Abstract

The invention relates to a fluorine-containing surfactant, and concretely relates to a preparation method of a novel nonionic environmentally-friendly fluorine-containing surfactant. The preparation method of the novel nonionic environmentally-friendly fluorine-containing surfactant least comprises the following steps: adding perfluoroalkyl acrylate, polyethylene glycol acrylate, a peroxide initiator solution and a solvent into a reaction kettle, and performing a reaction at 40-60 DEG C for 4-6 h to obtain the surfactant. The novel nonionic environmentally-friendly fluorine-containing surfactant prepared by adopting a special process and components is green and environmentally friendly, conforms to the theme of green development, and has good thermal stability and good surface activity.

Description

technical field [0001] The invention relates to the technical field of fluorine-containing surfactants, in particular to a preparation method of a novel nonionic environment-friendly fluorine-containing surfactant. Background technique [0002] There are many types of surfactants, and surfactants containing elements such as fluorine, silicon, phosphorus, and boron are called special surfactants. Due to the introduction of elements such as fluorine, silicon, phosphorus and boron, the surfactant is endowed with more unique and excellent properties. Fluorinated surfactants are one of the most important varieties of special surfactants. [0003] However, C8 perfluorosurfactants represented by perfluorooctanoic acid may cause cancer or affect the safety of reproductive function, and their use has been strictly controlled in Europe and the United States. C6 perfluorosurfactants are currently under debate. However, fluorine-containing surfactants play an important role in the fie...
