Synthesis and properties of electron beam curing waterborne polyurethane acrylate
摘要
Abstract
A new preparation method of waterborne polyurethane acrylate was developed. With this method the hydrophilicity of polyurethane acrylate was improved by assembling ionic groups on the molecular structure of chain extender, and the immiscibility of polyurethane acrylate with water was resolved. The polyurethane acrylate prepared by this method was characterized by Fourior-transformed infrared spectroscopy (FTIR) and ]H nuclear magnetic resonance (:H NMR). Its stability with water, viscosity, electron beam curing behavior and cured properties were studied. The results showed that the as-prepared product had water storage stability and the emulsion particle sizes decreased with increasing water content in the range from 0. 50 to 0. 75. The product properties cured by electron beam, such as thermal stability, hardness, adhesion, gloss, flexibility were excellent.关键词
