Abstract

The invention discloses a fluoride-contained textile finishing agent and a preparation method thereof. The fluoride-contained textile finishing agent is copolymerized by emulsion via oxa perfluoroalkyl (methyl) acrylate monomer, higher aliphatic alcohol (methyl) acrylate monomer, crosslinking monomer and enhanced monomer in the presence of a complex emulsifying agent, an emulsion accelerator, a chain transfer agent, a stabilizing agent and an initiating agent; vinylidene chloride or chloroethylene is used as the enhanced monomer; the mass of the enhanced monomer is 5-40% of total mass of the monomer; polypropylene glycol or segmented copolymer of the polyethylene glycol and polypropylene glycol is used as the emulsion accelerator; the mass of the emulsion accelerator is 5-50% of total mass of the monomer; stearoylbenzoylmethane is used as the stabilizing agent; and the mass of the stabilizing agent of 0.5-5% of the total mass of the monomer. The fluoride-contained textile finishing agent has the advantages of high washable degree and does not pollute the environment.

Description

technical field [0001] The invention belongs to the field of fabric finishing auxiliaries, and in particular relates to a fluorine-containing fabric finishing agent and a preparation method thereof. Background technique [0002] At present, the fluorine-containing monomers in fluorine-containing fabric finishing agents are mainly perfluorooctylsulfonyl compounds (PFOS) and perfluoroalkylethyl (meth)acrylates. Among them, perfluorooctane sulfonyl compounds are currently banned due to potential dangers to human health and the environment. Perfluoroalkyl ethyl (meth)acrylates may also be degraded to form PFOS, and may also be degraded to form perfluorooctanoic acid ammonium (PFOA), so they are also potentially dangerous to human health and the environment. [0003] Chinese patent document CN101148825A discloses a water- and oil-repellent finishing agent for organic fluorine fabrics using heterooxyperfluoroalkyl (meth)acrylate as a fluorine-containing monomer. The heterooxyper...
