对比普通防老剂264,研究新工艺环保型防老剂264(简称新型防老剂264)对天然橡胶(NR)胶料的硫化特性、热氧老化性能及其耐水抽出性能的影响。结果表明,与普通防老剂相比,新型防老剂264对NR胶料的硫化特性影响不明显,其耐水抽出性能及胶料的耐热氧老化性能较好,更适合在潮湿的环境下使用。新型防老剂264在NR胶料中的用量以1～2份为宜。
Compared with ordinary antioxidant 264, the effect of new technology environment-friendly antioxidant 264 (new type antioxidant 264) on the vulcanization properties, thermo-oxidative aging properties and water-resistant extraction performance of natural rubber (NR) The results showed that compared with ordinary antioxidant, the new antioxidant 264 had no obvious effect on the vulcanization properties of NR compounds. The water-resistant properties of the new antioxidant 264 and the heat-resistant oxygen aging properties of the compounds were better, which were more suitable for use in humid environments. The new type of antioxidant 264 in the NR rubber compound to the amount of 1-2 parts is appropriate.
