insulating materials while ensuring the quality of wires. Contents of the invention [0003] The purpose of the...
