| 中文摘要: |
| 介绍我国杜仲橡胶的发展概况、基本特性、加工工艺及其在轮胎中的应用。杜仲橡胶的主要成分为反式-聚异戊二烯，具有橡塑二重性和结晶特性，可有效降低轮胎的生热和滚动阻力，提高轮胎的耐磨、耐疲劳和抗湿滑性能。杜仲橡胶与天然橡胶并用可以制备轮胎胎面胶，与顺丁橡胶和丁苯橡胶并用可以制备轮胎的胎侧胶、三角胶、胎肩垫胶和胎体帘布胶等。随着轮胎生产和杜仲橡胶加工技术的不断提高，杜仲橡胶将得到广泛的应用。 |
| 英文摘要: |
| In this paper，the outlines of development，basic characteristics and processing techniques of eucommia ulmoides gum（EUG）in china and its application in tire were introduced.EUG was of duality of rubber and plastics and the feature of crystallization owing to the trans-molecular structure.It could effectively reduce the heat generation and rolling resistance，and could improve wear resistance，fatigue resistance and wet skid resistance of the tire.The blends of EUG mixing with NR could be used to make tread compound，and mixing with BR and SBR would be suitable to make sidewall compound，bead filler，shoulder wedge and carcass cord compound.With development of tire production and EUG processing technology，EUG would be widely applied in tire industry in the future. |
