Description

一种PP透气膜及其制备工艺
技术领域
本发明属于流延膜生产技术领域，特别涉及一种PP透气膜及其制备工艺。
背景技术
对于现在建筑，大多数墙体都是采用细石混凝土或者给墙体涂抹防水材料。这样就存在以下几点不足：墙体的热对流加快，不利于建筑保温，造成能源损失；外界雨水和水蒸气对墙体建筑造成侵蚀和霉变。
针对上述现象，专利CN 103978653 A公开了一种PP防水透气膜加工工艺，按质量份数将4份聚丙烯，5份碳酸钙粉料，0.5份偶联剂混合在挤出机中加热至230-260℃、混炼、挤出后冷却定型成厚度为60微米的薄膜，再将定型的膜单向拉伸3倍长度。通过聚丙烯与碳酸钙粉料混合，通过偶联剂的作用使其混合制成薄膜，在制成薄膜后通过单向拉伸使得聚丙烯材料拉伸，由于碳酸钙粉没有延伸性能，在拉伸之后薄膜表面会形成微孔，这种微孔的孔径一般在纳米级别，仅仅水蒸气分子可通过，液态的水分子无法通过，能够实现卓越的防水透气性；但通过该加工工艺加工出的PP防水透气膜仍存在一定的缺点：配方中聚丙烯的加入量相对较少，且最终制造出的防水透气膜硬度比较硬，不易和无纺布复合。
发明内容
本发明要解决的技术问题是提供一种易与无纺布复合的PP透气膜及其制备工艺。
为解决上述技术问题，本发明的技术方案为：一种PP透气膜，其创新点在于：所述PP透气膜是由以下重量份的组分组成，总计100重量份：聚丙烯树脂14-16份、碳酸钙50-52份、茂金属5815 14-16份、线性聚乙烯树脂14-16份和高密度聚乙烯3-5份。
进一步地，所述聚丙烯树脂选用融指为10-15的聚丙烯树脂。
进一步地，所述碳酸钙选用粒径≥4000目的碳酸钙粉。
进一步地，所述线性聚乙烯树脂选用融指为2的线性聚乙烯树脂。
进一步地，所述高密度聚乙烯选用融指为8的高密度聚乙烯。
一种上述的PP透气膜的制备工艺，其创新点在于：所述制备工艺包括如下步骤：
（1）按质量份数将14-16份聚丙烯树脂、50-52份碳酸钙、14-16份茂金属5815、14-16份线性聚乙烯树脂和3-5份高密度聚乙烯混合蜜炼制成透气树脂，然后加入透气膜挤出机中；在挤出机中，将螺杆加温至240℃、融化、挤出后冷却定型厚度为0.2-0.6mm的薄膜；
（2）将步骤（1）冷却定型厚度为0.5mm的薄膜一次预热至80-90℃，然后将一次预热的薄膜单向拉伸1.2-1.4倍长度，再二次预热至80-90℃，然后将二次预热的薄膜单向拉伸1.3-1.4倍长度，最后三次预热至80-90℃，然后将三次预热的薄膜单向拉伸1.4-1.5倍长度，冷却定型，形成PP透气膜。
本发明的优点在于：本发明PP透气膜，其中，高密度聚乙烯，是一种结晶度高、非极性的热塑性树脂，耐酸碱，耐有机溶剂，电绝缘性优良，低温时，仍能保持一定的韧性；表面硬度，拉伸强度，刚性等机械强度都高于LDPE，接近于PP，比PP韧，因而可有效降低PP透气膜的硬度；碳酸钙作为PP透气膜的填料，由于碳酸钙粉体是亲水性无机化合物，其表面有亲水性的羟基，呈现较强的碱性，这种亲水疏油的性质使得碳酸钙与有机高聚物的亲和性差，容易团聚，在高聚物内部分散不均匀，且随着填充量的增加，这些缺点更明显，因而碳酸钙的量控制在小于总组分量的55%；此外，由于碳酸钙颗粒粒径小，颗粒数量大，总表面积也大，需要更多的载体树脂对其包覆，因而在配方中加入了聚丙烯树脂和线性聚乙烯树脂；同时，配方中加入了茂金属5815，其无拉伸振动、出色的热封性能、抗撕裂强度、抗冲击强度、抗穿刺及高流动性，进而使得PP透气膜易与无纺布进行复合，且提高了复合材料的静水压和拉力。
具体实施方式
