地沟油对天然橡胶性能的影响

Influence of Waste Food Oil on the Properties of Natural Rubber

将餐饮用地沟油处理后用作天然橡胶(NR)增塑剂,并与大豆油、古马隆树脂和机油对比,研究其对胶料性能的影响。结果表明:地沟油胶料的物理性能与大豆油胶料接近,地沟油增塑效果与大豆油相近;与古马隆树脂和机油相比,地沟油NR胶料硬度减小,拉伸强度和拉断伸长率增大,磨耗量减小,地沟油增塑效果好;地沟油用量为4份的胶料综合物理性能最好。

The waste food oil was modified and applied in natural rubber （NR） as a plasticizer. The influence of waste oil on the properties of NR was investigated, and compared with soybean oil, Coumarone resin and regular oil. The plasticizing effect of waste oil was better than that of coumarone and regular oil, and was very close to soybean oil. Its plasticizing mechanism was in line with the reactivity plasticizing mechanism. The physical properties of waste oil filled NR was similar as soybean oil filled NR. Compared with Coumarone resin and regular oil, the hardness of NR filled with waste oil was lower, the tensile strength and elongation at break are higher, and the abrasion loss was smaller. The experimental results showed that the optimized addition level of waste oil was 4 phr.
