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

Abstract

The present application discloses an alkyl benzyl alcohol polyoxyethylene ether ammonium phosphate and a preparation method thereof. The molecular structure of the alkyl benzyl alcohol polyoxyethylene ether ammonium phosphate includes a hydrophobic group and a hydrophilic group, and the molecular structure is as follows: Wherein, R in the molecular formula is an alkyl group, and n=3-50. The alkyl benzyl alcohol polyoxyethylene ether ammonium phosphate prepared by the invention does not contain APEO, has good wetting, penetrating, emulsifying, dispersing, solubilizing and washing functions, and can be used as emulsifier, textile auxiliary, detergent , dispersant, softener, etc., completely replace alkylphenol polyoxyethylene ether emulsifier, widely used in detergents, personal care products, textiles, papermaking, petroleum, pesticides, pharmaceuticals, printing, synthetic rubber, water-based emulsions, coatings, Ink, glue, plastic and other industries.

Description

technical field [0001] The present disclosure generally relates to the technical field of synthesis of polymer additives, in particular to emulsifiers, and in particular to alkylbenzyl alcohol polyoxyethylene ether ammonium phosphate and a preparation method thereof. Background technique [0002] Emulsifiers containing alkylphenol polyoxyethylene ether compounds (APEO for short) have good wetting, penetrating, emulsifying, dispersing, solubilizing and washing effects, and are mainly used as emulsifiers for pesticides, textile auxiliaries, and disinfectants. Foaming agents, detergents, dispersants, emulsifiers, softeners, dyeing auxiliaries, fiber oils, crude oil demulsifiers, etc., are widely used in detergents, daily necessities for personal care, textiles, papermaking, petroleum, metallurgy, pesticides, and pharmaceuticals , printing, synthetic rubber, water-based emulsion, plastics and other industries. APEO includes nonylphenol polyoxyethylene ether (NPEO for short) acc...
