Abstract

本发明涉及一种高韧性PE管材,该PE管材由质量分数为84%~90%的聚乙烯原料、2.5%的母粒、8%~10%的超细轻质碳酸钙粉组成,本发明通过将超细轻质碳酸钙粉添加到材料中去,添加了超细轻质碳酸钙一方面可降低PE管材的成本,而且填充碳酸钙后,由于碳酸钙的硬度大,会提高塑料制品的硬度和刚度,力学性能增强。同时在材料中添加由聚乙烯、硅酸钙晶须或者硫酸钙晶须、硅烷偶联剂、马来酸酐相容剂、其他助剂制成的母粒,进一步地增强了其抗拉强度、刚性,也就是增强了其韧性。

Description

一种高韧性PE管材
技术领域
本发明涉及一种管材,尤其涉及一种具有高韧性的PE管材。
背景技术
PE管主要用于输送气态的人工煤气、天然气、液化石油,还有排污,施工工艺简单,PE管材具有强度高、耐高温、抗腐蚀、无毒、耐磨、有一定的柔韧性性能。聚乙烯的分子是长链线型结构或支结构,为典型的结晶聚合物。在固体状态下,结晶部分与无定型共存。结晶度视加工条件和原处理条件而异,一般情况下,密度高结晶度就越大。L.DPE结晶度通常为55%-65%,HDPF结晶度为80%-90%。聚乙烯为典型的热塑性塑料,由于其具有无臭、无味、无毒的特点,受到推广普及使用。但是在一些环境较恶劣的环境中,或一些其他的重要设施工程中,针对承载量更大或是更重的一些重要场所,PE管的抗拉强度并没有到达要求,不能满足实际生产及使用。
发明内容
本发明所要解决的技术问题在于:提供一种高韧性PE管材,所述高韧性PE管材能解决PE管材抗拉强度不高的问题,增加了其强度和刚性,提高其韧性。
为解决上述问题,本发明的技术方案是提供一种高韧性PE管材,所述高韧性PE管材由80%~85%的聚乙烯原料、2.5%的母粒组成。
进一步地,所述高韧性PE管材添加有8%~10%的超细轻质碳酸钙粉。
进一步地,所述母粒主要为:
重量比例为0.5%~1%的聚乙烯
重量比例为1.25%~1.5%的晶须
重量比例为0.025%~0.05%的硅烷偶联剂
重量比例为0.025%~0.035%的相容剂
重量比例为0.001~0.005的其他助剂
进一步地,所述晶须为硅酸钙晶须、硫酸钙晶须中的一种或者二者任意比例的混合物。
进一步地,所述相容剂为马来酸酐。
进一步地,所述稳定剂、聚乙烯原料和母粒混合后的物料经过双螺杆挤出机挤出成形管材。
与现有技术相比,本发明通过将超细轻质碳酸钙粉添加到材料中去,增强了PE管材成品的抗拉强度、刚性,同时在材料中添加由聚乙烯、硅酸钙晶须或者硫酸钙晶须、硅烷偶联剂、马来酸酐接枝相溶剂、其他助剂制成的母粒,进一步地增强了其抗拉强度、刚性,也就是增强了其韧性。
具体实施方式
本发明所阐述的一种高韧性PE管材,由80%~85%的聚乙烯原料、2.5%的母粒、8%~10%的超细轻质碳酸钙粉组成,将聚乙烯原料和母粒、超细轻质碳酸钙粉混合后的物料先经过碾磨成粉末状、再经过过高低速搅拌、随后经过双螺杆挤出机挤出成形、冷却即可得到成品。在原材料中的母粒由以下成分构成:
重量比例为0.5%~1%的聚乙烯
重量比例为1.25%~1.5%的晶须
重量比例为0.025%~0.05%的硅烷偶联剂
重量比例为0.025%~0.035%的马来酸酐接枝相容剂
重量比例为0.001~0.005的其他助剂;
其中的晶须为硅酸钙晶须、硫酸钙晶须中的一种或者二者任意比例的混合物。
在制备PE管材过程中,添加了超细重质碳酸钙一方面可降低PE管材的成本,同时填充碳酸钙后,由于碳酸钙的硬度大,会提高塑料制品的硬度和刚度,力学性能增强。制品的抗拉强度和抗弯强度得到改进,并使塑料制品的弹性模量显着提高,增强了PE管材的韧性。同时还采用有上述配比的母粒也进一步地增强了其刚性、韧性。
以上对本发明的一个实施例进行了详细说明,但所述内容仅为本发明创造的较佳实施例,不能被认为用于限定本发明创造的实施范围。凡依本发明创造申请范围所作的均等变化与改进等,均应仍归属于本发明的专利涵盖范围。
