Description

一种半柔性PVC弹性护套
技术领域
本发明涉及电缆套管，具体涉及一种半柔性PVC弹性护套。 
背景技术
目前工程用电缆套管是以聚氯乙烯树脂为主料、重质碳酸钙为填料、及氯化聚乙烯、石蜡等小料混合制成，并具备一定的耐腐蚀、耐高温、阻燃、绝缘耐磨重量轻、无污染等特性。但其不足之处是抗压强度差，与施工应用要求还有差距，其阻燃性能也不够理想；另外其维卡软化温度徘徊在90℃左右，内外管壁摩擦系数大等，增加了施工使用的难度。 
发明内容
针对现有技术上存在的不足，本发明目的是在于提供一种性能优良的半柔性PVC弹性护套。 
为了实现上述目的，本发明是通过如下的技术方案来实现：其配方为PVC三型75g、活性炭45g、DOP45g、DOS3g、氯腊20g、稳定剂2.8g、硬脂酸0.6g、MBS9g、石蜡1g制作而成。 
作为优选，所述增塑剂为DINP。 
作为优选，所述稳定剂包括光稳定剂和热稳定剂。 
作为优选，所述光稳定剂为紫外线吸收剂。 
作为优选，所述热稳定剂为钙剂。 
作为优选，所述热稳定剂为金属皂类。 
本发明产品具有耐高温和抗老化性能好，能适应电力电缆使用过程因过载短路而产生的高温，材料具有高绝缘强度和体积电阻率；柔性好且抗压强度大、抗不均匀沉降，在施工现场无须包封浇混凝土；内壁表面磨擦系数小，利于使用，产品寿命长。 
下面结合具体实施方式来详细说明本发明。
