Abstract

In this study, the polymer blends based on natural rubber latex and acrylic resin was prepared. It was then utilized as a binder for paint. The blending ratios between natural rubber latex and acrylic resin were varied from 30/70, 40/60, 50/50, 60/40, and 70/30 (w/w) where the natural rubber latex was pre-vulcanized prior to be blended with acrylic resin. The investigation was monitored through the physical and mechanical properties of the blends. Highest tensile strength and elongation at break were found at the blending ratio at 30/70 (w/w) of natural rubber latex and acrylic resin. This may be attributed to the compatibility between elastic phase of the natural rubber and hard phase of acrylic resin. When adding higher ratio of natural rubber latex, the tensile strength and elongation at break dropped continuously, indicating inhomogeneity of these two phases. To confirm the compatibility of the blend at 30/70 (w/w), the gel content was also observed. It is clear that such blend completely dissolved in non-polar solvent unlike other blending ratios. Therefore, this blending ratio is highly suggested and appropriate for applying as binder for paint.
