The invention provides a method for preparing a
fluorine-free super-hydrophobic
textile surface, belonging to the technical field of
textile treatment. The method comprises the following steps: (a) preparing a
fog polymerization solution, namely taking methacrylates or acrylic esters as monomers, taking
divinyl benzene or
ethylene glycol dimethyl acrylic ester as a cross-linking agent, taking methacryloyloxyethyl
isocyanate as a curing agent and taking
dibenzoyl peroxide as an initiator to prepare an organic solution; (b) atomizing the
fog polymerization solution; and (c) initiating
precipitation and
polymerization of
fog drops. According to the method provided by the invention, an atomized
monomer solution and almost polymerized
monomer fog drops are attached on the
textile surface to control the use amount of the polymerized monomers, and the unattached fog drops can be repeatedly utilized. According to the method, the surface appearance of a
coating is adjusted by selecting an
organic solvent, the cross-linking agent and the concentration and the atomizing
treatment time, and a nano structure of the surface is increased; the
surface roughness can be improved without using inorganic nano grains.
