【 摘 要 】

Some mechanical properties of composite material based on scrap tyres and polyurethane type polymer binder were investigated to underline the significance of binder reactivity on selected mechanical properties of the composite material. Compressive stress and compressive modulus of elasticity E at 10% deformation and Shore C hardness were investigated. Connection was observed between the above-mentioned selected mechanical properties of composite material and reactivity of the polymer binder. It was confirmed previously that the crosslinking degree of polyurethane type binder separately and therefore at the same time mechanical properties of binder were strongly connected with water as a significant factor during the hardening of the polymer. The special objective of this work is to investigate connection between selected mechanical properties of the composite material, content and reactivity of the polymer binder under invariable composite material moulding and hardening conditions.
