Aging Property of Eco-Friendly Anticorroslon Organic Coating Film for Telecommunication Plant

摘要

Telecommunication facilities are protected against long-term weather exposure by certain prevention technologies. One such technology, namely polymeric materials, is available for coating onto steel or galvanized steel. Physical and chemical aging is an important factor that affects the properties of polymer and, therefore, of coatings. The present study is focused on the effect of aging on the adhesive performance and rheo-logical property of new eco-friendly anticorroslon organic coating film that we are developing, which has a low volatile organic compound (VOC) content of less than 10%. Exposure to accelerated thermal cycling certainly had an influence on the coating film in that it degraded its adhesive strength and affected the storage modulus and loss tangent. E' and tan 5 were found to evaluate likely planes of failure in multilayer combinations of film. During aging at room temperature, the solvent might evaporate and reach equilibrium. A significant phenomenon was observed, namely that the strengthening effect might relate to the application of tensile stress before the complete evaporation of the solvent.
