Problems solved by technology

Although polyoxyethylene ether emulsifiers of fatty alcohols overcome the shortcomings of alkylphenols, their emulsifying ability and influence on colloidal polymerization of polymers are quite different from those of alkylphenols, and the performance of emulsions is similar to that of alkylphenols. The emulsion ratio is also quite different; this is because the carbon number of the fatty alcohol in the fatty alcohol polyoxyethylene ether is mostly more than 12, the crystallinity is strong, the critical micelle concentration increases, the dosage increases, and the emulsifying ability decreases, and because the dosage increases, The water resistance of the emulsion film has declined; on the other hand, because the wetting performance of fatty alcohol polyoxyethylene ether is not as good as that of alkylphenol polyoxyethylene ether, it is found that the color development of the coating film is greatly reduced after being used in latex paint
