| 中文摘要: |
| 研究防老剂DH对NR，SBR，BR和NR/SBR并用胶的热空气老化和天候老化的防护作用，并与防老剂4020，BLE和RD进行对比试验。结果表明，在NR，SBR和BR胶料中，对于耐热空气老化性能，防老剂DH的防护效果优于防老剂RD和BLE，劣于防老剂4020。对于耐天候老化性能，防老剂4020的防护效果最佳；在NR和BR胶料中，防老剂DH优于防老剂BLE和RD；在SBR胶料中，防老剂DH，BLE和RD的防护效果相近。防老剂DH对胶料基本无污染。在实际应用配方胶料中，用110～115份防老剂DH替代2份防老剂BLE或RD可以改善胶料的耐热空气老化和耐天候老化性能；如果用1份防老剂DH替代2份防老剂RD或BLE，则分别可降低胶料成本约17.5或107.5元·t -1，具有一定的经济效益。 |
| 英文摘要: |
| The effect of antioxidant DH on the hot air aging and weathering aging properties of NR，SBR，BR and NR/SBR blend compounds was investigated and a comparative test of DH was made to antioxidants 4020，BLE and RD.The results showed that for hot air aging properties，DH was superior to RD or BLE，but inferior to 4020 in NR，SBR or BR compounds；for weather aging properties，4020 was the best，and DH was superior to BLE or RD in NR or BR compounds，but similar to BLE or RD in SBR compound；and generally DH was a non-pollutioned antioxidant.The hot air aging and weather aging properties of prodution compound were improved by using 110～115 phr of DH instead of 2 phr of BLE or RD；and the compound costs were decreased by 17.5 or 107.5 RMB yuan·t -1 respectively when 1 phr of DH was used to replace 2 phr of RD or BLE. |
