负载庚二酸钙硅灰石填充聚丙烯的β－成核作用研究
β-Nucleating effect of calcium pimelate-supported wollastonite filled polypropylene
摘要
Abstract
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 POMindicated that calcium pimelate formed on the surface of wollastonite,re-sulting in α→βtransition 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 wollaston-ite /pimelic acid.关键词
