Description
技术领域
本发明涉及一种橡胶材料,尤其是涉及一种合成橡胶配方及其制备方法,属于橡胶生产领域。
背景技术
橡胶护舷是码头或船舶上使用的一种充气或充水用的橡胶缓冲制品。主要用以减缓船舶与码头或船舶之间在靠岸或系泊时的冲击,保护船舶、码头免受损坏。一般由纯橡胶或者橡胶与金属骨架、帘布层组成。用贴合成型法经模压硫化而成,或先模压成型后用硫化罐硫化。橡胶护舷广泛用于港口、码头和船舶上。目前所使用的护舷主要是用废弃的轮胎安装在船体、码头上,虽然能起到隔离的作用,但是由于废弃轮胎的弹性不足,在出现碰撞时还是会损伤船体和码头。针对废弃轮胎,人们也在致力研究其他结构的护舷,但是它们的结构不合理,在碰撞时弹性差,回弹力不足,因此防撞能力差、缓冲性能差;而且在使用过程中,常常还会造成护舷撕裂,从而导致使用寿命短。
