Abstract
patente de invenção: "composição lubrificante". a presente invenção refere-se a certos compostos de aminas estericamente bloqueadas nh de fórmula (i) ou (ii), em que r é um grupo alquila reto ou ramificado de 7 a 17 átomos de carbono e em que n é um numeral de 6 a 18, compostos estes que são adequados para uso como estabilizantes em composições lubrificantes. as aminas estericamente bloqueadas não são agressivas a anéis em o ou vedações de fluoroelastômeros.
Description
Relatório Descritivo da Patente de Invenção para "COMPOSIÇÃO LUBRIFICANTE". A presente invenção refere-se a composições lubrificantes estabilizadas contra degradação oxidativa via incorporação de certos estabilizan-tes de aminas estericamente bloqueadas. As composições lubrificantes exibem excelentes resultados com relação a dilatação de vedação.
As Patentes norte-americanas 5.073.278 e 5.273.669 ensinam a estabilização de composições lubrificantes com uma certa amina aromática e pelo menos uma amina estericamente bloqueada. A Patente norte-americana Ns 5.268.113 descreve lubrificantes estabilizados pela adição de uma amina estericamente bloqueada e um fe-nol.
Sabe-se adicionar estabilizantes a lubrificantes com base em ó-leos minerais ou sintéticos a fim de aperfeiçoar suas características de desempenho. Antioxidantes são de particular importância. Degradação oxidan-te de lubrificantes desempenha um significativo papel especialmente em ó-leos para motores devido às altas temperaturas predominentes nas câmaras de combustão dos motores e à presença de, além de oxigênio, óxidos de nitrogênio que atuam como catalisadores de oxidação.
Compostos de amina bloqueada são eficazes estabilizantes para lubrificantes. Entretanto, eles não são geralmente empregados devido a efeitos danosos tal como dilatação de vedação. A presente invenção refere-se à estabilização de composições lubrificantes com uma classe específica de compostos de amina bloqueada. As presentes composições lubrificantes não são agressivas a vedações. A presente invenção refere-se a uma composição lubrificante estabilizada que compreende um óleo de base mineral ou um óleo de base sintética ou uma mistura de um óleo de base mineral e um óleo de base sintética; e pelo menos um composto de amina estericamente bloqueada de fórmula (II), em que R é um grupo alquila reto ou ramificado de 7 a 17 átomos de carbono e n é um numeral de 6 a 18. O grupo alquila R é linear ou ramificado e consiste em, por e-xemplo, 7, 8, 9, 10, 11, 12, 13,14, 15, 16 ou 17 carbonos. O numeral n é, por exemplo, 6, 8,10, 12,14, 16 ou 18.
As aminas estericamente bloqueadas são conhecidas e são preparadas de acordo com métodos conhecidos no estado da técnica. Por exemplo, as presentes aminas bloqueadas são ésteres 2,2,6,6-tetrametilpiperidin-4-ólicos de ácidos carboxílicos alifáticos, por exemplo, os ésteres de ácido láurico ou ácido esteárico.
De acordo com uma modalidade preferida, a invenção refere-se a composições em que as aminas bloqueadas de fórmula estão presentes.
Lubrificantes de acordo com a presente invenção são fluidos funcionais, isto é, lubrificantes, fluidos hidráulicos ou fluidos de usinagem metálica.
Lubrificantes são, em particular, óleos à base de óleos minerais (classificações API Grupos I, II, III, Grupo IV, incluindo óleos gasosos a líquidos (GTL)) ou óleos de base sintética, tal como é normalmente usado para a produção de lubrificantes. Óleos sintéticos poderão ser, por exemplo, éste-res de ácidos policarboxílicos ou de polióis; eles poderão também ser poliés-teres alifáticos ou poli-a-olefinas, silicones, ésteres de ácido fosfórico ou po-lalquilenoglicóis. O lubrificante poderá também ser uma graxa baseada em um óleo e um espessante. Tais lubrificantes são descritos, por exemplo, in D. Klamann "Schmierstoffe und artverwandte Produkte" ("Produtos lubrificantes e afins"), Verlag Chemie, Weinheim, 1982.
Exemplos são lubrificantes e fluidos hidráulicos baseados em óleo mineral ou lubrificantes sintéticos ou fluidos hidráulicos, em particular aqueles que são derivados de ésteres carboxílicos e que são usados a temperaturas de 200°C e acima destas.
Exemplos de lubrificantes sintéticos abrangem lubrificantes baseados em um diéster de um ácido dibásico com um álcool monovalente, por exemplo, sebacato de dioctila ou adipato de dinonila, um triéster de trimeti-lolpropano com um ácido monobásico ou uma mistura desses ácidos, por exemplo, tripelargonato de trimetilolpropano, tricaprilato de trimetilolpropano ou misturas dos mesmos, um tetraéster de pentaeritritol com um ácido monobásico ou com uma mistura desses ácidos, por exemplo, tetracaprilato de pentaeritritol, ou um complexo éster de ácidos monobásicos e dibásicos com alcoóis poliídricos, por exemplo, um complexo éster de trimetilolpropano com ácidos caprílico e sebácido ou uma mistura dos mesmos.
Particularmente adequados são, além de óleos minerais, por exemplo, poli-a-olefinas, lubrificantes baseados em ésteres, ou fosfatos, gli-cóis, poliglicóis e polalquilenoglicóis e misturas dos mesmos com água.
As aminas estericamente bloqueadas desta invenção são, em particular, não agressivas a vedações elastoméricas.
As vedações são, em particular, um elastômero de fluorpolímero usado em anéis em O e outros artigos. Os "fluoroelastômeros" são categorizados sob ASTM D1418 e ISO 1629, designação de FKM, por exemplo. Os fluorelastômeros compreendem copolímeros de hexafluorpropileno (HFP) e fluoreto de vinilídeno (VDF de VF2), terpolímeros de tetrafluoretileno (TFE), fluoreto de vinilideno e hexafluorpropileno, éter perfluormetilvinílico (PMVE), copolímeros de TFE e propileno e copolímeros de TFE, PMVE e etileno. O teor de flúor varia, por exemplo, entre cerca de 66 e cerca de 70% em peso. FKM é borracha de flúor do tipo polimetileno que apresenta substituinte flúor e grupos perfluoralquila ou perfluoralcóxi na cadeia polimé-rica.
Consequentemente, um objetivo preferido da invenção é uma composição lubrificante estabilizada que está em contato com um fluoroelas-tômero e que compreende um óleo de base mineral ou um óleo de base sintética ou uma mistura de um óleo de base mineral e um óleo de base sintética e pelo menos um composto de amina estericamente bloqueada de fórmula (I) ou (II), em que R é um grupo alquila reto ou ramificado de 7 a 17 átomos de carbono e n é um numeral de 6 a 18.
As aminas estericamente bloqueadas de acordo com esta invenção são misturadas com os lubrificantes em uma quantidade de cerca de 0,01 a cerca de 5% em peso, por exemplo, de cerca de 0,05 a cerca de 3% em peso, por exemplo, de cerca de 0,1 a cerca de 2% em peso, com base no peso do lubrificante.

Exemplo A superioridade das aminas estericamente bloqueadas reivindicadas sobre outros aditivos similares de aminas estericamente bloqueadas é ilustrada pelo exemplo seguinte. Um óleo 5W-30 para motores contendo 0,08% de P é suplementado com aditivo suficiente de amina estericamente bloqueada para elevar o número total de bases, conforme medido por ASTM D 4739 por duas unidades. Aditivo de amina A é adicionado em um nível de tratamento de 1,0 por cento em peso e aditivo de amina B é adicionado em um nível de tratamento de 1,2%. Os óleos são agitados a 60°C por uma hora para assegurar homogeneidade. As formulações são testadas de acordo com procedimento de compatibilidade de elastômeros CEC- L-39-T-96. Os resultados do teste CEC- L-39-T-96 dessas formulações com uma borracha fluorada FKM são encontrados abaixo. Ambas as aminas afetaram o elastô-mero de borracha. A magnitude do efeito da amina A sobre força de tração e alongamento no ponto de ruptura tornou-a totalmente inadequada para uso em relação a especificações tais como aquelas de ACEA. A amina B apresenta muito menos efeito sobre a borracha fluorada - indicando que é adequada para uso em óleos para motores.
