几种不同品级国产标准天然橡胶性能的对比
|
摘要
选取了4种不同品级的国产标准天然橡胶SCR5、SCR10、TSR20、SCRWF,对比分析了4种标准胶在加工性能、结构、力学性能、动态力学性能、热稳定性及耐屈挠龟裂等方面的差异。结果表明,SCR10、TSR20的综合性能最优,更适合应用于绿色低滚动阻力轮胎的胎面胶领域;SCRWF因其较宽的相对分子质量分布更适合应用在高断裂伸长率及抗动态疲劳领域;SCR5虽然在力学性能方面表现优异,但加工及热稳定性方面略显不足。
Four native standard natural rubbers,SCR5,SCR10,TSR20 and SCRWF,had been selected,and the comparisons between the properties of these rubbers were investigated,including process ability,structure,physical and mechanical properties,dynamical mechanical properties,thermal stability and anti-flex cracking performance.The results showed that SCR10 and TSR20got the best combination property and might fit the need of tread with green tire.SCRWF could adapt to the fields that need high elongation at break and anti-dynamic fatigue performance for its wide molecular weight distribution.SCR5 achieved a worse performance on process and thermal stability,even though it got an excellent expression on physical and mechanical properties.
