Effects of plasma treatments on the adhesion between polyester fabrics and silicone rubber coating

Conveyor belt production requires good adhesion between coating layer and fabrics. Adhesion is important for good mechanical properties of belts. Silicone rubber has gained importance in food carrying because it is harmless when being in contact with food materials. The aim of this study is to enhance the problematic adhesion properties between polyester fabrics and silicone rubber coating by plasma treatment. The fabrics are modified by air or argon RF plasmas under different power and time conditions. Influence of plasma parameters was investigated by adhesion strength tests. To investigate changes on adhesion, wettability measurements, X-ray photoelectron spectrometry (XPS), Atomic Force Microscopy (AFM), scanning electron microscopy (SEM) were performed untreated and plasma treated polyester fabrics. After plasma treatments, the coating adhesion between fabric and coating polymer was increased approximately for 4.6 times for argon and 4.3 times for air plasmas.

Rubber Coatings

A pollution flashover along an insulation surface—a catastrophic accident in electrical power system—threatens the safe and reliable operation of a power grid. Silicone rubber coatings are applied to the surfaces of other insulation materials in order to improve the pollution flashover voltage of the insulation structure. It is generally believed that the hydrophobicity of the silicone rubber coating is key to blocking the physical process of pollution flashover, which prevents the formation of continuously wet pollution areas. However, it is unclear whether silicone rubber coating can suppress the generation of pre-discharges such as corona discharge and streamer discharge. In this research, the influence of silicone rubber coating on the characteristics of surface streamer discharge was researched in-depth. The streamer ‘stability’ propagation fields of the polymer are lower than that of the polymer with silicone rubber coating. The velocities of the streamer propagation along the polymer are higher than those along the polymer with silicone rubber coating. This indicates that the surface properties of the polymer with the silicone rubber coating are less favorable for streamer propagation than those of the polymer.

Alumina Trihydrate

This study aims to evaluate the hydrophobicity of vulcanized silicone rubber coatings at room temperature (RTV SR) with loads of alumina trihydrate (ATH) and nanosilica (NS) in the polymeric silicone rubber matrix, in order to obtain coatings ATH/NS/RTV SR to cover the surface of glass electrical insulators. The coatings were characterized by scanning electron microscopy (SEM), testing in salt spray chamber, loss test and recovery of hydrophobicity. These coatings showed varying sizes of agglomerates and heterogeneous distribution of particles within the matrix RTV SR. In the test in salt spray chamber smaller leakage current values was observed for the insulator coating with the ATH/NS loads. In the loss and recovery of the hydrophobicity test the best result was observed for insulating load RTV SR / 20: 1 (ATH: NS).
