摘要

This study quantified how the degree of cloisite? 20A nanoclay was dispersed in polypropylene matrix with maleic grafted anhydride polypropylene (MAPP) and how it influenced the morphology, mechanical, and thermal properties using melt intercalation processing method. The polypropylene nanocomposites (PPNCs) were prepared with different ratios (100/0/0, 95/4/1, 93/4/3, 91/4/5, 89/4/7 and 86/4/10) of the polypropylene (PP), maleic grafted anhydride polypropylene (MAPP) used as compatibilizer and cloisite? 20A (C20A), with the same processing conditions. The characterization results revealed that X-ray diffraction (XRD) analysis revealed that intercalated structures in SEM were formed with the addition of nanofiller and compatibilizer to PP matrix. PPNC with 10wt % of clay offered the lowest thermal conductivity (k) value of 0.1230W/Mk, and showed poor mechanical properties in strength, and stiffness due to high clay content in the composite. The tensile strength was improved and tensile modulus enhanced. Tensile strength and modulus were maximal for PPCN with 3wt% C20A at 44.29 (±2.26) MPa and 1.4818 (±0.428) respectively, and thermal conductivity of 0.2198 W/Mk. Hence, PPNC 3% is recommendable for thermal insulation application.
機(jī)譯：這項(xiàng)研究量化了梭母石的程度 ? 將20A納米粘土與馬來酸酐接枝的聚丙烯（MAPP）一起分散在聚丙烯基質(zhì)中，并通過熔體插層加工方法影響其對形態(tài)，機(jī)械和熱性能的影響。制備具有不同比例的聚丙烯納米復(fù)合材料（PPNC）（100/0 / 0、95 / 4 / 1、93 / 4 / 3、91 / 4 / 5、89 / 4/7和86/4/10）。聚丙烯（PP），馬來接枝酸酐聚丙烯（MAPP）用作增容劑和絲石 ? 20A（C20A），具有相同的加工條件。表征結(jié)果表明，X射線衍射（XRD）分析表明，在PP基質(zhì)中添加了納米填料和增容劑，從而在SEM中形成了插層結(jié)構(gòu)。粘土含量為10wt％的PPNC的最低導(dǎo)熱系數(shù)（k）值為0.1230W / Mk，并且由于復(fù)合材料中的粘土含量較高，因此在強(qiáng)度和剛度方面均顯示出較差的機(jī)械性能。拉伸強(qiáng)度得到改善，拉伸模量得到提高。具有3wt％C20A的PPCN的拉伸強(qiáng)度和模量分別最大，分別為44.29（±2.26）MPa和1.4818（±0.428），導(dǎo)熱系數(shù)為0.2198 W / Mk。因此，建議將PPNC 3％用于隔熱應(yīng)用。
