本研究以氯丁橡膠(CR, Chloroprene Rubber)作為主膠，其兼具各項機械性質，用途十分廣泛，主要用做電線批覆、膠管、醫療用或工業用手套、膠粘劑等。為了補強橡膠的拉伸性能、抗撕裂能力和耐磨性等性能，本研究以碳黑作為主要填料，透過碳黑粒徑大小和用量來調節補強橡膠的效果。
首先以微型混煉機依不同碳黑粒徑大小、碳黑份量之配方製作出橡膠試片，並透過硫化試驗及木尼黏度試驗分析其硫化膠性質，再進行物理機械性質分析比較配方間差異，如比重、硬度、拉伸強度、熱老化、耐油性、耐磨耗及撕裂強度，並由上述實驗歸納出兩種變因對於氯丁橡膠之影響效應。
由實驗得知填料份量之增加對木尼黏度、硫化速率、硬度、比重、耐磨性、耐油性呈正相關效應；對伸長率呈現負相關效應。而隨著粒徑越小，其對木尼黏度、硫化速率、硬度、拉伸強度、耐磨性及撕裂強度呈正相關效應；對伸長率則呈現負相關效應。

This study uses chloroprene rubber as the main rubber. It has various mechanical properties and has a wide range of uses. It is mainly used for wire coating, hose, medical or industrial gloves, adhesives, etc. In order to strengthen the rubber's tensile properties, tear resistance and wear resistance, this study uses carbon black as the main filler, and adjusts the effect of reinforcing rubber through the size and dosage of carbon black.
First, use a micro-mixer to make rubber test pieces according to different carbon black particle size and carbon black content formulas, and analyze the properties of the vulcanized rubber through a vulcanization test and a woody viscosity test, and then analyze the physical and mechanical properties to compare the differences between the formulas , Such as specific gravity, hardness, tensile strength, thermal aging, oil resistance, abrasion resistance and tear strength, and summarized the effects of two variables on the chloroprene rubber from the above experiments.
It is clear from the experiment that the increase in filler content has a positive correlation effect on mooney viscosity, vulcanization rate, hardness, specific gravity, abrasion resistance and oil resistance. In addition, it has a negative correlation effect on elongation. With the smaller particle size, it has a positive correlation effect on mooney viscosity, vulcanization rate, hardness, tensile strength, abrasion resistance and tear strength. Moreover, it has a negative correlation effect on elongation.
