电缆用的辐射交联阻燃包覆组合物的制备方法
摘要：
本发明提供了一种辐射交联阻燃包覆组合物的制备方法，包括下列步骤：(1)由一部分基础树脂和阻燃剂制成阻燃母粒；(2)将所述的阻燃母粒与其余一部分基础树脂、抗氧剂、任选的阻燃增效剂以及任选的其他添加剂混合，挤出造粒，然后成型，由此得到成形体；(3)将步骤(2)中得到的成形体在30-120KGy的剂量下进行辐射交联，由此得到辐射交联的阻燃包覆组合物。
摘要（英）：

The invention provides a preparation method of radiation-crosslinked and flame-retardant coating composition for a cable. The preparation method comprises the following steps: (1) preparing flame-retardant master batch from one part of base resin and a flame retardant; (2) mixing the flame-retardant master batch with the other part of base resin, an antioxidant, an optional flame retardant synergist and another optional additives, and performing extrusion granulation and forming to obtain a formed body; (3) performing radiation crosslinking on the formed body obtained in the step (2) at the dose of 30-120 KGy to obtain the radiation-crosslinked and flame-retardant coating composition.
