"TINTA ΑΝΤΙ - MICROBIANA ZINCO PIRITIONA"."INK ΑΝΤΙ - MICROBIANA ZINCO PIRITIONA".

Refere-se a presente patente de invenção a uma tinta em póantimicrobiana que utiliza o agente antimicrobiano que tem o principio ativo doagente bactericida ZINCO PIRITIONA mínimo 99 % concentração e fórmulaquímica C10H8N2O2S2ZN.The present invention relates to an antimicrobial powder paint using the antimicrobial agent having the active ingredient of the bactericidal agent ZINCO PIRITIONA minimum 99% concentration and chemical formula C10H8N2O2S2ZN.

São conhecidas tintas antimicrobianas que são tintas em pó queutilizam resina poliéster ou resina epóxi, poliuretano utilizadas normalmente emcomposição de tintas em pó e acrescidas usualmente de aditivos, cargasminerais, pigmentos orgânicos e/ou inorgânicos e agentes de cura paraendurecimento, sendo a novidade a introdução como agente antimicrobiano oZINCO PIRITIONA.Antimicrobial paints are known as powder paints which use polyester resin or epoxy resin, polyurethane commonly used in the composition of powder paints and usually added with additives, mineral fillers, organic and / or inorganic pigments and curing agents. antimicrobial agent oZINCO PIRITIONA.

A necessidade de tintas que incorporam antimicrobianos é desejávelem equipamentos e móveis utilizadas em hospitais, clínicas médicas, indústriasde medicamentos, produtos alimentícios e outros e já vem sendo utilizadas taistintas.The need for inks that incorporate antimicrobials is desirable in equipment and furniture used in hospitals, medical clinics, the drug, food and other industries, and is already being used.

Tintas com antimicrobianos são utilizados não apenas para evitar aproliferação de bactérias, micróbios, como também na proteção da própria tintacontra o ataque de organismos, como algas, com previsto por exemplo naspatentes PI0010785-9 e PI0014775-3, da Troy Technology Co., ou na previstanas patentes PI9407853-0 e PI9807254-4 da Arch Chemicals Inc., na formulaçãoprevista na patente PI9508562-9 de Proguard, Inc., na patente PI0303682-0 deWeg Indústrias S/A Química, ou na patente PI0406138-1 da UniversidadeFederal de Santa Catarina e ainda na patente PI0409420-4 da Merck PatentGmbH.Antimicrobial paints are used not only to prevent proliferation of bacteria, microbes, but also to protect the ink itself against attack by organisms such as algae, as provided for in Troy Technology Co., PI0010785-9 and PI0014775-3, or in Arch Chemicals Inc.'s anticipated patents PI9407853-0 and PI9807254-4, in the formulation provided in Proguard, Inc. patent PI9508562-9, Chemical Industries SA / A patent PI0303682-0, or Federal University patent PI0406138-1 Santa Catarina and also in the patent PI0409420-4 of Merck PatentGmbH.

Verifica-se que a aplicação de agentes antimicrobianos em tintas émuito comum, incluindo as tintas em pó a base de diversos produtos tais comopoliéster em diversas formas, epóxi, poliuretanos entre outros.It is found that the application of antimicrobial agents in paints is very common, including powder paints based on various products such as polyester in various forms, epoxy, polyurethanes among others.

O objetivo da presente patente é obter uma tinta antimicrobiana quetem como princípio ativo conhecido como ZINCO PIRITIONA, cuja fórmula éCioH8N202S2ZN, que tem uma grande eficácia antimicrobianaThe aim of the present patent is to obtain an antimicrobial paint having as active ingredient known as ZINCO PIRITIONA, whose formula is CioH8N202S2ZN, which has great antimicrobial efficacy.

Na mistura com a tinta em pó, usando a composição da tinta em póhíbrida com poliéster, e/ou epóxi e/ou resina poliéster carboxilada 10 a 70 %,resina epóxi 15 a 60%, agente de cura endurecedor 0,1 a 1 %, aditivosespeciais, cargas minerais como sulfato de bário e barita 0 a 40 %, pigmentosorgânicos 1 a 10 %, e pigmentos inorgânicos 0 a 15 %, e aditivo com agenteantimicrobiano 0 a 3 % consistindo a novidade propriamente dita no uso doprincípio ativo do agente bactericida ZINCO PIRITIONA mínimo 99 %concentração e fórmula química CioHeN2O2S2ZN.In admixture with the paint powder using the polyester, and / or epoxy hybrid powder paint composition and / or 10 to 70% carboxylated polyester resin, 15 to 60% epoxy resin, 0.1 to 1% hardening curing agent , special additives, mineral fillers such as barium sulfate and barite 0 to 40%, organic pigments 1 to 10%, and inorganic pigments 0 to 15%, and additive with agenteantimicrobial 0 to 3%, the novelty itself being the active use of the bactericidal agent. ZINCO PIRITIONA minimum 99% concentration and chemical formula CioHeN2O2S2ZN.

A formulação especifica para cada tinta tem aplicações específicascom maior ou menor efetividade.The specific formulation for each ink has specific applications with greater or lesser effectiveness.

O processo produtivo: é igual ao da fabricação de tintas em pó,conhecidos há muitos anos e basicamente inclui a pesagem das matérias-primas e depois encaminhada para homogeneização em um misturador rotativo,em seguida é encaminhado para processo de extrusão aonde as matéria- primasirão se fundir a temperaturas por volta de 150°C através do processo dehomogeneização com sistema por exemplo de rosca dupla e em seguida passapelo cilindro com resfriamento até cerca de -10°C e percorre aproximadamenteseis metros para resfriamento, passando por um triturador que dá a forma dechips ou flakes sendo depois encaminhado para micronização onde é feito amoagem da tinta para se transformar em pó e classificada através de umapeneira rotativa para classificar o tamanho das partículas que tem uma variaçãode 30 a 60 um e em seguida embalado em sacos plásticos.The production process: It is the same as the manufacture of powder paints, known for many years and basically includes the weighing of the raw materials and then sent to homogenization in a rotary mixer, then is sent to the extrusion process where the raw materials melt at temperatures around 150 ° C through the process of homogenization with eg double screw system and then the cylinder with cooling down to about -10 ° C and travels approximately six meters for cooling through a shaping machine dechips or flakes are then micronized where the paint is crushed to powder and graded through a rotating screen to classify the particle size which ranges from 30 to 60 µm and then packed in plastic bags.
