In this paper

a blending modification method is used to obtain a nylon 6 matrix with high melt strength. Through exploring different process conditions

nylon 6 foam materials with different magnifications are obtained

and the melt strength of different ionomer modifier ratios is systematically studied. Influence. The existence of micro-crosslinked structure is inferred through thermal performance test and rheological test. Nylon 6 foam materials with different foaming ratios were prepared by adjusting the foaming process

and the cell morphology was observed with a scanning electron microscope (SEM). The results show that the addition of ionomer greatly improves the melt strength of the nylon 6 matrix

realizes the possibility of nylon 6 supercritical carbon dioxide foaming

and obtains a nylon foam material with a larger magnification.
