Description

PVC绝缘材料的配方及其加工工艺
技术领域
本发明公开了一种PVC绝缘材料的配方及其加工工艺。
背景技术
PVC即聚氯乙烯，是由氯乙烯在引发剂作用下聚合而成的热塑性树脂，是氯乙烯的均聚物。PVC是通用型树脂，价格低廉、加工方便，它和助剂配合制得制品具有重量轻、强度高，耐化学药品性好，电绝缘性能和耐老化性能、防水防腐性能皆优，是电线电缆较理想的包覆材料。
二十世纪三四十年代国外就开始采用软PVC作为电线的绝缘材料，我国PVC电缆料的开发始于五十年代，然而，随着通讯事业的迅猛发展，对PVC绝缘性能的要求也越来越高，对PVC绝缘性能的改进技术的研究也越来越深入。
发明内容
本发明解决其技术问题所采用的技术方案是：一种PVC绝缘材料的配方，所述配方按重量份含有如下组分：PVC树脂100份，氯化石蜡40-60份，DOP30-50份，氧化钙1-5份，氧化镁1-5份，锡酸锌0.1-1.5份，环氧化油2-5份。
本发明的目的之一还在于提供本发明所述配方的加工工艺，包括如下步骤：
(1)按组成原料的重量份称取各原料，将所有原料加入混合机中混合均匀，控制混合机温度在70-85℃下先低速混合10-12min，然后再高速混合2-3min，然后在150℃下进行一次塑化，切粒，风冷；
(2)将步骤(1)的风冷料在109℃下进行二次塑化，切粒、风冷、检测后包装。
本发明的有益效果是：本发明制得的绝缘材料绝缘性能优异并且综合性能稳定。
具体实施方式
具体实施例：一种PVC绝缘材料的配方，所述配方按重量份含有如下组分：PVC树脂100份，氯化石蜡40-60份，DOP30-50份，氧化钙1-5份，氧化镁1-5份，锡酸锌0.1-1.5份，环氧化油2-5份。
本发明还在于提供本发明所述配方的加工工艺，包括如下步骤：
(1)按组成原料的重量份称取各原料，将所有原料加入混合机中混合均匀，控制混合机温度在70-85℃下先低速混合10-12min，然后再高速混合2-3min，然后在150℃下进行一次塑化，切粒，风冷；
(2)将步骤(1)的风冷料在109℃下进行二次塑化，切粒、风冷、检测后包装。
本发明的有益效果是：本发明制得的绝缘材料绝缘性能优异并且综合性能稳定。
显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本发明创造的保护范围之中。
