The rate of cross-linking for Pt and peroxide cure silicone rubbers

This dataset contains measurements on the cross-linking of two silicone rubber variants (radical initiated cross-linking and cross-linking by addition) examined with differential scanning calorimetry (Mettler Toledo DSC1) and moving die rheometry (Alpha technologies RPA 2000). Differential scanning calorimetry measurements have been conducted with four different heating rates for both types of silicone rubber. Isoconversional kinetic predictions on the rate of cross-linking have been made with the Vyazovkin method based on the DSC data. Calculated data contains conversation curves, activation energy curves, and isothermal kinetic predictions. Data on isothermal measurements made with a moving die rheometer is included for comparison. The handling time for addition cure silicone has been examined with DSC, by measuring the change in enthalpy, onset, and peak values as a function of time after combining part A and part B of addition cure silicone rubber material. The data shows that the Vyazovkin method can also be used to make accurate predictions for cross-linking rate of Pt and peroxide cure silicone rubbers.

本数据集收录了两种硅橡胶品种（自由基引发交联和加成交联）的交联反应测量数据，这些数据通过差示扫描量热法（Mettler Toledo DSC1）和移动模具流变仪（Alpha technologies RPA 2000）进行检测。针对两种硅橡胶，均以四种不同的加热速率进行了差示扫描量热法测量。基于差示扫描量热法数据，采用 Vyazovkin 方法对交联速率的等转化反应动力学进行了预测。计算数据包括转化曲线、活化能曲线以及等温动力学预测。此外，还包含使用移动模具流变仪进行的等温测量数据，以供比较。通过差示扫描量热法对加成固化硅橡胶的交联处理时间进行了研究，通过测量混合加成硅橡胶材料A、B两部分后随时间变化的焓变、起始点和峰值，考察了其处理时间。数据显示，Vyazovkin 方法同样适用于对铂和过氧化物固化硅橡胶的交联速率进行精确预测。
