Investigation on Properties of a New CB/WPUA Composite Coating

摘要：

By grafting carbon black (CB) with multifunctional waterborne polyurethane acrylate (WPUA), a series of environmental-friendly CB/WPUA black coatings with different CB contents were prepared in this study. The chemical structures of the products at different synthesis stages analyzed by Fourier-transform infrared spectroscopy (FT-IR), and the influence of carbon black content on the properties of coatings was systemically investigated. The experimental results demonstrated that the WPUA/CB composite coatings with more CB contents had higher viscosities and impaired unsaturation conversions of WPUA. However, the coating containing 4 wt％ of CB obtained the best water resistance and tensile strength owing to incorporate organic-inorganic structures, which is of importance for practical application.
