Abstract
In order to reduce the use of active diluent in UV-curable resin,low viscosity dendritic UV-curable resin was synthesized.Firstly,the 1.0 generation dendritic macromolecule polyamide-amine(G1.0PAMAM)was synthesized using ethylenediamine as the reaction nucleus by means of a two-step iterative reaction of Michael addition and amidation with methyl methacrylate at 25 ℃.Secondly,hydroxy-terminated PAMAM macromolecules were synthesized by reacting hydroxyethyl acrylate with half-generation PAMAM.Finally,dendritic PAMAM resin was synthesized by modifying maleic anhydride(MA)and glycidyl methacrylate(GMA).It was characterized by Fourier transform infrared spectroscopy(FT-IR).The viscosity-temperature properties of PAMAM UV-curable resin were studied.Good thermal stabilities of G0.5PAMAM and G1.5PAMAM UV-curable film were determined,adhesive force were 1,the hardness of pencil were 3H and 4H respectively,the flexibility were 3 mm and 5 mm respectively,and effects of molecular structure on the properties of the coating were discussed in details.关键词
