The waterborne polyurethane-acrylate hybrid emulsions modified by methyl methacrylate (MMA) and butyl acrylate (BA) copolymer were synthesized by using 1
4-butanediol (BDO)
dimethylopropionic (DMPA) and adipic dihyrazide (ADH) as chain extenders.The effects of the amounts of BA and diacetone acrylamide (DAAM) on the properties of hybrid emulsions
films and adhesive were studied.The structure of the hybrid emulsions was characterized with Fourier transform infrared (FTIR).The experiment results showed that when the amount of BA was 4.0%—6.0%
that of DAAM was 2.0%—3.0%
the properties of the hybrid emulsion
films and adhesive were satisfactory.The adhesive which was made by polyurethane-acrylate hybrid emulsion with a better adhesive for wood.
