DETERMINATION OF THE HYDROXYL NUMBER OF GROUND TIRE RUBBER PARTICLES VIA MODIFIED TEST METHOD FOR ISOCYANATE GROUPS

Abstrakt

Nowadays, considering the environmental trends and law regulations associated with the circular economy, it is very important to seek for the methods of by-products and waste utilization. The example of such material, which requires the attention and recycling method is ground tire rubber generated during recycling of post-consumer car tires. It can be introduced into various polymer matrices as a filler, but to enhance its effectivity it is essential to guarantee the interfacial compatibility. Therefore, the fast and simple methods for determination of the waste rubber chemical structure are needed. In the presented paper, we are presenting the method for the determination of hydroxyl number of ground tire rubber, based on the modified standard test method for isocyanate groups. Hydroxyl number is used as a quantitative measure of the hydroxyl groups content, which is essential during manufacturing of multiple polymeric materials, such as polyurethanes, epoxy resins, polyesters or polyamides. Moreover, the presence of hydroxyls on the rubber surface may be exploited during compatibilization of composites.
