摘　　要：针对全海深工作环境对深海电缆护套用橡胶材料的使用性能要求,研究氯丁橡胶(CR)胶料和CR/天然橡胶(NR)并用胶的物理性能、绝缘性能、耐海水老化性能和挤出性能。结果表明:与牌号为Denka Chloroprene A-90的硫黄调节型和牌号为CR322的混合调节型CR相比,牌号为CR232的非硫黄调节型CR物理性能优异,更适合用作深海电缆护套胶料的主体材料;CR/NR并用胶(并用比80/20)的绝缘性能好,体积电阻率可达1.3×1012Ω·cm,且物理性能和耐海水老化性能好;以固体古马隆树脂/白油膏为增塑剂的CR/NR并用胶挤出表面光滑、挤出膨胀率小,是深海电缆护套的优选橡胶材料。According to the performance requirements of the rubber materials for the deep sea cable sleeve in all deep-sea working environments,the physical properties,insulation performance,seawater aging resistance and extrusion properties of chloroprene(CR)compound and CR/natural rubber(NR)blends were studied.The results showed that,compared with the sulfur regulated CR Denka Chloroprene A-90 and mixed regulated CR322,the non sulfur regulated CR232 possessed excellent mechanical properties,and it was more suitable to be used as the main material of the deep sea cable sleeve compound.The insulation performance of CR/NR blend(blending ratio was 80/20)was good,the volume resistivity could reach 1.3×1012Ω·cm,and the physical properties and seawater aging resistance were excellent.The CR/NR blend with solid coumarone/white factice as plasticizers had smooth extruded surface and small extrusion swell ratio,which was a good choice of rubber materials for the deep sea cable sleeve.
