Abstract Slip is considered the leading cause of injury-producing accidents. The slip resistance of floor materials has been investigated through the course of this experimental work. Different tiles have been prepared and both the coefficient of friction and the generated electrostatic voltage have been measured. Tiles surfaces were composed of both epoxy and other inlaid thermoplastic polymeric materials. The polymeric materials considered through the present experimental work were polyamide, polymethyl methacrylate (PMMA), polytetrafluoroethylene (PTFE), polypropylene (PP), polystyrene (PS) and polyvinyl chloride (PVC). Friction coefficient was measured by means of a test rig prepared to measure both the normal and tangential force. Electrostatic surface voltage was measured by means of a surface voltmeter. Test specimens were loaded and slid against a rubbery counterface. Tests were carried out under dry and wetted conditions. Water, detergents and oil were used to wet the sliding surface. Observations showed that addition of thermoplastic polymers into epoxy showed higher friction coefficient relative to pure epoxy. PTFE showed friction values higher than 0.8. Epoxy tiles filled by 30 % PS can be recommended to be used as flooring material. At water wetted sliding, epoxy tiles with 40% PVC showed the highest friction coefficient. Friction coefficient increased as the content of PS increased, where the maximum friction coefficient was observed at 50 % PS. At the detergent wetted medium, epoxy tiles with 20% PS showed the highest friction coefficient. At oily sliding, epoxy tiles with 10% polypropylene showed the highest friction coefficient. Besides, test specimen filled by 10% PTFE showed remarkable increase in the generated surface. |
