电缆堵水材料的开发研究

在电缆绝缘缆芯外挤包一层堵水材料，不仅可改善电缆的电气性能．而且可降低电缆材料的成本。研究开发的堵水材料的主要配方为：ＡＣＭ１００；硫化剂及其助剂１０．０－１２．０；氧化镁６．０－８．０；防老剂２．５－３．０；炭黑４０－４５；ＬＥＥ白滑粉及碳酸钙９５－１０５。同时还添加一定量的ＷＢ系列橡胶加工助剂。试验证明．橡胶的性能及加工工艺良好．经济效益和社会效益十分可观。

Development of Water Barrier of Electric Cable

A water barrier was extruded on the insulation layer of electric cable to improve electric property and to lower the cost. The formula of the water barrier was given as follows: ACM 100; curatives 10. 0- 12. 0; magnesium oxide 6. 0-8. 0; antidegradant 2. 5-3. 0;carbon black 40-45; slippery white powder Lee and calcium carbonate 90-105; A certainlevel of rubber processing aid WB series was also added into the compound. It was found throughthe test that good physical properties and processibility of water barrier,as well as significant economic and social benifits were obtained.
