| 中文摘要: |
| 合成两种适用于橡胶材料的新型有机抗菌剂2-（1，3-苯并噻唑-2-基硫烷基）-N-（3，4-二氯苯基）乙酰胺（PMBT）和N-（3，4-二氯苯基）-2-{[4-（4-吡啶基）-2-噻唑基]硫代}乙酰胺（PMTT）。相比于传统抗菌剂，两种新型有机抗菌剂不但具有一定的促进硫化作用，同时具有更高的生物安全性、稳定性和抗菌持久性，有效避免传统抗菌剂对人体的损害和对环境的污染。将两种有机抗菌剂用于天然橡胶（NR）胶料中，研究其对NR胶料性能的影响，结果表明：有机抗菌剂PMBT和PMTT具有一定的促进硫化作用，能一定程度上提高NR硫化胶的交联密度，并可增大NR硫化胶的拉伸强度和撕裂强度，但对NR硫化胶的拉断伸长率和耐热氧老化性能影响不大；分别采用1.5份有机抗菌剂PMBT和1份有机抗菌剂PMTT即可实现NR硫化胶对大肠杆菌和金黄色葡萄球菌的有效抑制。 |
| 英文摘要: |
| Two novel organic antibacterial agents suitable for rubber materials，namely 2-（1，3-benzothiazol-2-ylthio）-N-（3，4-dichlorophenyl） acetamide（PMBT） and N-（3，4-dichlorophenyl）-2-{[4-（4-pyridinyl）-2-thiazolyl]thio} acetamide（PMTT） were synthesised.Compared to conventional antibacterial agents，these two novel organic antibacterial agents not only exhibited a certain accelerating effect on vulcanization，but also possessed higher biosafety，stability and durability，effectively mitigated the damage to human body and pollution to environment caused by traditional antibacterial agents.These two organic antibacterial agents were applied to natural rubber（NR） compounds，and their influences on the properties of NR compounds were studied.The results indicated that the organic antibacterial agent PMBT and PMTT possessed certain accelerating effects on vulcanization，which could moderately enhance the crosslinking densities of NR vulcanizates，and improved the tensile strengths and tear strengths.They had little affects on the elongation at break and heat-oxgen aging resistance.By using 1.5 phr organic antibacterial PMBT and 1 phr organic antibacterial PMTT，effective inhibition of Escherichia coli and Staphylococcus aureus in NR vulcanizates cound be achieved. |
