Abstract |
Waterborne polyurethane(WPU) is greatly affected by its properties depending
on the average particle size. In this study, by analyzing the characteristics of WPUs
with different average particle sizes according to the DMPA content and we confirmed
that the WPU-Ms have different properties from the physical properties of WPU by
mixing two types of WPU with different particle sizes in the same volume. At this
time, we mixed WPU at an ideal ratio of 7:3 through literature research. In the thermal
characteristic analysis, it was confirmed that the thermal decomposition temperature
decreased and Tg increased as the content of DMPA, which is the hard segment,
increased. In addition, the average particle size of WPU decreased as DMPA increased,
and physical properties and adhesive strength were improved due to increased
interaction. When mixed with each other in a weight ratio of 7:3, it was observed
that adhesion and mechanical properties were improved compared to only WPU. |
