Provide a detailed explanation of the mixing temperature and time of a small internal mixer

December 26, 2023

A high mixing temperature is conducive to the plastic flow and deformation of raw rubber and rubber materials, which is beneficial for the wetting of the surface of solid compounding particles and the mixing and powder absorption of rubber. However, it also reduces the viscosity of the rubber material, which is not conducive to the crushing and dispersion of compounding particles. Excessive mixing temperature can accelerate the thermal oxidative aging of rubber, leading to a decrease in the physical and mechanical properties of vulcanized rubber, resulting in the phenomenon of over mixing; It can also cause scorching of the rubber material, so effective cooling measures must be taken during the mixing process of the internal mixer; But the temperature should not be too low, otherwise there will be a phenomenon of adhesive dispersion.

Extending the mixing time can improve the dispersion of the compounding agent in the rubber material, but it can also reduce production efficiency. If the mixing time is too long, it is easy to cause the physical and mechanical properties of the vulcanized rubber to be damaged due to excessive mixing, and it can also cause an increase in the "thermal history" of the rubber, which is prone to scorching. Therefore, the mixing time of the rubber should be shortened as much as possible.
