摘 要:利用十八醇和環(huán)氧氯丙烷反應合成了十八烷基縮水甘油醚(OGE),并將其作為熔融共混方法中的增容劑,制備了尼龍6(PA6)/高密度聚乙烯(HDPE)共混材料。研究了OGE用量對共混物的熱性能、結晶行為、形態(tài)結構、力學(xué)性能及吸水性的影響。結果表明,OGE促進(jìn)了HDPE在PA6基體中的分散,在保持共混材料吸水率的同時(shí),有效改善了共混物的力學(xué)性能,與未加入增容劑的PA6/HDPE共混物相比,OGE含量為2.9%(m/m)時(shí),共混材料的缺口沖擊強度、拉伸模量、斷裂伸長(cháng)率、彎曲強度分別提高了12%、33%、95%、6%,拉伸強度基本保持不變,而彎曲模量下降了8%。 |

Abstract:Octadecyl glycidyl ether(OGE)was synthesized and used as a melt blending compatibilizer in the preparation of PA6/HDPE blends. Effects of the loading of OGE on the thermal properties,crystallization behavior,morphology,mechanical properties,and water absorption of the blends were studied. Experimental data indicated that OGE could accelerate the crystallization process of HDPE in the blends,enhance the dispersion of HDPE in the PA6 basis as well as the mechanical properties of the blends. Compared to PA6/HDPE blends without OGE,the notched impact strength,tensile modulus,elongation at break and flexural strength of PA6/HDPE blend increased by 12%,33%,95% and 6%,respectively,at a loading of 2.9%(m/m). The tensile strength of the PA6/HDPE blend remained unchanged,but the flexural modulus decreased by 8%. |
