Abstract:
A method for forming an inorganic passivation material is provided. The method includes mixing about 5 to 80 parts by weight of trialkoxysilane, about 10 to 80 parts by weight of tetraalkoxysilane, and about 1 to 30 parts by weight of catalyst to perform a reaction at pH of about 0.05 to 4 to form an inorganic resin material. The inorganic resin material is modified by phosphate ester to form an inorganic passivation material, wherein phosphate ester is about 0.1-10 parts by weight based on 100 parts by weight of the inorganic resin material. An inorganic passivation material and a passivation protective film produced therefrom are also provided.
