ACRYLIC EMULSION PRESSURE SENSITIVE ADHESIVE COMPOSITION COMPRISING NANO-SIZED LATEX OF MONOMODAL PARTICLE SIZE DISTRIBUTION AND MANUFACTURING PROCESS THEREOF

摘要

The present invention relates to an acrylic emulsion adhesive composition including latex particles of monomodal particle size distribution, in which polymer microparticles including (A) (meth)acrylic acid ester monomers having a C1-C14 alkyl group as a main monomer; (B) at least one monomer selected from the group consisting of a monomer containing allyl ester, vinyl ester, an unsaturated ester group, or a mixture thereof, and a cyano group, a monomer including an amine group and a styrene-based monomer having a vinyl group as an auxiliary monomer; (C) a monomer having a carboxyl group and/or a hydroxyl group as a functional monomer; and (D) a crosslinking agent, are surrounded by at least three kinds of anionic emulsifiers, and a manufacturing method thereof. The latex particles are characterized by high solid powder with a nanosized average particle diameter and a monomodal particle size distribution, and high stability.
