Problems solved by technology

This brings some problems to endow the fabric with water-repellent, oil-repellent and antistatic functions at the same time. At present, there are mainly step-by-step finishing method and same-bath method to deal with, but the step-by-step finishing method increases the processing procedures, and two kinds of finishing should be considered at the same time. The viscosity and influence between the agents will greatly reduce the antistatic and water and oil repellency; there are compatibility problems between different functional agents, so in the same bath method, due to the compatibility and mutual influence of functional agents, it is also It will greatly reduce the effect of antistatic finishing and water and oil repellent finishing, so it is very necessary to invent a water and oil repellent antistatic finishing agent
For example, CN102108638B invented a durable waterproof, oil-proof, antistatic and antibacterial functional coating glue, which has the effect of water-repellent, oil-repellent and anti-static, but because of its anti-static part and its water-repellent and oil-repellent part At the same time, it acts as a side group, and they have a great influence on each other, so the water-repellent, oil-repellent and antistatic effect is not ideal. It is necessary to seek a better water-repellent, oil-repellent and 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...
