COMPOSIÇÃO QUÍMICA PARA FABRICAÇÃO DE TINTA COM EFEITO SIMILAR A ESPELHO CHEMICAL COMPOSITION FOR THE MANUFACTURE OF PAINT WITH MIRROR SIMILAR EFFECT
INTRODUÇÃO INTRODUCTION
[001] O presente relatório descritivo de Patente de Invenção refere-se à uma Composição Química Para Fabricação de Tinta com Efeito Similar a Espelho, doravante denominada de Tinta Similar a Espelho, a qual foi desenvolvida visando seu uso no revestimento de placas de materiais plásticos, mais especificamente acrílico e vidros, outorgando- lhe a aparência de espelho e também as características de reflexão de imagens. [001] This descriptive report of the Patent of Invention refers to a Chemical Composition for the Manufacture of Ink with Mirror-Like Effect, hereinafter referred to as Mirror-Like Ink, which was developed aiming its use in the coating of plates of plastic materials , more specifically acrylic and glass, giving it the appearance of a mirror and also the characteristics of image reflection.
[002] Para atender as finalidades previstas, a Tinta Similar a Espelho é constituída por resinas, pigmentos, aditivos e solvente em proporções mais adiante definidas. [002] To meet the intended purposes, Mirror-Like Ink consists of resins, pigments, additives and solvent in proportions defined below.
CAMPO DE APLICAÇÃO APPLICATION FIELD
[003] O campo de aplicação desta Tinta Similar a Espelho refere-se a área de decoração, sobretudo na concepção de ambientes domésticos e comerciais, bem como com fins utilitários, como os encontrados nos retrovisores de automóveis ou apenas para refletir a imagem das pessoas, assim como também na área de segurança em suportes para espelhos instalados em locais de difícil acesso, substituindo os espelhos em função de custos. [003] The field of application of this Mirror-Like Ink refers to the decoration area, especially in the design of domestic and commercial environments, as well as for utilitarian purposes, such as those found in car mirrors or just to reflect the image of people , as well as in the security area in supports for mirrors installed in places of difficult access, replacing mirrors due to costs.
FINALIDADE GOAL
[004] A finalidade desta Tinta Similar a Espelho é a de permitir sua aplicação sobre superfícies transparentes para criar efeito similar ao efeito de um espelho. [004] The purpose of this Mirror-Like Paint is to allow its application on transparent surfaces to create an effect similar to the effect of a mirror.
[005] Dentre outras finalidades viáveis, destaca-se seu uso na segurança mediante aplicação em retrovisores ou em dispositivos conhecidos como espelhos de segurança. [005] Among other viable purposes, its use in security stands out through application in rearview mirrors or in devices known as safety mirrors.
PROBLEMAS A SOLUCIONAR [006] Conforme é de conhecimento geral, o processo de fabricação de espelhos integra muitas fases, desde a limpeza e polimento, até as reações químicas que proporcionam a concepção dos elementos, destacando-se que o mesmo começa com a limpeza do vidro com água comum para que todos os resíduos sejam retirados. Na sequência, uma máquina usa esguichos para aplicar água desmineralizada, livre de sais minerais, que proporciona uma limpeza mais profunda na superfície do vidro. A seguir, o vidro recebe uma camada de prata metálica formada por reações químicas do nitrato de prata. Essa substância adere completamente ao vidro. Na última etapa, uma máquina pulveriza tinta preta atrás da superfície do vidro, protegendo o espelho de ações corrosivas. Acontece então a secagem, que é feita em um forno a gás, a uma temperatura de 90 °C. PROBLEMS TO SOLVE [006] As is common knowledge, the mirror manufacturing process includes many phases, from cleaning and polishing, to the chemical reactions that provide the design of the elements, noting that it begins with cleaning the glass with water common for all waste to be removed. Next, a machine uses nozzles to apply demineralized water, free of mineral salts, which provides a deeper cleaning of the glass surface. Next, the glass receives a layer of metallic silver formed by chemical reactions of silver nitrate. This substance adheres completely to the glass. In the last step, a machine sprays black paint behind the glass surface, protecting the mirror from corrosive actions. Drying then takes place in a gas oven at a temperature of 90°C.
[007] Finalmente e para afastar a possibilidade de corrosão, outra camada de tinta preta é aplicada atrás da superfície do espelho. Dessa vez, o vidro é submetido a uma temperatura de 180 °C. [007] Finally, and to ward off the possibility of corrosion, another layer of black paint is applied behind the mirror surface. This time, the glass is subjected to a temperature of 180 °C.
[008] O processo acima é demorado e envolve um custo operacional alto, além dos diversos problemas de ordem técnica para colocação de marco, instalação, incluindo transporte, o que resulta num produto caro, mesmo quando comprado nas dimensões corretas para instalação em uma sala ou outra dependência, por exemplo. [008] The above process is time-consuming and involves a high operating cost, in addition to the various technical problems for placing the frame, installation, including transportation, which results in an expensive product, even when purchased in the correct dimensions for installation in a room or another dependency, for example.
[009] A Tinta Similar a Espelho tem como finalidade solucionar, de forma integral, todos os problemas relacionados com a instalação de superfícies refletivas destinadas a decoração de ambientes, em substituição a espelhos, já que permite usar uma placa de acrílico ou de vidro transparente, nas medidas do local, aplicar a tinta disponibilizada em aerossol ou em latas para aplicação com pistola. [009] Mirror-Like Ink aims to solve, in an integral way, all problems related to the installation of reflective surfaces intended for decoration of environments, replacing mirrors, since it allows the use of an acrylic or transparent glass plate , according to the measurements of the place, apply the available paint in aerosol or in cans for application with a pistol.
