摘要

基体树脂的类型决定了半导电屏蔽材料（SCSM）的使用性能，是实现电力电缆半导电屏蔽层功能的最关键部分。本研究选取了电力电缆半导电屏蔽层中常用的典型基体树脂，即乙烯-醋酸乙烯酯（EVA）、乙烯-丙烯酸丁酯（EBA）和乙烯-丙烯酸乙酯（EEA），重点分析了基体树脂的微观结构和性能特点，系统探讨了基体树脂对半导电屏蔽层综合性能的影响。研究结果表明，与 EVA 相比，EBA 和 EEA 都具有更高的分子量和结晶度，熔点更高，热稳定性更好。以 EBA 为基础的 SCSM 具有最佳的体积电阻率和表面光滑度。综合分析表明，EBA 是用于电力电缆中 SCSM 的理想基体树脂。这项研究有望为选择 SCSM 原材料和开发电力电缆提供理论依据。

A comprehensive analysis of vinyl-based matrix resins used in semi-conductive shielding materials for power cables

The type of matrix resin determines the service performance of the semi-conductive shielding materials (SCSMs) and serves as the most critical component for achieving the functionality of the semi-conductive shielding layer in power cables. This work selects the typical matrix resins commonly used in SCSM of power cables, namely ethylene–vinyl acetate (EVA), ethylene-butyl acrylate (EBA), and ethylene-ethyl acrylate (EEA), emphatically analyzes the microstructure and performance characteristics of the matrix resins, and systematically explores the impact of matrix resin on the comprehensive performance of SCSM. The research findings indicate that, compared to EVA, both EBA and EEA exhibit higher molecular weights and crystallinity, as well as enhanced melting points and superior thermal stability. The EBA-based SCSM demonstrates optimal volume resistivity and surface smoothness. Comprehensive analysis suggests that EBA is the ideal matrix resin for SCSM in power cables. This research is expected to provide a theoretical basis for the selection of raw materials for SCSMs and the development of power cables.

期刊介绍： Journal of Polymer Research provides a forum for the prompt publication of articles concerning the fundamental and applied research of polymers. Its great feature lies in the diversity of content which it encompasses, drawing together results from all aspects of polymer science and technology. As polymer research is rapidly growing around the globe, the aim of this journal is to establish itself as a significant information tool not only for the international polymer researchers in academia but also for those working in industry. The scope of the journal covers a wide range of the highly interdisciplinary field of polymer science and technology, including: polymer synthesis; polymer reactions; polymerization kinetics; polymer physics; morphology; structure-property relationships; polymer analysis and characterization; physical and mechanical properties; electrical and optical properties; polymer processing and rheology; application of polymers; supramolecular science of polymers; polymer composites.
