Abstract Slips are one of the main causes of accidents with personal injuries, during working or leisure time. Poor slip resistance may be a result of the properties of the floor surface. The general trend show that slip resistance performance improves with the surface roughness of the floor. However, too high surface roughness can impede safe and comfortable mobility, and floor maintenance is more difficult and costly. An anti-slip paint with nanoparticles can increase the roughness of a surface without generating macroroughness, thus avoiding these problems. In this work, 3 different types of nanoparticles have been added to a solvent-borne and a water-borne epoxy paint formulation in order to develop slip-resistance paints for walking surfaces. The obtained results indicated that nanoparticle-based paints present a great potential for reducing the floor surface slipperiness. In some cases, the slip resistance values drastically increased in wet conditions of a surface, from PTV (Pendulum test value) 35, reducing the falling risk probability that a pedestrian would experience when walking in a wet surface from 1 in 2 (PTV lower than 10) to 1 in 1,000,000 (PTV higher than 35). Moreover, this increase in PTV was achieved maintaining a roughness value lower than 3–5 microns, thus facilitating the cleaning and maintenance processes with respect to other conventional solutions. In this study, different parameters of the nanoparticles and the developed paints, which could affect the final properties of floor paints, are explored. This paper provides new insight in the relationship of the nanoparticle type and content with slipperiness and final surface appearance of the floor paint, as practical information for the formulation of slip resistance floor paint based on nanoparticles.

通过掺入纳米颗粒提高步行表面涂料的防滑性

摘要 在工作或休闲时间，滑倒是造成人身伤害事故的主要原因之一。防滑性差可能是地板表面特性的结果。总体趋势表明，防滑性能随着地板表面粗糙度的提高而提高。然而，过高的表面粗糙度会阻碍安全舒适的移动，并且地板维护更加困难和昂贵。含有纳米颗粒的防滑涂料可以在不产生宏观粗糙度的情况下增加表面的粗糙度，从而避免这些问题。在这项工作中，将 3 种不同类型的纳米粒子添加到溶剂型和水性环氧涂料配方中，以开发用于步行表面的防滑涂料。所得结果表明，纳米粒子涂料在降低地板表面光滑度方面具有巨大潜力。在某些情况下，从 PTV（钟摆测试值）35 开始，在潮湿的表面条件下，防滑性值急剧增加，将行人在潮湿表面行走时遇到的跌倒风险概率从 1:2（PTV 低于10) 到 1,000,000 分之一（PTV 高于 35）。此外，实现了 PTV 的这种增加，保持了低于 3-5 微米的粗糙度值，从而促进了与其他传统解决方案相比的清洁和维护过程。在这项研究中，探索了纳米颗粒和开发的油漆的不同参数，这些参数可能影响地坪漆的最终性能。
