Multi-functional environmental coating composition with mesoporous silica nanomaterials

摘要

A new generation environmental friendly water-based coating composition which exhibits excellent coating film properties is disclosed. Said water-based coating composition comprises mesoporous silica nanoparticles in organosilica, water, and a film-forming catalyst, and optionally with a small amount of ethanol. Method for manufacturing said water-based coating composition and the use thereof are also disclosed.

主权项

1. A highly chemically tunable, transparent and rapidly drying water-based environmental coating composition that provides scratch resistance and water resistance to a surface effected therewith comprising one or more water-dispersible mesoporous silica nanoparticles capable for dispersion and film formation, triethoxyvinylsilane and/or polymethylhydrosiloxane, water and a film-forming catalyst that catalyses hydrolysis of said triethoxyvinylsilane and/or polymethylhydrosiloxane so as to accelerate formation of film from the coating composition such that a touch-drying time of the coating composition is less than two hours, wherein said environmental coating composition has less than 100 g/L of volatile organic chemicals, and a color of said surface is unaffected or a color incorporated into the coating composition is imparted to the surface to be effected with the coating composition.
