The steel sheet which covered the inorganic organic fusion body, inorganic organic fusion body tunic, those production methods, and application liquid null for inorganic organic fusion body tunic formation

摘要

PURPOSE: To obtain a highly corrosion- and heat-resistant steel sheet with good processability coated with hard coating. ;CONSTITUTION: A steel sheet is coated with a solution in which an alkoxide an alkoxide derivative, a hydrolyzed alkoxide, or a mixture hydrolyzed of an alkoxide derivative and a dialkyl dialkoxyl silane is contained. The coated sheet is heat-treated at 100-600C. The ratio of the dialkyl dialkoxyl silane as an organic component to the alkoxide and the alkoxide derivative which become an inorganic component or a molar ratio of the organic component/the inorganic component is 8.0-0.1. In this way, a steel sheet coated with a 0.5-50m thick film of an inorganic-organic composite material is obtained in which the skeleton of an inorganic polymer consisting of an M-O-M linkage (M: a metal atom or a semi-metal atom) is substituted by O-Si(R)₂-O group (R: an alkyl group). The coated sheet can be used for purposes in which a post-coated steel sheet has been used so far because a steel sheet pre-coated with an organic polymer could not respond the requirements.;COPYRIGHT: (C)1995,JPO
