The study on the crosslinking technology of acrylic resin
Abstract: Based on the three kinds of water-based acrylic resin:Ketone hydrazine crosslinking waterborne acrylic resin,Epoxy acrylate resin modified waterborne,N-methylol acrylamide crosslinked aqueous acrylic ester resin prepared, characterization and performance analysis,focuses on the types of crosslinking an aqueous resin, the reaction mechanism and the actual results.Measured under different conditions after the film three resins water absorption rate of alcohol absorption and infrared spectroscopy and DMA for these films were analyzed.Research shows that one hydrazine crosslinking is an effective cross-linking and cross-linking composite technology;Epoxy-modified waterborne acrylate resin and N - methylol acrylamide modified aqueous acrylate resins cured at 120 ℃ maximum degree of crosslinking.
