摘要

A new kinds of waterborne polyurethane acrylate (WPUA) dispersions were synthesized based on isophorone diisocyanate (IPDI), hydroxyl-terminated polybutadiene (HTPB), 1, 4-butanediol (1, 4-BDO), polytetramethylene ether glycol (PTMG), dimethylolpropionic acid (DMPA), 2-ethylhexyl acrylate (EHA), and methyl methacrylate (MMA) as main raw materials. The influence of the HTPB content on the particle size, storage stability of the WPUA dispersions and the damping property of cured films were studied by using dynamic light scattering (DLS), dynamic mechanical analysis (DMA), respectively. It can be found the WPUA dispersions have a good stability and the damping temperature range of loss tangent (tan delta) >0.3 reaches a maximum (-26.6-79.14 degrees C) when the content of HTPB is 20%. The HTPB based WPUA could be applied to damping material.
