Polyethylene-based moisture absorbing composite material and preparation thereof

聚乙烯基吸湿功能复合材料及其制备方法

Abstract

本发明公开了一种聚乙烯基吸湿功能复合材料及其制备方法,该材料的组分及其重量百分比含量为:低密度聚乙烯60~80%,相容剂2~8%,聚乙烯醇10~30%,助剂5~10%。它是通过聚乙烯醇首先与助剂熔融复合制得预混物,然后与低密度聚乙烯、相容剂在双螺杆挤出机上熔融共混,制得聚乙烯基吸湿功能复合材料。本发明所采用的复合方法具有简便、环保、成本低廉、易于工业化生产等优点;制得聚乙烯基吸湿功能复合材料,具有吸湿功能,可用于制备薄膜,并使薄膜具有较好的吸湿功能,同时保持良好的力学性能。
The invention discloses a polyvinyl composite material with moisture absorption function and a method for preparing the same. The compositions by weight percentage of the material are: 60 to 80 percent of low density polyethylene, 2 to 8 percent of compatilizer, 10 to 30 percent of polyvinyl alcohol and 5 to 10 percent of auxiliary agent. The method is as follows: firstly, premixture is prepared through fusion and composition of the polyvinyl alcohol and the auxiliary agent; secondly, the premixture is fused and mixed with the low density polyethylene and the compatilizer on a double-screw extruder, and the polyvinyl composite material with the moisture absorption function is prepared. The composite method adopted by the invention has the advantages of simplicity, convenience, environmental protection, low cost, easy industrialized production and so on; the prepared polyvinyl composite material with the moisture absorption function has the moisture absorption function and can be used for preparing a film; and the film has good moisture absorption function and simultaneously maintains good mechanical property.
