| Abstract: | This paper introduces the principles of dispersion of hydroxyl acrylic resin in water and the selection of polymerization solvent and the co-solvent of water dispersion. It summarizes the latest development in preparing high solids and low viscosity water-borne hydroxyl acrylic resin, including higher temperature of polymerization, choosing peroxide di-tert-pentyl to synthesize low molecular weight and low-degree crosslinking polymers, synthesizing core-shell structure, or branching structure hydroxyl acrylic resin from glycidyl versatate, vinyl versatate, methacrylic acid benzyl ester, (meth) acrylate isobornyl ester, methacrylic acid cyclohexyl ester, methyl acrylic acid tert-butyl cyclohexyl ester and other functional monomers, preparing a specially-structured or low-molecular weight copolymer by using multi-step polymerization technology (with a brief analysis of its principle). In conclusion, this article describes some existing problems about hydroxy acrylic resin aqueous dispersion, including water resistance, solvent resistance, stability, and film-forming properties, and proposes how to solve the above problems, including polymer structure, film-forming mechanism, and coating formulations. |
