Description
技术领域
本发明属于电缆料技术领域,具体涉及一种耐油EVA电缆料及其制备工艺。
背景技术
随着工业的发展,耐油电缆在我国的石油、化工、海洋和轨道交通等领域中的应用越来越普遍。近年来,由于电缆耐油性差而引起的事故呈上升趋势。各个领域对电缆料耐油性的需求始终没有得到很好的解决。
目前,电线电缆行业中,制造无卤阻燃的聚合物大多采用聚烯烃材料,尤其以乙烯-醋酸乙烯酯共聚物(EVA)为主,由于它熔融温度较低,流动性好,有极性又无卤元素,可与多种聚合物和矿物粉相容,多项机械物理性能、电气性能和加工性能平衡,且价格不高、市场供应充分。但是,EVA的耐油性能与VA含量直接相关,VA含量越高,耐油性越好。而VA含量超过50%的橡胶型EVM,都被国外某企业独霸,且售价是VA含量与之相近牌号的2~3倍。当前,国内电缆行业用量最大的无卤阻燃基料主要为低VA含量(10-28%)的EVA树脂(如美国杜邦的EVA265#)。
为此,针对当前EVA的使用现状,迫切需要一种提高耐油性的电缆材料及其方法。
发明内容
本发明为了解决上述技术问题,提供了耐油EVA电缆料。本发明通过对低VA含量的EVA进行接枝改性,有效的提高了EVA电缆料的耐油性。
为实现上述发明目的,本发明采用如下的技术方案:
一种耐油EVA电缆料,其特征在于,所述电缆料的各组分及重量份数包括:
乙烯基硅烷/苯乙烯接枝乙烯-醋酸乙烯共聚物50-70份,
聚苯醚树脂5-20份,
阻燃剂15-30份,
偶联剂1-5份;
所述的乙烯-醋酸乙烯共聚物的VA含量为10%-28%。
所述的乙烯基硅烷/苯乙烯接枝乙烯-醋酸乙烯共聚物采用熔融挤出法在引发剂的作用下制备,其中乙烯-醋酸乙烯共聚物、乙烯基硅烷和苯乙烯的质量投料比为100:1-5:4-10。
所述的引发剂为DCP或BPO。
所述熔融挤出设备为双螺杆挤出机,熔融接枝温度为195-220℃,螺杆转速为50-100rpm。
所述的阻燃剂为氢氧化铝、氢氧化镁、硼酸锌、氧化锑和钼化合物中的一种或多种。
所述的偶联剂为硅烷偶联剂、铝酸酯偶联剂、磷酸酯偶联剂和硼酸酯偶联剂中的一种或多种。
一种采用上述耐油EVA电缆料制备的电缆。
一种上述耐油EVA电缆料的制备工艺,其特征在于,包括如下步骤:
首先,将阻燃剂和偶联剂在高速混合机中混合均匀,而后将乙烯基硅烷/苯乙烯接枝乙烯-醋酸乙烯共聚物和聚苯醚树脂加入到高速混合机中进行共混,最后将上述混合均匀的原料经双螺杆挤出机在190-250℃的条件下挤出,冷却、干燥、切割造粒,即可得到耐油EVA电缆料成品。
本发明的有益效果在于:
1、本发明选用乙烯基硅烷和苯乙烯对低VA含量的EVA进行改性,提高了EVA的耐油性。
2、选用聚苯醚树脂与乙烯基硅烷/苯乙烯接枝乙烯-醋酸乙烯共聚物复配,使得电缆料的耐油性、阻燃性以及机械性能均优于丁腈橡胶或聚氯乙烯或聚酰胺的复配体系。
3、本发明的电缆料在耐油、阻燃以及机械性能方面均可与高VA含量的EVA(含量大于55%)相媲美,其优良的性价比可取代部分售价高的VA含量高的EVA在电缆中的应用。
