Effect of softener on regeneration process of reclaimed rubber
Huajun Tire Factory
Shanxi odorless reclaimed rubberThe manufacturer said that reclaimed rubber is a physical and chemical process of crushing, heating, mechanical treatment, desulfurization and other physical and chemical processes of waste rubber products or vulcanized rubber products, from elastic state to certain plasticity, viscosity, re-vulcanization and reuse of rubber; The regeneration process of reclaimed rubber requires the combination of softener, activator, oxygen, heat and mechanical shear force to break some molecular chains and cross-linking points of vulcanized rubber.
Among them, the role of softener in the regeneration process of reclaimed rubber is very important.
Shanxi tasteless reclaimed rubber manufacturers said that rubber softener is a low molecular substance, which is easy to enter the vulcanization network during the vulcanized rubber regeneration process and play the role of expansion and plasticization. The softener will use the vulcanized rubber to relax the network structure, increase the oxidation penetration, provide convenient conditions for the oxidation fracture of the cross-linked network structure, and reduce the possibility of the rubber network structure in the vulcanized rubber, thereby speeding up the regeneration process of the reclaimed rubber.
Shanxi odorless reclaimed rubber manufacturers said that the rubber softener itself has a certain viscosity and is soluble in rubber. After high temperature desulfurization, it can be retained in the rubber, significantly increasing the plasticity and viscosity of the finished recycled rubber. During the processing of reclaimed rubber, the amount of softener should be controlled between 10 and 20 parts. Commonly used are coal tar, pine tar, rosin, tall oil, dipentene and so on. Different kinds of softeners can produce different reclaimed rubbers.
