Abstract
Description
Technical Field
[0001] This utility model relates to the field of anti-slip mat technology, and more specifically, to a TPE biomimetic suction cup anti-slip mat and its self-cleaning surface. Background Technology
[0002] Anti-slip mats, as an important safety protection device, are widely used in bathrooms, kitchens, industrial platforms, vehicles, and other places requiring anti-slip properties. Traditional anti-slip mats mainly rely on surface friction and gravity to achieve their anti-slip effect, but they are prone to failure in complex environments such as dampness and oil stains. With the development of bionic technology, bionic suction cup anti-slip mats based on the principle of bio-adsorption have gradually become a research hotspot; the adsorption mechanisms of organisms such as octopuses and geckos have provided new ideas for the design of anti-slip mats.
[0003] Currently, anti-slip mats on the market mainly include rubber anti-slip mats, silicone anti-slip mats, and PVC anti-slip mats. These mats suffer from problems such as insufficient adhesion, easy accumulation of dirt, difficulty in cleaning, and short lifespan. Traditional rubber anti-slip mats, while inexpensive, have limited adhesion and are prone to aging; silicone anti-slip mats are flexible but have poor anti-slip performance in oily environments; PVC anti-slip mats are durable but lack sufficient adhesion. Furthermore, existing anti-slip mats generally lack self-cleaning capabilities, requiring frequent cleaning after dirt accumulation, which not only increases maintenance costs but also affects anti-slip performance. In medical, food, and other environments with strict hygiene requirements, traditional anti-slip mats are insufficient, thus necessitating the development of a TPE biomimetic suction cup anti-slip mat with a self-cleaning surface.
