블릿 Abstract(Eng)
In this study, research was conducted into the manufacture of thermally expandable microspheres for automotive underbody coatings and applications in industry. In particular, the relationship between heat resistance and the ratio of crosslinking agents and initiators in the manufacture of the thermally expandable microspheres was investigated. We focused on the results with various cross-linking agents; our aim was to make the walls of the microspheres thicker to solve the problem of reductions in size caused by shrinkage when the microspheres are heated to T m (T max). We observed the sectional thickness and surface of the samples with thicker walls. The thick thermally expandable microspheres showed reduced shrinkage and excellent stability in spite of prolonged exposure to heat.
