NON-STICK CERAMIC COATING COMPOSITION AND PROCESS

摘要

A method of making a series of new non-stick ceramic coating materials prepared from organic-inorganic hybrid materials, including silica sol, MTMS, FAS and PDMS (Polydimethylsiloxane) using the sol-gel process. The hybrid materials have good mechanical properties and are fashioned into a main ceramic network and good non-stick properties from organic non-stick compounds. The non-stick ceramic coating consists of two layers applied to cookware and for other applications. Methods of preparing a substrate coated with the non-stick ceramic coating are also disclosed.

1. A method of making a non-stick ceramic coating for a substrate, comprising the steps of:
making a first component by:
adding a colloidal silica sol to at least one organoalkoxysilane of chemical formula RxSi(OR′)4-x, wherein R represents an organic substituent, R′ represents an alkyl group, and 0≦x<4, and a catalyst to effect a condensation reaction;adding a solvent;adding a colorant in particulate form; and,mixing to form a first stable binder solution; making a second component by:
adding an organoalkoxysilane and a catalyst, said organoalkoxysilane including a minor portion of fluoroalkylalkoxysilane;adding a solvent;mixing to form a second stable binder solution; mixing said first component and said second component, thereby producing a two-component mixture; and, aging said two-component mixture.
