| 摘 要： | 采用水溶性、不挥发性的广谱抗菌剂——三嗪衍生物(HY)作为鲜胶乳的新型无氨保存剂,研究了HY对胶清凝固总用酸量、胶清胶及胶清胶硫化胶片性能的影响。结果表明,HY保存胶清凝固总用酸量大大减少,除氮含量略微超标外,胶清胶的各项指标均达到1级胶清胶的标准,胶清胶的塑性保持率(PRI)明显提高。HY胶清胶硫化胶片的拉伸强度和耐热氧老化能力均优于氨胶清胶硫化胶片。热解重量分析(TGA)结果表明,HY和氨胶清胶硫化胶片热氧降解均为2步反应,耐热氧降解能力基本相同。

| Abstract: | A triazine derivative-HY,which is a soluble and non-volatile broad-spectrum bactericide,was used as a new non-ammonia preservation reagent for fresh natural rubber latex.The effect of HY on the performance of skim latex solidified with acid,skim rubber,skim rubber vulcanized film was also studied and the results showed that the total acid amount for coagulation of HY save skim latex decreased dramatically.The various of standard of skim rubber reached to the standard of level 1skim rubber,and the PRI of the skim rubber increased distinctly,except the nitrogen content exceeded the standard slightly.The testing of TGA elucidated the race of the hot oxygen degradation for HY and ammonia skim rubber vulcanized film was divided into two steps,however,there is no difference in heat-resistant oxygen degradation ability. |
