Acrylic polymer bead, preparation method and crylic polymer bead and acrylic sol composition with improved storage stability and coating property for automobile

摘要

The invention, including parts such as underbody floor, wheel housing, fuel tank of the vehicle, the vehicle body panel joint portion and the hood, the acrylic polymer used in the acrylic sol which the door or the like used as a water-tight, dust-proof and anti-corrosive purposes beads and this relates to an acrylic sol composition, specifically forming the seed using any of the core layer configuration monomers by using a seed polymerization comprises a cross-linking agent suitable amount and then by polymerizing a monomer of the residual amount to form a core layer, containing a crosslinking agent suitable amount when the acrylic polymer beads of the present invention having a core / shell structure in which form the shell layer in order that is used together with a plasticizer and a filler to the acrylic sol for automobiles which the size distribution of particles narrow produced on the storage stability of the acrylic sol and gelling it is excellent in physical properties of the coating film.
