Abstract

The invention relates to the field of polymers for daily use chemicals, in particular to fatty alcohol polyoxybutene ether polyglycerol ether and a preparation method and application thereof. The fatty alcohol polyoxybutene ether polyglycerol ether has a structure as shown in a formula (1): wherein R is alkane with the carbon atom number of 4-12, m is the average polymerization degree of polyoxybutylene ether, m is equal to 3-10 and n is the average polymerization degree of polyglycerol ether and is equal to 11-20. The fatty alcohol polyoxybutylene ether polyglycerol ether provided by the invention has the characteristics of high foaming degree, high self-defoaming speed and high dirt-removing power, and can reduce the washing and showering times in the rinsing process when being applied to detergents, thereby saving water resources.

Description

technical field [0001] The invention relates to the field of daily chemical polymers, in particular to a fatty alcohol polyoxybutylene ether polyglyceryl ether and a preparation method and application thereof. Background technique [0002] Detergent is a necessity in people's daily life and work. It is used for decontamination and cleaning. It has played a very important role in protecting human health, cleaning the environment and industrial production for a long time. Detergents are usually formulated according to a special formula, but their main components generally include surfactants, builders and additives, etc., which play a role in wetting, penetration, air bubbles, etc. by reducing the interfacial tension between water and dirt. Emulsification, solubilization and dispersion, etc., make the dirt from the laundry and disperse into the water, so as to achieve the purpose of decontamination. [0003] Among them, surfactants are the most important components in deterge...
