The Effect of Nano-Filler on the Damping Properties of Polyacrylic Damping Paint
The dynamic mechanical properties of the blends of polyacrylic ester and various nano-fillers and the effect of nano-filler on the damping properties of polyacrylic ester damping paint were studied by using dynamic mechanical analysis (DMA) in this paper. The experiment results showed that the glass-transition temperature (Tg), loss factor peak value and effective damping temperature range for the polyacrylic ester damping paint changed correspondingly after blended with various nano-fillers. The damping properties and effective damping temperature range of the polyacrylic ester damping paint would be improved effectively by adding nano-polyacrylic ester rubber filler; the nano-silicon dioxide could enhance the damping properties for the polyacrylic ester damping paint, but the degree of improvement for effective damping temperature range was inferior to nano-polyacrylic ester rubber filler; and the nano-calcium carbonate could also improve the damping properties of the damping paint, but the effective damping temperature range was hardly improved.
