Description
본 발명은 염기성 오일 및 폴리우레아(폴리카바미드)합성물 및 첨가물을 포함하는 저 비율의 침전농축물로 합성된 윤활유에 관한 것이다.
상기 윤활유는 예를 들어 DE-OS 33 03 442에서 염기성 오일이 나프텐 또는 파라핀 기초 염기성 오일과 같은 광유 또는 인공유이고, 침전농축제는 장쇄 알리파틱 모노아민, 바람직하게는 16 내지 24탄소분자인 3-이소시아네이트를 최소한 갖는 이소시아네이트 반응물이다.
상기 윤활유는 150℃ 내지 160℃에서 오랜 시간 사용될 수 있다.
에스테르를 염기성 오일로 함유하고 0.1㎜에서 220 내지 385의 침투도를 가지며 침전농축제가 방향족 모노-또는-디-이소시아네이트 및 8 내지 24탄소분자를 갖는 알킬-, 알케닐 잔기 또는 6 내지 10탄소분자를 갖는 아릴잔기로 이루어진 유사합성물이 특히 소음을 줄이는 특성을 갖는 것으로 알려졌는데, 이러한 특성은 레코드 플레이어, 카세트 및 비데오 카세트 레코더 등과 같은 전자제품의 기계적인 작동부분에 특히 중요하다. 그러한 윤활유 조제품은 특히 마찰방지 베어링에 특히 적당한 것으로 이것은 180℃까지 견딘다.
윤활유는 염기성 오일 및 폴리우레아(폴리카바미드) 및 그것의 첨가제를 포함하는 저 비율의 침전농축제로 합성될 수 있는 것으로 염기성 오일은 하나 또는 그 이상의 C7-C18-알카놀을 갖는 방향족 디-,트리-, 또는 테트라 카복실산 에스테르이고, 침전농축제가 다음과 같은 일반식의 반응물과 H2N-R식을 갖는 아민과 반응물이다.
A(B)n (1)
상기식에서 A=CH4-n, B=방향족 모노- 또는 디-이소시아네이트잔기, n=1-3, R=8 내지 22 탄소원자를 갖는 알킬 또는 알케닐잔기 또는 6 내지 10 탄소원자를 갖는 아릴잔기이고, 염기성 오일과 침전농축제의 혼합물은 0.1㎜에서 220 내지 385의 침전도를 갖는다.
상기 윤활유는 DIN ISO 2137에 따라 NLGI-카테고리 3 내지 0와 일치한다. 바람직한 염기성 오일은 40℃에서 18 내지 400㎟/s의 점성을 갖는다.
바람직한 윤활제는 염기성 오일의 프탈릭산, 트리메레틱산 또는 피로멜리틱산 산의 C8내지 C13알코올에스테르이고, 침전농축제가 C6내지 C22-알킬아민, 아민 또는 나프탈아민을 갖는 2,4- 및 2,6-톨루엔 디이소시아네이트 혼합물과 같은 메틸렌-비스-페닐이소시아네이트 또는 톨루엔 디-이소시아네이트반응/변환물인 것이다.
부식 및 산화를 방지하고, 킬레이트, 라디칼 트랩, UV-변환기 등으로 작용하는 금속의 영향에 대하여 보호하기 위하여 사용되는 첨가제는 기술적으로 상업적으로 이용되고 있다.
소음시험은 특히 시행착오법에 의해 이루어지는데 적절한 마찰방지 베어링은 1800min-1회 운전된다.
소음은 마찰방지 베어링의 바깥 베어링에서 직접 가속레코더에 의하여 측정된다. 장치에 의하여 기록된 오실레이션은 세개의 주파수영역(저 : 50~300Hz, 중 : 300`1,800Hz, 고 : 1,800~10,000Hz)으로 분할된다. 또한 최대 피이크가 기록된다.
측정된 값은 컴퓨터에 의해 측정되고, 참고 윤활제로 측정된 값과 비교된다.
100%에서 일정한 기준값과 비교하여 상대값이 얻어진다. 본 발명에 따른 윤활제는 광유 및 폴리우레아(폴리카바미드)합성물로 구성된 윤활제와 비교하면 전 지역에서 약 100%의 값을 나타내는 것으로 이것은 386%까지 피이크값을 갖는다.
본 발명은 실시예에서 다음과 같이 설명된다.
(A=CH3, n=1, B=방향족 디이소시아네이트, R=6 탄소원자를 갖는 아릴잔기)
103g의 아닐린을 갖는 2,4 및 2,6톨루엔 디이소시아네이트로 구성된 합성물 97g이 프탈산 및 이소머 C13-알코올의 에스테르로 구성된 에스테르 오일 785.9g에서 반응된다. 발열반응이 완료된 후 혼합물은 160℃까지 가열된다. 산업용 산화방지제 5g의 냉각기간동안, 상업용 방부제 5g과 상업용 금속 불활성제 0.5g이 첨가된다.
그리스혼합물은 3-롤(roll)분쇄기에서 반복되는 분쇄에 의하여 균질화 된다. 이러한 균질화 과정은 특히 소음을 감소시키는데 있어서 중요하다. 이러한 방법으로 NLGI-클라세(Klasse) 0 그리스유는 DIN ISO 2137에 따라 생성된다.
생성된 그리스유는 소음 시험벤치에서 시험되는데, 이것은 최대 피이크에 따를 뿐만 아니라 세걔의 주파수 영역에 따라 분화된다.
소음치의 상당한 감소가 광유 및 장쇄를 갖는 폴리우레아(폴리카바미드)합성물로 구성되는 상업용 윤활유와 비교 측정된다.

이러한 방법으로 NLGI-클라세(Klasse) 1 그리스유는 DIN ISO 2137에 따라 생성된다.
생성된 그리스유는 실시예 1과 같이 시험되고 노이즈에 있어서 상업용 윤활유와 비교할때 상당히 감소되었다.
[실시예 3]
실시예 2와 같은 디이소시아네이트 및 아민은 피로멜리트산의 에스테르 및 C-8-알코올 이성질체로 구성되는 에스테르 오일 839.5g과 반응된다. 반응, 첨가제 투여 및 균질화는 실시예 1과 같은 방법으로 일어난다.
NLGI-클라세 1 그리스유는 DIN ISO 2137에 따라 생성된다.
생성된 그리스유는 실시예 1과 같이 시험되고, 노이즈는 상업용 윤활유와 비교하여 상당히 감소된다.
도면 및 표에서 부호 및 값은 다음과 같다.
표 1은 실시예 1 내지 3에 대한 제1도에 따른 윤활유 노이즈 측정값을 나타낸 표이다.
표 2는 제2도에 따른 비교 그리스유에 대한 동일한 실험값을 나타낸 표이다.
