研究橡胶增塑剂A1220运动粘度-温度特性,推算橡胶增塑剂A1220在不同温度下的运动粘度。用运动粘度测试值通过拟合和经验式计算,得到拟合运动粘度-温度方程和经验式运动粘度-温度方程,并将计算值与测试值进行对比。结果表明:橡胶增塑剂A1220在100～160℃内的拟合方程计算的运动粘度准确度较高,在180～200℃内的经验式方程计算的运动粘度准确度较高。

The kinematic viscosity-temperature characteristic of rubber plasticizer A1220 was studied to calculate kinematic viscosity at different temperatures.The methods of data fitting and empirical formula were adopted to establish viscosity-temperature equations using test data.The calculated data from the equations were compared with the test data.The results showed that,the fitting equation was more accurate when temperature was 100~160℃and the empirical equation was more accurate when temperature was 180~200℃.
