- Abstract
Large amounts of peanut shells were abandoned each year in China and the abandoned peanut shells were subjected to incineration or landfi ll, which not only polluted environment, but also wasted resources. So, a household fi ll material with fl ame retardant and antibacterial functions was fabricated with abandoned peanut shell and discarded thermoplastic polyurethane by plasticizing, blending and hot pressing. The main factors that affect the fl ame retardant performance and the regression model of limiting oxygen index were obtained by response surface analysis. The regression model helped to predict materials fl ame retardant ability and achieve the optimal preparation condition, which as follows: the peanut shell mass fraction 49.5 %, ammonium polyphosphate mass fraction 4.4 %, Thermoplastic polyurethanes (TPU) fl ame retardants mass fraction 14.2 %, under these conditions, the limiting oxygen index of materials was 32.78 %. While after added 3 wt% Tetraneedle like ZnO whiskers at the same condition, the limiting oxygen index was 32.7 %, and the antimicrobial ratio of Staphylococcus aureus, Escherichia coli and Salmonella reached 96.03, 96.98 and 92.33 % respectively.
