Effects of Nano Alumina on Some Physical and Mechanical Properties of an Acrylic

This investigation aims to show some effects of nano alumina particles in an acrylic resin that is used as a protective coating against wear. The loads of nano alumina in samples are 3, 5, 7, 9, 11 percentage “based on solid” and a sample without nano alumina marked as reference. Liquid samples were examined by a rheometer to observe effects of nano alumina particles on viscosity then a turbidity instrument was utilized to observe transparency changes of clear coats that contains diverse amount of nano alumina. By means of a Taber abrasion, wear index of samples were achieved; afterward micro hardness used to consider the effects of nano alumina in hardness of samples.Adding nano alumina does not impart significant alternation in viscosity. Turbidity results show haziness in higher load percentage of nano alumina. Wear index of samples in high weight fractions dropped dramatically. Micro hardness of cured samples does not differ significantly. J. Color Sci. Tech. 4(2010), 169-174© Institute for Color Science and Technology.
