Study on Curing Kinetics of Natural Rubber Dried by Microwave

Abstract:

In this article, the curing kinetics of natural rubber (NR) dried by microwave at frequency of 2450MHz was studied using vulcameter, as well as molecular weight. Seen from the results, the molecular weight distribution of NR dried by microwave was wide, the reaction rate of NR dried by microwave at any temperatures increased with conversion degree (α) increment and passed through a maximum at the value of α between 0.1 and 0.3, the peak height of α was increased with a shift in peak position towards a higher α value, which provided evidences that the curing behavior illustrated autocatalytic characteristics and depended on curing temperature.
