Synthesis and Properties of Acrylate Modified Waterborne Polyurethane Emulsion

Abstract:

Acrylate modified waterborne polyurethane (PUA) emulsion was prepared by means of core-shell polymerization processes. The structures and properties of emulsions were characterized by FTIR, TEM and DSC. The effects of polymerization temperature, the type and amount of initiator and the acrylic amount on the properties of emulsions were investigated. The experimental results showed that the emulsions prepared were core-shell composite, when the polymerization temperature was 70~75 °C, using oil-soluble initiator azobisisobutyronitrile (AIBN), and the percentage of AIBN was 2.0%~ 2.5%, the properties of the emulsion can be better, and the water resistance, stability and mechanical properties of the PUA films were improved increasingly.
