Description

一种聚乙烯膜用防雾滴母粒
技术领域
本发明涉及高分子材料技术领域，具体地说是一种聚乙烯膜用防雾滴母粒。
背景技术
生产农用棚膜的原料主要是聚乙烯，棚膜多在我国北方的冬、春季使用。因为气候寒冷，大棚内外温度、湿度相差都较大，导致棚膜内壁上附有大量的雾滴。雾滴的危害：使光线发生折射，使薄膜的透光性大为降低；光线经水滴聚焦后折射到作物上，会将作物灼伤；细小的水滴会逐渐聚集变大，达到一定质量后会滴落至作物的花、茎、叶或果实上，使其枯烂，降低了作物的产量和质量；雾滴滴落时极易传播病菌，使棚室内的湿度增加，加之适宜的温度给许多病害的发生创造了合适的环境；棚内温度将随着雾珠蒸发而降低，减弱了大棚的保温效果。因此，消除雾滴的危害迫在眉睫，开发农用无滴膜有着极其重要的意义。
发明内容
本发明的目的在于提供一种防雾滴效果好、持久和使用方便的聚乙烯膜用防雾滴母粒。
本发明解决其技术问题所采用的技术方案是：一种聚乙烯膜用防雾滴母粒，其组分按质量百分数配比为：聚乙烯树脂50%～70%、流滴剂10%～20%、消雾剂10%～20%、稳定剂1%～3%、偶联剂0.5%～3%、分散剂1%～3%、抗氧剂0.1%～1%。
所述的流滴剂为聚氧乙烯山梨糖醇酐单月桂酸酯、聚氧乙烯山梨醇酐单硬脂酸酯、聚氧乙烯山梨醇酐单油酸脂、椰子油酸二乙醇酰胺中的一种。
所述的消雾剂为全氟烷醇不饱和酸酯聚合物、全氟烷醇与环氧乙烷的加成物、全氟烷醇酰胺中的一种。
所述的稳定剂为受阻胺光稳定剂。
所述的偶联剂为硅烷偶联剂。
所述的分散剂为低分子聚乙烯蜡。
所述的抗氧剂为受阻酚抗氧剂1010与亚磷酸酯类抗氧剂168的复配物。
上述的一种聚乙烯膜用防雾滴母粒的制备方法，包括以下步骤：按重量配比将各组分加入转速在1500转/分钟以上的高速混合机中充分混合15～30分钟，然后将混合好的物料加入双螺杆挤出机充分熔融共混，熔融温度控制在160℃～200℃，螺杆转速为100～600转/分钟，通过双螺杆挤出机的剪切、混炼10～15分钟，然后挤出、冷却、造粒、干燥、包装即得本发明的一种聚乙烯膜用防雾滴母粒。
本发明的有益效果是，与现有技术相比，本发明制得的一种聚乙烯膜用防雾滴母粒，具有良好的防雾滴、防老化、耐热性和耐化学性等，可以在生产聚乙烯膜中直接加入使用，其工序简单，操作方便，而且还能提升产品质量等，具有很好的实用价值和应用前景。
