| Abstract/Summary |
This paper presents a method for the experimental determination of reaction heat of rubber curing, which is based on solution of the transient heat conduction equation with an internal heat source. The experimental technique of the LIST method, which was originally developed for measuring thermal diffusivity of rubber compounds, was used to estimate the reaction heat of rubber curing. Value of 43 x 103 J kg−1 was obtained for curing reaction heat of a commercial rubber sample with the following composition: 47.54 mass % of natural rubber (SMR 20), 9.00 mass % of synthetic rubber (SKD 2), 3.00 mass % of synthetic rubber (Vestenamer 8012), 2.69 mass % of sulfur, 0.97 mass % of accelerator (Vulcacid DZ), 0.07 mass % of inhibitor (Duslin G-80), and 36.73 mass % of carbon black and other components. The overall error in predicting the reaction heat by this method is less than 15 %.
