辐照交联EPDM绝缘橡皮及其制备方法
摘要：
本发明涉及一种辐照交联EPDM绝缘橡皮及其制备方法，组成及配比以质量份计为：三元乙丙橡胶A 80～20份；三元乙丙橡胶B 20～80份；敏化剂2～5份；防粘剂1～3份；离模剂1～3份；润滑助剂1～3份；活性剂5～10份；抗氧剂1～3份；增塑剂5～10份；补强剂50-60份；填充剂50～70份。本发明采用了新的硫化方式——辐照的交联方式，完全避免了现有采用直接蒸汽管道硫化的方式所带来的铜丝氧化、电缆进水与电缆表面污染等问题。
摘要（英）：

The invention relates to an irradiation cross-linking EPDM (Ethylene-Propylene-Diene Monomer) insulating eraser and a preparation method thereof. The irradiation cross-linking EPDM insulating eraser comprises ingredients in parts by weight: 80-20 parts of EPDM A, 20-80 parts of EPDM B, 2-5 parts of sensitizer, 1-3 parts of anti-sticking agent, 1-3 parts of release agent, 1-3 parts of lubricating auxiliaries, 5-10 parts of active agent, 1-3 parts of antioxidant, 5-10 parts of plasticizer, 50-60 parts of reinforcing agent, and 50-70 parts of filling agent. According to the irradiation cross-linking EPDM insulating eraser and the preparation method thereof, by adopting a new sulfuration mode, namely irradiation cross-linking mode, the problems that the existing direct steam pipeline sulfuration mode causes the oxidation of a copper wire, water of a cable and surface pollution to the cable and the like can be thoroughly avoided.
