摘要

A hybrid synthesis technology was used to prepare waterborne polyurethane/acrylic hybrid emulsions by polymerization of methyl methacrylate, butyl acrylate, 2-ethylhexyl acrylate(EHA), and N-acryloylmorpholine (AMCO) in presence of acrylicterminated PU dispersion. Various characterization methods were used to investigate the effect of EHA and ACMO content on the properties of the hybrid emulsions and their resultant films. The research results show that the introduction of EHA can enhance the elasticity of their films, meanwhile, ACMO endows the film with high gloss, adhesion on substrate, toughness, and hardness. Mixing the two monomers leads to yield the hybrid materials with moderate properties. While increasing the weight ratio of ACMO/EHA, the average particle size of the hybrid emulsions increases and their viscosity decreases. For the resultant films, their surface water contact angle, adhesion on substrates, tensile strength, and hardness increase, but the water resistance and elasticity decrease. It has been found that EHA and ACMO have a synergistic effect on gloss of the hybrid films and the hydrogen bond interaction increases with an increase in the ACMO content.
