Abstract

Abstract: The fluorine-containing electron beam curing polyurethane acrylate was prepared by hexamethy-lene diisocyanate triplolymer, hydroxyethyl acrylate and hydroxyl fluorine-containing acrylate. The expected products were proved by FTIR and ¹H NMR. The rheological properties of the two-phase mixed system of the product and solvent, electron beam curing behavior and the properties of the cured coating were studied. The results show that the thixotropy of the mixed system has positive thixotropy, the absolute viscosity follows Sedden formula, and the viscous flow activation energy is about 44.8 kJ/mol. Electron beam cured coating has fine thermal stability, hardness, adhesion and glossiness.

Key words: Electron beam cured coating, Fluorine-containing polyurethane acrylate, Rheological property
