1. a kind of poly-vinegar acid oxygen zirconium precursor body colloidal sol spinning solution, is obtained as follows:

  • By zirconium oxycarbonate;

    Glacial acetic acid;

    Six nitric hydrate yttriums;

    Auxiliary agent;

    Absolute methanol=100;

    (35~55);

    (8~22);

    (1~5);

    The weight ratio of (100~400), weighs zirconium oxycarbonate, glacial acetic acid, six hydration nitre respectivelySour yttrium, auxiliary agent and absolute methanol, mix under 10~60 DEG C, stirring condition and fully dissolve, and dense in 30~40 DEG C of decompressionsContract and obtain water white transparency, homogeneous poly-vinegar acid oxygen zirconium precursor body colloidal sol spinning solution, 1.0~1.2g/ml of density (25 DEG C measure),For preparing sub-micron zirconium oxide crystal fibre;

    Described auxiliary agent be selected from polyvinylpyrrolidone, polyacrylamide, polyvinyl alcohol, polyacrylic acid, polyethylene glycol oxide,PPOX, polyvinyl acetate, polyvinyl acetate, poly- methylcellulose, hydroxy alkyl cellulose, alkylcellulose,One or more in glucan, polyethylene glycol etc..
