シリカゲル-銀系の抗菌粒子を樹脂内に混練・分散させた抗菌性樹脂の設計とその評価 Design and Evaluation of Antibacterial Resin with Antibacterial Silicagel-Silver Particles Mixed and Dispersed by Kneading
A fundamental study was conducted for the design of high-performance antibacterial kneaded resin containing ABS as basic resin, and a antibacterial agent of the silica gel-silver type. The following findings were revealed:<BR>(1) The effectiveness (performance) of antibacterial resin correlates with the dispersion effectiveness number, defined as the product of the dispersion and area ratio of antibacterial agent particles.<BR>(2) Optimum kneading conditions were established which enable the higher-effectiveness of the antibacterial resin (killing almost 100% of bacteria). It is suggested that the three-dimensional contour line graph should be used to represent the kneading conditions and the antibacterial resin effectiveness, in order to establish the optimum kneading conditions to ensure effective antibacterial resin. Such a graph could reduce the number of preliminary experiments.
