长链脂肪酸钠/芳基酰胺脂肪酸钠复配成核剂对聚丙烯性能影响研究
Effect of long chain fatty acid sodium/sodium arylamide fatty acid compounding nucleating agent on properties of polypropylene
摘要
Abstract
The sodium salt of long chain fatty acid and sodium of arylamide fatty acid were compounded to form a com-pounding nucleating agent(SCAB),and its effect on the crystallization and mechanical properties of polypropylene(PP)was investigated.The results indicated that the molecular structure of SCAB was not changed during its compounding process or at the processing temperature of PP,and its intermolecular aggregation state was significantly improved by the compounding process.The nucleated PP showed a significant increase in the crystallization rate,notch impact strength,and tensile strength with the extension of the carbon chain length of sodium salt of long chain fatty acid.The compound-ing did not affect the crystal growth mode of PP.Owing to the excellent dispersibility of SCAB in the PP matrix,a com-bination of SCAB with sodium stearate could refine the PP spherulites effectively and improve its crystal structure.This resulted in an increase in the crystallization rate of PP by 6.3 times,in the notch impact strength by 27.3%,and in the tensile strength by 8.2 MPa.关键词
