Preparation and Research of Acrylate Latex

摘要

With the development of economy, people pay more and more attention to environmental protection. The proportion of water-based ink in the ink industry is increasing due to its good environmental friendliness. Water-based acrylate latex has been widely used in water-based inks due to its good film formation, printing adaptability, light resistance, and corrosion resistance. In this paper, a series of acrylate latexes were prepared by non-pre-emulsification semi-continuous emulsion polymerization by compounding small-molecule emulsifiers (LS: SDS & OP-10) with macromolecular emulsi-fiers (acrylic resins). And the effect of additive amounts of small molecule emulsifier and macromolecular emulsifier on the properties of acrylate latex was investigated. When the additive amount of the small molecule emulsifier was 1.5 wt% and the macromolecular emulsifier was 30 wt%, the acrylate latex with a small particle size, moderate viscosity, and good stability could be prepared.
