Development of low cost natural rubber floor tile product with fire resistant property and using high finesse ethylene vinyl acetate plastic waste as filler

Abstract

This research aims to develop the natural rubber and ethylene vinyl acetate (EVA) plastic floor tile with flame resistance property. The 6 ratios of natural-rubber STR 20: zinc oxide: stearic acid: sulfur: mercaptobenzothiazole: diphenyl guanidine: EVA plastic: antimony trioxide were equal to 100: 5: 2: 3: 0.5: 0.2: 20: 0, 100: 5: 2: 3: 0.5: 0.2: 20: 20, 100: 5: 2: 3: 0.5: 0.2: 20: 40, 100: 5: 2: 3: 0.5: 0.2: 20: 60, 100: 5: 2: 3: 0.5: 0.2: 20: 80, and 100: 5: 2: 3: 0.5: 0.2: 20: 100 by weight or phr. The samples are ground by two-roll mill and formed by compression molding at 150 degree Celsius with 30x30x0.2 cm of dimension for 4: 29 to 5: 19 minutes. The properties of the natural-rubber floor tiles were tested under ASTM standard. From the results, it was found that the natural rubber and ethylene vinyl acetate plastic floor tile with flame resistance property was the suitable ratio for using as the rubber floor tiles in building and extinguished a fire by themselves. The antimony trioxide effected to increase the density, hardness, and thermal conductivity, and decrease the tensile strength, tear strength, and wear resistance properties of the natural rubber and EVA plastic floor tiles
