摘 要
 本研究主要探討天然橡膠(Natural Rubber;簡稱NR)與聚丁二烯橡膠(Polybutadiene Rubber;簡稱BR),在摻合不同比例時,對加工性相互影響效應,實驗上以Mooney Viscometer及Monsanto Viscometer探討NR/BR在硫化過程中之初期黏度及硫化反應,另一方面,並以SEM及DMA探討NR/BR 摻合膠成形物之表面形態及分子運動性,分析NR/BR Blend之相容性。以及硫化膠之力學性質及熱老化後物性及結構變化。
  實驗結果顯示, NR/BR摻合膠隨著NR含量之增加初期黏度有下降趨勢,而在硫化速率方面,隨著NR含量的增加硫化速率明顯的增加;實驗結果發現140℃為NR/BR合膠之最適加工溫度。另一方面,經由DMA分析之結果顯示NR/BR摻合膠之分子運動性具有相互影響作用,隨BR含量增加分子網目之主運動均朝低溫測移動。NR/BR摻合膠之抗張強度、撕裂強度隨著NR摻合量的增加而增加。另外在壓縮性能方面,BR膠之剛性率較高,使得硫化膠之塑性變形與彈性變形在同荷重下相對減小,因此隨著BR膠摻合量的增加其壓縮變形率減少而壓縮剛性增加。在固定溫度下於不同時間下所作的老化實驗,可得知NR/BR摻合膠在長期受熱後其力學性能呈現下降的趨勢,並且NR膠之損失程度較BR為高,顯示BR膠有較佳之耐熱老化性;且由於分子鏈裂化使的NR/BR摻合膠之玻璃轉移溫度有往低溫移動之趨勢,並且損失正切也隨熱老化時間增加而增加。

Abstract
In this study,the interaction to process properties of NR/BR blend with various blending rations are studied. It is the initial Mooney Viscosity and vuclcanization cure are studied by means of Mooney Viscometer and Monsanto Reheometer . On the one hand,the surface form,molecular motion,and compatibility of the NR/BR blend are studied by means of SEM and DMA.The mechanical property of vulcanized rubber and physical properties after hot aging and the change of structure.
The experimental results of NR/BR blend show that the initial viscosity decreased with increasing NR content. In the aspect of the vulcanized rate,the more NR content increase,the faster the vulcanized speed will be. The optimum processing condition of NR/BR blend is at 140℃.On the one hand,the NR/BR blend is interactive from DMA anaysis.The motion of become interpenetrate polymer network structure moves toward low temperature with increasing BR contents.The tensile strength and tear strength increase with increasing NR content.In the aspect of compression property,owing to the higher stiffness of BR blend,plasticity deformation and resilience deformation of vulcanite decreases relatively in a same weight.Therefore,compression set decrease with increasing BR blend contents,but compression stiffness increases under the same load.By an life aging experiment,which is in a fixed temperature,but in different time,NR/BR blend presents a tendency to decrease and NR is higher than BR in losing degree;it shows that BR is better than NR in hot aging property.Due to molecular is broken,glass-tremsition temperature of NR/BR blend has a tendency to move towards low temperature and loss tangent increases with increasing the time of life resistance.
Keywords:Natural Rubber,Polybutadiene Rubber,Mooney viscosity,molecular motion,aging,compression stiffness
