Polyurea lubricating grease composition and preparation method thereof

摘要: The invention relates to a polyurea lubricating grease composition and preparation method thereof. With total weight of the as benchmark, comprises 7-20% densifier, 79-90% base oil, 1-3% oil soluble nano cerium oxide. As oxide with excellent abrasion resistance is added grease, has lower friction coefficient. wear spot diameter without other antiwear agents about 0.45 in SRV tests, much less than common additive; an obvious anti-attrition effect, can provide pair complete protection, effectively prolongs service life equipment. Furthermore, traditional containing elements such sulfur phosphorus unfriendly environment are reduced use, so that environmental protection performance greatly improved. According method, application lubrication expanded.
