摘要

目的基于热重分析方法,系统探究镀锡与镀银铜合金导体ETFE绝缘电线的热降解规律。方法结合时温等效原理与阿伦尼乌斯方程,构建ETFE绝缘电线的加速老化模型。提出一种适用于ETFE绝缘电线的老化寿命评估方法,并设计加速老化试验,验证其对产品寿命的可靠性。结果 ETFE绝缘材料热质量损失过程可分为低温挥发、高温分解和残留稳定3个阶段。由于导热滞后效应,升温速率的提高显著延迟了热降解温度,镀银与镀锡导体的热稳定性差异较小。采用构建的ETFE绝缘电线老化寿命评估方法,得出了ETFE绝缘电线60 ℃加速老化寿命与25 ℃老化寿命的等效关系,并验证了60 ℃条件下的绝缘线缆寿命。结论本研究提出的ETFE绝缘电线热稳定性评价体系与寿命验证评估方法,为高温电缆的质量控制、规范验收等提供了科学方法,在航空装备等领域具有一定的工程应用价值。

Abstract

Based on the thermogravimetric analysis method, the work aims to systematically investigate the thermal degradation laws of ETFE insulated wires for tin-plated and silver-plated copper alloy conductors. By combining the time-temperature equivalence principle and the Arrhenius equation, an accelerated aging model for ETFE insulated wires was constructed. A method for verifying and evaluating the aging lifespan of ETFE insulated wires was proposed, and an accelerated aging test was designed to verify the reliability of the product lifespan assessment. The thermogravimetric analysis results showed that the thermal weight loss process of ETFE insulated materials could be divided into three stages of low-temperature volatilization, high-temperature decomposition, and residual stability. Due to the thermal conduction lag effect, the increase in the heating rate significantly delayed the thermal degradation temperature. The thermal stability difference between silver-plated and tin-plated conductors was relatively small.By using the constructed aging lifespan assessment method for ETFE insulated wires, the equivalent relationship between the accelerated aging lifespan at 60 ℃ and the aging lifespan at 25 ℃ of ETFE insulated wires is obtained, and the lifespan of insulated wires at 60 ℃ is verified. The thermal stability evaluation system and lifespan verification assessment method for ETFE insulated wires proposed in this study provide a scientific method for the quality control and standardized acceptance of high-temperature cables and have certain engineering application value in fields such as aviation equipment.
