AI Technical Summary
Traditional reactive surfactants have poor compatibility in aqueous and organic phase systems with large polarity differences, and are prone to phase separation or insufficient solubilization. Furthermore, reactive groups are prone to premature self-polymerization or hydrolysis under strong acid, strong alkali or high temperature conditions, which affects storage stability and compatibility with existing processes.
A highly compatible reactive surfactant is formed by using isophorone diisocyanate monoacrylate, trimethylolpropane triacrylate, methacryloyloxyethyl cocoyl betaine, methoxy polyethylene glycol-methacrylate, crosslinking comonomer, initiator and chain transfer agent, and by limiting the proportion and controlling the reaction conditions, so as to achieve covalent bonding to the polymer backbone.
It improves the compatibility and reactivity of reactive surfactants in high-polarity acrylate systems, high-hydrogen-bonded waterborne PU systems, and high-crosslinking-density UV-cured systems, avoids phase separation and migration, and enhances storage stability and film-forming performance.
