Products and uses of different combinations of hydrophilic groups in fatty alcohol polyoxyethylene ethers
The fatty alcohol polyoxyethylene ether contains a large amount of hydrophilic ethylene oxide segment and terminal hydroxyl group, wherein the terminal hydroxyl group can be condensed with the isocyanate group, and the cationic polyurethane prepolymer is selected by using the fatty alcohol polyoxyethylene ether. End-capping, the hydrophilic group of the ethylene oxide segment and the long alkyl chain can be simultaneously introduced into the polyurethane
In the structure of the surfactant, the introduction of ethoxy group can effectively improve the acid and electrolyte resistance, broaden the application conditions and range, and have greater market application potential. Among them, in the chemical fiber industry, the glass fiber emulsifier and the chemical fiber spinning oil component are used to improve the spinning property of the chemical fiber. Used as a cleaning agent in metal processing, it is easy to remove surface oil and facilitate subsequent processes. It can be used as an emulsifier in the polymer emulsion polymerization industry and as a penetrant and emulsifier for fruit tree pesticides in the latex and agricultural industries, respectively.
