김종호,조원오,김영운,정근우 한국공업화학회 1997 응용화학 Vol.1 No.2
This paper describes the results of analysis, syntheses and evaluation of tetra-urea greases. Tetra-urea greases were prepared by reaction of various isocyanate and various amines with base oil at 80-100℃. The structures and chemical properties of synthesized urea greases were discussed. The performance properties of urea greases included dropping point, penetration, and wear stability.
