Abstract |
Abstract Simplification of the manufacturing process in shoe making is essential to improve
productivity and reduce production costs. To improve the adhesion of EVA foam
used as a midsole, EVA/itaconated EPDM(EPDM-g-IA)(80/20wt%) blend was prepared
using Torque Rheometer-Plasti-Corder, and 1,6-hexamethylenediamine/crosslinking
agent/foaming agent/additive were mixed, followed by amidation reaction and foaming
to prepare EVA/EPDM-g-IA foam for shoe midsole. In this study, we investigate the effect
of the content of 1,6-hexamethylenediamine(0, 0.5, 1.0, 2.0, 3.0) on the mechanical
properties, water-contact angle and adhesion of EVA/itaconated EPDM foam. As the content
of 1,6-hexamethylenediamine increased, mechanical properties such as tensile
strength, tear strength, tensile elastic modulus, hardness, and water-contact angle were
lowered, but elongation at break and compression set(%) were increased. Both normal
type and non-UV type adhesive strength increased with increasing diamine content. In
particular, it was found that the adhesion strength of the non-UV type adhesion increased
sharply with increasing diamine content. As a result, an adherend rupture occurs in a
foam sample having a content of 1,6-hexamethylenediamine of 3phr. From this, it can
be seen that the EVA/itaconated EPDM foam for shoe midsoles, which can be used for
non-UV adhesion without primer and UV treatments, have been developed. |
