| 中文摘要: |
| 研究新型天然胶乳生物保存剂（简称生物保存剂）在标准胶制备中的应用，并与传统保存剂氨进行对比。结果表明：随着生物保存剂和氨质量分数的增大，天然胶乳的保存时间延长，当生物保存剂的质量分数大于0.010（按干胶计）时，天然胶乳的保存时间超过10 h；与采用氨保存的天然胶乳制备的标准胶相比，采用生物保存剂保存的天然胶乳制备的标准胶凝固用酸（甲酸）量大幅度减小，回收率较高，灰分含量、杂质含量、挥发分含量和塑性初值较大，塑性保持率和门尼粘度较低，胶料物理性能无明显差异，生产成本较低，生产环境改善。 |
| 英文摘要: |
| The application of the new biological preservative for natural rubber latex in the process of standard Chinese rubber（SCR WF） was studied，and compared to ammonia，the traditional preservative. The results showed that the preservation time was prolonged with the increase of mass fraction of preservative （biological preservative or ammonia） in the natural rubber latex. When the mass fraction of biological preservative was greater than 0. 010（based on the weight of dry rubber），the preservation time was longer than 10 h. Compared with the SCR WF that was made of natural rubber latex preserved by ammonia， the amount of coagulation acid（formic acid） for the SCR WF made of natural rubber latex preserved by biological preservative was significantly reduced，the product recovery rate was higher，the ash content， impurity content，volatile matter content and initial plasticity were greater，the plasticity retention index and Mooney viscosity were smaller，the production cost was lower，the production environment was improved， and the physical properties of the compound showed no significant difference. |
