NOVELTY - Aqueous damping coating comprises 25-40 pts. wt. emulsion, 1-1.5 pts. wt. water, 0.5-5 pts. wt. water-retaining agent, 5-12 pts. wt. aqueous organic silicon resin, 0.2-1.2 pt. wt. dispersant, 0.5-5 pts. wt. moisturizer, 8-18 pts. wt. carbon fiber, 30-50 pts. wt. inorganic filler, 0.5-5 pts. wt. foaming agent, 0.2-1.2 pts. wt. antifoaming agent and 0.5 2.5 pts. wt. thickener. USE - The aqueous damping coating is used for automobiles. ADVANTAGE - The aqueous damping coating for automobile uses specific components with specific content to achieve overall better interaction, compared with the existing technology, solves the problem of bubbling during high-temperature baking, increases the thickness of the dry film, and has an excellent damping effect in a wide temperature range. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of the aqueous damping coating comprising (S1) mixing the emulsion, water and the water-retaining agent to obtain a mixed solution, (S2) adding the aqueous organic silicon resin, the dispersant, the moisturizer, the carbon fiber, the inorganic filler and the foaming agent to above mixed solution in sequence for high-speed dispersion, adding the antifoaming agent and the thickener slowly, and stirring evenly to obtain the aqueous damping coating.
