Abstract

COMPOSIçáO DE FLUIDO LUBRIFICANTE ECOLóGICO, BIODEGRADáVEL E ANTICONGELANTE PARA SISTEMAS HIDRAULICOS, a qual compreende um glicol, inibidores de corrosão e antiespumante, composição esta que deve ser diluída em água, previamente ou já no sistema hidráulico, incluindo o amortecedor, preferencialmente na concentração de 30% a 70%volume desta composição e 30% a 70% volume de água.

Description

"COMPOSIÇÃO DE FLUIDO LUBRIFICANTE ECOLÓGICO, BIODEGRADÁVEL E ANTICONGELANTE PARA SISTEMAS HIDRÁULICOS".
A presente patente de invenção refere-se a uma novacomposição de fluido lubrificante para sistemashidráulicos, dentre eles, amortecedores, composição estapara ser diluída em água, resultando num fluidoecologicamente correto, biodegradável, e anticongelante,mantendo todas as características físico-químicasessenciais para seu funcionamento dentro das normastécnicas de segurança e de bom desempenho.
Conforme é do conhecimento da técnica, os fluidospara sistemas hidráulicos (dentre eles, os fluidos paraamortecedores) disponíveis no mercado apresentam, em suacomposição, e constituindo seu principal componente, óleobásico mineral ou uma mistura de óleos básicos minerais.
Entretanto, a biodegradabilídade destes componentesé considerada baixa, isto é, "não facilmentebiodegradável", de forma que o descarte do material deveser feito conforme resolução CONAMA 362.
É um objetivo da presente invenção a produção deuma composição de fluido lubrificante que apresentebiodegradabilídade maior que a dos atuais produtosdisponíveis no mercado e, consequentemente, que possa serencaminhado às estações de tratamento de produtosconsiderados "facilmente biodegradáveis", sendo, portanto,descartado de maneira diferente do que estabelecido naresolução supracitada.Outro objetivo da presente invenção é a obtenção deum fluido lubrificante que funcione nas mais baixastemperaturas (abaixo de -45°C), fator este que torna esteproduto de uso universal, evitando que seja necessária amanutenção de estoque de diferentes outros produtos.
Para tanto, de acordo com a presente invenção, acomposição de fluido lubrificante ora inovada, que deve serdiluída em água, previamente ou já no sistema hidráulico,incluindo o amortecedor, preferencialmente na concentraçãode 30% a 70% volume desta composição e 30% a 70% volume deágua, compreende:
a) uma quantidade maior de glicol, tais comomonoetilenoglicol; monopropilenoglicol; dietilenoglicol ;dipropilenoglicol; e outros glicóis; o glicol tem porfinalidade proporcionar as características debiodegradabilidade, lubrificante e anticongelante do fluido(produto final); devido às suas características debiodegradabilidade, o fluido pode ser destinado às estaçõesde tratamento de produtos considerados "facilmentebiodegradáveis", e pode ser utilizado de maneira universal,pois funciona inclusive em baixas temperaturas (mesmoabaixo de -45°C);
b) uma quantidade menor de inibidores de corrosão, taiscomo pacote de sais orgânicos, triazóis e surfactantes,nitrito de sódio, pacotes de sais inorgânicos, triazóis,quelantes e tensoativos, benzoato de sódio, bórax, aminas,amidas, ácido cítrico, ácido dodecanodióico; os inibidoresde corrosão têm por finalidade evitar a corrosão do sistemahidráulico em função da presença de água no sistema, nascondições de operação considerada normal;
c) um antiespumante, tais como pacote de hidrocarbonetos,ácidos graxos vegetais e glicóis, isento de silicone;fluido de silicone; dimeticone; polidimetilsiloxano;solução aquosa de polidimetilsiloxano; o antiespumante temcomo função evitar a formação de espuma que se daria com oingresso de ar dentro do sistema durante o regime detrabalho; a presença de espuma causa falha na lubrificaçãoe, portanto, deve ser evitada.
O objeto da presente Patente de Invenção é uma"COMPOSIÇÃO DE FLUIDO LUBRIFICANTE ECOLÓGICO, BIODEGRADÁVELE ANTICONGELANTE PARA SISTEMAS HIDRÁULICOS", composiçãoesta solúvel em água e que, na forma concentrada,compreende:
a) glicol, tais como monoetilenoglicol;monopropilenoglicol; dietilenoglicol; dipropilenoglicol; eoutros glicóis; em uma proporção em massa situada entre89,970% e 99,699%, preferivelmente 94,994%;
b) inibidores de corrosão, tais como pacote de saisorgânicos, triazóis e surfactantes, nitrito de sódio,pacotes de sais inorgânicos, triazóis, quelantes etensoativos, benzoato de sódio, bórax, aminas, amidas,ácido citrico, ácido dodecanodióico; em uma proporção emmassa situada entre 0,3% e 10,0%, preferivelmente 5,0%;
c) antiespumante, tal como pacote de hidrocarbonetos,ácidos graxos vegetais e glicóis, isento de silicone;fluido de silicone; dimeticone; polidimetilsiloxano;solução aquosa de polidimetilsiloxano; em uma proporção emmassa situada entre 0,001% e 0,030%, preferivelmente0,006%.
A composição de fluido lubrificante ora inovadapode ser fornecida na forma concentrada para posteriordiluição em água, ou fornecida já diluída, sendo que estadiluição deve ocorrer, preferencialmente, na concentraçãode 30% a 70% volume da composição e 30% a 70% volume deágua.
A composição de fluido lubrificante ora inovadaapresenta as seguintes especificações de funcionamento edesempenho, ou seja, as seguintes características físico-químicas: aspecto visual límpido; coloração variando doincolor ao amarelo claro; viscosidade cinemática a IOO0Centre 2 cSt e 10 cSt; solubilidade total em água; ponto defulgor mínimo de 90°C; ponto de fluidez máximo de 45°Cnegativos; e índice de acidez máximo de 2 mg KOH/g.
