Abstract

Rubber gaskets find wide applications in steel structures. Gaskets are usually used on the edges or on the nail hole positions. These are the weakest positions, where corrosion starts, whether the structure is protected by paint or by other methods. In this work, anticorrosive pigments were incorporated in rubber formulations. They are tested by corrosion protection when used as gaskets with steel panels. Results showed that the presence of anticorrosive pigments in rubber gaskets prevents early rusting under it in comparison with the blank. Zinctetroxy chromate pigment exhibited the highest rust inhibiting power when chloroprene rubber formulations were used. The change of the pigment percent barely affect the quality of protection when syrenebutadiene rubber formulation were used. Zinc tetroxy chromate pigment improved the physicomechanical properties of chloroprene rubber under investigation. The used formulations can tolerate thermal oxidative aging at 90C up to 8 days. The rate of vulcanization was not affected by increasing the concentration of the inhibitive pitments.
