摘　　要：硫化天然橡胶物理松弛时间的测量裘怿明刘从伟时锋傅政（青岛化工学院橡胶工程学院青岛２６６０４２）关键词硫化天然橡胶，应力松弛速率，数值计算方法，曲线拟合高分子热运动的特点之一是存在松弛现象，通常，人们描述高分子材料的松驰速度采用松驰时间τ［１］．实际...The physical relaxation behaviour of vulcanized rubber is described by the conception of relaxational velocity( V SR ). The results showed that using V SR =5 i =1 A iτ ie (-t/τ i) velocity equation is better to reflect stress relaxation behaviur of vulcanized rubber and have influence on relaxation at different temperatures. The V SR is considered more scientifically to describe vulcanization natural rubber of physical relaxation behaviour.

关 键 词：硫化天然橡胶 应力松弛速率 松弛时间
