Water-based emulsion for vibration damper

摘要

A water-based emulsion for vibration damper is provided for the formation of an excellent vibration damper. In an aspect, the emulsion for vibration damper contains a particle including a core part formed of an acrylic copolymer (A) and a shell part formed of an acrylic copolymer (B) which covers the core part, the glass transition point of the acrylic copolymer (B) being not lower than -9°C, and the difference between the glass transition point of the acrylic copolymer (B) and the glass transition point of the acrylic copolymer (A) being not less than 20°C.
