Embodiment 1

[0053] Embodiment 1, the additive composition that improves lubricant performance, by C 60 Fullerenes react with hydroxyl groups to give C 60 (OH) 8~15 or C 60 (OH) 24~26 , and then from the short-chain carboxylic acid C 1~5 Esterification product C obtained after COOH catalyzed esterification of hydroxyl groups 60 (OOC-R) 8~15或24~26 , as component A of this composition, it contains component B, component C, component D and component E at the same time. Component B is neopentyl polyol ester; component C is isooctyl sebacate; component D is dinonyl diphenylamine; component E is dimethylphenol paraester. The weight ratio of each component is: component A: 5, component B: 6, component C: 6, component D: 15; component E: 15.

Embodiment 2

[0054] Embodiment 2 is basically the same as Embodiment 1, but the weight ratio of each component is: component A: 0.1, component B: 2, component C: 2, component D: 10; component E: 10.

Embodiment 3

[0055] Embodiment 3 is basically the same as Embodiment 1, but the weight ratio of each component is: component A: 10, component B: 10, component C: 10, component D: 20; component E: 20.

Abstract

The invention relates to an additive composition for improving the performance of lubricant, and a preparation method and application method thereof. The preparation method comprises the following steps: performing hydroxylation reaction for C60 fullerene to obtain C60(OH)8-15 or C60(OH)24-26, then catalytically esterifying the hydroxyl by virtue of short chain carboxylic acid C1-5COOH to obtain an esterification product C60(OOC-R)8-15 or 24-26 which is adopted as a component A, wherein the additive composition also comprises an ester dissolving agent and an antioxidant synergistic agent, andthe weight ratio of the three components, i.e., a weight ratio of component A to ester dissolving agent to antioxidant synergistic agent is (0.1 to 10): (2 to 20): (10 to 40). The additive compositiondoes not comprise water, sulfur, phosphorus, chlorine and mechanical impurities and is environment-friendly; and the additive composition has good wear resistance and friction reduction performance:the friction coefficient of the lubricating oil is decreased by 18.8 percent to 34.3 percent, an average grinding spot diameter is reduced to 0.49, and the oxidation induction period is increased by one time or more in the existence of the high-temperature high-pressure oxygen. After the lubricating grease is added, when the device is in an idle state, the input current can be decreased by 16.3 to20.3 percent.

Description

technical field [0001] The invention relates to an additive, in particular to an additive composition for improving lubricant performance. The present invention also relates to methods for preparing and using the additive composition for enhancing lubricant performance. This product is used in the field of relative motion lubrication of various parts, and the added carrier includes fluid lubricating oil, solid and semi-solid lubricating grease. Background technique [0002] Lubricating additives, especially organic polar compounds containing sulfur, phosphorus, and chlorine are used as anti-wear agents. Such compounds cannot form a firm compound film on the metal surface under high pressure. It has a lower melting point than metals. When metals When the temperature rises due to the pressure of the friction joint, this layer of compound film melts to form a smooth surface, reducing friction and wear on the metal surface. The types of anti-wear agents include: organic chlori...
