Core / shell microgel containing alkylene monoisocyanate / poly (ethylene oxide) monoalcohol monomer and coating composition containing same

摘要

The present invention relates to a core / shell-type microgel containing an alkylene monoisocyanate / poly (ethylene oxide) monoalcohol adduct and to a coating composition containing the same, and more particularly to alkylene monoisocyanate and poly (ethylene oxide) mono A method of preparing a core / shell-type microgel in which a reactive emulsifier obtained by alcohol-containing urethane bonds in an equivalent ratio of 1: 1 is improved in a shell composition and 5 to 100 weight of the microgel as a binder in paint. It is directed to a waterborne coating composition comprising a blend using% and main resin 0-95% by weight and pigments and other paint additives and having a total solids content of at least 15% when applied.;Sub-based coating composition prepared according to the present invention shows excellent water resistance, fouling resistance and adhesion even at relatively low baking conditions and solid content of 15% or more, and can be blended with other urethane resins or urethane copolymers for automotive use. It can be usefully used for refinish paint, plastic paint, and building paint.
