1.前言汽车的发明,橡胶硫化的发现至今已有100年了,即使说汽车工业是随着橡胶工业的发展而发展起来的,这也并不过分。因为橡胶具有宝贵的高伸长高回弹性能,所以保持着其它材料无法代替它在一些重要领域的地位。但如果看一下如表1所示的近年来的发展趋势,与塑料用量在不断增加的情况相比较,它的使用量已从过去不变的状态向减少的趋势变化。 1. Foreword Automotive invention, rubber vulcanization has been discovered for 100 years, even if the automotive industry is developed with the development of the rubber industry, which is not excessive. Because of the valuable high elongation and high resilience of rubber, retaining other materials can not replace its status in some important areas. However, if we look at the recent trends in Table 1 as shown in Table 1, their use has changed from the unchanged status to the decreasing trend compared with the continuous increase in the amount of plastic used.
