Description

PE类抗老化功能母粒及其制备方法
技术领域
[0001 ]本发明涉及一种抗老化功能母粒,尤其涉及一种PE类抗老化功能母粒及其制备方法。
背景技术
[0002]塑料受到外界的阳光、氧气、湿热等容易引起老化,塑料老化会使塑料丧失使用价值,产生巨大的经济损失。现有的抗老化功能材料的生产方式有以下三种:
[0003] 1、树脂中添加抗紫外光剂后直接加工,此方式容易导致抗紫外光剂在产品中分散不均匀而导致产品出现异常,抗紫外光剂多的地方材料抗老化性强,抗紫外光剂较少的地方材料较易老化。
[0004] 2、树脂添加抗紫外光剂后经单螺杆挤出机或双螺杆挤出机挤出切粒后再加工出成品,此方式效果好,但成本高,由于经过单螺杆挤出机或双螺杆挤出机挤时需要对树脂进行高温作业才能加工,新料变成了二次料,故对树脂的性能会有影响。
[0005] 3、现有的抗老化功能母粒制备过程中,树脂中加入大量的抗紫外光剂容易造成加工时双螺杆挤出机的螺杆不吃料,断条不能切粒,导致机器无法正常运行,因此无法制备抗紫外光剂含量高的抗老化功能母粒。通常需要按每100份树脂中添加8〜12份该抗老化功能母粒才能达到很好的抗老化效果。
发明内容
[0006]发明目的:针对上述问题,本发明的目的是制备一种抗紫外光剂含量高的抗老化功能母粒,降低其在树脂中的加入量但是能达到现有的抗老化效果,且不影响树脂的性能。
[0007]技术方案:
[0008] —种PE类抗老化功能母粒,以总质量100份计,由以下质量份的原料组成:25〜75份PE类树脂、15〜25份抗紫外光剂、O〜20份抗氧剂、O〜50份填充粉。
[0009] 所述PE类树脂为LLDPE、PE、EVA中的一种,选用熔体流动速率为20〜50g/10min的PE类树脂。
[0010] 所述抗紫外光剂为群531、群944、群5411中的一种。
[0011 ]所述抗氧剂为抗氧剂1010、抗氧剂168中的一种。
[0012]所述填充粉为碳酸钙、滑石粉、硫酸钡、硅灰石、白炭黑中的一种。
[0013] 一种PE类抗老化功能母粒的制备方法,包括如下步骤:
[0014]步骤1:按组成原料的配比称取PE类树脂、抗紫外光剂、抗氧剂及填充粉,在高低速混料机中混合均匀;
[0015]步骤2:将混合好的原料加至单螺杆挤出机或双螺杆挤出机中挤出后切粒;
[0016]步骤3:根据切粒后的功能母粒含水量选择自然冷却蒸发或低温烘干。
[0017] 其中,步骤I中,在所述高低速混料机中混合3〜5min,混合速度为400〜500r/min。
[0018]其中,步骤2中,单螺杆挤出机或双螺杆挤出机的加热温度为100〜160°C。
[0019]其中,步骤3中,如功能母粒含水量低则选择自然冷却蒸发,如功能母粒含水量较高则选择低温烘干,烘干温度为30〜60°C,过高的烘干温度会使此功能母粒变软结块。
[0020]有益效果:与现有技术相比,本发明的优点是制备的抗老化功能母粒的抗紫外光剂含量高,使用时添加量少,仅需按每100份树脂中添加2〜4份该母粒就能达到与现有产品等同的抗老化效果,且添加后不影响树脂的性能。虽然制备的抗老化功能母粒中抗紫外光剂含量高,但是通过本发明制备方法,克服了螺杆挤出时不吃料、断条不能切粒的问题,色母厂现有的设备即可持续大批量生产,加工过程中无粉尘、加工性好、分散性好、能耗低,还可在配方中加入有色颜料,使制得的母粒既能满足添加颜色的要求,还能达到抗老化的要求。
