Abstract:
The title polyurethane-polyacrylate emulsion with interpenetrating polymer network(IPN )structure was prepared by emulsion polymerization method. By means of DSC and rheometer, the microphase separation and damping properties were studied, and the prepared polymer was used in high-speed rail vehicle damping coatings, providing high damping performance in a wide range of temperature and meeting the practical needs of high-speed rail venicle.
