Entretanto, a biodegradabilídade destes componentesé considerada baixa, isto é, "não facilmentebiodegradável", de forma que o descarte do material deveser feito conforme resolução CONAMA 362.However, the biodegradability of these components is considered low, that is, "not easily biodegradable", so that the disposal of the material should be done according to CONAMA resolution 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.It is an object of the present invention to produce a lubricating fluid composition which has a higher biodegradability than current products available on the market and, consequently, which can be routed to the "easily biodegradable" treatment plants and is therefore disposed of differently than Another objective of the present invention is to obtain a lubricating fluid that works at the lowest temperatures (below -45 ° C), which makes this product universal use, thus avoiding the need to maintain stock of different products. .

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:For this purpose, according to the present invention, the composition of a lubricating fluid now innovated, which must be diluted in water, previously or already in the hydraulic system, including the damper, preferably in the concentration of 30% to 70% of this composition and 30% to 70%. % volume of water, comprises:

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);a) a larger amount of glycol, such as monomethylene glycol; monopropylene glycol; diethylene glycol dipropylene glycol; and other glycols; Glycol is intended to provide the characteristics of the biodegradability, lubricant and antifreeze of the fluid (end product); Due to its characteristics of degradability, the fluid can be destined to the treatment plants of products considered "easily biodegradable", and can be used universally, since it works even at low temperatures (even below -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;(b) a smaller amount of corrosion inhibitors such as organic salt package, triazoles and surfactants, sodium nitrite, inorganic salt package, triazoles, chelators and surfactants, sodium benzoate, borax, amines, amides, citric acid, dodecanedioic acid ; Corrosion inhibitors are intended to prevent corrosion of the hydraulic system due to the presence of water in the system under normal operating conditions;

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.c) a defoamer, such as a hydrocarbon-free package of vegetable fatty acids and glycols, silicone fluid; dimethicone; polydimethylsiloxane, aqueous polydimethylsiloxane solution; The defoamer has the function of preventing the formation of foam that would occur when air enters the system during the working regime; The presence of foam causes lubrication failure and should be avoided.
