Study on Storage Stability of Waterborne Hydroxyl Acrylic Dispersion-Based Amino Baking Paint
The waterborne hydroxyl acrylic dispersions with a core-shell structure are prepared by two-step method.The effects of the core-shell mass ratio,acrylic acid dosage and neutralization degree on the storage stability of waterborne hydroxyl acrylic dispersion-based amino baking paint are investigated.The experimental results indicate that the storage stability of amino baking paint is the best when the core-shell mass ratio is 9:1,the amount of acrylic acid used is 2％,and the degree of neutralization is 100％.In addition,the cured film shows high glossiness,hardness,adhesion and excellent impact resistance.
