Abstract

The acrylate emulsion with carboxyl group is prepared through a semi-continuous and pre-emulsification polymerization process. In corporation of crosslinking agent zinc acetate will lead the chelation crosslinking between carboxylicion and metalion. The effect of different n ( Zn2+ ):n (-COOH ) and carboxyl group content on the property of emulsion is discussed. A self-crosslinking emulsion is prepared, which shows its pencil hardness 2H and water resistance over 96 h.

Key words： self-crosslinking; acrylate emulsion; hardness; water resistance; chelation crosslinking
