Description

一种碳酸钙粉状陶土的PVC材料护套
技术领域
本发明涉及电缆套管，具体涉及一种碳酸钙粉状陶土的PVC材料护套。 
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碳酸钙粉状陶土的PVC材料护套。 
为了实现上述目的，本发明是通过如下的技术方案来实现：其配方由60%-70%的PVC树脂、15%-40%的增塑剂、5%-10%的阻燃剂、2%-5%的增料、2%-5%的内外滑剂和2%-5%的稳定剂。 
作为优选，所述碳酸钙为粉状。 
作为优选，所述碳酸钙为活化重性碳酸钙。 
作为优选，所述氯化石蜡为液体状。 
作为优选，所述煅烧陶土为粉状。 
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。 
具体实施方式

本具体实施方式采用以下技术方案：碳酸钙粉状陶土的PVC材料护套，其配方由60%-70%的PVC树脂、15%-40%的增塑剂、5%-10%的阻燃剂、2%-5%的增料、2%-5%的内外滑剂和2%-5%的稳定剂。 
值得注意的是，所述碳酸钙为粉状。 
值得注意的是，所述碳酸钙为活化重性碳酸钙。 
值得注意的是，所述氯化石蜡为液体状。 
值得注意的是，所述煅烧陶土为粉状。 
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。 
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领 域的普通技术人员来说，在不脱离本发明技术原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
