纳米聚丙烯材料的研制

Production of Nano PP Materials

研究无机纳米碳酸钙表面处理复合技术,通过对纳米碳酸钙的包覆,解决了纳米材料的团聚问题,以此制备出一种高性能、高流动、高耐温、使用范围更广泛的聚丙烯复合材料。结果表明,均聚聚丙烯:20 000目碳酸钙的EPDM比例为78:20:2的复合材料的性能最佳,其值为MFR值为13.210 g.(10 min)^(-1),拉伸强度为27.08 MPa,弯曲强度为37.03 MPa,冲击强度为2.85 ft-lb/in。

Surface treatment composite technology of the inorganic nano calcium carbonate was studied. By coated with the nano calcium carbonate, the problem of agglomeration of nano materials was solved, and a kind of high performance, high flow, high temperature resistance, a wider use range of polypropylene composites were prepared. The results show that all polypropylene：calcium carbonate（20000 mesh）： EPDM ratio of 78：20：2 composite material performance is best, whcih value of MFR value is 13.210 g.（10 min）-1, the tensile strength is 27.08 MPa, flexural strength is 37.03 MPa and impact strength is 2.85 ft-lb/in.
