中文摘要：
为获得硅灰石填充β-聚丙烯（β-PP）复合材料,该文采用硅灰石与庚二酸反应制备负载庚二酸钙的硅灰石（β-W）,并对比研究硅灰石和β-W对聚丙烯（PP）结晶具有的异相成核作用。FTIR和TGA结果证实β-W表面庚二酸钙的形成。DSC、XRD和POM结果表明硅灰石表面形成的庚二酸钙导致硅灰石表面成核机理的α→β转变。β-W填充PP复合材料主要形成β-晶,β-W具有的β-成核作用与硅灰石/庚二酸质量比有关。
英文摘要：
In order to obtain wollastonite filled β-polypropylene composites,calcium pimelate-supported wollastonite（ β-W） was prepared through the chemical reaction between wollastonite and pimelic acid,and the heterogeneous nucleating effect of wollastonite and β-W on PP crystallization was investigated.FTIR and TGA analyses confirmed the formation of calcium pimelate on the surface of wollastonite. The results of DSC,XRD and POM indicated that calcium pimelate formed on the surface of wollastonite,resulting in α→β transition of nucleation mechanism of wollastonite surface. The β-W filled PP composites mainly formed β-phase,and the β-nucleating ability of β-W was dependent of the mass ratio of wollastonite / pimelic acid.
