Abstract:
This disclosure provides a fluorine-containing mixture and a fluorine-containing super-oleophobic microporous membrane using the fluorine-containing mixture as a raw material, as well as preparation methods and applications for the fluorine-containing mixture and the fluorine-containing super-oleophobic microporous membrane. The fluorine-containing mixture of the present disclosure comprises, by weight percentage, the following components: Component A: 50%˜90%; Component B: 3%˜25%; Component C: 0%˜35%; Component D: 0%˜3%; wherein Component A comprises high molecular weight polytetrafluoroethylene homopolymer or copolymer dispersion resin; Component B comprises one or more fluorine-containing alkyl acrylate monomers; Component C comprises one or more fluorine-free acrylates; Component D comprises high temperature free radical initiator. There's no need to add inflammable or explosive lubricating oil, making the process highly safe; and the obtained fluorine-containing super-oleophobic microporous membrane has high waterproof, air-permeable, oil-resistant and washable performance, in line with the needs of a new generation of waterproof and air-permeable protective clothing.
