Many products do not need to be tested for water absorption. The water absorption of carbon black studied here is the effect of carbon black on the water absorption of neoprene rubber. The water resistance of chloroprene rubber used in water for a long time has a significant impact on its electrical insulation and physical and mechanical properties, and its water resistance is closely related to the compounding agent.
Study on Water Absorption Properties of Carbon Black
The combined water of carbon black itself is very little, mainly absorbing water. During soaking in water, water is gradually adsorbed on the surface of carbon black particles and internal cavities. As time goes by, the amount of adsorbed water of carbon black gradually increases.
Effect of Carbon Black on Water Absorption of Neoprene Rubber
As the number of carbon black increases, the water absorption weight gain rate of chloroprene rubber increases, and the water resistance performance decreases. It can be seen that carbon black has an adverse effect on the water absorption performance of chloroprene rubber.
The content of this article is that relevant researchers prepared multiple sets of samples through basic matching tests, and through a one-year follow-up test, investigated the influence of carbon black on the water absorption properties of neoprene rubber. The experimental results are of great reference value.
