AQUEOUS POLYURETHANE RESIN DISPERSION, MANUFACTURING METHOD FOR SAME, AND PAINT COMPOSITION CONTAINING SAME |
摘要 |
It is to provide an aqueous polyurethane dispersion which gives a coating film excellent in abrasion resistance. It is an aqueous polyurethane resin dispersion which comprises a polyurethane resin obtained by reacting (A) a polyurethane prepolymer which is obtained by reacting (a) a polyisocyanate compound, (b) a polyol compound containing a polycarbonate polyol having an alicyclic structure, and (c) a polyol compound having an acidic group, and (B) a chain elongating agent having a reactivity with the isocyanate group of (A) the polyurethane prepolymer, being dispersed in an aqueous medium, a content of an alicyclic structure is 26.0 to 60.0% by weight in terms of a solid component(s), and a sum of a content of an urethane boding and a content of a urea bonding is 17.7 to 30.0% by weight in terms of a solid component(s). |
