Description

一种新型聚丙烯管道及加工工艺
技术领域
本发明属于管材技术领域,具体涉及一种新型聚丙烯管道及加工工艺。
背景技术
传统的生产技术基本采用单螺杆挤出工艺技术,具有能耗高,产量低,制品成本高昂的劣势,为解决以上问题,通过多年的技术经验的积累,设计出一种新型的聚丙烯管道及其生产工艺技术。
发明内容
本发明的目的是为了克服现有技术的不足,而提供一种混炼效果好、产品质量优成本低的新型聚丙烯管道及加工工艺。
本发明的目的是这样实现的:一种新型聚丙烯管道,其特征在于:以重量份计,原料包含有:PP树脂:95份;碳酸钙:5份;色母或PE蜡:2份。
它由以下原料组成:PP树脂、碳酸钙、色母;所述的碳酸钙为碳酸钙填充母粒。
它由以下原料组成:PP树脂、碳酸钙、PE蜡;所述的PP树脂为PP粉,所述的碳酸钙为1000目-1400目的超细重钙,所述的原料中还包括有钛酸酯偶联剂:2份和抗老化剂:0.5份;
所述的聚丙烯管采用普通螺旋式混色机混合10-15min,使各组分分散均匀,经真空吸料装置传送至双螺杆挤出机,料筒温度196℃-205℃;模具温度设定200℃-210℃。
所述的聚丙烯管采用普通螺旋式混色机混合15-20min,使各组分分散均匀,经螺旋上料机传送至双螺杆挤出机,料筒温度175℃-195℃;模具温度设定200℃-210℃。
本发明的有益效果:本发明采用双螺杆挤出工艺,配合本发明中的配方,相比现有单螺杆挤出工艺,能够有效降低能耗,提高产品质量,降低产品的生产成本,本发明虽然增加填充,由于碳酸钙与PP分子链的相互协同作用,不仅没有对自身的环刚度产生任何影响,而且使PP材料的断裂伸长率提高了30%。
附图说明
图1是本发明一种新型聚丙烯管道及加工工艺的工艺流程图。
