Description

一种颜色均匀且熔接性能高的发泡聚丙烯珠粒的制备方法
技术领域
本发明涉及聚丙烯发泡珠粒的制备方法，具体为一种颜色均匀且熔接性能高的发泡聚丙烯珠粒的制备方法。
背景技术
发泡聚丙烯珠粒，因其优异的机械强度、耐热性能、机械加工性、耐燃性和可再生利用性而广泛应用于各种不同领域。例如，汽车内饰件，包装材料、建筑材料，隔热材料等。特别是在汽车等运输工具等领域中，发泡聚丙烯珠粒已经用于各种零部件，例如保险杠，遮阳板，工具箱，座椅等。
随着发泡聚丙烯应用面的拓宽，各行业对材料的综合性能要求越来越高，其中制件的外观首当其冲。仅以黑色的发泡聚丙烯珠粒微粒，现有市场的产品存在两个方面的问题：
1、为了满足发泡品的黑度，其色母的添加量达到20％左右，为塑料件中色母用量的10倍，如此大的添加量一方面大大降低了发泡聚丙烯珠粒的力学性能，另一方面使得发泡聚丙烯珠粒的成本居高不下。
2、受色母粒度的限制，炭黑在树脂中极易发生二次团聚，导致炭黑在聚丙烯树脂中的分散性能很差，使得发泡的珠粒存在大量的颜色发灰的粒子，严重影响制品的外观，色粉的分散不均匀，易出现断丝、细丝的现象；所以如何提高发泡聚丙烯珠粒颜色均匀分散也具有较高的意义。
发明内容
本发明要解决的技术问题是克服现有的缺陷，提供一种高刚性聚丙烯发泡珠粒及其节能制备方法。
为了解决上述技术问题，本发明提供了如下的技术方案：
一种颜色均匀且熔接性能高的发泡聚丙烯珠粒，其配方包括如下各组份：聚丙烯树脂、改性色母、分散添加剂，其中，分散添加剂的添加量占体系总重量的 0.1％～2％；改性色母的添加量为体系总重量的6～8％，所述改性色母为粒径为15～18nm纳米级的炭黑。
进一步的，所述的聚丙烯树脂的MFR为7～15g/10min。
优选的，所述聚丙烯树脂为均聚聚丙烯、二元共聚聚丙烯及三元共聚聚丙烯中的任一种，优选二元共聚聚丙烯，其共聚单元包括乙烯单体、丁烯单体，最优的为乙烯单体作为共聚单体。
进一步的，所述的分散添加剂为聚乙烯蜡、聚丙烯蜡、EVA蜡、硬脂酸锌、硬脂酸钙、芥酸酰胺、石蜡、脂肪酸及脂肪酸脂类的任一种或几种；其中以EVA蜡和芥酸酰胺的效果最佳。
一种颜色均匀且熔接性能高的发泡聚丙烯珠粒的制备方法，包括以下几个步骤：
1)将聚丙烯树脂、改性色母、分散添加剂混匀；经挤出机混炼、挤出、拉丝、切粒制备成聚丙烯微粒；
2)将上述聚丙烯微粒投入反应釜，然后进行加热加压，使聚丙烯微粒在高温高压下产生向外膨胀的内部压力，并在瞬间释放至大气，从而得到一定倍率的具有颜色均匀且熔接性能优异的聚丙烯发泡珠粒；
进一步的，所述步骤2)中的加压气体为氮气、氧气、二氧化碳、空气中一种或者多种。
本发明的发泡聚丙烯珠粒配方，对各组分重量进行调控，其色母用量仅为普通配方的70％-80％，可明显解决粒子中“白粒子”及“灰粒子”的量，使得发泡聚丙烯珠粒的整体颜色均一性较好，粒径大小均一；另一方面该发泡聚丙烯珠粒在成型时所采用的蒸汽压力较低，成型蒸汽压力降低20％，使用该发泡聚丙烯珠粒制得的制件的熔接性提高，力学性能也有改善(50g/L的EPP产品50％压缩强度由394KPa增加到413Kpa以上；拉伸强度由613KPa增加到635KPa以上)。

图2是实施例3所得的高颜色分散性及高熔接性能的聚丙烯发泡珠粒的热值(DSC)分析曲线；

具体实施方式
以下对本发明的优选实施例进行说明，应当理解，此处所描述的优选实施例仅用于说明和解释本发明，并不用于限定本发明。
实施例
以黑色产品为例，以未添加分散助剂的发泡聚丙烯珠粒为对照，制得的发泡聚丙烯珠粒的参数如下：
实施例1-5的发泡改性聚丙烯材料的体积为15～25cm3/g，泡孔结构为闭孔结构，并且泡孔密度高而均匀。该发泡聚丙烯材料在差式扫描量热仪上测量其热晗值时显示2个吸热峰，测量方法如下：将轻质颗粒样品在氮气中以10℃/分钟的速率从室温(10～40℃)加热到180℃。然后，把该样品冷却到60℃低温，再次通过在以10℃/分钟的速率加热到180℃进行热晗值曲线测定，绘得到如图2所示的热晗值分析曲线。其中第一升温曲线会产生2个吸热峰，第1个吸热峰的顶点在两种聚丙烯材料熔点分界点的左边-20℃～0℃之间，第2个吸热峰的顶点在两种聚丙烯材料熔点分界点的右边0℃～20℃之间，为发泡聚丙烯的特征吸收峰，当第二次升温时此吸收峰消失。
图1是实施例3所得的高颜色分散性及高熔接性能的聚丙烯发泡珠粒扫描电镜照片(EPP珠粒断面的扫描电镜照片)，说明添加分散剂芥酸酰胺制备的EPP珠粒的泡孔密度高、大小均匀、独立且闭孔率高。
图2是实施例3所得的高颜色分散性及高熔接性能的聚丙烯发泡珠粒的热值(DSC)分析曲线，说明添加分散剂芥酸酰胺制备的EPP珠粒相对不加分散剂的情况下，成型压力降低明显(2.2-2.7bar)，熔接良好。
图3是实施例4所得的高颜色分散性及高熔接性能的聚丙烯发泡珠粒的热值(DSC)分析曲线，说明添加分散剂硬脂酸锌制备的EPP珠粒，具有较低的成型压力(2.4-2.9bar)和高熔接性能。
图4是实施例5所得的高颜色分散性及高熔接性能的聚丙烯发泡珠粒的热值(DSC)分析曲线，说明添加分散剂PE蜡制备的EPP珠粒，具有较低的发泡温度(152.6℃)，在较高热值(29.4J/g)的情况下，成型压力依然降低明显(2.2-2.6bar)，熔接性能优异。
最后应说明的是：以上所述仅为本发明的优选实施例而已，并不用于限制本发明，尽管参照前述实施例对本发明进行了详细的说明，对于本领域的技术人员来说，其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
