Preparation method of water-repellent and oil-repellent antistatic finishing agent

Abstract

The invention relates to a preparation method of a water-repellent and oil-repellent antistatic finishing agent. The water-repellent and oil-repellent antistatic finishing agent is prepared from methyl methacrylate, n-butyl acrylate, perfluoro-n-butyl ethyl methacrylate, 3-propyl-2-enoyl acyloxy propane-1- sodium sulfonate, sodium dodecyl benzene sulfonate, fatty alcohol-poly-oxyethylene ether AEO-9, and n-butyllithium. A polymer with a fluorocarbon group on the side group and an antistatic group on the end group or close to the end group can be obtained by controlling the reaction sequence, time and equivalent ratios of reaction monomers to directionally influence the structure of the polymer to a certain extent. The finishing agent containing the polymer as main component has excellent water-repellent, oil-repellent and antistatic properties.

Description

technical field

[0001] The invention relates to a preparation method of a finishing agent, in particular to a preparation method of a finishing agent with water-repelling, oil-repelling and antistatic properties. Background technique

[0002] With the development of society, people's demand for fibers and textiles is increasing, and their performance requirements are getting higher and higher, which requires multifunctional composite finishing. At present, the effects of various functional finishing agents are relatively single, and there are compatibility problems among single-functional finishing agents.

[0003] Water- and oil-repellent finishing and anti-static finishing are inherently contradictory. Anti-static finishing agents eliminate static electricity by absorbing moisture in the air and improving the electrical conductivity of fabrics, while water- and oil-repellent finishing agents reduce fiber surface tension. Make it lower than the surface tension of water and...
