Description

一种熔喷过滤材料及其制备方法
技术领域
本发明涉及过滤材料技术领域，尤其是一种熔喷过滤材料及其制备方法。
背景技术
现有技术中，对于聚丙烯熔喷后形成的过滤材料，其材料比较柔软，硬挺度不高，所以使用过程中具有很大的限制，尤其是打折后没有挺度，对材料折叠成型后，使用效果差。
发明内容
本发明为了解决上述技术不足而提供一种熔喷过滤材料及其制备方法，其能有效增加材料的硬度及韧性，提升性能。
本发明公开了一种熔喷过滤材料，包括聚丙烯、水柱极母粒、碳酸钙、增韧剂，其中各组分的质量分数为：聚丙烯100分、水柱极母粒1-4份、碳酸钙7-20份、增韧剂2-10份。其中增韧剂为梦色丽(上海)材料科技有限公司生产的F82型号增韧剂。
所述聚丙烯的容值为1500-1800g/10min。
所述碳酸钙的颗粒粗细为1000-3000目。
一种熔喷过滤材料的制备方法，将聚丙烯、水柱极母粒、碳酸钙、增韧剂称量混合后加入挤出机料仓，混合料在料仓烘干后进入挤出机，挤出机的1-7区温度均为165-240℃，经过熔体箱过滤后通过计量泵输送至模头及喷丝板喷出，喷丝板喷出的丝经过超纯水在线水柱极水幕后吸附到成网上成型，最后经过80-110℃的烘箱烘干后收卷，即得到熔喷过滤材料。
其中挤出机一区温度为165-175℃、二区温度为180-190℃、三区温度为195-215℃、四区温度为220-225℃、五区温度为225-230℃、六区温度为230-235℃、七区温度为235-240℃；经烘箱烘干后过一道热风去除水汽，最后收卷，如缺少除湿会造成收卷后的布料内有水汽。
熔体箱内过滤过程中的过滤网精度为300-500目。
本发明所得到的一种熔喷过滤材料及其制备方法，能有效增加材料的硬挺度，同时保证其韧性，不易断裂，使其具有玻纤或者复合材料的使用性能。
本发明所得到的熔喷过滤材料，其相对于玻纤相同过滤效率的条件下具有更低的过滤阻力，达到高效低阻的高标准过滤性能。
