"Non-slip paint product for the treatment of walking surfaces, relative use, method of preparation and production kit"

DESCRIPTION

The present invention mainly relates to an anti-slip paint product particularly, but not exclusively, to be used as an anti-slip coating for walking surfaces such as, for example, the floors of community and professional environments, bathrooms and so on. Advantageously, the invention also refers to the use, to the method of preparation of a coating based on the aforementioned non-slip paint product and to the production kit of the latter,

In the community and industrial building sector, the execution of suitable flooring for the premises has always been of particular importance. In fact, the safety of walking on such floors represents in general a fundamental requisite, however, codified in the technical standards of the sector and in the legislative provisions for the supervision and protection of safety in the workplace. This safety is related to the ability of the flooring to prevent and / or considerably reduce the risk of falls due to slipping which, in turn, depends on the roughness of the flooring. For example, the DIN 51130 standard distinguishes the slipperiness of a floor that can be walked on with the feet shod according to the following five classes with increasing slipperiness:

R9 - entrance areas and stairs with access from the outside; restaurants and canteens; shops; surgeries; hospitals; schools.

R10 - common toilets and showers; small kitchens for restaurants; garages and basements.

R11 - environments for the production of food; medium-sized kitchens of catering establishments; work environments with a strong presence of water and mud; laboratories; laundries; hangar.

R12 - environments for the production of food rich in fats such as: dairy products and derivatives; oils and cured meats; large kitchens for catering establishments; industrial departments with the use of slippery substances; car parks.

R13 - environments with large amounts of fat; food processing.

The codes R9 - R13 that classify each aforementioned class are in turn related to the roughness of the pavement, expressed in the form of a specific interval, increasing from code R9 to code R13. Based on this guiding criterion, designers and installers adopt and employ different operating techniques to ensure the prescribed and correct roughness to a flooring.

According to a first example, a safe walking surface for walking is obtained thanks to the use of tiles with high surface roughness or by aggression of a walking surface with highly acidic substances that increase the pre-existing surface roughness of the surface.

A drawback that can be found in these operating techniques consists in the fact that the outer layer of the flooring is dotted with micro-craters which cause a weakening of the surface resistance and which represent suitable cavities for the accumulation of bacteria and pollution. A second drawback attributable in particular to the second of these operating techniques consists in the fact that it is a non-definitive treatment which must be repeated over time due to its rapid wear.

According to a second example, a safe walking surface for walking is obtained by affixing strips to corundum or silicon carbide.

A drawback of this solution consists in the fact that it affects the external appearance of the base support. In fact, it is not suitable for valuable walking surfaces such as marble stairs.

According to a third example, a safe walking surface for walking is obtained with the use of a mixture of structural epoxy resins and quartz sands or aluminum oxide.

A first drawback of this solution is found in the fact that it represents an invasive intervention capable of maintaining transparency for a short period due to the yellowing of the coating caused by the aromatization of the epoxy ring caused by UV rays. A second drawback of this solution is found in the fact that the ability to prevent or reduce slipping is quickly neutralized by the strong dirt produced by the sand itself, which traps all types of dirt. For these and other reasons, it is a solution that is used only in industrial environments where frequent water pressure cleaning of the walking surfaces is allowed.

The main aim of the present invention is to provide a non-slip coating product for the treatment of walking surfaces, relative use, preparation method and production kit capable of solving the drawbacks and problems encountered in the solutions of the known art described above.

Within the scope of the main aim outlined above, an important object of the present invention is to provide an anti-slip paint product capable of obtaining a suitable and effective anti-slip coating for the majority of walking surfaces.

The peculiarity of this product consists in the fact that this first component includes a mixture composed of a polyurethane glue base, of particle aggregates of a thermoplastic nature, differentiated granulometry and dosage in proportion to the roughness levels to be given to a coating obtained with this painting product. anti-slip and a wetting additive.

This peculiarity allows to achieve the aim of the invention, which consists in a suitable and effective anti-slip coating for the majority of walking surfaces, because, as will be appreciated further on, the polyurethane glue generally ensures optimal adhesion of the anti-slip coating to the underlying surface. external layer of a walking surface and the differentiation of particle size and dosage of the particle aggregates makes this product easily modulated to obtain the expected roughness of a walking surface.

Furthermore, this peculiarity still allows one of the objects of the invention to be achieved, which consists in maintaining the external appearance and coloring of a walking surface unaltered both in internal and external applications, because, as will be appreciated from the following description, the components of this product are absolutely transparent and do not react to UV rays.

Lastly, this peculiarity still allows one of the objects of the invention to be achieved, which consists in the production of a resistant and durable coating for a walking surface, because as it will be appreciated from the following description, the polyurethane glue base and the granulometric choice and of dosing of particle aggregates represent on the whole an ideal combination to ensure resistance and longevity to a non-slip coating thus created.
