NOVELTY - Preparation of film plating liquid comprises adding titania sol, silica sol, zirconia sol, alumina sol, and/or fluoride to silicon-containing high molecular weight polymer; adding organic solvent and deionized water to prepare into base material; under stirring condition, adding absorbent or coupling agent to organic solvent to prepare into auxiliary material; adding to base material; stirring to obtain solution 3; under stirring condition, adding additive ingredient to diluting agent to prepare into auxiliary material 2; adding auxiliary material 2 to solution 3; and stirring.    USE - Preparation of film plating liquid for solar battery encapsulating glass (claimed).    ADVANTAGE - The method of preparing the film plating liquid prevents the shortages of film layer, which are bad uniformity, easy to crack, and bad adhesive attraction. After being exposed outdoor for a long time, the adhesive attraction, hardness, and salt and fog resistance of antireflection film can be increased to different degrees. Thus, the film plating liquid can meet the demand for the use of solar product in many climate environments.    DETAILED DESCRIPTION - Preparation of film plating liquid comprises:    (A) adding titania sol, silica sol, zirconia sol, alumina sol, and/or fluoride to silicon-containing high molecular weight polymer; and adding organic solvent and deionized water to prepare into base material;    (B) under stirring condition, adding absorbent or coupling agent to organic solvent to prepare into auxiliary material 1;    (C) adding auxiliary material 1 to base material at 60-1000 revolutions/minute (rpm); and stirring for greater than or equal to 20 minutes to obtain solution 3;    (D) under stirring condition, adding additive ingredient to diluting agent to prepare into auxiliary material 2; and    (E) adding auxiliary material 2 to solution 3; stirring for greater than or equal to 5 minutes at 15-60 rpm; and preparing into film plating liquid.    INDEPENDENT CLAIMS are included for:    (1) film plating liquid comprising (wt.%) silicon-containing high molecular weight polymer (50-90), titania sol, silica sol, zirconia sol, alumina sol, and/or fluoride (1-5), absorbent and/or coupling agent (0.1-5), additive ingredient (0.1-2), diluting agent (1-5), and organic solvent and deionized water (balance); and    (2) manufacture of solar battery encapsulating glass using spraying, soaking and coating, lifting and drawing, roller coating, rotatably coating, flow coating, and brushing coating, comprising coating the film plating liquid on a glass base material of cleaned and dried solar battery encapsulating glass; reinforcing the solar battery encapsulating glass processed by antireflection film; and cleaning the reinforced solar battery encapsulating glass with antireflection film.
