| 中文摘要: |
| 以氯化聚乙烯（CPE）绝缘材料制备电线（称为CPE电线），研究防护蜡对CPE电线绝缘性能的影响。结果表明：与58#石蜡相比，防护蜡RW287，RW217和LSB20的结晶更小，形成的蜡膜更致密，其CPE电线的电阻更大，绝缘性能更好；添加防护蜡能明显增大CPE电线的电阻，防护蜡用量越大，CPE电线的电阻越大，绝缘性能越好，且温室放置和水浸泡时间越长，防护蜡对CPE电线的绝缘性能提升越大；适用温度范围更宽的防护蜡RW287和LSB20对CPE电线的防护效果较好，防护蜡LSB20对常温（25 ℃）下CPE电线的防护效果较好，防护蜡RW287对长期水浸泡条件下CPE电线的防护效果较优。 |

| Using polyvinyl choride（CPE） insulation materials to prepare wires（referred to CPE wires），the effect of protective waxes on the insulation performance of chlorinated polyethylene （CPE） wires was studied.The results showed that compared with 58# paraffin，the crystals of protective wax RW287，RW217 and LSB20 were smaller，the formed wax film was denser，so that the resistance of their CPE wires increased，the insulation performance was better.Adding protective wax could significantly increase the resistance of CPE wires.The larger the protective wax dosage amount was，the greater the resistance of CPE wires was，and the better the insulation performance was better.Moreover，the longer the room temperature storage and water immerdion time was，the greater the improvement of insulation performance of CPE wires by protective wax was.The protective wax LSB20 and RW287，which were suitable for a wider temperature range，had better protective effect on CPE wires.The protective wax LSB20 had better protective effect on CPE wires at normal temperature（25 ℃），while the protective wax RW287 had better protective effect on CPE wires under long-term water immersion conditions. |
