輪胎用橡膠與天然黏土奈米混成化研究
Study on the Rubber/Caly Nanocomposites for Tire Application
摘要
中文摘要 本研究將有機黏土添加於苯乙烯丁二基橡膠製得之複合材料，雖然降低了機械性、0℃～20℃之Tanδ、和磨耗性，但是提高了乾抓地性能與降低了滾動阻力，也將以往在輪胎胎面膠中添加於高分子複材之親水性添加物(如：長纖、短纖、雞蛋殼粉、核桃殼粉、高嶺土或未改質之蒙脫土等….)來增加有限的輪胎抓地與抓冰性能，在本研究中探討將無機黏土改質為親油性有機黏土，取代一般高嶺土使增加其特性。 由於有機化黏土可以增加高分子複合材料的疏水性，應用於特殊輪胎雪地胎是可以幫助水分子的排除，或減少大面積水膜覆蓋、增加輪胎的排水性能，未來也可能提供更好、更安全的輪胎。 未來希望能將天然的蒙脫土或有機化改質型蒙脫土運用在輪胎領域，減少地球能源的損耗降低石油產物的使用，利用奈米級複合材料之耐久、耐熱、耐磨耗、抗老化等特性...，使高分子奈米級複合材料特性達到，結合綠色環保與節能的共同方向與目標。

Abstract In this experiment, although adding Styrene Monomer into Organoclay reduces the mechanical effect, Tanδ between 0℃and 20℃and wearing, it elevates the tread handling on dry ground and reduces rolling resistance. Moreover, it replaces the traditional tread compound which is added with high polymer hydrophilic additive, for example, ling fiber, short fiber, egg shell powder, walnut shell powder, Kaolin clay, or natural Na+-montmorillonite, to enhance limited gripping on icy or dry road condition. In the research, the clay is changed to Organoclay to replace Kaolin clay for quality improvement. Since such clay could escalate the hydrophobic of Polymer Nanocomposites, it is also helpful for enhancement of water draining while applied on special summer tires or winter tires. This could bring a better and safer tire compound in the near future. In the future, we hope to apply natural Montmorillonite and modified Montmo-rillonite on tire technology to decrease the wastage of natural resources and reduce the usage of petroleum. Meantime, utilizing the characteristics of macromolecule nanopolymer composites, like the endurance, heat tolerance, anti-wearing and anti-aging, to approach the goal of fuel saving and eco-friendliness.
