Abstract

The present invention relates to a transparent, polyurethane-based biocidal coating for use on non-porous surfaces of healthcare construction elements, food industries, equipment, and furniture. The purpose of this invention is to inhibit the growth of microbes, bacteria, fungi, viruses, and yeasts, thereby preventing the spread of biofilm. This invention provides a proactive measure in the permanent antibacterial protection of the surfaces to which it is applied.

Description

RECUBRIMIENTO BIOCIDA TRANSPARENTE PARA SUPERFICIES NO POROSAS  BIOCIDE TRANSPARENT COATING FOR NON-POROUS SURFACES
La presente invención consta de composiciones, método de uso y uso final de un recubrimiento transparente de poliuretano en base acuosa, con aditivos orgánicos/inorgánicos, para uso en superficies no porosas con efecto biocida. The present invention consists of compositions, method of use and final use of a transparent coating of aqueous-based polyurethane, with organic / inorganic additives, for use on non-porous surfaces with biocidal effect.
SECTOR DE LA TÉCNICA SECTOR OF THE TECHNIQUE
Esta invención pertenece al sector de la salud, alimentación, etc. en prevención de la proliferación de microbios, bacterias, virus y levaduras que pueden producir contaminaciones cruzadas en superficies. This invention belongs to the health, food, etc. sector. in prevention of the proliferation of microbes, bacteria, viruses and yeasts that can produce cross contamination on surfaces.
ESTADO DE LA TECNICA ANTERIOR El uso de biocidas ha sido generalizado por el hombre en la historia de la humanidad, los propios Romanos usaban recipientes metálicos en plata para preservar el agua de posibles contaminaciones. STATE OF THE PREVIOUS TECHNIQUE The use of biocides has been widespread by man in the history of mankind, the Romans themselves used silver metal containers to preserve water from possible contamination.
En la actualidad, los biocidas se usan como aditivos en distintos procesos industriales para la fabricación de objetos con protección bacteriana o desinfectantes. Los tipos de aditivos pueden ser de dos tipologías químicas bien definidas: Orgánicos e Inorgánicos. At present, biocides are used as additives in different industrial processes for the manufacture of objects with bacterial protection or disinfectants. The types of additives can be of two well-defined chemical typologies: Organic and Inorganic.
Las variables pueden ser múltiples, en función del efecto deseado y microorganismos a combatir, cada fabricante interpreta las necesidades del mercado y adecúa los biocidas y adecúa productos según sus intereses técnicos/comerciales y de mercados estratégicos. The variables can be multiple, depending on the desired effect and microorganisms to combat, each manufacturer interprets the needs of the market and adapts the biocides and adapts products according to their technical / commercial interests and strategic markets.
La realidad de nuestra sociedad es que un proyectista tipo Ingeniero/Arquitecto, no conoce las necesidades reales de la medicina, aporta a las superficies construidas dos soluciones básicas y sencillas. La primera en paredes y techos pintura tradicional y la segunda, en el resto de superficies, materiales lisos, no porosos y fácilmente limpiables por los desinfectantes tradicionales. Estos materiales pueden ser PVC, acero Inox, melamina, cerámica, etc. The reality of our society is that an engineer / architect type designer, does not know the real needs of medicine, provides two basic and simple solutions to the constructed surfaces. The first in walls and ceilings traditional paint and the second, in the rest of surfaces, smooth materials, non-porous and easily cleanable by traditional disinfectants. These materials can be PVC, stainless steel, melamine, ceramics, etc.
En el sector sanitario, intervienen distintos industriales proveedores de materiales de construcción, equipamiento médico y mobiliario. Cada empresa tiene una visión estratégica distinta, es materialmente imposible dotar a todos los elementos constructivos y de equipamiento de los aditivos bactericidas idóneos para evitar la proliferación del biofilm en áreas sanitarias y/o industrias alimentarias. Podemos añadir incluso otros sectores susceptibles de protección bacteriana como: vehículos de transporte de pasajeros o alimentos continentales o intercontinentales como navios, trenes, aviones, etc. In the health sector, different industrial suppliers of construction materials, medical equipment and furniture are involved. Each company has a strategic vision differently, it is materially impossible to provide all the construction and equipment elements with suitable bactericidal additives to prevent the proliferation of biofilm in sanitary areas and / or food industries. We can add even other sectors susceptible to bacterial protection such as: passenger transport vehicles or continental or intercontinental food such as ships, trains, airplanes, etc.
BREVE DESCRIPCION DE LA INVENCIÓN BRIEF DESCRIPTION OF THE INVENTION
La presente invención tiene por objeto el establecer un método para proteger de forma permanente las diversas superficies no porosas de cualquier tipo de elemento constructivo o equipamiento, mediante un recubrimiento que se aplica en estado liquido y endurece en contacto con el aire ofreciendo un aspecto transparente, prácticamente desapercibido para el ojo humano una vez endurecido, y que actué como inhibidor de microorganismos y/o microbios. The present invention aims to establish a method to permanently protect the various non-porous surfaces of any type of construction element or equipment, by means of a coating that is applied in a liquid state and hardens in contact with the air offering a transparent appearance, practically unnoticed by the human eye once hardened, and acted as an inhibitor of microorganisms and / or microbes.
La composición de este recubrimiento puede ser de poliuretano en base acuosa, poliuretano-acrílico en base acuosa o acrílico en base acuosa, modificado con agentes biocidas orgánicos y/o inorgánicos. Las características de este recubrimiento son: elevada adhesión sobre superficies no porosas y su elevada transparencia. The composition of this coating may be of water-based polyurethane, water-based polyurethane-acrylic or water-based acrylic, modified with organic and / or inorganic biocidal agents. The characteristics of this coating are: high adhesion on non-porous surfaces and its high transparency.
La aplicación de este recubrimiento podrá ser realizada a brocha, rodillo, nebulización, o por pistola de eléctrica/neumática de pulverización. The application of this coating can be done by brush, roller, fogging, or by electric / pneumatic spray gun.
La finalidad de este recubrimiento biocida es inhibir la proliferación de biofim y/o proliferación de microorganismos tipo: bacterias Gram positiva / Gram negativa, hongos, virus o levaduras. The purpose of this biocidal coating is to inhibit the proliferation of biofim and / or proliferation of microorganisms type: Gram positive / Gram negative bacteria, fungi, viruses or yeasts.
