Adipique dihydrazide, AcideL'acide dihydrazide adipique (ADH) est un produit chimique utilisé pour la réticulation à l'eau des émulsions . Il peut également être utilisé en tant que durcisseur pour certains résines époxydes. L'ADH est une molécule symétrique avec un squelette C4 et le groupe réactif est C = ONHNH 2. Les dihydrazides sont fabriqués par la réaction d'un acide organique avec de l'hydrazine . Il existe d'autres dihydrazides avec différents squelettes, également fréquents, y compris isophtalique dihydrazide (IDH) et dihydrazide sébacique (SDH).

| Résumé : |
An ambient-temperature self-crosslinkable acrylic resin was synthesized by solution polymerization, with ethanol as solvent; butyl acrylate (BA), methyl methacrylate (MMA), acrylic acid (AA), hydroxypropyl acrylate (HPA), and diacetone acrylamide (DAAM) as monomers; and adipic acid dihydrazide (ADH) as crosslinker. The resin could be diluted by water. The resin was used for PE film ink, and its curing behavior and film properties were studied. FTIR and DSC results indicated that the reaction between ketone carbonyl and hydrazine groups could occur during film curing at ambient temperature and improved glass transition temperature (T g) of the film by 12.67°C. Crosslinking density of film increased with DAAM content and m(ADH)/m(DAAM) ratio. Adhesion on PE film increased with DAAM content, while it first increased then decreased with m(ADH)/m(DAAM) ratio. Water absorption of film decreased with DAAM content, while it first decreased then increased with m(ADH)/m(DAAM) ratio. The optimal m(ADH)/m(DAAM) ratio and DAAM content in this experiment are 0.8:1 and 2%, respectively. Compared with ambient-temperature self-crosslinkable emulsion, this water-soluble resin shows film not only with the same adhesion, but also without any shrinkage void, indicating better film-forming ability on PE film. The ambient-temperature self-crosslinkable water-soluble acrylic resin shows excellent potential application in water-based ink for PE film because of good film-forming ability and adhesion and low water absorption. |
