▎ 摘　　要

NOVELTY - Method for preparing film-forming substance for high temperature and superheated steam coatings involves (i) preparing polysiloxane by reacting after mixing siloxane monomer, aqueous ammonia, ethanol and deionized water and (ii) using epoxy resin to modify polysiloxane to obtain epoxy modified polysiloxane, which is film-forming substance (A). USE - Method for preparing film-forming substance for high temperature and superheated steam coatings. ADVANTAGE - The method has high temperature water vapor resistance of the composite coatings prepared.
