Description
DESCRIÇÃO
TELHA DE PAVIMENTAÇÃO COMPREENDENDO ΌΜ LIGANTE HIDRÁULICO E
PARTÍCULAS FOTOCATALÍTICAS
CAMPO DA INVENÇÃO A presente invenção refere-se a um ligante hidráulico, uma pré-mistura seca, uma composição de cimento tendo a propriedade melhorada de manter, após a instalação, por longos periodos de tempo, o brilho e a quantidade de cores.
ESTADO DA TÉCNICA
Um das mais importantes utilizações para o cimento (cinza ou branco) é na fabricação dos chamados "cimentos arquitectónicos", ou seja, fundidos em superfícies não tratadas (lisas ou perfiladas) ou tratadas (por exemplo, jacto de areia). Particularmente o cimento branco é utilizado como um elemento decorativo na prefabricação de luz e na produção de ladrilhos. A composição arquitectónica de cimento, especialmente o branco, deve cumprir a exigência, para além de obter boa resistência mecânica e durabilidade com o tempo também as superfícies têm de ter boa aparência e, portanto, ser uniformes em cor e textura. 1 A fim de obter cimentos arquitectónicos tendo cor homogénea e composição constante, é essencial a selecção do material inerte, mas, ao mesmo tempo, as ditas formas de material inerte tem de até 80% da massa de cimento, a superfície de cimento tem uma diferente composição das camadas subjacentes e, portanto, da totalidade da sua massa: o material inerte grosso não aparecem na superfície e esta consiste apenas em pasta de cimento e areia.
Como consequência a superfície de betão fabricada com cimento branco e areia acaba por ser boa, mesmo se o agregado graúdo é mais escuro. A uniformidade da cor da areia é menos importante do que no caso de cimento cinzento de arquitectónico: a constância da cor do cimento branco pode abranger, obviamente dentro de certos limites, as variações de cor da areia. A EP 0590477 refere uma camada de óxido de metal exibindo uma função de actividade fotocatalítica formada sobre a superfície de um material inorgânico arquitectónico, tais como materiais de parede externa, telhados, material de parede interna, material de revestimento, e material do tectos, incluindo vidro, azulejo, cimento, pedra, metal, etc., de modo a fornecer a propriedade de desodorização de um espaço entrando em contacto com o material arquitectónico, e anti-molde, propriedades anti-revestimento e absorção da superfície ultravioleta do 2 material arquitectónico, bem como a manutenção a longo prazo dessas propriedades. A EP 0633064 refere-se a um fotocatalisador composto que compreende um substrato tendo partículas de um fotocatalisador tal como o óxido de titânio, aderente via um adesivo de menor degradação, como um polímero fluorado compreendendo um copolímero de um éster vinílico e/ou éter vinílico e uma f luoroolef ina, ou um silicone à base de polímero ou cimento. PROBLEMA TÉCNICO 0 problema principal das manufacturas em cimento arquitectónico, tanto em cimento cinzento como em cimento branco, diz respeito à manutenção constante com o tempo da a aparência original; é importante adiar o mais possível o processo de envelhecimento natural, devido, essencialmente, à influência de agentes atmosféricos. A protecção destas manufacturas é principalmente realizada com produtos repelentes de água que são aplicados sobre as superfícies em spray ou pincel, como, por exemplo, soluções de silicone, que são estáveis num ambiente alcalino, e, possivelmente, à luz e ao mau tempo. 3
