Description
Technical field: the present invention relates to a kind of coating for metal surfaces coating composition and preparation method thereof, particularly a kind of coating for metal surfaces coating composition that contains silicone resin and preparation method thereof.
Background technology: common alkyd ready-mixed paint is formed by modulation such as Synolac, pigment, pigment extender, siccative and organic solvents, only decoration function is played in the metallic surface, is higher than under 105 ℃ the operating condition and be lower than-45 ℃, easily sticks up layer, peeling; These deficiencies have determined the limitation of common alkyd ready-mixed paint on using, and have influenced industrial protection and decoration to metal.Though in order to address the above problem, each scientific research institutions, each chemical enterprise, develop various composition coating coating one after another, wherein are no lack of various resin paints, but also just have one's own knack in a certain respect, and over-all properties all can't satisfy the needs of industry in individual events such as sticking power, acidproof, alkaline-resisting, salt tolerant, oil resistant, moisture resistances.
Summary of the invention:, the invention provides a kind of metal surface protection and ornamental organosilicon alcohol acid ready mixed paint coating composition of being used in order to address the above problem.The coating that forms with this organosilicon alcohol acid ready mixed paint coating composition of the present invention has over-all propertieies such as strong adhesion, acidproof, alkaline-resisting, salt tolerant, oil resistant, moisture resistance, has solved industrial to the protection of metallic substance and the problem of decoration effectively.
Another object of the present invention provides a kind of preparation method of aforementioned coating composition.
The technical solution used in the present invention is: a kind of organosilicon alcohol acid ready mixed paint coating composition, it is characterized in that it is made of by weight percentage following component,
Solvent oil 5%～10% silicone resin 45%～60%
