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。
In this paper,the development,basic characteristics and processing techniques of eucommia ulmoides gum(EUG)in China and its application in tire were introduced.EUG possessed the outstanding characteristics of both rubber and plastics and had partially crystalline state due to its ordered transmolecular structure.With EUG,the heat generation and rolling resistance of rubber compound was effectively reduced,and the wear resistance,fatigue resistance and wet skid resistance of the tire were improved.The blend of EUG and NR could be used in tread compound,and the blends of EUG,BR and SBR were suitable for sidewall compound,bead filler,shoulder wedge and carcass cord compounds.With development of tire production and EUG processing technology,EUG would be widely applied in tire industry in the future.
