摘要
采用氯丁橡胶（ＣＲ）作电缆护套材料时，共混一定量的氯化聚乙烯（ＣＰＥ）可明显改善其胶料耐热性，提高其定伸应力，拉伸强度及撕裂强度，且在一定程度上降低了生产成本。ＣＲ／ＣＰＥ用量比及硫化体系的选择是ＣＲ／ＣＰＥ电缆护套胶料研制的关键。试验表明：ＣＲ／ＣＰＥ用量比在７０／３０～６０／４０范围内，选用ＮＡ－２２／ＤＰＴＴ并用作硫化体系时，电缆护套胶料的性能较好，符合ＧＢ７５０４和ＧＢ９３３１标准要求。
When CR being used for the material of cable sheath,blending a certain quantity CPE could develop the resistance to heat,modulus,tensile strength and tear strength,and the manufacture cost is reduced in a certain exrtent.The key of developing CR/CPE cable sheath compound are CR/CPE ratio and the selection of curing system.The test results have shown that when CR/CPE ratio is within 70/30～60/40,combined NA-22/DPTT is selected as curing system,the cable sheath materials characteristics is better and meets GB 7504 and GB 9331 standard requirement.
