Abstract: [Objective] To develop high-performance water-based damping coatings with highwear resistance and high rigidity over a broad temperature range for application in vibration and noisecontrol—enabling vibration suppression and noise absorption/dissipation.[Methods]The waterborne damping coatings were prepared by replacing mica powder(type A/B)with silicon carbide(SiC)of different mass fractions. and the effect of SiC on the composite loss factor of the coatings was evaluatedusing the ISO 6721-3 cantilever beam method. The wear resistance of the coating was investigated.[Results]Replacing part of the mica powder with SiC increased the damping factor by more than 30%, broadened the effective temperature range of 5 ℃ and improved the wear resistance of the coating.[Conclusion]SiC significantly enhanced energy dissipation capacity through interfacial interactionsand pore-filling effects. This silicon carbide filling strategy can substantially improve the dampingperformance and wear resistance of waterborne coatings,promoting their development in the field of vibration and noise reduction.
