Adhesion improvement at polyester fabric-silicone rubber interface by plasmas of argon and air to obtain conveyor belt

Abstract

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.

Water-Soluble, Self-Healing, and Debonding Primer for the Interface between Silicone Leather and Polydimethylsiloxane Composites

“…Generally, the bonding properties of composites depend upon surface wettability and compatibility of the two different materials . However, few studies have focused on interface bonding between PDMS and other materials. , As a result of low surface energy, the PDMS surface is hard to wet and bond by conventional primers [such as PU, polyethylenimine, poly­(vinyl alcohol), polyacrylate, and epoxy resins] during real-life applications. The undercoating treatment may be a simple way to bond the polypropylene surface, − which could be a cost-efficient method to improve adhesion between the silicone leather and PDMS surface.…”

Structure–Property Performance of Irradiated Sponge Rubber Blend Nanocomposites Containing h‐BN, GO, V2O5, and Adhesion on Cotton Fabric for Positive Electrode in Flexible Supercapacitors

“…To enhance the adhering, silicone rubber and polyester fabric coating by plasma treatment were addressed. [21] In contrast, adhesion between the cotton fabric and rubber was proved to be enhanced by treatment with a mild alkaline solution before subjecting to heat-hardening polyhydric phenolaldehyde-latex. [22] Radiation-induced crosslinking utilizing electron beam (EB) or gamma rays is favored over traditional chemical techniques as no additional chemical additives are required for curing, and it provides several advantages such as high crosslinking speed, low operation cost, efficient penetration of the EB or gamma ray within the material, and crosslinking uniformity.…”

In Situ Synthesis of Copper Nanoparticles on Dielectric Barrier Discharge Plasma-Treated Polyester Fabrics at Different Reaction pHs

“…27,28 Plasma treatment has been stated as an environmentally friendly and cost-effective technique to modify materials. 29 This method involves the generation of reactive free radicals, photons, atoms, and ions, which change the surface and facilitate the incorporation of functional groups such as hydroxyls, carboxyls, amines, and amides. As a result, the adhesion of MNPs may be enhanced and may occur as hydrogen bonds, van der Waals forces, or dipolar interactions.…”
