Problems solved by technology

Organic fluorine materials have poor low temperature resistance, and organic silicon materials have poor resistance to chemical media, which limits their application fields to a certain extent.
[0004] The performance of a single-component surfactant cannot meet the needs of the prior art, so it is urgent to design a modified composite surfactant to solve the problems of the prior art

Description

technical field [0001] The invention relates to a surfactant, in particular to a modified composite surfactant. Background technique [0002] Surfactant refers to a substance that can significantly change the interface state of its solution system by adding a small amount. With fixed hydrophilic and lipophilic groups, it can be aligned on the surface of the solution. The molecular structure of surfactants has amphiphilicity: one end is a hydrophilic group, and the other end is a hydrophobic group; the hydrophilic group is often a polar group, such as carboxylic acid, sulfonic acid, sulfuric acid, amino group or amino group and Its salt, hydroxyl group, amide group, ether bond, etc. can also be used as polar hydrophilic groups; while hydrophobic groups are often non-polar hydrocarbon chains, such as hydrocarbon chains with more than 8 carbon atoms. Surfactants are divided into ionic surfactants (including cationic surfactants and anionic surfactants), nonionic surfactants, ...
